The user Diagnostic...not as definitive as Apple's own AST2 (Apple Service Toolkit) back bench diagnostic.

In or out of warranty you can get a free over the counter 'Apple Service Diagnostics' test /assessment

Make an appointment for a "hardware issue"

Maybe if you paint a bigger picture surrounding the circumstances and some details—something can be added here

Old issue, new issue, what changed?

What exact Mac is this..?

My iMac (Retina 5K, 27-inch, 2017) recently started periodically shutting down (without restarting). By typing the following into Terminal:

log show --predicate 'eventMessage contains "Previous shutdown cause"' --last 1h

I learned that the previous shutdown code was 0 in every case, for which, guided by a troubleshooting website, I reset SMC and NVRAM, after which the problem has persisted. DriveDX report is clean, most recent EtreCheck report attached. As mentioned, Apple Diagnostics reported ADP000.

To restart, I've been needing to remove and then reinsert the plug before powering on.

I'm just trying to troubleshoot as much as possible before bringing it in for repair. I appreciate the help.

Many of us have come to that conclusion via many, many topics here in the Apple Support Communities regarding those types of apps and the damage they've done to systems and 3rd party apps.

There is no reason to ever install or run any 3rd party "cleaning", "optimizing", "speed-up", anti-virus, VPN or security apps on your Mac. This user tip describes what you need to know and do in order to protect your Mac: Effective defenses against malware and other threats - Apple Community.

There are no known viruses, i.e. self propagating, for Macs. There are, however, adware and malware which require the user to install although unwittingly most of the time thru sneaky links, etc.

Anti Virus developers try to group all types as viruses into their ad campaigns of fear. They do a poor job of the detecting and isolating the adware and malware. Since there are no viruses these apps use up a lot of system resources searching for what is non-existent and adversely affect system and app performance.

There is one app, Malwarebytes, which was developed by a long time contributor to these forums and a highly respected member of the computer security community, that is designed solely to seek out adware and known malware and remove it. The free version is more than adequate for most users.

Yes. Power supplies have many components, and especially for laptops and Mac Studios, and iMacs with the proprietary connectors. Fraying on the cable can be a problem, and with magsafe connectors, you also have a magnetic shield on the port that cane get loose with age or in the process of taking apart. The only part the diagnostics can realistically detect is the circuit board part that controls where the power goes on the logicboard. Water and moisture from liquids can make mincemeat out of any power supply. Some computers have a natural tendency to condensate inside, which can yield to the demise of power supplies. With age, capacitors can break down too, and lead to issues with inverter connections on the display.

If an error is detected, it is to be believed. As a computer repair person, I don't just look at the diagnostics but any symptoms, are they present on both internal and external displays, and if they are related to Dark Mode or Color correction issues, or a genuine hardware problem.

What is your indication that it is failing?

PowerMyMac sounds like it is the culprit.

Use Reggie Answorth AppDelete to remove it by dragging the application over it.

Never install any optimizers, anti-virus utilities, or other utilities without verifying whether or not it is used for diagnostics or optimizing, and how to use it.
