このガイドには、iMacのハードドライブをSSDでアップグレードする手順も記載されています。 Macのファンが正しい速度で動作するように、SSDの温度センサーをインストールする方法について説明します。




  1. ディスプレイの左側、つまり電源ボタンに近い方から始めます。iMacオープニングツールをガラス面とケースの側面の間に差し込みます。
    • ディスプレイの左側、つまり電源ボタンに近い方から始めます。iMacオープニングツールをガラス面とケースの側面の間に差し込みます。

    • iMacオープニングツールのハブ(車輪の中心部)は、ホイールをあまりにも押しすぎないようにします。 別の工具を使用する場合は、ディスプレイに3/8インチ(9.5 mm)を超えて挿入しないでください。アンテナケーブルを切断して重大な損傷を引き起こす危険性があります。

    Would a heat gun make this step easier? Or damage the iMac?

    Clark Green - 返信

    A heat gun wouldn’t help you here as you still need to cut though the adhesive. You also risk damaging the display with the excessive heat.

    Dan -

    Removing the original adhesive is easier than removing newly applied adhesive (e.g., if you have to reopen iMac).  If you should happen to need to reopen the iMac, please use extreme caution and highly consider my suggestions below.

    When using the pizza cutter tool, do the first few steps in reverse starting with step 8.  Starting on the left side is better since this is where the adhesive is narrowest.  The right side has two antennas and the top right has one, see the pictures for step 18-21, they are the brass colored metal rectangles near the edges.  The adhesive on these pieces are wider and therefore have more holding power.  The thickness of the pizza cutter tool is enough to crack the glass.

    Walter Hayden - 返信

    Continuing from my previous comment.  To remove the adhesive on the right side you’ll need to create a very slight gap to give the pizza cutter some more room.  Do this by cutting the adhesive on the left side up and around to the camera.  Before attempting to cut the right side. Carefully slide the plastic cards (I purchased two sets) to ensure the adhesive on the left top and side is completely free.  Now slowly move towards the right side.  After every inch or two of removing new adhesive, slide the card over to create this slight gap.  Be careful to not move the card too close to where the adhesive has not been cut.  You want to create a very slight gap without creating too much pressure.  Use extra caution with approaching the areas where the antenna are since the adhesive is stronger here and will need some additional cutting.  Follow this approach all the way around the right side.  Be careful to not create too much pressure at any one time.  Good Luck!.

    I would highly, highly, highly recommend AGAINST doing this at home. I followed these instructions to a T, and still somehow managed to have the screen not be able to turn on after the hard drive replacement. Then, once you’ve opened your Mac yourself, Apple will refuse to fix anything on the computer, and even other third party, Apple-authorized repair facility will refuse to repair it for you, and you will have to locate a non-authorized Apple repair facility. There, I am having to pay ~$600 to fix things that got screwed up, even though I followed the instructions here to a T, step by step, and did everything slowly and methodically.

    Beware, if you’ve never done this before, that be locked out of ever being able to use an Apple repair facility, or Apple-authorized repair facility, if you mess things up here now.

    I performed this on a Late 2015 iMac and there weren’t any significant differences to these steps, but I did find the repair to be nerve-wracking. My model cost nearly $3,000 and about 10 steps into this guide (which I did fully read ahead of time) I was thinking, “what have I got myself into?” But I didn’t rush and happily I’m typing this on my repaired iMac! I found a video from OWC that was more useful than the photos in this guide for certain steps: https://vimeo.com/139364064

    • 続けて左上部コーナーまでツールを転がします。


    • ディスプレイの左側上部を沿って接着剤を切り込みます。

    The pizza cutter will sink in all the way to the tool handle when the adhesive is full cut, but don’t feel you have to do this in one motion. Some parts cut easier and some require a lot (like 20x) of gentle back and forth.

    Anthony Zimmerman - 返信

    • ディスプレイ上面も同様に続けます。

    • ツールで前後に動かしたり既に切った部分をもう一度切ることで接着剤の切開をより確実にすることができます。


    • ディスプレイの右上面周囲の角もツールで押して切開します。


    • ディスプレイの右端にツールの車輪を押し下げます。


    • ディスプレイの右下角までツールを押しながら切開して作業は終了します。

    • このとき、ディスプレイ全体にもう一度ツールを通して、接着剤が切断されているか確実に点検することもできます。


    • 開口ツールで作業の大部分は対応できますが、ディスプレイは(完全にはがれておらず)ケースに若干繋がっています。この残りの接着剤を剥がすにはプラスチックカードが必要です。

    • iMacの画面側を上に向けます。

    • iMacの右上隅から、ディスプレイとフレームの間にプラスチックカードを挿入します。

      • 3/8 インチ(9.5 mm)以上挿入しないでください。内部の部品が損傷する可能性があります。

    I actually DESTROYED my display (black vertical strips) by pushing the card in a bit TOO DEEP. So it is REALLY important to insert the card only a bit (1-2mm) more than the cutter wheel, in particular at the top side, where many flat cables connect the panel with the PCB. These can be damaged very easily!

