Hey guys, I'm trying to get dual DVI working on my Sapphire 4870, in Mavericks DP1. (It should be roughly the same as ML)
I've tried various kexts available through this thread, but all to no avail.
Specifically, the ATIFramebuffer.kext on the first post will make my screen display gibberish black and white after the Apple logo during bootup (computer still runs fine, I can hear the volume adjustments)
As for the exotic QE/CI patch, I get kext load errors when booting in verbose.
Is there any manual editing of the kexts I need to do to get dual DVI to work? If so, will anyone kindly point in the right direction? Thanks!
