Making an account just to say I also had this on my 2023 M2 Pro Macbook Pro 14 inch. I set the update downloading and when I came back, my machine was completely dead with no signs of life other than Magsafe showing orange and then green once fully charged.
Used A Mac Mini at work with apple config to revive - just some notes though i'd like to add for more detail for anyone who might need it, I was going off 3 different sets of notes to get enough detail for me.
1) get the IPSW file for 26.3.1 from here
https://updates.cdn-apple.com/2026W...1973/UniversalMac_26.3.1_25D2128_Restore.ipsw
2) For DFU mode - I found a comment on reddit that had different instructions from Apple but apparently were more reliable. I got into DFU mode on my first try. Make sure the mac is not connected to anything first.
2.1 Press and hold the power button (Touch ID). (Make sure your mac is fully charged if it is a Macbook)
2.2 Immediately hold down these keys as well for 10 seconds:
Left Control, Left Option, Right Shift.
2.3 After 10 seconds, release the keys but continue to hold the power button (Touch ID) for another 8 seconds.
2.4 Plug in USB C cable into DFU port and connect it to your Mac with Apple configurator.
2.5 Drag the IPSW directly onto the Mac in the list on apple config, and click revive.
2.6 Wait. It took about 3-5 minutes, My mac then booted into recovery, I entered my password and it rebooted. The first reboot failed so I manually clicked Macintosh HD, entered my password again and then it worked.
