  1. It seems that 10.14.1 has broken AppleGVA-provided hardware video decoding, where before it was working fine on 10.14.0. My current config: - MacPro5,1 SMBIOS with E5-1650v2 CPU - Latest WEG/LILU, with boot-args "agdpmod=pikera shikigva=32 shiki-id=Mac-7BA5B2D9E42DDD94" (so using iMacPro1,1 SMBIOS for GVA) - Sapphire Radeon NITRO+ RX 580 (I also tested on a Sapphire Radeon Pulse RX 570) This worked fine in 10.14.0. I don't use iTunes DRM/Airplay or FCPX, but things that did work: Exporting videos out of Photos app, system-provided hardware decoding (specifically videos in Vivaldi browser, since they fall back to macOS due to not providing their own video stack). Self-compiled VDADecoderChecker reported "Hardware acceleration is fully supported". In 10.14.1, I can't get any decoding working. Stuff I've tried: - Other board-ids, either in SMBIOS or via WEG - Dummy kexts to ensure IOGVAHEVCDecode / VTMaxDecodeLevel / etc are set - Removing WEG/Lilu - Other Shiki flags - These preferences: defaults write com.apple.AppleGVA forceATI -boolean yes defaults write com.apple.coremedia hardwareVideoDecoder force None of those things worked for decoding acceleration. You can replace AppleGVA.framework in /System/Library/PrivateFrameworks with the 10.14.0 version, which does work. I don't like this solution, though, because it's likely to cause more problems, especially in the long run. Perhaps this patch no longer works? It's way out of my depth, though. I don't have that flag set now, but I did experiment with it. I attached the 10.14.0 AppleGVA.framework in case anybody on 10.14.1 finds this thread and wants to revert, but doesn't want to go through the trouble of digging it out. Happy to hear other suggestions or ideas for solutions! AppleGVA.framework-10.14.0.zip
