M1 macbook pro fails to upgrade to Sequoia (15.4).

Cleared out space (300GB available).

Find My was not turned on.

Start of error log:

I am having the exact same issue. Macbook Air M1 2020 fails to upgrade to 15.4. Upgrade from 13 to 14 worked via the Appstore, but then onwards to 15 does not. Tried safemode, etc, Apple support walked me through some steps (e.g. removal of VPN software, new admin account, renew macOS installation, ...) but so far without a solution. Current suggestion is to erase the Mac, but I am hesitant.

I made some small progress on this following my reply.


To recap:


I had an upgrade to Sequoia flagged for my M1 MacBook Pro, which was running Ventura.

In the list of other upgrade items, the Sonoma upgrade was listed (as well as Safari).

I ran the Safari then the Sonoma upgrade, and it appeared to work.

I rebooted, then ran the Sequoia upgrade, which was the only upgrade now available.

This appeared to work, but once I logged in I received an error message. I opened the associated text file:


panic(cpu 0 caller 0x0): t6000dart 0xfffffdf034198d70 (dart-dispext0): Can't ignore lock validation @t6000dart.c:437

Debugger message: panic

etc.


I read the comments on Apple community and other support sites, and worked through the suggested solutions:


I rebooted and switched off “Find My Mac” and tried again.

This failed the same way.

I rebooted into Safe Mode, and tried the upgrade again in Safe Mode.

This failed the same way.

I noticed that the Mac wasn’t running Sonoma, but had rolled back to Ventura.

I rebooted and logged in using a blank account (I call “admin"), which is not connected to an Apple ID, and ran the upgrade to Sequoia again (the Sonoma upgrade no longer there).

This failed the same way.


I contacted Apple support.


I rebooted and logged back in as myself, and tried reinstalling the operating system: only Ventura was available.

This worked without problems.

I rebooted and ran the only upgrade now available to me under Upgrades: Sequoia.

This failed the same way.


I rebooted, and went to the app store and downloaded Sonoma from there, and ran the installation.

This worked without problems, and I checked that I was running Sonoma.

I rebooted, and went to the app store and downloaded Sequioa from there, ran the upgrade.

This failed the same way.

Rebooted, checked "Find My" was still turned off, and tried in Safe Mode.

Still failed the same way.


So, I am now on Sonoma, but Sonoma will not upgrade to Sequoia either, with the same error message.

unplug all non-essential peripherals when testing...


reboot into SafeBoot mode and try again your update:

Download it on another Mac or download a Sequoia installer from the internet (I personally don't recommend trying download it from the internet, because the source can be insecure) and make a bootable drive (like a pen): Create a bootable installer for macOS - Apple Support. If this don't work, consider doing a Time Machine backup and erasing the Mac.

I've the same problem with M1 MacBook Pro.

So yesterday I've downloaded the update from macOS 15.3.2

After the download from Settings it starts to update.


After that it shows a window where it ask for my FileVault password (never seen before).

So, I've inserted it.


After that, only boot loop. No log given.

So, I've seen using Terminal that in Macintosh HD - Data there are all my folders and files.


I've tried:

  • Restarting in Safe Mode: same problem
  • Create a macOS 15.4 update from USB stick created from another mac: after install, it keeps bootlooping and no log provided.
  • Using S.O.S. from Disk Utility it shows a lot of warnings on snapshots.
  • Restore window shows "Install Monterey" that is four years old.


So, now, how can I do?


Since this morning I'm with Apple Support but no guidelines to solve the problem.


I don't want to loose all my data for a minor update (I've done a cp operation using Terminal on a external SSD but probably I've missed some path/folder to backup).
