Breaking News for AMD cards!
AMD Graphics Cards wake to black screen has been solved and is now in the latest version of clover 4296. Its an SSDT fix that was discovered by Mieze and Slice incorporated it into Clover.
What does this new clover do? It replaces the need for the lilukext and whatevergreenkext fix for AMD cards for use as primary display. In other words, the black screen and black screen after wake for AMD Radeon cards since El Capitan is fixed/solved. Most older and newer up to Polaris cards are able to use the card as a dedicated graphics card without the need for an IGPU or integrated graphics.
This means that AMD cards are that much closer to running "native" in OS X El Capitan through High Sierra betas. Audio and frame buffer for multi display outputs still need fixes in some cases but the annoying black screen issue is fixed. This will make it much simpler to install and run AMD graphics cards on a wider variety of platforms.
Update: This works for UEFI boot systems, there seem to be some bugs for some users with older motherboards that use legacy boot mode only, so whatever green and lilu may still be needed for those users. This new clover should work for Haswell and newer systems so its still a great plus.
