    • The glass panel is fixed onto the front bezel with fourteen magnets around its perimeter.

    • Stick two suction cups to opposing corners of the glass panel.

    • To attach the suction cups we sell, first position the suction cup with the movable handle parallel to the face of the glass panel. While lightly holding the suction cup against the glass, raise the movable handle until it is parallel with the other handle.

    • If your suction cups refuse to stick, try cleaning both the glass panel and the suction cup with a mild solvent such as Windex.

    At this stage and later handling the LCD I found thin cotton gloves helped to reduce smudges

    My GPS unit's car mount suction cup worked nicely here - couldn't find any at the store and didn't want to wait for mail order!

    Two cups would make it easier but one is fine if you place it in the center and are careful to pull the panel straight out.

    Why use suction cups when some finger nails will do the job nicely, though a plastic spudger might work too. Start at a top corner. Prize the glass away from the case and leave finger nails in. Move the other hand along the top edge and then with finger spread peel the screen cover away. Be careful not to twist plastic I suppose, but I've had no difficulties.

    • Gently pull the glass panel straight up off the iMac.

    • The glass panel has several positioning pins around its perimeter. To avoid shearing these pins off the glass panel, be sure to only pull straight up during removal.

    • Be meticulous about cleaning the LCD and the inside face of the glass panel before reinstallation, as any fingerprints or dust trapped inside will be annoyingly visible when the display is on. Placing the glass flat, inside face down, on a fresh aluminum-foil surface is a good way to keep it clean.

    In order to avoid unnecessary smudges and what not I covered the LCD itself with some plastic wrap while doing the hard drive upgrade. When I reinstalled it all I needed to do was blow off a few dust particles.

    robgendreau - 返信

    While you are at it, it is worth cleaning out dust within the case to help with cooling - particularly around the fans and vents.

    For the screen I used a lens cleaner from my camera bag. These have very fine fibers and won't leave detritus.

    Mathew Hendry - 返信

    Note that the front glass panel is quite light. When reassembling I found it impossible to get the LCD free of dust with the computer lying on its back. I had success with standing the computer up, tilting the LCD down as far as it goes, holding the glass panel upright in front of the computer (about 1 foot away), lightly spraying both the LCD and the back side of the glass panel with compressed air, and then attaching the glass panel (with the computer upright). It took me 5 tries before it was completely clean of dust once the front glass was on.

    Note for the less experienced.. the case is plastic and the metal coarse thread screws will easily cut a new thread in the hole if you don't line up the screw in the original thread. Do this a few times and the hole will be stripped and the screw no longer tightens.

    TIP:- place the screw in the hole and rotate BACKWARDS/counter clockwise (for RH threads) until you hear/feel it click/drop into the original thread then tighten the screw down. rotate it a couple times to get the feel of things. If there is any significant resistance you probably don't have the original thread.

    This trick also works on the fine metal thread screws and can help avoid cross threading them.

    I found it helpful to use a few lids from spaghetti sauce jars to hold the different screws. I used a sharpie to mark the inside of the lid w/ location taken from or the step number from directions. Then I placed a small magnet under the lid to hold the screws inside the lid in case I accidentally jostle something on the table. Worked great! You can also use a magnetic knife bar to line up the lids in sequential for the project.

    I cut a hardwood block and drew the outline of the the iMac shape with the base as key. I then drew another two lines at 1/2” and 1” all around from the outline. This done I drilled holes for each screw (12 Outer securing the front bezel to the rear case , and 8 Inner screws securing the display panel to the rear case ). That way I don’t lose any or get them mixed up.

    • Disconnect the microphone cable connector, removing tape as necessary.

    • For the front bezel to sit properly, be sure to tuck the microphone cable and connector into the void next to the camera board.

