MB Pro M1 Pro dead after 12.7 update

Had the same on iMac m1. But waited patient while the screen stayed petrifyingly black, and in the end it started.

I don't like this non descriptive black screens, and inconsistent user experience. Steve Jobs r.i.p. would never have accepted this behaviour of any Mac.

So what are we supposed to do now, DON'T update the official Apple updates because we can lose it all in a moment?

Hello,

It is not the first Monterey update for users. :)

I got the same problem, my MBP has never turned on after the flash process. It was powered and got its battery 100% full. Just the same than some other users, this 12.6.8 to 12.7 "security" update has just bricked my computer 10 days ago.

I really hope an official solution will be offered.

Best.

1. take working mac computer with macOS Monterey 12.7 or newer
2. install and launch apple configurator app
3. connect power cable to bricked mac.
4. take proper USB cable, it’s very important.
5. connect mac computers with the usb cable, plug usb cable to the proper USB port, it’s very important.
6. Press and hold the power button until the DFU icon appears in apple configurator app

Revive or restore a Mac with Apple silicon using Apple Configurator - Apple Support

does your mac play startup sound ?

“the apple reviving quest”

thank you for your reply.

In my case power cable was disconnected, fully charged battery. 

I know it’s bad practice. i was too tired 🍻 u know. before go to sleep i’ve launched update process and on the morning it was “surprise”

after brain storming 10 hours straight me and my friend got success finally.

so what was done:

1. we’ve got working macbook (intel) 13.6 ventura with installed Apple Configurator 
2. usb-c to usb-c “Samsung SSD” cable, the apple charging cable failed for the mission…
3. we’ve downloaded macOS 13.6 ventura .ipsw file from INTERNET for my MB Pro m1 pro 
4. we’ve connected both macs and put the 🧱 bricked one in recovery mode so the Configurator app showed DFU squared icon
5. we’ve dragged .ipsw file to the DFU icon and pressed REVIVE button

P.S.

by default the Configurator app very slowly downloaded ~14GiB macOS 14.0 Sonoma… and REVIVING process ended with error 

“The System cannot be restored on this device.

Failed to restore device in recovery mode, libusbrestore error: 21

[com.apple.MobileDevice.MobileRestore - 0x15 (21)1” 

we used at the moment apple charging cable…

well the macbook is working on macOS 12.7 Monterey now, but the firmware and recoveryOS i guess is 13.6 Ventura version, the macos update software menu is showing only the Sonoma update is available, there’s no Ventura option…

we’ve tried 12.6 ipsw file - fail of course.

12.7 file is not existing.

we’ve tried 13.5.2 file - success, but the macos update menu is still showing only Sonoma update option…

Thank you for your answer.

My Mac display the Apple logo and sound when I open it, then shut down. If I keep the touch id button pressed, it display a message under it. I release the button when the message change to enter into the config menu (I don't remember exactly the text) but then shut down.

When my MBP is connected to another Mac, Apple Configurator detect it, but the revive process is avorted (buserror 21). I can imagine it is not completly fried?

Reading the above solutions, I can understand that error is displayed if the process bellow is not properly followed?

Why I have done this update... Probably I had better to install Sonoma first. :(

I really hope Apple will do something, I have never encountered any problem with all my Mac since 1986.

Thank you for your kind support.

I have bought the official Apple USB-C to USB-C charging cable supposed to be power and data. (They have their own)

May be I have better, as you suggest, to do several temptatives by myself. Currently, my MBP is still at the Apple Store for a week.

This process is outlined very well. Thanks for sharing.

I did run through these steps and the configurator wanted to download and use newer updated software. I believe this was for Sonoma, however I am on Monterey and did not want to upgrade. So I did use an ipsw file from ipsw.me for 12.6 and dragged it onto the DFU icon, and clicked on Revive.

The revive still did not work for my Mac so I had to do the Restore which restored the MacBook to factory condition. All my data was gone. Then I had to restore from Time Machine Backup. Glad to have a backup in place!

I hope this 12.7 update does not knock out more MacBook's at work here as this was very time consuming and a terrible experience.

The Apple Store was finally able to restore my MBP M1 Pro, after some tries to reinit (no revive) and install Sonoma. Next, I have used my Time Machine backup to got my computer ready to use few hours later.

Thank you again to you and Apple for their kind support.

Hello! Is there any possibility to make this process WITHOUT wiping all the data from the computer?

It is quite annoying that this happens all of a sudden with an official Apple update, and you have to lose all you had in your MBP......

PS: the same happened to me
