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.

ajay.

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.
