All web browsers crash my mac

I finally solved my crashing issue. After deleting all of the cache files and disabling browser extensions the crashing reappeared. Then it dawned on me, when my Mac crashed it wasn't actually a crash. The keyboard, mouse and drawing tablet all locked up, but the computer functions kept working. For example, my After Effects renders completed, and Spotify kept playing music even though I had absolutely no keyboard or mouse control. Those functions were completely frozen as if the computer crashed.

Most Mac users will not encounter the problem I was having with my computer locking up. It was due to the old Logitech driver that I was using and its lack of compatibility with the Logitech driver for El Capitan.

First, I started using my Mac mouse instead of my Logitech mouse. The crashes stopped. Then I updated the Logitech mouse driver and started using my Logitech mouse again. It still didn’t crash. Then I updated my home machine Mac OS Mojave and the appropriate Logitech driver for Mojave. It hasn’t crashed since. So far it has run perfectly well for three days. I still have to update Fusion Suitcase, Disk Warrior, and TechTools Pro for Mojave. Other than those apps everything else seems to run just fine.

Hi Grant,

Thanks for the response. I am going to stick with Sierra for now. But there were a couple of things that I did that seemed to correct the problem. I deleted all of the cache files from Safari, I turned off all of my extensions and add-ons in all of my browsers, and then I rebooted my machine. Once I performed all of those steps it hasn't crashed. This is a heavy computer use day for me. So far my computer hasn't crashed since this past Saturday. So, hopefully things are working correctly again.

I appreciate your help.
