M2 Studio crashes and restarts daily

From EtreCheck report:

panic(cpu 0 caller 0xfffffe00213dfe68): DCPEXT1 PANIC - ASSERT!AFKSeri

alize.cpp:548 - iomfb_video_async(16)

The issue is most likely due to your external display.

DCP == Display Co-Processor

EXT1 == External 1st display

The M-series Macs can be tricky with external displays. It would really help to know the exact make & model of the external display as well as how that display is connected to the Studio Mac and which port on the computer is the display connected.

Also, are any devices connected to the external display?

I'm probably not going to be much help here, but this information will be needed for anyone else to better assist you so it would be best to post it now.

This sounds like the Automatic Computer Sleep/Wake/Crash issue that affected some Mac's and macOS versions.

As a test:

Turn On "Prevent automatic sleeping when display is off"

Set "Turn display off when inactive" to 5 or 10 minutes

Leave the Mac Studio On and only allow the display(s) to turn Off

Do not manually Sleep from the Apple Drop Down menu

Shut Down the Mac when away for a day or more

-------------

If using those settings fix the sleep/wake/crash issue..?

Then I suggest using those settings or upgrade to macOS 15 if your third-party software and hardware are compatible.

Thanks for the details.

I have put a call out to the regular forum contributors to get their attention to your thread. You should be getting some assistance shortly. I'll definitely keep monitoring your thread since I am curious & wish to learn more about external displays on the M-series Macs.

You're welcome.

In the Energy settings, Turn On "Prevent automatic sleeping when the display is inactive"

This is the setting that is causing some Mac's to Crash when they are woke from sleep.

The Lock Screen settings, "Start Screen Saver ..." and "Require password after..." are optional.

I personally do not use the Screen Saver, so I have "Start Screen Saver ..." set to Never.

My Mac is in a secure location, so I have "Require password after ..." set to Never.

If other folks have access to your Mac when you get up and walk away...?

Then you should set "Require password after" to a minute or less.

Now it is starting to sound like your TM backup drive needs to replaced.

Eject, disconnect and set aside your current TM backup drive.

Connect a new external drive and start new TM backup on it.

You're welcome.

Please keep us posted on your progress...

Yeah' it sounds like Computer Sleep was improperly suspending third-party software or turning off port power to external hardware and causing the system to crash.
