VirusX Posted March 28, 2015 Share Posted March 28, 2015 when you say black screen, does the monitor go into stand by or is the monitor on and just black? have you tried to unplug and replug the monitor while you are booted into yosemite? does dvi work without hdmi plugged in? you might get hdmi sound to work with toleda's patch here in the forum...

marceljj Posted April 4, 2015 Share Posted April 4, 2015 Press Windows key + alt + f12 for a few seconds, until your monitor turns off. Wait until your computer enters sleep mode, and then wake your computer. you screen should work. unfortunately you'll have to do this every boot unless you patch your graphics kext, which is very difficult.

santinobch Posted February 18, 2017 Share Posted February 18, 2017 Hey did you ever make this thing work? I have the same card, and i have read that it may work if you load a vbios of another card sorry for bad english ༼ つ ◕_◕ ༽つ https://www.tonymacx86.com/threads/radeon-compatibility-guide-ati-amd-graphics-cards.171291/ Note on XFX cards:Many people are reporting problems with XFX cards, especially HD 7xxx / R9 generation. They're using a custom BIOS which can cause a crash upon booting, which can't be fixed in OS X.A common solution is either flashing a alternate VBIOS on your card (only do if you can recover form a bad flash!) or using Clover to load a compatible VBIOS dynamically (without flashing).
