Currently in Safe Mode where everything works, this is frustrating lol. Will try this when I boot normally again.
Just a question do you have a com.apple.bluetooth.plist in Library/preferences/ and ~/Library/Preferences/ByHost? I don't have these
update: I added the device id (tried 9b3e0000 but the iGPU ID of my processor is actually 0x9BC5, so I tried c59b0000 as well) but still no joy when booting MacOS normally
Downloaded videoproc and it seems that hardware decoding is successful:
