Macbook Pro crashes when connected to external display with HDMI

Smae problem on a MBP M1 2021 running Sonoma 14.5. Connecting HDMI on a variety of monitors directly or through USB leads to a crash. Sometimes keeps displaying video on the external monitor but screen freezes up on the laptop and only a hard reset will fix.

I have the same problem. I have a 2021 MacBook Pro M1 (14.2.1 (23C71) . When I plug my computer into HDMI, sometimes is freezes and I have to hard reboot. I have tried different cables and different monitors. It will connect fine but then when I try to change something, it freezes. Very annoying and makes my computer VERY unreliable as a professional solution...

Same problem for me. It used to work, now it doesn't, in two locations where I hook up to HDMI projectors. I've changed nothing substantial except for OS updates (currently Sonoma 14.3.1). Maddening in professional situations. I hope it can be taken seriously and addressed.

I have the same issue. It’s very annoying to see a 2020 mac book pro cant handle a simple thing like HDMI. there is almost no other option rather than hard reboot. i couldn’t find any solution here or anywhere else.

Same issue here. MacBook Pro M1 on 14.1. Sometimes my MacBook freezes (image but not sound) and eventually crashes. It is caused be input on the keyboard or touchpad. In my case this only happens if I connect to my beamer via HDMI. If I connect to my monitor I never experienced anything like it.

Not sure if bluetooth has anything to do with this, but I was connected to my JBLs at the time(which in itself does not crash my macbook).

Another M1 user with the same issue. This all used to work fine, but now whenever I connect an HDMI TV or monitor after around 2 minutes the Laptops screen freezes. Sometimes I can still operate the computer via the external screen, so the entire machine isn't always crashing, but it becomes next to impossible to use. Other times it crashes.

Makes it impossible to use for professional use.

I used to have the same exact problem with my Macbook Pro from 2020 (Intel chip). Brought it to Apple Genius Bar several times and they never managed to re-create the problem so it was never solved.

I actually bought a Macbook Pro M3 last week and started using it today with a 2nd monitor and... it has just crashed when it went to sleep after 5 minutes. This is extremely frustrating.

I experience smae issue since autumn 2023. Very frustrating. At first I thought its related to bluetooth-connected devices. But after turning off bluetooth the issue is constantly repeated.

Once connected with beamver via HDMI it crashes after certain period of time. Sound continues. System and input are unresponsive.

I have the same problem with my Macbook Pro 2021 M1 Max when connected to external displays or projectors via HDMI. Tried various different projectors and HDMI cables, turned off bluetooth and other apps, the problem still exists and is incredibly annoying. This is really unacceptable for a 4000 dollar laptop, Apple please fix this ASAP.

I am having this same issue. It seems to be tied to the OS and therefore a solution seems at least possible. Failing to provide any working solution is grounds for a recall. Has any progress on this or did Apple sell hundreds of thousands of machines that cannot, and will not ever, be able to display on external monitors?

Adding my voice to this. Same exact problem. I have a 2021 MacBook Pro M1 Max running macOS 14.4.1. It's embarrassing when your $5,000 device freezes in a conference room full of stakeholders.

I also use a Studio Display via a Thunderbolt 4 dock and have no issues hot-plugging into it.

Absolutely love that there has been zero input from Apple support on this. Wait, no I don't. Please Geniuses... help.

I've "reported" this crash to Apple dozens of times....

Your computer was restarted because of a problem.

Problem Details and System Configuration:

SOCD report detected: (iBoot panic)

Apple M1 Max, 2021, maxed out, 14.4.1, same problem. Extremely frustrating, especially in class when you are connected and two dozen people are waiting for the machine to restart after it stops responding. Happens more when playing videos. Not so much with Keynote or simple screen sharing. Had it with different TVs, systems, directly connected and with a USB-C adapter that has HDMI. Thought it might be a hardware issue, but after reading all this I'm not sure anymore. Yes, please Apple, look into this properly!

Same problem on MBP M1 2021. Its driving me crazy. Have to keep re-installing the OS to get it properly working again. Black screen of the Mac and have to use the external screen as main screen to navigate. Then it works fine for a while after re-install, then just keeps crashing. Never had any issues before first using an external monitor.

Are there any settings that i can use which could help? Eg the different Presets in Display? Or different resolutions?

Apple shop ran diagnostics and found nothing. So just said it must be (i think) motherboard/logic board?! No attempt to actually find the problem