    I avoided this step by just flipping the housing over and having it lay flat on the table. The tape on mine was on really tight, and I risking ripping the wires out of the connector if I messed with it (I didn't have some really small scissors which might have helped removing it). I would suggest either securing the body of the iMac and the housing to the table you're working on, or somehow securing the housing to the body, so that it doesn't move around accidentally, since it's only hanging on by a very thin wire at that point.

    cklarson -

    Make sure you do not pull this apart by the wires. Have a firm grasp on the plastic parts. Do not force back together. It only goes back together one way. Also, it is crucial when placing the aluminum bezel back in place that this wire is out of the way. It often gets in the way and is easily damaged.

    Kyle Freeman - 返信

    CAUTION - To disconnect the cable, you'll need to support the bezel while you carefully extract slack microphone cable which is tightly tucked within the iMac. (I didn't have this guide's 'notes on' and missed robgendreau's warning - then inadvertently shifted the bezel and busted my microphone cable in this step.)

    Don't forget to pull the microphone cord out before you put the panel back on. Otherwise you will have to go back and remove screws to find that microphone cord

    Melvin Hines - 返信

    As robgendreau says, avoid this whole step by opening the bezel and laying it upside down above the iMac, still connected by the mic cord, just carefully. Then replace the battery, suck/blow out your dust, and carefully rotate the front bezel back over the iMac from where you removed it. No cord manipulation or damage at all!

    • Pull the LCD temperature sensor connector straight up out of its socket on the logic board.

    • If necessary, de-route the LCD temperature sensor cable from behind the logic board.

    • When you remove the LCD, check the routing of the LCD temperature display cable. On reinstalling the display, be sure this cable does not block one of the bottom screws for the front bezel.

    This was the most confusing step, because the video shows MJ just tilting the monitor open, and I had a ribbon cable hooked up to it. Finally figured out that the ribbon cable was connected to the LCD temp sensor cable, and it was neatly tucked under the adjacent fan. Had to pull it pretty hard to get it out from under the fan, and then could tilt the LCD. Instructions are not completely clear about this, only that you may have to reroute the cable around the motherboard.

    I agree, there is no sign of how to remove the bezel (it took me several minutes to understand it was even the bezel that came off here) in these steps (in all the guides for this model, in fact).

    If you rush through the reassembly, it's very easy to miss reconnecting the LCD Temp Display cable. I just did it and one of the fans came on full-speed and stayed there through a new macOS install. Did a Google search and found mention of this symptom. At first I was thinking I switched one or more of the inverter cables but this guide shows that this is not a problem. Once I reviewed this step, the problem was obvious as was the solution. Thanks again, iFixit, for saving my nappy behind.

    I can speak from experience, this cable’s a pain. It came out of where I tucked it and snuck behind one of the bottom screws, which pierced it during reassembly, afterward it would not boot properly. It’ll boot without the cable plugged in, but the fan runs near max. I’m glad it can at least be used while I wait for the replacement cable to ship. What a weird (lazy) design choice from Apple.

    Well, I followed the instructions for right-speaker removal and optical drive fan removal and still couldn't find the right screw. I couldn't hear it rattle either so figured it was wedged somewhere. Using an inspection mirror and flashlight, I finally found it. It had fallen down and wedged between the PCB and the plastic housing (below the ports). I was able to slide it toward the right until it came to the void left by the right speaker where it fell out into my hand.

    I did a HD replacement on my 24 inch iMac. It's basically the same, but it does not have disconnectable invertercables. Instead, there's just one cable that's can't be disconnected.

    • With the display panel still lifted, disconnect the four inverter cables.

    • During reinstallation, place the four inverter cable connectors in voids between components attached to the rear panel so the display panel will sit flush.

    • If you are replacing a hard drive and have an extra set of hands, it is possible to reach in and remove the drive without disconnecting anything but the LCD temp and display connector in the previous step with the LCD in its propped position.

    this is a NO step. This should be removed and not to confuse people. There is no need in removing this cable. If you do, the fan will be loud and will have side-effects. I am warning everyone to stay away from this step and jump to or replace this step with STEP 20 instead.

    Also steps 18 and 19 should not exist either. There should be only STEP 20...remove the entire lock plastic piece that holds together the cable sensor and the sponge with it. That is all you need to and takes you 10 seconds...even using a flat screw driver will do the trick as long as you are not aggressive type and pinch hard on the surface of the hard drive but to the plastic lock piece.

