My iMac (Retina 5K, 27-inch, 2017) continually restarts itself, followed by the message, "Your computer restarted because of a problem."

Thank you; I'm familiar with this link. It suggests several different (and potentially very involved) "avenues of investigation." I've already tried updating my OS, ensured all my pre-installed software/apps are up-to-date and checked my hardware peripherals. I was just hoping anyone had an insight about a specific "bug" I could zero in on. Unfortunately, I'm probably now left with systematically deleting my third-party software, and removing the RAM I added, to see what happens. (Sigh ... )

I'm frustrated and disappointed--considering I've owned my iMac for less than one year. How can it be that simply adding on common, widely used third party software (in my case, MS Office 365, the Abobe cloud-based creative suite, Photomatix Pro and Sonos); and installing eight more gigs of RAM (purchased from Other World Computing) could so "upset" Apple's supposedly time-tested, robust OS? Or do I just expect too much??

Yes, I tried unplugging all my USB devices (external HDs) and running just with the mouse and keyboard (which are both wireless). The problem persisted.

I'm still going the try the diagnostic check with EtreCheck (as recommended by BDAqua, above). I'll post the results of that.

Thank you.

I downloaded and ran the Etrecheck diagnostic tool, which produced a Report of my iMac's issues (all of which fall into the "minor" category). With my limited technical understanding, I can only infer from the report that I have "conflicts" with some of the software I have loaded onto my computer. Therefore, I welcome community members who're willing to review my EtreCheck Report (which I've pasted below), and offer me practical advice on how I might proceed to correct these issues.

I appreciate any/all helpful advice!

First, I got the extra RAM from OWC.

Second, thank you; I’ll try your suggestion (about testing after removing the 16 gigs of extra RAM). I’d definitely be willing to reconfigure my RAM modules if, after testing with the original 8, that seems to be related to my issue

Yes, I used it. It produced a list, however, that leaves me me with new questions. For instance, what to do about all the programs that are 64 bit, but which contain small “extensions” that are 32 bit.

But I did learn of a few 32 bit programs that I never use, and which I simply deleted.

‘K, thanks. I’ll start with those. (Many of the 32 bit apps appear to be related to installing their corresponding programs. Others seem to be leftover from earlier versions of software that was subsequently updated. My initial thought was, “Oh, I can probably just delete those.” But then I wondered whether they retained some functional or essential relationship to the current “ver.” ... ?)

Anyway, I’ll begin by looking for updates for that first category (with the 32 bit “features).

Thanks, again, for your help & feedback.

Thank you--I'll give that a try!

It's a 2017 model, but I bought it brand new thru B&H. Thanks for the question.

I did see that on the report. I’ll take a look at that possibility, as well as my RAM configuration. I have an idea of at least one app that probably falls under that spec.

Thanks for your feedback!
