Mac mini 2018 keeps having kernel panic reboots

Dealing with Kernel Panics

Disconnect any third-party peripherals including any USB hubs. Use safe mode to isolate issues with your Mac - Apple Support then boot the computer into safe mode. See Diagnosing problems- crash, freeze, panic, or spinning beach ball?, Don’t Panic! Understanding & Troubleshooting Kernel Panics in macOS, and How to fix kernel panics after installing OS X updates | MacIssues.

Kernel panics are indicative of possible hardware failure, so you should Check your Mac with hardware diagnostics or AHT. Read the kernel panic log: Mac OS X- How to log a kernel panic.

If you have no success figuring what is happening then you may need to examine the software you have running when the panics occur. Be sure it’s all current. If you must to resolve the problem erase the disk and reinstall macOS. Follow this outline to reset the computer to the factory-new state: Factory reset of your Mac - Apple Support.

Boot Into Safe Mode

1. 1. Restart the computer.
   2. Immediately, at or before the chime, press and hold down the "SHIFT" key.
   3. Release the key when the Apple logo and progress bar appear.

The startup process will be slower than normal. When it is completed you will see the login screen. Enter your admin password.

What happened in safe mode? Did the computer panic? You say you tried to install macOS from scratch but not if you succeeded in doing so. Before restoring third-party software was the computer operating without kernel panics? It's very difficult diagnosing the problem without complete information.

The panic logs are not crash logs because kernel panics and software crashes are quite different phenomena. Your panic logs are difficult to assess because what they have provided is only useful to someone with the right debugging software and hardware. The logs don't tell you what program crashed. They only tell you what process was running at the time the panic occurred. As you noted these were Chrome and the kernel_task. Unfortunately, I have no idea exactly what caused the panic.

I had you try safe mode because it disables third-party extensions and login items. It also rebuilds certain caches. If panics are still occurring in safe mode that usually means hardware failure. In today's computers hardware failure means replacing the motherboard. I suggest you take the computer and copies of the panic logs to your local Apple shop where they may be able to identify the culprit.

I would usually suggest at this point that you replace your installation with the one you upgraded. That could be in a backup of the prior system or you can do it using Internet Recovery:

Internet/Network Recovery of El Capitan or Later on a Clean Disk

     If possible back up your files before proceeding.

1. Restart the computer. Immediately after the chime hold down the (Command-Option-Shift-R) keys until a globe appears.
2. The Utility Menu will appear in from 5-20 minutes. Be patient.
3. Select Disk Utility and click on the Continue button.
4. When Disk Utility loads select the target drive (will be the out-dented entry) from the side list.
5. Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
6. Set the partition scheme to GUID.
7. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
8. Click on the Apply button, then click on the Done button when it activates.
9. Quit Disk Utility and return to the Utility Menu.
10. Select Install OS X and click on the Continue button.

The above procedure should install the version of macOS that came with the computer out of the box. When you do a fresh Erase and Install be sure to test it thoroughly before installing any third-party software like Chrome and/or add-ons. Keep the system clean. That way you will better know whether you are dealing with a true hardware failure.

No panics in safe mode is helpful. See My Mac only runs properly in Safe mode for a discussion of what is disabled in safe mode and what you might look for that could cause panics. This is useful when the computer only works properly in safe mode. That seems to be your case. I might add that you should not use FileVault or full disk encryption. If you are not using the computer for the NSA, CIA, or FBI, then you don't really need it. Both can cause worse problems than they solve.

This article, Use safe mode to isolate issues with your Mac - Apple Support, describes a process for isolating possible sources of problems.

I'm a big proponent of testing out a completely OOTB, pristine installation that has nothing added to gum up the works. When panics occur then you know it's hardware. In your case the two major pieces of hardware to look at will be the disk drives connected and the RAM that's installed. RAM from the factory may seem fine but has a malfunctioning bit or byte in a chip that is not always bad. But when it malfunctions it will cause panics. With that in mind I would take the new machine back and insist they replace the RAM. If you have installed your own RAM, then remove it. The Mini uses external drives, so consider replacing what you are using with another.

Beyond this I don't know what more to suggest trying other than having this one replaced.

Problems that do not occur in Safe Mode but occur when booted normally can be due to login items or launch agents or daemons. In this case I suspect the GoPro stuff.

I'm wondering if their crashing has anything to do it with the problem.

Can you see if the panics go away if you uninstall that?

In any case, I see very little reason to have these things run as login items - this means that start every time you login, and are probably always running, even if you are not connecting your Gopro camera...

No obvious bad actors in the report, but it might be useful to see the more detailed diagnostic.

In System Preferences->Security & Privacy->Privacy, click Full Disk Access, then authenticate and add Etrecheck to the list.

Run Etrecheck again and post the extended report.
