Hey everybody,
I'm another person stuck at the graphics and sound problem and I can't figure out how to fix the problem. I'm on a 2006 MacBook Pro (A1211), ATI X1600 graphics. I'm running a fresh copy of 10.10.5 from Lion. I've been searching through the post but I can't figure out how to get the Yosemite to see the full 128MB of graphics instead of 5MB, as well as how to get sound. I tried using the Kext Utility, and can't figure out what kext files I'm supposed to put into it, or where I'm supposed to get them, though I do understand how to use the Kext Utility. I've been to Post 458 mentioned in the description for the graphics, but it didn't work.
I tried the latest Extractor from OS X Hackers, and during the install, the checkbox for Yosemite is greyed out and I can't select it. I can only select the basic install and the Open GL beta. If I continue with the install, it installs the software and the folder with all the utilities, and at the end of the install, Safari opens with a dead link from a tmp folder. Also, some of the links are dead, and the YosemitePatchFiles.zip is corrupted for me. I don't know if I'm even supposed to be using Extractor or not.
What am I doing wrong and is getting my graphics and sound set up possible? I feel like I'm so close to getting this but can't seem to figure out these issues!
Edit 1: I got display working! I didn't know that the 'sudo nvram boot-args="kext-dev-mode=1"' code was supposed to be done via CMD-S at boot, I was putting it in terminal. Display is great! Now for audio...
Edit 2: Found different directions I missed when going through the thread. After rebooting from the display kexts from Edit 1, I used the audio kext found in an earlier post with Kext Utility, installed the kext, restarted normally and now I have audio too!
Edit 3: I saw that it was a bad idea, tried it anyway, and installed updates from App Store. This broke display kexts making them unrepairable, and I have to re-install Yosemite as I'm back to 5MB of graphics and no sound. At least I know how to get everything to work this time lol.
Edit 4: When I'm installing, I make two partitions. A small one for a fresh-from-DVD 10.6.0 update, which I update to 10.6.8, then to 10.7 to handle MacPostFactor. The other, larger partition is for Yosemite. Right after Edit 3, I reinstalled 10.6.0, updated to 10.6.8 and had an error. It restarted, re-downloaded, restarted, and I was stuck with a blue desktop screen and an unusable OS. Until this morning, I'd have an occasional kernel panic during the MacPostFactor setup, but now my 10.6 disc install is failing every time now. I don't know why it's happening, so I've actually gone back to 10.4 to at least try and get a usable OS to update. The DVD is in good condition and the SSD is a week old.
Edit 5: After almost six hours of install issues for something that should theoretically take 1h 45m, I got back to 10.10 but now the kexts install isn't working (5MB and no sound). I got a bootable 10.7 disc so that will save time in the future if I have to start from scratch again. For now, at least I can re-install 10.10 as a clean install for 30 minutes instead of going back to the beginning again.
Edit 6: Finally back to a normal, functioning 10.10.
