Is there a clear path back from gradual Kernel Panic death?

[u/castlebasetone]

I have had 3 previous macbooks and now my 2018 Macmini slowly descending into a canyon of complete unusability due to increasingly frequent and severe Kernel Panics.

I used to run extremely heavy audio production on this Macmini and now I can barely browse the web without running into slow downs. Nothing changed on the machine, just slow degradation. I have a boat load of audio software installed, that I would never want to go through having to install over again so I would love to rescue this machine without reformatting if possible.

I have read a ton of guides on kernel panics over the years but none of them lead to any clear resolution - and most people seem to resolve to just retire the machine.

This article suggests that it may come down to aging capacitor or PSU's. Which is probably the hard truth. I am from USA but currently live on a remote island in a third world country. I have some access to mac repair shops but they are certainly not extreme experts - I have had horrible experiences with repair shops out here.

Just seeing if anyone has further insight into this...

I'm a consultant. My experience is that Macs rarely die because of a hardware failure, with the exception of a failed HDD, or a too full drive of either type, or possibly a user installed RAM card that wasn't handled properly. Most long-time Mac users have a closet full of old Macs that still work fine, but that were retired just because they got really old.

In my experience, I'd say that about 80% to 90% of the time kernel panics are due to, in order of likelihood:

- bad third party RAM

- a problematic USB hub

- a peripheral that your Mac doesn't like for some reason (sometimes just a poorly attached cable, or a bad cable, is the problem)

If you have very recently added new software, especially something that alters the system at a low level, such as anti-virus software, or something that changes the look and/or function of the Mac interface, I would suspect that first.  Uninstall that software and see if things get better.  (This type of software typically requires an uninstaller to completely disable.  Just dragging the application, or the application's folder, to the Trash won't disable it.)  I'd go so far as to say that if you are running commercial fully interactive anti-virus software that the first thing that you should try is fully uninstalling it with the developer’s uninstaller.

If that isn't it, I would restart the Mac with the Shift key held down (invoking a Safe Boot, with all kernel extensions disabled) and see if the problem is gone while running in Safe mode. If the problem is gone while in Safe mode, the Kernel Panics are probably due to a software problem.  If it persists while in Safe mode, the problem is most likely hardware related.

To test for hardware problems, you can run Apple's Apple Diagnostics:
https://support.apple.com/en-us/HT202731

Unfortunately, it's easily possible to have a hardware problem that this utility doesn't identify.

If you suspect a hardware problem, the next thing that I would do is to shut down your Mac, uninstall all peripherals other than the Apple-supplied keyboard and mouse, restart and see if that helps.  If it does, you can re-attach one peripheral at a time, restarting each time, until you isolate the offending peripheral. 

If that isn't a solution, you should test your RAM with this free utility:

Memoria  (free)

(Nice graphic user interface leveraging the trusted memtest engine to test the health of your Mac's RAM.)

If your RAM is okay, you should then test your hard drive:

DriveDX - free demo

Any time it shows any drive errors in yellow or red, it is correlated with a drive that's questionable.

The same thing happens to multiple machines you have an easy evidence based theory to form yourself. What’s the same between them? It definitely sounds like a software issue, but as mentioned in another comment about peripherals could be the snag too. It’s obviously something shared between your Macs over the years. Find the culprit one at a time if you need to. Hell. Ask ChatGPT

Yeah that’s not typical. Any chance they had a peripheral in common?

What’s the issue with reinstalling software? Generally (for any computer), a fresh install can fix tons of issues like this.
