@Lego, You must carry on with Preboot, as Big Sur 3 has some bug of not renaming back to the original name after install.

Not as yet, but will report back once done

 

Unfortunately it is giving the same error "Dependancy com.apple.iokit.IOHIDSystem fallback to com.apple.iokit.IOHIDFamily succeeded. Please fix your kext!"

Thank you Jake Lo, at long last I found a working one and I can now install without a USB keyboard & mouse 😝. Another thing, the touchpad is no longer sensitive 😛

The kext is for an Alps touchpad by 1Revenger1. I just made 2 changes the the keyboard and trackpad kext renaming com.apple.iokit.IOHIDSystem to com.apple.iokit.IOHIDFamily. Check your Battery status is working, if that's working, then the touchpad preference should be enable.

From your bootpack, looks like you're using an old version of ACPIBatteryManager, try replacing it with SMCBatteryManager. Attached version works for BS.
