R7 250 (OC 2GB) - No kext loaded

[Erwin Weber]

Hi! 

 

I succesfuly installed Niresh Mavericks 10.9. Everything is working except the video card. I have a R7 250 OC with 2gb (the usual r7 250 has 1gb), i found a kext for 10.9 (http://www.hackintos...lastest-driver/), installed it with kextwizard and than repaired permission and cache s/l/e. I booted with GraphicsEnabler=No and than with Yes and ... nothing. I've also looked at the package contents and checked the Device ID and it is as it should be. 

First time I installed Mavericks: everything was functional, but somehow i lost "System Reserved". I reinstalled windows 8.1 and than mavericks again. Since then, no matter how i reinstall mavericks or how i install or modify the kext, mac refuses to load the video card properly.
