So I spent some time trying to switch to OC. Whilst it's still booting and dual boot working too, I have some issue with sound. The internal speakers only have very flat sound. Something must be wrong. And screen brightness keys stopped working. I basically used the kexts and ACPI's from clover and used Dortanias guide to create config.plist. Any suggestions? Since we still have the same notebook model, does it help if you share your EFI folder? Also, when switching to BigSur, you reckon it's better to update directly or do a fresh install and then recover from TimeMachine?
Thank you!
