Didn't know where to post this. I have two macs. A MacBook air & an iMac both running the latest version of the OS Yesterday the mouse on the iMac stopped working. What I mean is it would move. But it wouldn't CLICK I tried several different mice. No luck. So I used the laptop to access the iMac & backed stuff up, etc. Today the trackpad on the MacBook had the same problem. Move but no click. I hooked up some different mice via USB. No good same problem. This is just too much of a coincidence. HAS THIS HAPPENED TO ANYONE ELSE? Is it solvable? Thank goodness for the iPad with which I'm able to post this.
