System refuses to accept input form keyboard or mouse

Intermittently my iMac doesn't respond to the keyboard or mouse for anywhere from 5 to 10 seconds. Characters I've typed may appear very slowly, or not at all, and clicking accomplishes nothing.

Sometimes this is accompanies by a beachball. After a while it clears up and goes back to normal, only to happen again, usually in less than an hour.

I am running 10.14.6 (Mojave) on a late 2015 iMac with a 4GHZ Intel Core i&, and have 32 GB of RAM installed.

Activity Monitor shows memory pressure as fine and neither Techtools nor Disk Utility suggests any problem with disks.

I am using an external SSD as amy system drive, because the SSD part of my hybrid seems to have problems, but have been doing this for quite some time, starting well before this issue arose.

iMac 27″, macOS 10.14

Hello,

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode?

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Whew, they've changed pastebin & made it harder, but after pasting in, click Create new paste button, then Embed button, then copy the URL...

The important part of the above would be...

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
