mac left click on trackpad and mouse not working
May 28, 2022 - Left click on my 2021 MacBook Pro not working on both trackpad and mouse. I’ve updated the OS and re-booted the computer several times and it will sometimes work for a short time before it stops working again. Because it is both a trackpad and mouse issue, it seems likely to be a software issue, not hardware. Any suggestions for things to try beyond just re-booting? Thanks for any help you can give.
