Macbook Pro M3 MAX crushing every days and reboot

The usual symptom for cables that are not quite fast enough is the display quietly goes blank. Crashing is something else.

But if you are connecting with thunderbolt or USB-C adapter, try moving to a different computer port, and see if the symptoms change.

if no improvement, you will need to contact Apple support, and ask for a specialist to contact you (or file a formal bug report) to get a specialist trained in reading panic reports to interpret yours. if they find there is a likely Hardware error, they can DIRECT an Apple Authorized Service provider to replace your mainboard.

they can read what we post here, but they do not take our word for conclusions. They have a somewhat more rigorous process.

if you just show up at the Genius Bar, they are most likely to run diagnostics, have it PASS, and tell you its fine and do nothing more.

DCP means Display Co-Processor Ext1 panic

IOMFB is I/O Mobile Frame Buffer

interrupt handler gated access to reading something had a problem.

EXACTLY what model display is this? Samsung uses the same name for several.

how is it connected to your Mac?

I recommend you follow their advice BUT, copy those panic reposts to a USB thumb drive, and PRINT out a copy on paper.

If they are not willing to change the mainboard based on what they CAN see, ask them to use their internal support network to get someone to read the panic reports and provide strong guidance.

You should also run the User diagnostics yourself, but they generally only indicate GROSS failures.

Remember that if the mainboard is swapped out, your FILES on its drive will NOT be returned you. You MUST have a copy on a trusted backup before submitting your Mac for service. (post back if you need advice about how to create such a backup.)
