Failed to update macOS 12.3

An update: after few attempts, installed successfully, no special actions from my side, just let it sit until finished.

Here's a "me too!", but also a request:

There was mention of threads of reddit and other forums. Could we get links to some of those? It would spare us even more tedious web searching (I didn't see any of those, but found this one), and possibility of missing the important ones. It would be great to be able also to track/follow those other threads for progress.

12.3 update repeatedly fails with "iBoot panic" restart

Here are a couple:

Hope this helps.

I've tried three times to upgrade to 12.3 from MBP 2019. As I read comments here about logic board replacements, it occurs to me that the whole topboard (not sure that's the exact term) was replaced due to a faulty keyboard. Does anyone know if the logic board would have been replaced as part of that? I'm guessing it was.

Let's see how quickly apple fixes this.

Hello!

After the issue happened, I went to Apple store and they replaced a MLB for me.

But when I got it back, I still tried to upgrade (Cuz I didn’t realize the error was caused by the 12.3 at that time). It showed iBoot panic again after it failed.

Can I ask that will the error of iBoot panic damages my hardware permanently if I don’t upgrade one more time?

I really worried about it🙉🙉🙉

To be honest, this is frustrating because after a few weeks of waiting for my MacBook to be repaired I had to spent a few hours on trying to update it in vain.

After several attempts to update MacOS I stopped. When I have found this thread I realized I am not alone here. But now I still have Monterey 12.0.1 and it is so buggy that I am considering going to Apple to have my MacBook updated to any previous macOS version.

Initially, I was so happy to have my MacBook back because I also have iPad and wanted to use Universal Control but now I cannot even add my google mail accounts because of some 12.0.1 bag :-/

For a computer costing 3500 usd this is strange.

I have a MacBook Pro M1 Max and the same problem.

To cut to the chase, the quality and support is unacceptable.

My MacBook quit after about 1 1/2 months. The repair took a whole month, including replacing the LogicBoard twice (first replacement part defective). After I received the device back, the actual error (display failure) occurred again after 2 hours.

After that, Apple took an entire month to initiate the second repair (even though I am an Apple Care Plus customer).

After a total of 3 months I received my device back and now stumble as first about this update... Apple Support is informed, but they don't even get back to me anymore.

At a price of 5100 EUR, I would have expected something more. Would love to throw the device out the window, to where the money has gone.

It's been more than 1 week now, does this problem solved?

I got my MacBook Pro 16" coffee spilled 2 weeks ago and have everything (logic board, screen, Touch ID) replaced, the system version is 12.0.1.

First update to 12.3 failed but no "iBoot panic" error message. Attempts follow are also failed due to Network connection, then I found the "bricking" issue.

The 12.3 update is hanging there and I would appreciate if any updates to solve this issue, even Public Beta would do!

I just got mine after replacing the board and the touch ID key after two weeks in repair. This bricked mine and when I tried to upgrade it again, at least it only gave me the iBoot (Panic) error. Will be waiting for 12.3.1 soon.

PSA, if your Mac is critical or you haven’t fully backed up your data, hold off on the update!

I just tried it and… it did something wrong… it’s saying that I need to reinstall my Mac… Still trying to figure it out… just wanted to get this info out as quickly as possible.

Update:

Alright, that was the weirdest update process I've ever seen. During the update process started, it flashed the Apple logo repeatedly. It then went on to say that I needed to reinstall my Mac. So I went ahead and followed the prompts. After all that, it successfully installed 12.3.1 without any data loss, everything is still here.

Some background: Prior to this, my Mac was unable to update to 12.3. However, I did NOT have any logic board replacement. It just refused to update and kept saying "iBoot Panic".

So it seems that at least for a subset of people who where unable to update, 12.3.1 fixes the issue.

I would still highly recommend that you backup your data before trying it or, if you can't afford to be without your Mac, wait and see how it goes for other people.

MacBook Pro 2021 16", with logic board replaced. Replaced board with macOS 12.0.1, first attempt to 12.3 failed with iBoot Panic, unwilling to update again until 12.3.1.

Today I have tried to install the newest version, after several restarts, the system updates well and I also managed to backup my Mac with Time Machine.

Is there anyone that had an Intel Mac (with T2) that had the "bricking" issue without a replaced logic board?

Some days ago I updated my 2018 15" macbook pro (intel) to 12.3 and it couldn't open afterwards.

I could not revive it through DFU mode with the Apple Controller 2 because it was trying again to install 12.3 which could not boot with it and 12.2.1 was already unsigned.

I waited paitiently for this version and I did not restore it, to not erase data.

Do you think that if I try to revive it now it could work? (If 12.3.1 fixes the bricking issue in the Intel Macs too)

Yeah I will try even if it says that if fixes 2021 Macs, but I saw that the BridgeOS firmware for T2 was updated to a new version too so I hope they did something there too so it will be fixed.

Is there anyway to restore to 12.2.1? To find a whole MacOS version for Intel Macs?

Unfortunately there are no Apple Stores in Greece…
