My iMac keeps changing the arrangement of my two add-on displays. The third one, the one in the middle, is the computer itself which always stays in the middle.
I'm running High Sierra 10.13.6. It's a mild annoyance, but still annoying nevertheless.
All three monitors have the dock and menu bar. Apparently no one else is having this problem because I cannot find a fix anywhere.
How can I ensure that the way I arrange my displays does not change?
