Touchbar does not work #7

Closed ysukhovey closed 6 months ago

ysukhovey commented 6 months ago

Touchbar does not work on Macbook Pro 18,2. Booting into MacOS (recovery and normal mode) does nothing.

I'm on noble, seeing this same issue, but I don't see all of the devices enumerated correctly on lsusb.

What did it end up being on your side @ysukhovey? Thanks!

Have you tried rebooting in macOS and then back to Linux?
