Description
MacBookPro16,2
Ubuntu T2 23.04 LTS (Updated to 23.04.3 LTS)
Downgraded from 6.5.6 to 6.1.57-1 LTS
Touchbar now works, but laptop will not resume after lid was closed.
Starts up with only touch bar illuminated and nothing else.
After a few seconds the MacBook will reboot on it's own and touchbar will no longer work.
Required manual reboot from within Ubuntu to restore touchbar function.
MacBook Pro is working normally if it is turned off every time before closing the lid.
Clean install, not dual booting, only performed apt updates and kernel downgraded to the LTS kernel.
[UPDATE]
macOS 14.1 Monterey is the last version of macOS this was running.
Just restored back to only macOS, all latest updates done.
Created partition for Ubuntu, ran firmware.sh on macOS
Booted to Ubuntu T2 installer, Installed Ubuntu.
In Ubuntu T2, ran firmware.sh to copy the goods.
Backed up /usr/firmware/brcm
Wiped computer.
Clean install of Ubuntu T2 without macOS
Migrated backed up brcm folder to /usr/firmware/brcm
Overwriting conflicting files
Downgraded to 6.1.59 LTS T2 kernel