    • If your thermal sensor seems to be stuck to the face of the hard drive, skip to the next step.

    These instructions were awesome! I replaced my hard drive on my iMac in about 1 hour. I would add compressed air and good quality double sided tape to the tools required. I had to leave everything open, and go out to buy these because most of the tape inside was no longer sticky.

    • Use the flat end of a spudger to pry the thermal sensor bracket off the face of the hard drive.

    • If you're replacing your hard drive, transfer this bracket and the thermal sensor to your new hard drive. If the adhesive refuses to stick during reinstallation, apply double-stick tape to the underside of the two flat ears of the thermal sensor bracket.

    Be careful what kind of tape you use. The adhesive used in standard clear tape (especially cheap stuff) can soften when it gets warm causing the sensor to come unstuck.

    I used three strips of duct tape - one either side of the sensor and another over the whole thing, being sure it was flush around all the edges.

    you dont need step 18 and 19. if you remove that sponge then you will need adhesive to put it back after. Just take the whole thing out...no need to remove the thermal sensor cable from the lock piece. Don't complicate things and waste your time. remove the lock piece at once and it will hold both the cable and the sponge that is glued on the top. 5-10 seconds...job done.

    Also...refrain from removing the thermal cable at the other end's socket. leave it in there...again...guys...we are just changing a hard drive....don't complicate things because then the sensor will not detect properly and the fan will spin very loud and will not stop.

    its up to you...if you have time and want to do the job twice, then you know what to do.

    I replaced the Seagate hard drive from my 20" iMac with a Kingston SSD (HyperX 3K 120GB). The Kingston came with a 3.5" adapter that is suited for replacement in a hard drive bay of a standard ATX tower or similar. Unfortunately, the adapter included with my SSD does not have suitable spacing for attachment to the hard drive bracket used to secure a standard sized drive into place.

    For me, it was necessary to attach the SSD to the included adapter and then attach a single screw from the iMac bracket plus one of the Torx pins. As such, my adapter and SSD would pivot -- they are not held securely in place. Since the SSD is not mechanical and should not vibrate like a traditional drive, I felt this was adequate. I could have also used tape or similar to hold it in place. Just be forewarned that the distance between the Torx pins is rather long -- you might face similar challenges when using a smaller 2.5" drive + adapter in your replacement.

Here is another reason to DIY this repair, while Apple's labor fee is reasonable, their warranty policy for repairs is not. If you have a new drive installed at the Apple store, your warranty on the drive is only 90 days. Worse yet, the drives are Apple branded, so you can't go to the hard drive manufacturer if the drive fails on day 91.

When first starting with my OS (Snow Leopard) disk all I got was a whitish or gray screen, not even the mouse. So I started freaking out a bit. I couldn't get the key board to stay on so I kept pushing the keyboard power button while holding the option button and then the mouse arrow came up on the screen. After that the apple sign and then the install procedure started, so I was able to breathe again. So about five in the morning I was able to let it do it's thing and get some sleep. The next day I was able to restore from the external hard drive using Time Machine and so far my IMac 20" 7,1 #2133 is running super fast again probably better than when I got it brand new " if that's possible ". With your instructions on I fixit.com and your videos on YouTube it was pretty darn easy, even for someone like me who has never worked on a computer. The most I've done on a computer I installed a new program (Snow Leopard). Thank you, Tom D.

Instructions worked like a charm on my 24" 2134 (taking into account reader's contributions for Step 9). Someone suggested covering the LCD with clingfilm ("Saranwrap") and this is an awesome idea. I was able to have a helper hold the panel while I worked on the hard drive and got no dust or fingerprints on it at all.

A tip if you are replacing the stock hard drive with an SSD: install the SSD onto its carrier so it'll fit in the space left by the hard drive before starting so your helper doesn't have the opportunity to be sarcastic while waiting for you to do it in the middle of the build :-)

Absolutely fantastic faultless guide. Thanks so much! I succesfully installed a Western Digital 2TB SATA drive to my mac to replace our completely failed drive. I had absolutely no issues, although I could have done with some double sided tape to secure some of the sponge (use ordinary tape doubled over in the end.

