2007 iMac CPU Upgrade

I’m planing to upgrade my CPU in my mid 2007 iMac since it’s socketed. So would a Core 2 Duo T9400 work with my Mac?

Looks like it can be upgraded: see http://dosdude1.com/highsierra/ This excellent software allows later versions of OSX on ‘unsupported’ Macs.

He comments: “The 2007 iMac 7,1 is compatible if the CPU is upgraded to a Penryn-based Core 2 Duo, such as a T9300”

Just did this upgrade last week (July 2021). Worked a treat in my iMac7,1 2007. Successfully ran both Mojave at 10.14.6 and Catalina 10.15.7. About This Mac doesn’t show the correct speed, displays 400Mhz <grin>. Clips along nicely, everything works just fine, Bluetooth, Wifi. Thought I would smarten it up too with a new paint job, so it didn’t look so dated.

Hello @ronan0s

Sorry for the delay in replying

I used PlastiKote Metallic Blue for the paint. I disassembled the iMac including removing the stand, so that I could make a proper job of spraying it.

I realised that the tiny microphone hole matrix at the top of the display would get clogged by the paint, so after removing the microphone I replaced those tiny holes by drilling a single hole about 2mm diameter.

I wanted to spray the black iMac logo independently so with the help of isopropyl alcohol I managed to remove that and sprayed it matt white.

For the keyboard I popped off all of the key caps, and put tape in their place to protect them from the paint. With the mouse, I masked off the aluminium body pretty easily using the gap between plastic and metal.

I decided not to spray the memory door, as it was already going to be a tight fit to replace after getting a bit of overspray.

Now I just need to decide what colour to use for the next one :-)

Finding a T9300 is getting hard these days, in any case here's the guide to replace is iMac Intel 20" EMC 2133 and 2210 CPU Replacement

@paddymacman - Looks good! I had to take a double take as I could have sworn that was the new 24" M1 iMac!

Still... Be careful as the limited RAM this series supports does limit you on what apps can run (or run multiples).

Woah How'd you get your mac to be Blue, Paint anodized? Did the T9300 Swap like 2 years ago and got a 2010 wifi card still working great.
