panic kernel

Here's some general links about KPs.

If your Mac spontaneously restarts or displays a message that it restarted or shut down because of a problem - https://support.apple.com/HT200553

Kappy's April 2018 post on startup troubleshooting - https://discussions.apple.com/message/33250632#message33250632

In your case I'd unplug individual components until you trace and see which one is causing problems then find a replacement for that.

Actually seeing the first part of the message can tell you which kext may be loading at startup and is failing.

just spoke with apple costumes service and they told me to get into safe mode also

he told me that with the safe mode I can possibly trace the cause of this issue

again as i said before I'm suspicious in the dongle or in the screen

for the main thing is that he told me that if the problem show up again in the safe mode so probably is the MacOS hardware

but if its not coming back so its should be the external (screen/keyboard......)

You can post your Kernel Panic report in their entirety here,

From the Finder>Go>Go To Folder, copy and paste:

ends in .panic post the whole report.

You can also find panic reports with Console.app.
