Hi vk2emp!! I've just use your EFI on my Mobo and it works perfectly for me. MSI Gaming Plus AC B450i.
I've just realized I don't have Bluetooth working. The icon is missing, what I don't understand is that on Catalina everything works !!!!
Thanks a lot.
I ´m trying to usb mapping but when I download the file , it says it not found.
I have a B450i gaming plus ac with AMD 3 1200af.
Bluetooth is missing at all from system preferences.
Anybody can help me with this?
Thanks in advance...
