OK, I'll redo it and take a pic. There is no progress bar though, that's why I don't think anything was happening. I'm gonna wait until I start cooking dinner so I won't have to use my iMac which is in my office without a comfortable chair!

A funny thing happened when it was doing it's thing though. It did a test and then said there is either something wrong with your power adapter or it's not plugged in. Plug it in and we will check it. I did that. But I was told to disconnect everything, including the AC adapter (their words) before I ran the test. So, that made no sense. Anyway I finished following the commands but it really, really doesn't look like anything is happening. I'll try again.

Is something happening and I just can't see it? How long does it take? Good thing I have my iMac to post here for now.
  • Apple Diagnostics take a long time as they are testing every memory cell, every CPU function, etc.
  • How long depends on how much memory, how much storage, how fast the processor is, etc.
  • Each version of Apple Diagnostics is a little different so I can't say for sure ir what you are seeing is normal or not.
  • In general, as long as you see the progress bar the tests are still running. When completed it will either say "No Issues Found" laugh or a list of codes shocked If you get a list of problem codes then your only option is a trip to the Genius Desk at the Apple Store for full up diagnostics and repair or replacement. mad


If you are unsure, confused try taking a picture of your screen with your iPhone and posting that for us to see what we can discern.
