Since updating to Big Sur 11.6 my MacBook Pro touch bar has stopped responding

Since updating to Big Sur 11.6 my touch bar has spotted responding, I can see all controls and the controls change with differant apps but does not respond to touch, I have tried various things like reseting SMC and in safe mode but still does not work, any ideas?

On the Intel Mac with T2 chip

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



USB Device: Apple T2 Bus

USB Device: Touch Bar Backlight

USB Device: Touch Bar Display

USB Device: Apple T2 Controller




try both—


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


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

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


If no resolve it typically points to a hardware issue.
