Why is my Mac Running slow?
Sophos may be set to search archives, which will both slow down your Mac and cause multiple error messages from Sophos. It's easy to fix.
- Click on the Sophos shield on the right side of your menu bar.
- Click on "Open Preferences..."
- On the On-access Scanning" tab which is the default tab, make sure there is NOT a check in front of "Scan inside archive and compressed files". That should speed things up.
