Changing Kext Hd 7750
0

Question

Please, can you help me?

 

I just installed Mac Os X 10.8.5. According some information this version of the OS is full compatible with Radeon HD 7750. After the installation I rebooted my computer and after the Apple´s logo the screen keeps in black color. The system isn´t stopped because if I press some keys I listen through the speakers a  "How to use tutorial". I downloaded the kext for my graphics but I don´t know how to replace it. Please I need some help for that.

 

Thanks in advance for your incredible help.

Boot with -x . It will load safe mode and replace kext in that using kext wizard or utility.
