Unable to install macOS Sequoia update 15.4 on my MacBook Pro

I’ve done literally everything. 15.4 doesn’t work on my M1 Pro so I just downloaded 15.3.2 from MrMacintosh website which installed without any hassle and works great.

I’ve heard that 15.5 is underway so hopefully that will solve this issue. I’ll just wait for 15.5 now and skip 15.4 I have already wasted 3 days.

Plus I donot know why apple is not talking about this issue which is so frustrating.

Do note that I wasn't able to create a boot disk from this.

So my end-to-end operation is:

1. Recover from my boot disk (14.7.5 Sonoma)
2. Get the system into a working state
3. Restore from Time Machine snapshot I took the other day (at 15.3.2 Sequoia)
4. Run the command to grab the installer for 15.3.2
5. Install 15.3.2 Sequoia
6. Reboot
7. Recovered

Hopefully this end-to-end recovery process helps someone; I wanted to ensure I'd not led anyone astray with incomplete or incorrect instructions earlier--nope, those were correct.

There is nothing wrong with 15.4 once it's installed. The problem lies with the installation process on some M1 based machines. The 'DFU restore' is definitely the best way to solve this problem as it also updates the base recovery image on the machine.

Pls read the post thoroughly...

15.4 is EXACTLY the reason causing all this craps...

If your Mac is working fine, don't do anything.

If you are already facing the same issue, DFU/USB install a 15.3.2

BTW, I did a DFU Restore, couldn't boot.

Your problem may have nothing to do with 15.4.1.

Follow the instructions for resetting the SMC on your Mac: Reset the SMC of your Mac - Apple Support

If these don't do the trick, your only reasonable option is to bring the laptop and charger to an Apple Store for analysis.

Yes

So what does the Terminal command below report ? ?

softwareupdate --fetch-full-installer --full-installer-version 15.4

I already got back my mac mini form genius bar,I try to create a new ssd to make a 15.4 full install, and then transfer my old ssd data, it work!

After spending a lot of time, the conclusion is:

15.4 is the problem.

For anyone is encountering this issue, install 15.3.2 and wait for next update.

Do not waste anytime on this...

@ren1018 If you have data that needs to be recovered/backed up go for the ‘revive’ and see if it works. If you already have a backup I would save the time and do the ‘restore’.

The funny thing is that if you click 'download,' MacOs shows 15.4 in the process of downloading, but I'm not sure if I want to do a full re-installation on a corporate-managed machine. Will it preserve all of my files and settings? I just wanted to update as usual, but it constantly gives me that error. I have no clue how to fix it. ( I tried literally everything.)

" not sure if I want to do a full re-installation on a corporate-managed machine "

A Full re-installation ?

What do you mean by Full Re-installation ?

Corporate - Managed machine ?

Check with the Company IT Department

It is Their Machine to support and to have Tested if this will or will Not work

Dreadful experience here:

Facing the same issue and it completely damaged my system .

I had the same message as OP posted, and at some point my laptop was able to restart , proceeded with the update but failed.

At this Point, I was unable to start the laptop anymore, I was stuck in a boot loop forever.

• I tried recovery mode to run some diagnose and fix but amongst all the options available Only Reinstall Sonoma was possible.
• My current Volume was marked as "unable to downgrade", so I had to create a new disk and install Sonoma there.
• For 24 hours, now I have been installing Sonoma, upgrading to Sequoia 15.3.2 and moving ALL my Data over ! Stressful and losing time unable to work !
• At this point , I have 2 systems running 15.3.2, only one is bootable though.
• The new OS is still proposing to update every once in a while but unable to upgrade to 15.4 .
• I WILL NOT risk to update it before Apple fix it for sure.

Same problem here.

M1 mac mini running 14.7.5.

The only mildly unusual things this mac mini are that (1) it's using an Apple brand USBC to VGA adapter plugged into a KVM switch connected to a VGA monitor, and (2) and I'm screen sharing using ARD.

Try using Software Update

Update to 15.4 using the Software Update Control panel: fails with a kernel panic, reboots back in 14.7.5.

Repeated: happened again.

Try with Full Installer

• Downloaded the full "Install macOS Sequoia" installer app (15GB) by going to the Mac App Store, searching for Sequoia, and clicking the "Get" button to download it. (I downloaded on another mac (M4), then copied the file over to the ~/Downloads folder using ARD, then moved it to /Applications)
• Launch the full installer app: the installer runs, asks to Restart, then reboots. Progress bar comes up saying "about 11 minutes", then 5 minutes, then 3 minutes.
• End result: it reboots back in 14.7.5 with another kernel panic:

Has anyone on Sonoma WITHOUT any luck installing 15.4 attempted to pull a LATER version of Sequoia utilizing the below terminal command provided earlier in the thread? Is this possible? Assuming one has the time, resources and know how to get an os back onto the system, etc.

softwareupdate --fetch-full-installer --full-installer-version 15.32

Good morning, DLZab. FWIW, I was able to find a client willing to test "fetching" full installer 15.32 with SUCCESS last night. Client was running Sonoma 14.7.5 on an M1 having no success upgrading to 15.4 resulting in crash diag: "panic(cpu 6 caller 0x0): t6000dart 0xfffffdf055505ae0 (dart-dispext1): Can't ignore lock validation @t6000dart.c:437

Debugger message: panic

Memory ID: 0x6, etc."

Thought it was just me but it seems it's the same problem for everyone else. Tried everything to 'upgrade' from Sonoma to Sequoia on my MacBook Air M1 but although it goes through all the motions of seemingly installing Sequoia it always ends up with Sonoma. Have tried installing from the update in software updates, from the full app and also from a USB stick. All fail. A waste of time and I think having read some horror stories in this thread that it really is not worth persevering in case I brick the laptop. Apple needs to do something about this and PDQ.
