Question

Apple M3 Max. Screen stopped working. randomly works and then goes black

Got up opened my Mac and no screen, just black. Tried a restart, no luck. Held down power button and restarted. Nothing. plugged in my hdmi monitor, nothing. Power cycled the Mac, nothing. Turned on and plugged in my iPad. Sidecar works used that to back up my Mac and check a few things. Did the updates.

still nothing. Called apple support and need to send my Mac in. While waiting for the box to return my Mac it will randomly work with the built in screen and then I'm back to using my iPad plugged into as the monitor.

Also It keeps having these crashes. Kernal panic, Display driver error, DisplayPort family failed, CPU caller kernel panic.

Any suggestions?

Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by a senior contributor here, and uses mostly system calls and simple tests to collect often-needed information.

it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.

if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.

Use Etrecheck Pro for free:

The amount of data you get can be daunting. If you POST your report, some Readers here are willing to look over those reports, and can provide valuable insights.

Then start a reply on the forums, click the "additional text" icon, and PASTE
