iMac M3 2023 Keeps Restarting - Kernel Panic

I'm not pointing the finger at you or the local repair shop, but someone has not properly format the internal drive.

Basically the volume structure is wrong and the entire Apple drive needs to be reset to the factory settings.

see > Erase your Mac and reset it to factory settings - Apple Support

If that doesn't work, then take it to an Apple Store or AASP and have them properly reset it to the factory settings.

Startup in macOS Recovery Mode > open Disk Utility > Erase and Format APFS.

see > Use Disk Utility to erase a Mac with Apple silicon - Apple Support

Then Reinstall the macOS while started up in Recovery Mode.

see > How to reinstall macOS - Apple Support

If that doesn't work, take it to your local AASP.

see > Official Apple Support

and > Find Locations

Any one of those App's or version, may not be compatible with the Silicone Mac or macOS 15 Sequoia.

An excellent tool for finding the problem, is EtreCheckPro.

On the hardware side:

1) The APPLE SSD AP1024Z 1.00 TB internal drive is not formatted correctly.

2) The Satechi Dock, the Quad Cortex or the Realtek might also be causing a problem.

On the Software side:

1) Secure Boot: Úplné zabezpečení

2) MS Office

3) One Drive

4) Chord

5) Neural QC

6) Guitar Pro 8

7) Cortex Control

8) Screen Time Widget

The internal drive not being formatted correctly is most likely the cause of the Kernel Panic's.

The Satechi Dock, the Quad Cortex and the Realtek can easily be disconnect for testing.

I never heard of the Secure Boot Úplné zabezpečení thing, so that one is disturbing.

Make sure MS Office, One Drive, Guitar Pro 8 and the others are compatible.

Kernel panics can come from bad software or faulty external hardware.

What software did you add after you returned home..?

What external devices did you plug in after you returned home..?
