Yosemite on T61 and T61P development
Posted: Tue Nov 04, 2014 12:22 am
I'm opening this discussion for development of Yosemite (Mac OS 10.10) on Thinkpad T61 and T61P. This is a continuation from http://forum.thinkpads.com/viewtopic.ph ... 35#p743735.
This is my latest kit (download link is fixed 3/31/15)... http://s000.tinyupload.com/?file_id=053 ... 1987307154
The install is done with the chameleon installer by Chris1111... http://www.insanelymac.com/forum/topic/ ... -r2456-v2/
The latest version of Chameleon is available here... http://www.insanelymac.com/forum/files/ ... on-23-svn/
UPDATE 4/25/15:
I'm investigating whether 10.10.3 can fix some issues.
So far, it's a fairly stable build,with some minor issues that are similar to those introduced with 10.9.2 (inconsistent sleep, graphics speed stops toggling after display sleep, etc.)
Quick instructions:
NOTE: I have changed some instructions...
Create a "USB installer" using the application by chris111 (follow his instructions).
Replace the "Extra" folder on the "USB installer" you created, with the one in my kit. Fix the cache's using Kext Wizard.
Use that "USB Installer" to install Yosemite onto your hard drive. Again, replace the Extra. MOVE ALL the kexts from "/Extra/Extensions/" to "/System/Library/Extensions/". You can replace whatever kexts are already there, or back them up somewhere else first if you want.
Run the app "Kext Utility".
Hopefully, you should be able to boot Yosemite. Good luck.
(note: USB flash thumb drives might not boot on your T61, it didn't on mine. As an alternative, you can create your "usb installer" onto an external USB Hard Drive. Or, you can make an extra partition on your internal hard drive to use as an installer.)
Thanks to chris1111, Madara-san, jzhang18, Rehabman, Bronxteck, bugmn, manuelthink, chameleon team, and everyone else who helped or will help. Please continue to contribute improvements here.
Thanks!
Peace.
