MacBook Pro M3 crashes daily r/t LG UltraGear monitor

I got my MacBook Pro M3 back in November of 2023 and hooked it up to a new LG UltraGear monitor right away. It is connected via HDMI. I do not recall any issues with it until after the last OS update where I found it to be crashing over night every night. I tried multiple troubleshooting attempts but finally found that my MacBook will only crash if the LG monitor is attached. It does not matter if the MacBook is open or not (I normally keep it closed and only use the LG Monitor as my display). I recently took a weeklong trip and left the MacBook at home. The monitor was disconnected from it and left the MacBook running and open and it did not crash that entire week. I did open a up a bug report with Apple regarding this as well as send them a daily crash report. I am hoping that this is resolved with the next OS Upgrade.

Kernel Panic is not ONE problem, it is one of Thousands of problems.

It is good that you found correlation to your LG displays. but not nearly sufficient. we need at least one panic report.


Kernel Panic Reports are stored in the Folder at:

/Library/Logs/DiagnosticReports


If you copy and paste that string into:

Finder > Go menu > Go to Folder


it will take you to the Folder where those reports are stored.


Kernel panic reports are named with Date&Time and start or end in ‘panic’

If you find one, please post the entire report here, by using the “additional text” Icon in the reply footer (looks like a paper with writing).


Please don’t post more about 20 lines of any other types of reports — they are interminable, and any information useful for this purpose is on the first screenful.


If you post your kernel panic here in its entirety, using the additional text icon in the reply footer, we do have some Readers (typically with developer background) who can attempt to interpret those panic reports. Even if no clear symptom emerges, this can still save a step if you DO need to contact Apple support later, because Apple Support specialists can read the panic reports you posted here, if you tell them what discussion or what Avatar.
