We don’t have a Mac to test this, so if you run into problems, the best place to troubleshoot is probably the thread of the relevant original forums at.
Finally, we just don’t know until Apple has finalized OS X 10.8. Maybe even with an easy USB installer? Who knows, but it’s also possible that Apple will bring support for these Macs in the last OS X Mountain Lion building, and it’s as possible as the following developer preview structure to remove the ability of the above method to work at all. The whole process is pretty similar to getting Hackintosh running on supported Mac hardware, and assuming Apple doesn’t change anything, it could theoretically be possible to create custom third-party OS X 10.8 installers on the road specifically for supported Macs. Kextcache -k / Volumes / ~ MLPartitionName / System / Library / ExtensionsġWorking in an unsupported Mountain Lion system. Rm -rf /Volumes/~MLPartitionName/System/Library/Extensions.mkext If so, restart it.ġStart in single user mode (Command + S) and type the following:Ĭhmod -R 755 / Volumes / ~ MLPartitionName / System / Library / Extensions / AppleIntelGMA950.kextĬhown -R head: wheel /Volumes/~MLPartitionName/System/Library/Extensions/AppleIntelGMA950.kext Return to the white MB file, install kext using KextHelper, and restart it.ġAfter booting, you should be able to see a pop-up window saying that kext is not compatible. On an ATI graphics card I don’t have a Mac to test them, I think it’s the same, try ATIRadeonX1000.kext, ATIRadeonX1000GL.bundle, ATIRadeonX1000VA.bundle, ATI-yliadxos.bundle and report back. Try using the method above depending on what video card you have and report the results! Thank you! There are 2 ways to complete this step: a) Copy and install the correct kext manually. (For MacPro1.1 and 2.1 with an updated graphics card, you should get a fully functional ML) If you did everything right, you should be able to access the desktop, but you don’t have any accelerated graphics, just a frame buffer. Launch it now with MacBook White and make sure the ML starts. This step is important when the EFI reads this in sequence.Īdd this line for MacBook 07 and 08 just above MacBook6.1įor Mac Pro 06 and 07, add this line directly above MacPro4.1: 06: MacPro1,1For 07: MacPro2.1 If you try to delete the Plist file, the Kernal Panic will greet you during startup.īe sure to add the ist template tag, if you’re using a MacBook White like me, add MacBook2.1 just above MacBook6. Add the unique ID you just copied to ML 10.8 to the ist file. U Now go to “/ System / Library / CoreServices” in the Mountain Lion section. Remove the hard drive from MacBook White and reinsert it on a compatible Mac and restart it in Mountain Lion.
Cause: Mac-F4208EC8” “Mac-F4208EC8” is your unique ID for your Mac, so copy it down. It should say “Incompatible Mac detected. Restart MB White and hold down “CMD + V”. Remove the hard drive from a compatible Mac and insert it into your MacBook White. I don’t have FireWire for target disk space, so I removed the hard drive from my MacBook White, dropped it on an ML-compatible Mac, and installed Mountain Lion normally.Įnable everything until you get to the desktop
