The curser on my mac pro will not respond to the commands to open a page or select anything. Any suggestions
I am using a Mac Pro and had problems with my curser not responding to commands. I had not upgraded from Maverick. I called apple and the first step was to upgrade to El Capitan 10.11.3. I did that and still have the problem where the curser will not respond to commands intermittently. It will stop unexpectedly and restart unexpectedly. Any suggestions?
