Hi everyone,


I have made a hackintosh using iAtkos Ml2 and i have a Sapphire HD 7950 graphics card running ML 10.8.3. My problem lies when booting up, i just get a white screenwhen booted using the flags fx_kernel arch=x32_64 GraphicsEnabler=Yes AtiConfig=deadbeef -f -v.


Please note that i have done some reasearch myself to attempt to resolve the issue. Although it appears that i am in the worst possible situation as i don't have a secondary/build in graphics card and my computer can't sleep which are the two main fixes for the problem. I am aware that there is a fix by using fbrotate at startupalthough it doesn't appear to work for me  :(.


If anyone has a suggestion for fixing the issue please make a post!


Many thanks,
