Title: `cmd + tap to click` is not working
On my new 14” MacBook Pro running macOS 12.1: Using a modifier key, such as CMD, in conjunction with tap-to-click does not work unless the modifier key has been held down for about a second or so; otherwise, the tap-to-click completely fails to register.
This issue was present out-of-the-box from the first day I used the system.
This issue has hundreds of reports in Apple’s and other discussion forums. It’s causing a lot of frustration because I use the “quickly press-CMD and tap-to-click” interaction many times throughout the day to open links in new tabs. This interaction works fine on my other (Intel-based) MacBooks running Catalina 10.15.7.
On the affected system, holding down CMD for about a second before attempting to tap-to-click seems to let the tap-to-click register; it almost seems there is some delay or timer that must expire once a modifier key is held down before the system will recognize a tap-to-click. I’m speculating here, but there might be some issue with palm rejection heuristics interfering with this interaction?
