For what it’s worth, I saw the same issue after restarting my laptop a bit ago.
I’ve since attempted to download the latest version of Docker from here: Mac | Docker Docs but when I attempt to install (by dragging to my Application directory from the opened dmg file), I get
“Docker” is damaged and can’t be opened. You should move it to the Trash.
I’ve attempted to run the commands mentioned above as well, no luck. I’m not actually sure about next steps, I’m not sure I’ve ever run into this particular error on my Mac so am not certain if there is an easy solution.
