Sapphire Radeon HD 6450 on El Capitan
I am running El Capitan 10.11.6 on my system for a week now and everything works fine (even iMessage, FaceTime, iCloud :D).
The only problem is that the OS won't get the right framebuffer for my graphics card. Instead, it's using the default RadeonFramebuffer. QE/CI works though, but I can't play DVDs through the DVD Player app, because then it crashes. I am able to play DVDs through VLC, so it's not a big deal but it annoys me that everything works fine, except that damn framebuffer
I've tried putting my Graphicscard's rom in the /Extra Folder with 'Use Ati Rom' enabled, GraphicsEnabler=yes, AtiConfig=Lotus/Muskgrass/Bulrushes, I've tried VGA as well as DVI but it uses RadeonFramebuffer nevertheless:
Ricos-iMac:~ rico$ ioreg | grep ATY
| | | | +-o ATY,AMD,RadeonFramebuffer@0 <class AtiFbStub, id 0x1000002d3, registered, matched, active, busy 0 (2725 ms), retain 8>
| | | | +-o ATY,AMD,RadeonFramebuffer@1 <class AtiFbStub, id 0x1000002d4, registered, matched, active, busy 0 (1 ms), retain 8>
| | | | +-o ATY,AMD,RadeonFramebuffer@2 <class AtiFbStub, id 0x1000002d5, registered, matched, active, busy 0 (1 ms), retain 8>
My device ID (vendor = 1002, device id = 6779) is in AMDRadeon6000.kext, as well as in AMDRadeonX3000.kext and both are loaded.
I'm out of ideas. Anyone that could help me with it?
Thanks in advance.
