Hello guys,
I just bought a ATI Radeon HD 7970 and my mac os x is not booting anymore while my windows seven is still working great.
This is what I get instead of the chimera booting screen (attached file)
If I plug back my old ATI Radeon HD 5850, I can boot no problem.
Should I wait for a new Chimera or something ? Any other fix ?
Thank you guys
