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

I just had to erase my whole computer with a support tech because I decided to update to Sonoma last week. To say I’m irate would be an understatement. We tried everything, we couldn’t downgrade to Ventura without erasing everything. All my M2 customizations GONE. I don’t have time for this.

Hi, I have the same problem on a Macbook Pro 13 Intel Late 2018. After upgrading to Sonoma the Touch Bar doesn't work. It doesn't turn on. I checked everything, did various resets and tried all the various solutions but nothing. It worked perfectly before.

I noticed that the Touchbar process in the system monitor is not active. Is it possible to launch the process via terminal? I don't know what else to check

So I have the similar issue with strobing but mine is a bit different. I have a 2020 M1 Mac Pro. When I upgraded to Sonoma, the touchbar froze completely and I couldn't access any of the commands. However, when I jumped through all the recommended hoops, I ended up with a strobing touchbar that constantly sent commands to my computer. I had to change the settings because I can't turn it off. I have it set to window control, which is the least damaging because when it starts strobing, all it does is switch windows really fast.

Same Issue !! After updating to Sonoma: Macbook Pro (M1 2020) Touch Bar is not working , flickering green light all the time.Initially i thought it is hardware issue but after seeing the comment here everyone facing this issue after sonoma update.

@apple Please resolve this issue , this is not expected.

I am having this same issue since Sonoma. I was told there was a fix in the latest update, I updated and the issue still exists. The strobing touch bar happens when I open my MacBook from sleep, then 50% of the time it will glitch out and turn off the touch bar, 25% of the time it will work as normal then turn off randomly, and 25% of the time it will completely crash the OS and restart laptop (and every app I had open). I went back to Apple and am now being told its hardware. I am sure it is software related.

To be honest I couldn't find out if this is a software glitch, or physical damage. Sometimes laptop worked for several days without any issue, sometimes it didn't start up properly. Brought it to several repair shops, actually going back to Monterey fixed the problem, however some of my software did not work. Was ****** off so much, so decided to upgrade to m3 air 512 8. I guess you might be okay with previous macOS version.

I have the exact same model and I'm having the same issue. I hope they can fix it asap.

This happened to me once. Although nothing displayed, I could touch it and the functions still worked. A reboot made it work again.

Hello,

have same MBP model and same issue. TouBarServer process not running, ControlStrip one as well.

Have lataest Sonome version 14.2.1 and issue is still there.

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

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

sorry to hear that. i've too been bamboozled by an apple support tech over the phone & in store at the genius bar more times than i can count for this exact same issue concerning my touchbar so i can, unfortunately, relate firsthand.

as of rn, nope. unfortunately..... idk how much longer we'll all be in this same predicament. with this thread becoming longer and longer with users having the same issue & the radio silence on apple's end, it seems like we'll be here for a while :/

I have a Macbook Pro 2020 with an intel processor. After upgrading to MacOS Sonoma, my touch bar is lit up, but my volume buttons are not working which is very frustrating. I tried resetting the SMC (system management controller) Reset the SMC of your Mac - Apple Support, it did not work.
