FFForever Posted November 18, 2015 Share Posted November 18, 2015 Hey hey, I was able to get my r9 270 working with all 3 monitors (1x DP, HDMI, DVI) via injecting my dev id into the Radeon7000 and AMDRadeonX400 (under Pitcairn) kexts. The only issue I have is when waking from sleep. After the system starts up again all 3 monitors stay black with the power lights on. Link to comment Share on other sites More sharing options...

FFForever Posted April 27, 2017 Author Share Posted April 27, 2017 (edited) Apologies in advance if I should have opened a new thread instead of reviving an old one. Has there been any advancements in getting AMD GPU's to wake from sleep on systems running 10.11/10.12? Based on that thread it seems there might be some leads if you used the intel integrated gpu as a helper card. Someone on IRC mentioned that should only be required if you don't get the graphics to initiate during boot. Looks like there also might be success with patching the cards firmware (something I'd prefer to avoid). Edit: My current setup is: * OS X: 10.12 * ATI Injection: True * Framebuffer: Futomaki * Connector patch: No longer required * FakeID: 0x68001002 Edited April 27, 2017 by FFForever Link to comment Share on other sites More sharing options...
