On an Intel Mac —


—Try resetting the SMC https://support.apple.com/en-us/HT201295


Even though SMC controls the touchbar, some USB is in play, so this would be NVRAM (or reboot.)


—Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379

(get at least two-three rounds of the chimes when holding the NRAM Reset)

USB Device: Apple T2 Bus

USB Device: Touch Bar Backlight
