3 years ago You said you have macOS Mojave which works perfectly but I do not see where you came to say it Your EFI is not good Reinstall new macOS from USB installer erase the SSD Probably your issue is from the High Screen laptop See this https://github.com/chris1111/HP-Probook-EliteBook-Package-Creator-OC/issues/2#issuecomment-679373248
I have test BS 20C69 show days a go no Issue
Hello, I have HP Elitebook 9470m i5... I installed BigSur 11.1(20C69) and did the post installation correctly but nothing works, only graphics acceleration The audio works only when I install VoodooHDA manually but couldn't manage to get everything else work. I was on Mojave and everything worked perfectly except for wifi because of the incompatibility.
this is my efi EFI.zip
