Not quite the case with RX580.On macOS 10.13.4:
My Vega 56 has DisplayPort audio working and HEVC working. I am using iMacPro1,1 system definition. Playing the Sony camp video, Quicktime uses about 10.5-11% CPU.
- no RadeonDeInit
- no WhateverGreen.kext
- no Inject ATI
- no graphics SSDT
- no graphics Clover patches
Without AddHDMI DSDT fix (or SSDT injection), DP/HDMI audio does not work.
Without SSDT injection the framebuffer is generic Radeon frame buffer (which is OK) but number of ports is 6 not 5. On my Nitro+ I'm lucky the port types match (almost) they work - that will not be the case with all RX5XX's.
HEVC is enabled in X4000 driver but does not play a Sony 4k 10-bit video through the RX580 but uses the CPU.
I have to set forceOfflineRenderer=NO in /S/L/PrivateFrameworks/AppleGVA.framework/Versions/A/Resources/Info.plist for my Board-ID for iMac13,2 for it play that Sony camp movie.
In iMovie & FCPX, I cannot share video to HEVC 8-bit as I have IGPU enabled. Both those app will not use the RX580 to encode.
Quicktime Screen recording does not work (not found a solution yet).
Basically, 10.13.4 update does what RadeonDeInit (and HEVC enabling without a dummy kext) but for me I still have to do more to get the Apps I use to work properly. Hence the update does not quite enable all AMD cards "OOB".
