Lenovo Thinkpad t520 i7-2760QM 1920x1080 Mountain Lion 10.8
Finally I managed to get my pc working on Mountain Lion 10.8 and would like to share DSDT files. These DSDT files includes high resolution fix and sound fix.
There are few issues I don't know how to solve and would like to ask for help from more advanced users.
1. I can't get it boot without external USB drive.
2. I don't know where to get wireless drivers for this machine
I would be much appreciated if someone could help me to solve these issues.
Thank you in advance for any comments and useful info.
Fixed booting without external USB issue. I copied '/Extra/Extensions' directory from Unibeast external USB drive to '/Extra/' directory on drive where OSX is installed.

Processor Name: Intel(R) Core(TM) i7-2760QM CPU @ 2.40GHz