I also found 2 ordinary suction cups fromone of those little pull down sun blinds in the car were sufficient to pull the screen off.

All now up and running, fresh install of snow leopard and ilife downloading as I write.

Cant tell you how happy I am to have it all up and working again for just the price of the drive (bought from amazon) and some RAM as why not max it out (Crucial memory)

Thanks Ifixit

This step by step is very complete. Be aware that if you are replacing a hard drive with an SSD type and this one is 2.5-in, you will need a mounting bracket or live in shame by using mounting tape.

Great instructions.

Tip: I sorted all the screws into shot glasses and put little pieces of masking tape near them with the number of the step they correspond to.

Also - Got a cheap set of Torx screwdrivers on amazon, and they turned out to be terrible. Poorly precisioned tips and I had to get a decent set to get the job done. They were just not catching the screws. There was a $4.99 Kobalt "8 in 1" set I got a Lowes that was a much better deal, considering the ones I got were equally priced on Amazon.

Chris Scala - 返信

Best instructions I've found. The entire process turned out to take less than 1 1/2 hours. The only issue I had, like some others, was the tools I had at hand. Once I bought myself a better quality Torx set this went off without a hitch. Thank you for the help! Special thanks to Chris Scala for his tip about separating the screws with shot glasses. I'm taking that tip with me everywhere I go from now on. Worked like a charm!

I have a 500GB hard drive in my 20" (replaced by APPLE during AppleCare). Is there a way to add an SSD to the mix? Much like the video for the late 2011 iMac - putting a second SSD drive behind the optical drive?

Or should I just replace the HD with a smaller SSD and use external storage for iTunes etc.?

Also, with this iMac being so limited in RAM (4GB Max, yes?) Is it worth spending the money and time to upgrade the HD to SSD?

I look forward to hearing your thoughts.

This is an old post, but in case anyone has the same questions:

-Is there a way to add an SSD to the mix? Much like the video for the late 2011 iMac - putting a second SSD drive behind the optical drive?

The hard drive can be replaced with an SSD. There is another guide that shows how to replace the DVD drive with a hard drive.

-Or should I just replace the HD with a smaller SSD and use external storage for iTunes etc.?

That is what I did. I moved my iTunes library to an external drive so a smaller hard drive would be OK.

-Also, with this iMac being so limited in RAM (4GB Max, yes?) Is it worth spending the money and time to upgrade the HD to SSD?

You can actually go to 6GB of RAM. Go to macsales.com and find the RAM options for your model. You should see an option to put in a 4GB and 2GB stick. I have this is my mid-2007 20" iMac. As far as the SSD, I think it makes a huge difference. Startup time went from 1.5 min to 30 seconds. Launching apps is way faster. I am happy I did the upgrade.

This really was a disaster for me. The 2008 iMac 2210 was much more difficult to open, and I almost ruined the computer. I spent well over 3 hours just trying to work the instructions, and I am pretty handy with computers. I finally quit, and tried to follow the instructions to just quit, and when trying to restart, dead. I opened it again, rechecked everything, turned it on, and had a bad monitor picture (low resolution). Third time, rechecked everything again, and it worked, but the monitor now has a slight red shadow tint on one side of the monitor. So, never got the HDD installed, I'm returning it, and probably wind up buying a new Mac Mini. Be careful! And be willing to lose your computer, or pay to have it restored by a professional.

A couple of general tips, based on my experience taking this thing apart twice in two days.

As noted above, the case is plastic, not metal, so you can strip out or misalign the screws if things aren't lined up, particularly the 8 T8s around the display. I used my T6 to align the ears on the display with the screw sockets by gently putting it down the adjacent hole and levering the display so the hole I was working with lined up. You only need to do this once on each side. Once one screw is seated, the others on that side should be lined up.