    Peter Fischer - 返信

    Same thing with me…. Pushed cards to far…. new panel needed…€600…..

    i think ifixit needs to place a bigger caveat, as I have missed it the first time

    i successfully upgraded two imacs. one opened with ifixit pizza knife and another with a regular paper knife. however, when i had to open the first one once again i broke its screen glass. it seems ifixit adhesive strips are too strong. next time i’ll try to use heater to weaken glue tension.

    • プラスチックカードをゆっくりとねじって、ディスプレイとフレームの間のスペースを開きます。

    • ゆっくりと移動し、ディスプレイガラスに過度のストレスがかからないように注意してください。約1/4インチ(6mm)の隙間を開けてください。

    My children tend to collect cards like this from hotels, Disneyland, old IDs, iTunes cards, gift cards etc. They came in handy for this step. After wedging in the first card into the left corner, I wedged the left corner, then added cards along the bottom edge. Finally I continued to push in additional cards to existing cards and found that this created a smooth even pressure along the display top. At 2-3 card-thickness the last of the adhesive let go, gentle as a baby.

    • この手順では、iSightカメラの前でスライドを止めてください。破損する恐れがあります。

    • カードをディスプレイの中央に向かってスライドさせ、残っている接着剤を切断します。

    was denn jetzt? Vor der Kamera aufhören, oder in Richtung Bildschirmmitte schieben, um DEN REST zu entfernen? Wenn ich vor der Kamera aufhöre, kann ich nicht alles an Kleber entfernen.

    Julia S. - 返信

    • カードをもう一度コーナーに戻して、接着剤が再付着するのを防ぐためにカードをそこに残しておきます。


    • 左上隅のディスプレイとフレームの間に2枚目のカードを挿入します。


    • 軽くカードをねじって、ディスプレイとフレームの間のスペースを少し広げます。

    • 反対側と同様に、接着剤が剥がれるようにゆっくりと移動させ、ディスプレイガラスに過度の負担がかからないように注意してください。


    • プラスチックカードを中央に向かってスライドさせ、もう一度iSightカメラの直前で止めます。


  3. Fixmasのスピリットを広めましょう
    • カードを左上隅の上部に差し込みます。


    • ディスプレイを5cm程度持ち上げてください。ーまだデータケーブルと電源ケーブルがiMacに接続されたままの状態です。

    • カードがコーナー付近に挿入された状態で、カードをゆっくりとねじってディスプレイとケースの間の隙間を広げます。

    • 固着されたまま剥がれない部分がある場合は、作業を中断してまだ付着している接着剤を切断するためにもう一枚カードを使用してください。

    • ディスプレイの上部をフレームから持ち上げます。

    I would recommend using suction cups at this stage to lift the display.

    Marco De Palma - 返信

    • ディスプレイを片方の手で持ちながら、もう片方でディスプレイの電源コードの接続を抜きます。

      • 接続部に簡単にアクセスできるようにディスプレイを(少し)持ち上げてください。ただし、ケーブルを引っ張ったり、接続部を圧迫しないようご注意ください。(約20cm程度)

    Mark all cable connectors with a spot of white correction fluid before removal. This will remove the risk, when reinserting them later, of getting them the wrong way round. Yes - I know they will only plug in one way round, but it does make life easier if you are not in perfect lighting!

    The display cable, the wider one, has a lock on it , usually a plastic tape lift tab to release it, once thats flipped it should come out fairly easily, if your experiencing resistance and the cable isn’t coming out then check for this lock/latch, the power cable just pulls out, just don’t rush it everything should go fine, fairly easy to do with the end result a working iMac

    There seems to be missing a step or two. As I was removing the old display, there are two wires that need to get transferred to the new replacement display. There is not note about these two wires located at the top of the display. The 1.128-inch ribbon cable and then this other 4-inch long, two-wire cable that goes to a very small circuit board that is 1/4 by 3/8 of an inch and seems to be adhered to the panel.I have not been able to get this cable off the old display. There is a port for it on the replacement display.

    Note: When ordering this screen, and plastic cards as noted tools, ifixit.com did not list the pizza cutter or the new replacement adhesive strips. So now I’m not sure how to get the new one on and secure.

