themacmeister Posted March 18, 2015 Share Posted March 18, 2015 I attempted this install with 10.9.5 using "Gliff" framebuffer, and ATIPorts=2 or 3. Patched info.plist in AtiRadeonX2000.kext and AMD4600Controller.kext with matching vendor/device IDs. Works the same with either GE=Yes or No. Connected via DVI. Desktop and all software seems to run perfectly, but the moment I try to do any OpenGL benchmark, the screen blacks out (locks up). I understood that I might need to downgrade to 10.9.4 OpenGL.Framework ??!! or earlier??? Any thoughts or guidance would be appreciated. This card is way better (I think) than my Quadro 370fx currently installed. So very very close... PS. I guess I can find older OpenGL.Framework's in older updaters (Combo).