I was missing my extra pair of hands today so I had to reattach the inverter cables solo. I found it was easier from the top, which was made easy by the fact I was working on a table and could easily get around to the other side. Might just be a question of handedness (I'm a righty) or perhaps I'm just uncoordinated.

paul beard - 返信

I took mine apart a second time to track down why the fan was constantly running at a high speed. I reseated the sensor cables, retaped the sensor to the hard drive, and it persisted. Then I ran the Apple Hardware Test (comes with it on DVD or might be installed) and it showed a bad sensor. I then went for the longer test, got tired waiting for it to complete, restarted, and the noise was gone. Maybe the test reset it? I did an SMC reset to be doubly sure and installed SSDFanControl in case it acts up again.

Your guides are excellent. I was able to resurrect my iMac hardware rather easily. The videos take the fear out of opening the sacred box. Getting the software to work was another thing. Very tedious but worth the effort.

Joshua Rountree -

This guide is not exactly precise for the iMac 24" MA878LL 7,1. There are some differences on the connections of the thermal sensors to the Hard Drive. I find it is not necessary to also disconnect the Thermal sensor from the board location only on the drive so as to move it to the new drive. Reassembly did not go well as far as the microphone cable connection. Whatever did not re-connect as expected did NOT result in a functioning internal microphone. The external input functions with a separate microphone, but the internal is dead. It could be software/driver malfunction or the fact that the tiny miniscule connections at the bezel are so delicate that it will no longer function, even after taking the bezel off 2 more times to insure the connection is correct and using electrical tape to keep the delicate connectors together. Wishing you better 'luck' than I had with this process.

Thank you so much!!!

It took me a while to figure out what was wrong with my computer (I also just put it to the side and forgot about it). Thanks to your site I followed these instructions, paid $50 for a hard drive, and now it is working perfectly. I feel like I got a new computer for $50! Thanks so much.

I concur comments about T6 on Step 8. I have a quality set of Torx bits and the T6 is much too small. The T7 fit perfectly. This isn't a matter of Apple using two different size screws in assembly. It is a matter of the Law of Tolerances, which those with machining experience would know about. I would amend the Tools Required and add T7 (in some instances).

I did it and it took me quite a while. However, this was exclusively because the SSD 2,5 to 3,5" bracket did not fit well. I spend a lot of time finding alternatives and even trying to get SATA extension cables.

In the end I decided to agree with anonymous on Sept 26 2012: a pivoting SSD is good enough. Now installing and everything is going fine.

Really happy with the instructions and tools that I bought from iFixit. Next up: 27" iMac, fitting a secondary drive in there is what I am up to. Yay!

Careful - I followed this recipe very closely and my 2007 iMac is basically toast now. I posted the details here and according to the responses, it's most likely the graphics card. I don't see how I could have damaged that with this recipe but it worked before I opened the iMac and replaced the HDD and I can't get it (the iMac in general, I can't be certain it's the card) to work at all since.

As with any technical project, especially for first-timers like me (first time opening up a "laptop" type of technology like the iMac), a key ingredient is reading through the instructions once or twice before opening up the machine. You want to position yourself mentally before you position yourself physically! The instructions are great, one or two maybe superfluous in some cases. But in the end I have a 2008 iMac 20" with a 250 GB SSD (Toshiba) that performs many routine tasks better than my new iMac at work. I'm really happy with the results! Well worth the small amount of money and effort required.

Keith Gardner - 返信

Great guide, easy to follow. But... I had an issue.

After reassembling my iMac, there was no display! Seemed to be running, but nothing on the display. After taking it apart and checking my connections, back together - still no display.

On closer observation, though, the display is on -- but the back light is not. By point a flashlight at the LCD, the desktop can be seen, but no backlight. I double checked the inverter cables, and they are hooked up properly.

I wonder if I damaged the LCD temperature sensor and this is causing the computer to turn off the backlighting, but this is just a guess.

Any ideas?


Perfect instructions! Just did it today with a help of a friend on an old mid 2007 iMac, replaced the failing 320Gb with 1Tb Seagate. Thanks!

