Thanks for that. I can confirm, following these steps I was able to revive my machine with Sonoma (Edit: Without data loss).Just an FYI, if you are bricked doing the upgrade to 12.7.1 or 13.6.1, the process to recover without losing data is very detailed. (Note: I have not performed this myself, but I have confirmed with out MacAdmins dealing with it)
1) Put the affected computer in to DFU mode.
2) Revive the computer using Apple Configurator and an IPSW for macOS Sonoma. To choose a specific IPSW, drag the IPSW to the DFU icon in Apple Configurator. Do NOT try and use an IPSW earlier than the version you tried to upgrade to.
3) Once the revive is complete the computer will reboot to boot menu. Do NOT select Macintosh HD, instead select Options to boot to recovery
4) Select the option to reinstall macOS Sonoma on your computer. Don't erase the drive first. Reinstall will not wipe user data.
This should work, however, you will be upgraded to macOS Sonoma.
It would be much easier if Apple would release IPSWs for 13.6.1 & 12.7.1. But they don't typically release new IPSWs for older OS.
Exactly my thoughts. It's a new low, for sure...I have bricked four MacBook Pros in under two weeks thanks to the 12.7 update (on my M1 16 inch MacBook Pro) and the 13.6 update on three new M2 16 inch MBP’s. On ONLY the most recent one, I was successfully able to do a “revive” in DFU mode, which installed Sonoma but did not erase any of my data. In all cases, ProMotion was disabled and the screens were running at 60Hz.
In over three decades of using Macs for audio production and DJ-ing, I have never experienced anything approaching this level of insanity. Clearly there are very serious QA issues in Apple’s system software testing for something like this to be released to the public. Certainly a big disincentive to install OS updates knowing the computer may be bricked (and maybe or maybe not recoverable with DFU mode).

Maybe you clicked update, and than postponed restart and restarted it on that later day ?Is anyone else seeing these “bricking” issues NOT happen immediately after doing the Mac OS updates, but crop up a few days later? That, assuming my own “MacBook Pro Bricking” issues are the same as what’s being discussed in this thread, is what I’ve been experiencing.
My whole odyssey started almost two weeks ago, with an 18-month-old M1 16” MBP. I had, a few days previously, run the latest Mac OS Monterey updates….used the machine for the following few days with no apparent problems…then experienced the “bricking”.
I wish I could tell you that’s what happened, because it would seem to make much more sense than my actual experiences of the last two weeks, but definitely not. In my latest case (the brand new M2 MBP that I was able to “revive” in DFU mode and is now running Sonoma 14.1), I believe three full days (with some shutdown/startup cycles after the OS update) had elapsed before the computer experienced the power-on-to-black-screen issue.Maybe you clicked update, and than postponed restart and restarted it on that later day ?
Are you ***** kidding me?The trigger for this problem appears to be that Promotion is turned off in Display Settings before the update is applied. Unfortunately there is no real easy fix for the black screen once it happens aside from restoring the system.
Which also begs the question, why does the "Revive" option, which I thought was supposed to fix the firmware, not work? There's multiple levels of fail here from Apple...Above would not work I think, the t2 firmware or whatever is messed up at that point, as evidenced by the fact that booting into recovery fails.
New finding: beeing on 13.6.1, disabled ProMotion, restart Macbook and it is bricked ! So it is not just during update … :/ !!!!!!!!!!!!!!!!!!!!
I am sure that you have changed this setting after update and got bricked when restarted Mac next timeThis *might* explain my experiences with the three new M2 MBP’s seeming to have a delayed onset of the “bricking” issues after updating their out-of-box Mac OS versions from 13.5 to 13.6. I don’t think it fully explains the first “bricking” experience I had with my M1 16-inch MBP a couple weeks ago. I’m almost certain I didn’t change any display settings on that, just updated it’s installed Monterey OS to the latest version. I then used it for several days without apparent issue, then when powering up one time it “bricked” with the black screen.

I can confirm this: one out of two of my 2021 M1 MBPs bricked during update to 12.7, with the described symptoms. The other one survived; both were set to 60Hz. The one which failed was a NOS machine, just taken into operation and set up hours before. The other one is still going strong - I did several reboots on this one, to confirm it won't die at the next reboot following the upgrade, too (a phenomenon others have reported). Conclusion: while this bug seems not to hit every time the screen refresh rate is set to a fixed value, it is definitely present in 12.7, too - and Apple is 'scary slow' in responding to their 'scary bad' code quality!
- Possibly: macOS Monterey 12.7 (unconfirmed) (confirmed unaffected, 12.7 uses 13.6 firmware apparently? weird.)
12.7 and 12.7.1 are also affected this is where first time happened to me going from 12.6 to 12.7 !
Do you connect either of these MacBook Pros to external displays? It seems possible that there’s some connection with use of external displays.I can confirm this: one out of two of my 2021 M1 MBPs bricked during update to 12.7, with the described symptoms.

Both machines were connected to nothing but the original Apple MagSafe power supply at the time of the upgrade, and never used with external displays.Do you connect either of these MacBook Pros to external displays? It seems possible that there’s some connection with use of external displays.
Very disquieting that there seems to be certain “random elements” in all of this.Both machines were connected to nothing but the original Apple MagSafe power supply at the time of the upgrade, and never used with external displays.
