keyboard, trackpad, mouse become unresponsibe
This MacBook Pro M1 I bought in Dec 2020 and it has worked fine. About a week ago and twice this evening the system no longer responds to pressing keys, tapping the trackpad or pushing the mouse. The mouse cursor moves around but does not respond to clicks. The only way I got it to respond was by tapping the Siri key but she could not fix the mouse, I called Apple Support that had me press the Option Command P R keys after shutting down the system and pressing the power on key. That did not appear to do much and I read that it really does nothing with a M1 system. Thoughts?