    Todd Derek - 返信

    The adhesive strip along the bottom is designed with a pull tab on each outer end. Rather than lever and pull the screen simply carefully pull the tab which removes that half of the lower adhesive strip and frees up the screen.

    Be extremely careful removing the LCD Temp Sensor from the rear of the screen. If you pull the wire, you run the risk of severing the metal wire from the connector but not notice it because the surrounding plastic insulation may still be intact. Use a razor blade so “shave off” the sensor under the adhesive. I just had the screen replaced by a local shop and, upon boot, the fan was running full-speed and the Mac’s speed was miserable; Excel took 30 bounces in the Dock to launch rather than the expected 4-5. Novabench showed the Mac running at 4% of its expected speed (overall). The tech examined the sensor carefully, found the broken connection, soldered it back into place, and all was fine. Note that the (partially disconnected) sensor actually showed up when I ran Macs Fan Control in an attempt to work-around this. No problem controlling the fan speed then but the iMac’s running speed was awful until the disconnected sensor wire was fixed.

    hey Simon, I used 2-sided tape….this is assuming the new sensor doesn’t already come with an adhesive surface already applied.

    a roll of kapton tape for your own peace of mind will make sure nothing detaches from thermally-induced adhesive crystallization

    Two notes here:  If you are using OWC’s Thermal Sensor HDD Upgrade Cable, be sure to tuck the cable under the hard drive slightly.  You cannot allow the connector to sit near the top edge since this will not allow the monitor to sit flush with the chassis when it is reattached.  Additionally, the SATA connector does not seem to fit together as snuggly as when it was connect to the HDD, so tape or a plastic cable tie to keep the connection tight may be good insurance to prevent it from coming loose.

    If you are planning on dual booting with Windows 10, the Windows 10 installed failed when the SSD and HDD were both connected at the same time.  I had to disconnect the HDD until Windows 10 was installed.  Note: I did a fresh install on a new SSD not configured as a fusion drive.  If you are planning on doing this as well, use packing tape (or something similar) to hold the monitor in place until after installing the OSs.  Then reconnect the HDD and apply the adhesive to the monitor for a permanent seal.  Good Luck!

    Gregorio Alvarado Sahli -

    Full removal of the speaker is unnecessary - just very carefully unplug the two-conductor power button cable, which is routed through the groove along the edge of the speaker enclosure. Next, unfasten the two large torx screws holding the speaker enclosure to the chassis. Now you can easily scoot the speaker away from the drive mount - move it over just enough to reach the drive mount’s 2 torx fasteners beneath the edge of the speaker (a CM or two). There’s now enough room to easily remove and replace the drive assembly .

My experience in upgrading this unit to a Seagate 4TB hybrid ST4000DX001 went fine except for the fans running at a constant higher RPM. Using Macs Fan Control is solving my issue for now. As a tip, you do not need to remove the left speaker, you can loosen the two screws and angle it leaning to the left.

MFR2VCB - 返信

What setting do you change in Macs Fan Control? Im looking at getting a SSD fitted to my Late 2013 iMac by a certified repair centre who have said they will do it for me if I provide the SSD but they did mention that the fans would most likely speed up as there won't be a temp sensor in the SSD. Thanks.

Lewis: simply running the Macs Fan Control app will do it. Otherwise the fans run at full speed because they have no temperature measurement.

To solve the fan issue I believe you need to add a temperature sensor like this: http://eshop.macsales.com/item/OWC/DIYIM... OWC told me if you don't, your fans will go crazy because the new drive probably does not this sensor like the original mac. Just heard it today and then read this. Hope this helps!

Thank you this fixed the fan issue for me!!

Hi, is a temperature sensor (like the one linked above) necessary if I am replacing the hard drive with an SSD? Also, what is recommended for the SSD "cradle" since this model iMac comes with a 3.5" disk and SSDs are 2.5"?

If I replace a Fusion Drive with an ordinary drive, will there be issues? Or is the fusion SSD a separate part and will be integrated when the new drive is formatted?

Alan Browne - 返信

Fusion SSD is seperate.

I haven't had any fan noise issues at all after installing an Samsung 840 ssd instead of the seagate hdd.

Hi - I replaced the Hard Drive using this guide. But it looks like my imac no longer boots up through the fusion drive. How can I confirm this or fix it to boot back through the fusion drive?

You will have to fuse them back together through Terminal.

