Saf Posted February 15, 2016 Share Posted February 15, 2016 Anyone know how to get this card working on Yosemite? Any kexts? I've had to remove the stock AMD kexts because it just boots to black screen and restarts within seconds with it Thanks, Saf Link to comment Share on other sites More sharing options...

Saf Posted February 26, 2016 Author Share Posted February 26, 2016 Hi, Thanks for the info. My issue is that the device ID for the card is already present in the kexts. When trying to boot the Yosemite installer, get through the verbose mode and as soon as it's about to load the graphical interface, it goes to black screen/no signal. When I set PCIRootUID=1 it restarts as soon as verbose mode is over. Without it, it just stays on black screen/no signal. To boot the installer, I have to remove the AMD kexts from the installer USB S/L/E. That gets the graphical installer to load. Then once the install is complete, I have to boot back into the installer and remove the AMD kexts from the S/L/E on the installed Hard Drive to get it to boot Was told that HD6450 would work OTB and have read a lot of people having success with that card. Not sure what I'm doing wrong. Using this card: http://www.amazon.co.uk/gp/product/B004WYV8Z6/ Hmmm, any advice? I get the feeling there's something simple that I'm doing wrong...
