My new iMac (July 2019) keeps crashing and I'm in need of assistance:

I've had 7 incidents in two weeks:

  • Four times when starting Final Cut Pro X I get a forever beachball.
  • Two times when starting Wine app (a windows emulator) I get a forever beachball.
  • One time when starting MacOS I got a forever beachball.

Each time I'm unable to shutdown or restart the computer afterwards. I get a grey "wheel" as it's shutting down that never finishes. Forcing me to shutdown with the physical power button.

I tried resetting PRAM & SMC. And I downloaded Etrecheck and ran it the next time I started FCPX and got a beachball. But then Etrecheck got stuck in a loop as well and never finished the report. So I was forced to restart (with power button) and I was able to run an Etrecheck report on startup (see below).

I then did a Safe Boot. And a Recovery Boot, where I ran Disk Utility's First Aid 3 time, getting an OK.

What are my options? My fear is that it's a hardware issue and that I need to contact Apple and return the computer (after spending two weeks setting everything up). I don't live close to a store and don't have a car. Hopefully it's a software issue that I can resolve somehow. Asking for this community infinite wisdom. Thank you!

Here's a screenshot of Activity Monitor when app stalled:

And here's an Etrecheck report made after crash, at startup:

EtreCheck version: 6.0.2 (6A004)
Report generated: 2019-07-26 02:55:02
Runtime: 1:25
Performance: Excellent

Problem: Beachballing

1 out 4 times apps like FCPX (and wine) beachballs and if I try a restart 
there's a spinning grey wheel. Forced to close down with holding down 
power button.

  • idk whether it's any hint of a cause, but I notice you have both Logitech Control Centre & Logitech Options - do you actually have 2 Logitech devices running on different dongles? – Tetsujin Jul 26 at 17:31
  • No I have only one Logitech mouse and the dongle is not even connected now. I will remove those (or atleast one). However I think this issue was present even before Logitech installs. – Emil Jul 26 at 17:51
  • Apple provides free support. Give apple a call. Run hardware tests. Boot up in safe mode. Try a safe boot. Shutdown your machine. Hold down the shift key. Poweron. The boot up will take longer than normal because the filesystem on the startup drive is being checked and repaired as needed. All about safe mode including what features and apps safe boot leaves out. Safe boot uses a software driver instead of using your machines video hardware. support.apple.com/kb/ht1455 Your machine seems to be fairly can of addon software. – historystamp Jul 26 at 20:05
  • Hard freezing like this is almost always hardware related. Call Apple and start the diagnostic process with them. It looks like the RAM is replaceable so they may send you new RAM if that is the issue and you won't have to send it off. – Thomas Nelson Jul 27 at 5:14
  • Thank you! So it turns out it was the external hard drive. For some reason the new iMac starts to stall when trying to access the drive. Its a new LaCie 4TB rugged drive. I've ran several tests of the disk and haven't seen anything faulty but I believe it was a mistake to format it in ExFat.. I think it could have something to do with this. Because since I removed the drive I haven't had a single issue for 5 days while I use to have a problem once a day with it connected (running the same apps). – Emil Jul 31 at 11:59
