Hi I installed osx yosemite on pc everything worked perfectly installed drivers and kexts etc. However my fans on my gpu do not work I have tried changing them in the bios and they do not change speed.
They do not move. However in my windows partition they work. My system specs are i3-4130 motherboard GA-Z87Z-OC-FORCE and a r9 290x.
I've gotten most of my setup to work, but my R9 290X won't give me full resolution on my Ultrawide 21:9 display... I'm connected using HDMI and it gives me 1920x1080 which is not the full 2560x1080 my display can take. I fiddled with System Preferences and even SwitchResX and can't get it to work. I also noticed that HDMI audio doesn't work either. What can I do?
