Docker Desktop won’t reopen on macOS

After months of waiting, I finally received the MacBook Pro that I had ordered
back in February. Thus far, it’s been a solid machine with exceptional battery life, but not without it’s quirks.

One recent quirk was with Docker Desktop. I had the app open and I quit it
instead of just closing the window. Things seemed to have went fine, the app
appeared closed, and the menu bar icon went away.

Since I was still messing around with Docker, I went to reopen Docker Desktop
again. Upon doing so, nothing happened. Over and over and over, nothing.

My theory is that something went horribly awry with trying to shut down the
Docker daemon, and that left things in a borked state. I also suspect that a
reboot would have fixed things, but that would have just been too easy.

When encountering these types of situation in Linux, I’d reach for the trusty,
killall commands. Sadly, killall Docker didn’t get me moving again, and
killall docker just spit back an error due to there not being a process with
that name.

Activity Monitor to the rescue!

Upon closer examination, there were a handful of processing related to Docker,

  • Docker
  • Docker Desktop
  • Docker Desktop Helper
  • Docker Desktop Helper (GPU)
  • Docker Desktop Helper (Renderer)

And wouldn’t you know it, there WAS a process named docker running too!

I went ahead and selected all of the Docker* commands, and hit stop, and then
clicked Force Quit.

When I tried running Docker Desktop again, things started up as one would have
