    [GUIDE] Thinkpad T420 with (Mountain) Lion

    Hi all, Thanks for a great thread! You guys are awesome. I've created a unibeas installer with ML 10.8.2. On the USB I swapped out the OSInstall and OSInstall.mkpg. (I didn't follow steps 1-4, and 6 cuz I don't understand them ) The boot off of the USB displays the apple logo, then just gives me a blank screen. Do you guys have any suggestions? Should I downgrade my BIOS to 1.33? Its at 1.36. link to photo of screen after using -v flag GraphicsEnabler = no also resulted in a blank screen https://mail-attachm...JitdInx_r-ia6K8
