chaoyuim Posted February 11, 2015 Share Posted February 11, 2015 For those who are troubling with XFX r9 280 (non x) can't entering Yosemite or boot loop. here is your "risky" solution. Voor woorden. Right b4 i thinking about giving up, something crossed my mind. Why not flash the bios. Since i kw R9 280 is rebranded hd7950 and i know HD7950 oob. So, I was set to looking for tutorial about Flashing ATI bios and at the meantime looking for a suitable Bios. After everything is settled. I started to flash the bios. 1. Atiwinflash (is what you must have) 2, check youtube (search How to flash ATI bios ) for tutorial on flashing bios 3, back up your current bios by GPU-z or Atiwinflash 4. download HD7950 XFX" http://www.techpowerup.com/vgabios/" 5. flash the bios , reboot your pc. 6. now, if you have installed yosemite, you should be able to enter mac os x . Be aware there are risks flashing Video card bios. including damage your video card make it useless . Don't intend doing it if you don't wanna take risks. And i won't take any 'credits' from your behaviour. Quote Link to comment Share on other sites More sharing options...
mathq Posted February 17, 2015 Share Posted February 17, 2015 No need to flash the VBIOS, you can tell Clover to use a custom one on boot up. Quote Link to comment Share on other sites More sharing options...
