Yes, erasing and imaging could blow away the AHT partition. I did another in-place OS restore.

I still had the same problem. My first assumption was that the weird behavior was caused by an update to that program. But I checked, and it was actually the same version of the program that I had been running for the past year. The developer had upgraded the program, but hadn't offered any kind of upgrade discount. Since it had been meeting my needs, and running perfectly, I had chosen not to buy the upgrade.

However, once the crashing started to occur, I downloaded a trial version of the upgrade.

It and only it crashed when touching the menu bar. Now, I had verified that the behavior was repeatable on multiple versions of the same program. I contacted the developer, and we went over the crash logs. There appeared to be an error generated in the main UI code for the Mac, but not for that application.

A few days later, another application suddenly wouldn't launch. Or, more precisely, it launched, then immediately exited back to the desktop. This error wasn't as reliable, because it stopped once I rebooted. It was still odd. To diagnose the problem, I ran Disk Utility. My first go-to troubleshooting action is usually to repair disk permissions, since that's long been an easy way to fix minor problems. That's right, El Cap removed the disk permissions repair option because it interferes with system protection.

Everything turned out to be fine. Except my applications were still acting wonky. At that point, I started to wonder if I had a rare Mac hardware problem. I've had a lot of Macs over the years. I have had one or two hardware problems, but they've always manifested right after purchase. I've never had a machine fail years into use, so hardware failure was pretty much at the bottom of the list in terms of things I considered checking.

The generation of Mac minis prior to the currently shipping one were quite user modifiable. Mine is a generation older than the newest ones. Since I had run out of ideas as to why the machine was malfunctioning, I decided it couldn't hurt to run the hardware diagnostics.

Since my machine is a late machine, I used AHT. Typing 0x7bda into Google yielded nothing. My RAM was four year old aftermarket Crucial RAM, which had been powered on and running on the machine pretty much nonstop for all that time. The next day, I had the RAM in hand. My late Mac mini is extremely easy to open. You simply flip it over, turn the big black base slightly, and pop it off. The RAM is right there. RAM Replacement takes about five minutes.