Excellent Guide, I had a little hold up between step 4 and 5. The front bezel didn't seem to be budging, and I didn't want to force something that shouldn't be forced. I flipped the unit on it face ( putting cloth down first!) so I could see the seam. But as the other commenters add, do not pull apart fast and furious, so as to not break the microphone wire. With a little patience and perseverence, the bezel came apart nicely.

I just did this upgrade on my mid-2007 20" iMac. Not too difficult if you take your time. I replaced the 320GB HD with a Crucial MX100 256GB solid state drive. I used the Newer Technology AdaptaDrive 2.5" to 3.5" Drive Converter Bracket and it fit everything perfectly. I would recommend this upgrade for anyone willing to open this machine up. There is a huge difference. My startup time (in Yosemite) went from a minute and a half to thirty seconds. Launching apps is significantly faster. Very worth the time and money.

Guide and Video especially useful, i did not replace with regular HDD, but instead went for 128GB SSD. which since there is no way to secure a small SSD to the current HDD housing, i used sticky-tape to stick it in.

I also had difficulty installing a 2.5" SDD using a Sabrent 2.5" SSD & SATA hard drive to desktop 3.5" bay bracket. The cables inside the iMac are just long enough for the original 3.5" drive and not long enough to reach a 2.5" drive in this particular bracket. I had to settle with an SSD held into the bracket at an angle with two screws. Somewhat shameful, but it's not going anywhere anyway.

I actually swapped drives...with a mid-2007 20" and a mid-2011 21.5" iMac...the newer iMac runs rings around the older 20" speed-wise, but I fear that because the drive is not Western Digital like the original inside the 21.5", that's why the fans run pretty much non-stop now...I can put it to sleep, and the fans quit for a while, but eventually they start up again, and they can be fairly distracting in a quiet room...either have to replace the drive with one that has the internal temp sensor, or live with the fan noise...

Fabulous guide!

Used this for my mid-2009 (EMC 2316) 20" iMac - upgraded to a Samsung 500 GB EVO SSD drive. *Just* finished: took about an hour and a half in toto. Just a couple suggestions:

- you'll have the case open: replace the 3V "button" battery while you're in there: it takes 30 seconds and it's done

- have a can of compressed air handy: you can use it to gently clean out the dust, which will have accumulated on the fan blades over time

- I used Carbon Copy Cloner to clone the HD->SSD drive; it worked almost flawlessly: Google Drive needed to be re-synced (easy). Don't forget to deactivate any software that will complain with a change of HD.

- keep in mind that the process is a bit tedious at times: do this when you are rested and have plenty of time; I propped up a laptop with the iFixIt page next to my iMac as I worked on it and this worked well

John Fisk - 返信

It was great to have a guide to follow, though the instructions ended up being more detailed than necessary. You don't have to unplug all that stuff that is attached to the back of the LCD. The less unplugging the better. We merely unplugged the mic cable to remove the bezel, and the two cable in the top right corner (mark them with a sharpie!), then for the LCD you can carefully tilt the top edge up and brace it up (we used two pencils) like a car hood. Then you'll have just enough space to "get under the hood" and access the hard drive from the top area. You might need to be a little more careful so as not to bump any components, but it's worked better than unplugging. Went back together like a charm! Thanks for the intro though!

I used the guide to replace a broken HD on a 20" 2008 iMac with a 2TB hard drive. The pictures, video, and all of the comments were very helpful. I purchased the tools and the new HD from ifixit. The comments helped to give me the best way to do the entire repair. Everything from wearing cotton gloves when handling the glass, which particular screws are longer, moving the temp sensor, not losing screws(magnetized the screwdriver), to using compressed air to clean the screen before re-assembly, helped to make the repair go flawlessly. I also upgraded the RAM to to 2GB in each slot. You can go up to 6 using a 4GB in the right slot, but 4 works for me. I upgraded to 10.7 Lion. Works like a charm.

