Jacharcus Posted December 27, 2014 Share Posted December 27, 2014 Hello! Does anyone know if R9 285 or R9 280 work OOB in Yosemite?I know for sure that R9 280X does,but I'm not sure about these two cards..I haven't found many topics in which they are mentioned, and I want to be sure that HDMI and DVI work OOB..has anyone tested them?I don't want to buy a graphics card and then have to return it and buy another one..

vusun123 Posted December 30, 2014 Share Posted December 30, 2014 If not OOB, patch kexts to make them works. That's how AMD GPU plays with OS X. R9 280 works but requires kext editing. R9 285 might also works Link to comment https://www.insanelymac.com/forum/topic/303603-r9-285-or-r9-280not-280x-yosemite-10101/#findComment-2098893 Share on other sites More sharing options...
Slice Posted December 31, 2014 Share Posted December 31, 2014 R9 280 should work OOB. Its deviceID is native for OSX drivers. Link to comment https://www.insanelymac.com/forum/topic/303603-r9-285-or-r9-280not-280x-yosemite-10101/#findComment-2099188 Share on other sites More sharing options...
Jacharcus Posted December 31, 2014 Author Share Posted December 31, 2014 Thanks!Do HDMI or DVI ports work on the R9 280?I want to buy the Sapphire Radeon R9 280 Dual-X OC WITH BOOST 3GB DDR5 384-bit..did anyone test this variant on OSX?I heard that R9 280 is identical to HD 7950..If so can I flash the HD 7950 Mac Edition BIOS to this card?

Slice Posted December 31, 2014 Share Posted December 31, 2014 Do not flash BIOS from different hardware. The Bios reflects where are connectors but it doesn't set them. After flashing you'll get a brick.
