- ApfsDriverLoader.efi

Sleep : Not working

Audio : Layout 2 - When I select my screen asus tuf to output the sound, I can't use the + and - volume keys of the keyboard, I can only use them when the "built-in speaker" option is selected but since I only have the screen speakers for the moment...
2nd problem, as soon as I physically turn off the screen and then turn it back on later, the screen's speakers are no longer recognized, so I have to reboot to get sound again.

BT : If I'm with the SMBios MacPro 7.1, the bluetooth card is not recognized by the mac, but if I switch to SMBios 19.1 the bluetooth works, do you have any idea what the problem is?

I don't have hardware acceleration (when I launch the "videoproc" software to check, nothing is activated). Do you have an idea how to do this?

If you have any suggestions for those problems and to improve my hack, or to simplify my EFI file for more efficiency, I'm interested, thank you (this forum is a goldmine for a beginner like me)
