Docker for Mac 10.11.6 will not start, uninstall hangs and docker menu will not open when running

Something has gone wrong with Docker on my mac and I'm trying to remove and re-install versions but I can't get the menu open to do a factory reset.

Every version I install either says it will not run with this version of Mac OS, or it "starts" and puts the icon in the top bar but I just get the colored wheel when I mouse over it and the menu won't open.

What can I do to manually factory reset docker?

Solution 1:

I'd give AppCleaner a try.

Drop the errant app onto its open window (or you can set it to auto-launch if you throw an app in the Trash) & it will offer to clean out any associated files, allowing you to have a clean start.
