Apple does not include 64-bit graphics drivers for some models.
Here are the Intel GMA X3100 64-bit kexts to use with 64-bit kernel
and a install script for:
MacBook3,1
MacBook4,1
MacBook4,2
MacBookAir1,1

I’ve been doing everything from an external USB boot drive. (2.5 drive in a case…) And using a USB image of the os10.8. You do have to run the cmd-v from a cold boot to get the originating code. you have to have the OS installed first- and you can’t modify it from the USB install… I’m currently having problems with adding the codes in… i keep typing them in wrong.

Anyone got an idea how to get that Mac-F*** code from a running system?
I don’t have a mountain lion compatible mac atm, but if you extract the install.dmg to a flashdrive, why shouldn’t you be able to manipulate the PlatformSupport.plist in advance?
My other Idea would be if one of you could install ML on a compatible mac and upload an Image? pretty sure that I could do the rest myself, gonna keep my Lion sys anyway so I could use it to edit the ML installation.

Anyway, I would really appreciate any help or other ideas, meanwhile I’ll start looking for a MacBook to borrow for a day..:D

ok, “ADDING” the Mac-F****** code in the SupportedBoardIds and MacBook2,1 in the model list is easy with the xCode plist editor tool… and gets the system pass the support test. You need the modified boot.efi to get the system to accept your 32bit efi and boot (note this limits you to 4 Gigs of ram… I have a laptop with 4Gigs I don’t care) But where in the universe can you find the 64 bit drivers needed to make the IntelGMA950 work? The release of ML has no 32 bit support… Some of the DP’s did have some 32bit support… So using old drivers with 10.8 GM doesn’t help…. Any clues? Thanks!

F-22788A9
MacBook4,1

Tried putting those in and I get a momentary “do not enter” sign on-screen then it just boots to another HD (that’s running Snow Leo). I was able to get Lion running without any hack.

Suggestions are welcome.

i don’t understand this:

7. In PlatformSupport.plist, remember to add your model identifier, if you are using a MacBook White like me, add MacBook2,1 right above MacBook6,1. This step is important as the EFI reads this by sequence.

For MacBook 07 and 08 add this line right above MacBook6,1

For 07: MacBook2,1

in my PlatformSupport.plist* i’m missing macbook 6.1 were i should put the line macbook2,1 above

plz help me – thx

*looks like this:

Absolutely Correct. It’s Apple’s way of purposefully obsoleting perfectly fine computers in a attempt to collect more money from you on a already severely overpriced product. Must be a way to recoup the monetary losses on their joke of a OS Lion.

I have Windows 7 and Kubuntu 12.04 LTS on a Pentium 4 3.0Ghz with a Radeon 9600XT from 2003. I threw in 2 gigs of ram and it works beautifully for everything I want to do with it. I run the latest version of Firefox, iTunes, and other apps. There should be no reason that I could not run 10.8 on My Core2 MacBook with a GMA950 with the horsepower of the Core2, as long as I’m not gaming. I turn off a lot of the eye candy anyway on my newer machines, so that option should be available for users of older Mac hardware, or have it auto adjust.
