    Lenovo Thinkpad t520 i7-2760QM 1920x1080 Mountain Lion 10.8


    Hi Guys,

    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.

    Hi locale,

    good to hear that you were able to get 10.8 on your machine too! Good stuff.

    On my machine works pretty much the same as are working on yours except maybe bluetooth.
    Also I managed to get working on my machine:
    -sleep
    - battery status
    - dual screen via Digital Port using nvidia graphic card.

    I don't know how about yours, but my machine doesn't work as smooth as I expected. It often freezes for few seconds when opening applications or when you want to close some. Are you facing similar issues or your machine works fine?
