Sonoma: Macbook Pro (M1 2020) Touch Bar is not working after update (Flickers during restart then once logged in, it disappears)

I upgraded to Sonoma yesterday on my Macbook Pro (M1 2020). Touch Bar keeps flickering during startup (looks like it is glitching) then once logged in, it disappears. What could be a issue?

Tried safe mode, tried sudo pkill from terminal, and everything else online.


Could this be a hardware failure because of Sonoma?




MacBook Pro 13″, macOS 11.1

I had the same issue right after updating my system to Sonoma. Right after updating my touchbar was black with no icons or lights. I continuously restarted and did a couple of hard resets on the computer. The touchbar then finally came back on and worked. However since the upgrade, sometimes the touchbar will disappear again (going black with no icons) when I restart my computer. I then have to do a couple of restarts and hard resets for the touchbar to reappear. Hope they can fix it ASAP.

I tried everything possible and nothing worked. Here's a video to show you how it flickers.

The thing is, once I log in, it disappears, however the touchbar is still functional. When I am logged in, I can still click on things (volume for example, mute...etc) but it is not showing me anything. This has never happened before.

I upgraded to Sonoma and experienced Touch Bar strobing after upgrade. I reinstalled it again thinking I had a bad build. After fresh install, Touch Bar strobed until it went dark. Now I don't have an escape key which is irritating. I've tried everything online to fix it to no avail. In addition my activity monitor crashes every time I open it!

i'm experiencing the exact same problem! i've been trying to return my computer back to ventura (or whichever software it was on before sonoma) this is very very very infuriating these devices cost WAY too much money (even more if you have apple care) just for simple functions to not be working properly / as promised when we users update to the newest software

Try this to reset the SMC of your Mac

Make sure that your Mac is plugged into power, then take one of these actions. 

  • Restart: Choose Apple menu  > Restart.
  • Or shut down: Choose Apple menu  > Shut Down. Then press the power button on your Mac to turn it on again.



If this is not working, please boot your Mac in the safe mode to see if the issue persist


  1. On your Mac, choose Apple menu  > Shut Down.
  2. Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
  3. Press and hold the power button on your Mac until “Loading startup options” appears.
  4. Select a volume.
  5. Press and hold the Shift key, then click Continue in Safe Mode.
  6. The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.


If it does not persist in the safe mode, it is caused by an external piece of software, you might want to evaluate the software you've installed on your Mac.


For your question if this is a hardware error caused by Sonoma, I want to stress that correlation is not always causality. What I want to say with that is that the error might have occurred after updating to Sonona, it is not yet proven that it is Caused by the update to Sonoma.

Hey,


Did you already find a solution?

So my Touch Bar was full of blue spots a few days ago and now it turned completely black after the update.

It is still functioning when I touch it but just the lightning is not working at all, completely black :(

So annoyed and stressed at the moment haha! Should I go to an Apple Store or something?


Kind regards,

Jhamel

apparently, i have an apple silicon computer w/ an "apple m2"' chip & the only instructions of resetting the smc is to just simply restart the computer ....which doesn’t work & has never worked for the touch bar issue. i've also gone to multiple genius bars at multiple different apple store locations just to be gaslit love that for me
