boila Posted August 13, 2015 Share Posted August 13, 2015 Hi All, Recently installed OS X Yosemite 10.10.4 and I have almost everything working apart from the graphics and audio but I'm sure the audio won't be an issue. I have a MSI R9 270 (non x) and I've tried numerous ways to get the card working and I've come to a dead end. I've attached my ioreg (wouldn't let me attach the non zipped version). Any idea how I can get this card working as it's the last hurdle to using OS X. Please please please help. Thanks. If you need more information let me know. ioreg.zip Link to comment Share on other sites More sharing options...
