General EFI Question

[atw58]

Appreciate you for sharing your EFI folder. I have the same T480 h/w configuration and wish to install Big Sur and beginning by comparing my EFI based on Dortania's guide to your configuration.

My naive question is are all the 17 SSDT necessary. Many I have not seen in the guide. Similarly 30 kext files is much larger than the 14 or so I gathered.

Thanking you in advance for input.

I think you will be fine by using the EFI folder as default without altering it.. Worked like a dream.. (Do also have the same hw configuration)

Much progress based on your EFI and config.plist. Finally booted installer, installed Big Sur and after an initial test everything seems to work. Key to overcame boot loops and kps were #3-6. Read many posts and Dortania guide very closely.
