EraseR72 Posted March 16, 2013 Author Share Posted March 16, 2013 Yes i did that... and Lion wont boot just block. Now only works GraphicsEnabler=No with no kext loaded only 3mb on 1024x768 resolution. Any good kext or fix for Ati mobility 4550 ID 1002 9555? What bootloader to use and what kext use full resolution 1600x900 on lion 10.7.2? Link to comment Share on other sites More sharing options...
