M1 Macbook Pro Black screen

Has anyone found a solution to this yet? My screen did the exact same thing - just goes dark or blank. It displays the logo at startup and shows login screen for an instant before going dark again. External display connected works perfectly fine and no other issues except the MacBook screen not displaying information correctly. It works with startup options and displays all of that fine, just not when booted into login screen. Genius bar trieed to revise then restore, but no change. They say it's a hardware issue but it seems to be software related as evidence by the symptoms noted.

I believe that resetting NVRAM does not apply to Apple Silicon macs, at least not in the same way as it used to work. They do not use the same “hold this key combination” at startup options as Intel macs.

Startup options like recovery, or safe mode, are reached instead by pressing and holding the power button when starting from a shut down mac. Does it not even display anything then?

Having the same issue since the last security update. It’s the laptop screen only, if you’re attached to a second display in clamshell mode then it’s black, but opening the lid brings the external monitor to life, but keeps the laptop black.

This allows you to at least use the Apple menu to restart - which will fail - and then by selectively force quitting each app I think I’ve narrowed the culprit to Safari. Going to try avoiding it and see what happens.

Just posting in case this helps others.

"So many others"? It seems to me that if that were the case, there would have been an outcry here.

So, your mac turns black and you have to restart, is that it?

We need more information. Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

You said that sometimes it works, and at some point the screen goes black.

Obviously I meant to run the report when it does work. I may have misunderstood your problem, it seemed to me that when the issue occurs, you could restart your mac and it would then work. This does not mean that there is no problem - there certainly IS - but it means that you can run Etrecheck and post its report, so others (and not just me) could look into it and maybe spot some indication as to what is wrong.

If I misunderstood and you mean that the screen is permanently back - then either it does not even start, and you need to take it in to service, or it starts but shows no image. In that case, it is possible you might be able to use it if you attach an external display, as a temporary measure, to help further diagnose (and regain use of your mac, until the issue is resolved).

I don’t know when 13.4 comes out, of course, but there have been several betas alread, so hopefully it is not far off. One other possibility might be to install a current beta.

Large improvement from uninstalling World Clock Pro - I doubt it’s the app itself, but more likely some graphics calls it’s making, possibly for transparency 🤷‍♀️
