The El Capitan thread (OS X 10.11)

[Amethyst1]

I had a look at the system requirements for the DosDude patchers and even the one for High Sierra doesn't support the 2006 iMac.

Late 2006 iMacs are stuck with El Capitan no matter what due to non-SSE4 CPUs. Missing graphics drivers once going past patched Mavericks is a huge additional issue even if one gets El Capitan to run though.

Hi, I happened to see this article, and I own an iMac 20' (2006 late) A1207. I wonder whether my iMac is able to be upgraded to OSX El Capitan? I already made a USB boot device, but when I choose to boot with the USB the iMac stays on Apple logo screen.

At the minimum, you need to use a patched boot.efi on your USB drive to boot the El Capitan installer. Additional patches are then required to get USB working for keyboard and mouse input IIRC, and you'll still be stuck without graphics acceleration.

As far as i’m aware the furthest you could go is a patched 10.8 install on that machine.

Mavericks.


FWIW, I got Yosemite running on a late 2006 MacBook Pro by replacing boot.efi and editing PlatformSupport.plist. USB works without further ado but lack of graphics acceleration is kinda… brutal.

edit: I realised the first sentence was potentially misleading/unclear and (hopefully) made it clearer.

Oh my gosh, Mavericks eh? I had no idea. Definitely going to try that. Thanks for the link!

Thank you so much! I installed the OS X Mountain Lion as the tutorial you provided. It's fine to use iTunes now even though I still cannot log in the app store, but it is better than OS X Lion for me to use!