I have put 1st a 500gb and after a 1tb ssd both Samsung evo 850. I didn't needed to use the OWC in line thermal sensor, I even have bought it but first upgrade it hadn't arrived yet and I wanted to know if I would really need it since I have read somewhere that the latest versions do not need it anymore. my imac is a late 2015 and I am not sure if really is the fact of it be a newer version or if the Samsung evo 850 have some thermal sensor inside. by pass, the ifixit adhesive and the included apener are both great. it was very easy to replace the hard drive, however replace the processor as a little bit hard but I had success in doing it

Is it possible to change the power button on the late 2012 iMac 27"? The cable got cut from the speaker but I was able to MacGuyver it with another power button. It looks like you'd have to take the metal bezel off which would have to be cut... Anyone have any ideas or suggestions?

Can I have one SSD for system and another HDD for media in IMac Late 2013 (thin body) , like IMac 2011(fattest body)??

Good guide. Would be even better if you added tips regarding replacing the adhesives on the display once the repair is complete. Thanks!

To reassemble your device, follow these instructions in reverse and use our Adhesive Strips Guide to reattach the display glass.

That guide exists and is the first option in the EMC 2546 guides list: iMac Intel 27" EMC 2546 Adhesive Strips Replacement

I did the installation of a new hard drive following the ifixit guide, afterwards I had the fan issue, I did not have the fans spinning at full speed like some people have been describing but the CPU and other components would just get hot very fast, this seemed very strange, installing Mac fan control didn't help much, as the CPU and stuff would heat up, and if I did not want to damage my computer I had to crank up the fans. I was desperate for a solution, so I purchased the kit from OWC (after reading "weddings" comment) being a bit sceptical, because I wasn't sure if installing a sensor would stop the CPU from heating up. But after the Installation everything is back to normal. The CPU stays at around 40 degrees, and the fan stays quite. I don't understand how this works, but I definitely recommend installing this sensor if you have similar issues after upgrading your hard drive, even if it means opening your iMac again ;). For the record: I have an iMac 27-inch Late 2012.

The guide made it extremely easy to perform an SSD swap. The wheel was the perfect tool, and the strips were perfect for the job.

I made the change of the hard disk and when closing the imac one part of the screen was left in black that could be this?

I got this Screen problem when replaced the HDD with OWC SSD in my iMac late 2012 model.

Can anyone help me to solve this problem ? PLEASE ! I REALLY WORRY ABOUT THIS.

Please take out the photo down here.

Thank you so much !

I have the same problem as you, change the hard drive and now I have a part of the screen in black

john sayegh -

Check and make sure that the Display Data cable is properly seated when attaching it in Step 19.

Philip Sedlmair -

Completed this guide no problem at all. Previously replaced the disk on a smaller iMac without incident.

Images are excellent, detailed and specific.

No issues with CPU fan as mentioned in some other comments. iMac 27inch Late 2012 model.

Thank you for this guide: very clear and detailed. The dedicated adhesive-cutting tool was well worth the money, as it sped up the cutting and reduced my stress level! I did need to repeat steps 9-16 a few times before the screen felt loose enough to lift away from the body. TAKE YOUR TIME - the screen WILL lift off without much force when it’s ready.

While the case is open, allow a few minutes more to remove the left speaker and carefully remove any dust and fluff that has been sucked into the case by the cooling fan!

I opted for a 2 TB FireCuda drive. Booting up and loading of apps is noticeably faster, for only a few pounds more than a 2 TB traditional HD: a cost-effective solution for an older Mac.

I think they should change “Difficulty” levels. With this guide: “Easy”; Without this guide: “Difficult”. Thanks again iFixit for another successful repair.

Hi Guys, im planning to change my hard drive to SSD according to this instructions, just a simpel question before i get started; How do you do with the system and everything that is installed on the old drive, are you just cloning the disk before change or what is the procedure? (and if so, what tool do i use for that?)

Best regards, have fun :)

Yep, you got it! Grab an external hard drive enclosure and clone your old disk to the new disk before you install it. Instructions are here. Good luck!

Jeff Suovanen -

Worked well but in deed it is not that easy. All important steps are explained and with the kit I’ve got everything I needed. Quotation from one Apple Reseller here was 730€ für 1TB SSD, so I was able to save quite some money. Thanks! Best regards from Bavaria

Hi all. I have a 27” iMac (2013) but it was configured with the BTO 500gb Flash/SSD blade on purchase, so didn’t come with a HDD fitted. I want to add one (either a high volume spinny disk or another SSD, I can’t decide yet!), but I’m wondering what parts I’d need. I couldn’t imagine that Apple would include the driving mounting parts or SATA and power cables for a machine that was ordered without an HDD. Has anyone cracked one of these SSD only iMacs open to see what’s what?