Great directions! Thank you for the assistance. This is a very easy repair. No one should be worried, if you follow the directions. A few things. Don't rely on the Command + R or Command + Option+R to get your operating system back. Make a bootable usb and get a wired keyboard. It looks daunting, but with Drivemaker X, the drive is EASY to make and you won't go insane when your computer won't boot. Last thing. The mount makes a difference. I had to really mess with mine to make it work. The connectors don't line up and there isn't any "play" in the wiring at all. Again, do yourself a favor and make sure your adapter is correct before you start. That being said, the actual fix was easy and fun. Made a HUGE difference in speed. Don't need a new computer now. EVO drive is great!

Great guide thanks.

two comments:

on my A1224 EMC 2210 it was T 10 (not T 8) and T 6: the T8 could work but it was loose.

Remark: the four screws at the bottom are longer is is important to mention. as well the screws for the display have a large edge the one on the panel are countersunk screws.

Lastly in addition to the tools I would have recommended an air duster, and since it is open it may be wise to replace the CR 2032.

Fantastic guide. I'd never disassembled an imac before. My old early 2008 imac had become very sluggish. Now, with a 6GB memory and a new 480GB ssd bought from ifixit, it is thoroughly rejuvenated (I am typing on it now!) Two things I'd like to encourage: (1) don't forget to make a bootable usb or drive before you start. Just having a time-machine backup is not enough. I had long ago disposed of my lion startup disk, and was surprised to discover that I could not just restore from my time-machine backup. Fortunately, I had an old boot disk in Maverick, which was enough to get things going (albeit a bit convoluted) . (2) Perhaps the guide could add a few steps about the installation of an SSD into the frame that fits where the old hitachi hard drive was located. E.g - some pictures showing where to stick the thermal sensor (answer: directly on the top of the SSD). I wasn't able to find directions for this on the ifixit site. Highly recommend this upgrade.

If you are planning on installing a "clean" SSD (or HDD), which means the new hard drive has nothing on it (straight out of the box), then you need to make a bootable USB image on a flashdrive with the El Capitan Installer. Instructions for that: https://www.lifewire.com/create-bootable....

You will see that until the drive is formatted. Do you have an installer disk? You may be able to slide by if you can get to your recovery partition. Try holding down [Command] + [R] to get to that. You'll probably need someone to send you an El Capitan [.app] file. Shoot me an email at billyk650@gmail.com if you need that, since I'm pretty sure the App Store no longer allows you to download it if your device is running OS X Sierra.

Decent enough guide if you're careful and somewhat familiar with computer hardware. Only issue I came across was the Orico caddy for my SSD wouldn't take the screws from the old HDD. So for the latch part, I cut off the rubber grommets so I could use the screws that came with it. An SSD isn't mechanical therefore they aren't required. The pegs on the other side were a different matter, so I just left them off. You can get the latch part to engage just to enough to keep it in place. The SSD is lighter and smaller, so with a bit of luck it should stay put. I may address this when I go back in to swap the optical drive for a secondary HDD. Just not sure how…

I need some advice about replacing a 320GB HD with a 500 SSD for my Imac mid-2007. The SSD drive doesn’t require a thermal sensor. What do you do with the sensor that is attached to the original HD? Do you reconnect it and tape it back on the body of the SSD drive?

I have made a bootable OSX El Capitan Flash Drive. What is the sequence for formatting and getting the SSD drive loaded with OSX EL Capitan? Does one plug in the Flash Drive and start the IMac holding the Option key?

I would be grateful for experienced advice.

Pablo Guerrero - 返信

SSDs have built-in S.M.A.R.T. temperature sensors that OSX doesn’t use.

You could set it up two ways:

1) Re-attach the Apple sensor to the SSD. OSX will take charge of everything as usual.

2) Download ‘SSDfanControl’ from https://exirion.net/ssdfanctrl/

That can use either the Apple sensor or the SMART sensor inside the SSD.

You can tweak temperature and fan r.p.m. limits.

Beware there are bugs !


Beware that if you break or choose to remove the old Apple sensor, anyone re-installing OSX in future will be stuck with a noisy fan, unless they learn about SSDfanControl!
