HDMI audio - works just fine now, it wasn't my main concert. Not until I get a new monitor. anyway. But audio works fine all over and I can use my interface again with Logic. Removed NullCPUPowerManagement.kext & GeneruicUSBXHCI.kext With Clover, I applied the TRIM patch + the name fix for the GPU. Now it shows Intel HD Graphics 620 1536 MB IGPU PM (GFX0->IGPU rename) - I hope I did it right using SSDT-1.aml, my first attempt resulted in failure. as for native AirportAtheros40.kext can you please elaborate? My WiFi is not working and it's not support (Atheros 9565) and as far as Bluetooth, I actually rather disable it (I don't have any single use for this technology and never had) While we're on the subject, is there a way to just turn it off without physical disconnection? Also, for kext I'm now using Kext Utility, but I don't think I have much to change in that area by now (at least not until new MacOS) and finally, the USB injection, that will have to wait, holiday is over And again, attaching the file for future use and other comments and improvements.
