    I upgraded to High Sierra a few days ago. Running a 2017 iMac (18,3).

    Today I have had trouble with Preview stalling just about every time I use it. Just now all my printers disappeared so I cannot print. When I go into System Preferences/Printers & Scanners, nothing happens when I click on the "+" sign.

    I have restarted several times.

    In activity monitor CPU Pressure is running under 15%, with System between 5% and 10% -- Memory is using less than 5GB of 16GB.

    Any ideas?

    Activity monitor showed that System Preferences was not responding for a brief time, but it no longer in red now. It also shows 23 recent hangs.
