I upgraded my MacOS from High Sierra to Catalina and now I find that after screen unlock, the trackpad click becomes unresponsive. I have to go to desktop (dragging three fingers up) and select a window (of any app) to make the trackpad click responsive again. I didn't have this issue on MacOS High Sierra. Please help in resolving this.

Do you already have the latest version (10.15.4)? If not, try to update, if yes, try the following:

1) Reset your Mac's NVRAM or PRAM.

2) If you continuing experiences issues, try to reset the SMC of your Mac.

I hope that works.

  • I already have 10.15.4 and I tried both but to no avail. The issue is still there.

This was happening due to the Right Zoom application running in the background. Once I removed that application from the login items, the issue got resolved.

  • Did you have Right Zoom installed on High Sierra?

I'm facing the same issue. What I've noticed is that the system looks for a wireless bluetooth mouse. After the timeout the trackpad starts working.
