Failed to update macOS 12.3

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.

I've been through TWO logic boards. The first one died after my Touch key died. Took it to Apple store here in Sydney and they diagnosed a hardware problem requiring replacement of the board. (I got my MacBook Pro -- an M1-- only in mid-November.)

They replaced the board. I went got the repaired machine and took it home, excited I would have a laptop after almost a month of hassles. I tried downloading the 12.3 update and got the dreaded circle with an exclamation mark inside and tried to restore the system. NO luck. Took it back to the Apple Store. They couldn't fix it so replaced the SECOND logic board (if I wanted to be snotty, I'd note this was the THIRD logic board in this clamshell....) Not knowing about the problems with 12.3 I tried downloading it to keep my machine up to date. The laptop just cycles through over and over. At least it hasn't destroyed THIS logic board! But it's impossible to find out what's going on from Apple. I don't know if there is a problem with the plant making the logic boards for the new MacBook Pros, but something seems pretty weird here. In 25 years of relying on Apple products I've never had a problem like this.

ONE NOTE FOR APPLE -- you've got to consider having a single global policy for repair of your kit. I bought my laptop online in the US and no one in Apple here in Australia would agree to replace my machine, which didn't work at all. They noted different countries have different laws -- blah blah blah -- but no company is going to get into legal trouble by being TOO generous and thoughtful in helping their customers. I've logged more than a full week of time (including travel) trying to get these problems resolved. If Apple's policy had allowed I could have spent an hour or so (not including travel time) getting a new laptop each time -- as Australian law allows since the gear simply didn't work -- and walked out. Instead, Apple spent several thousand dollars having workers buy and replace the logic boards. And making this customer spend hours and hours on the phone and in two different Apple stores to find out what was going on and how Apple would fix it. And you left this Apple customer, stockholder (long time) and fan feeling very uneasy about my future relationship with the company.

Fix the upgrade please. Tell us what's happening with it. And produce a decent global replacement policy that will garner you nothing but praise, consumer loyalty and probably sell more kit.

I have same problem with my MacBook Pro 16inch 2021 M1 Pro. I bought computer with a faulty fan probably the motherboard was replaced during the repair. Anyway, after update to 12.3 the computer went to repair again - black screen and blinking apple.

Yesterday came back from repair, everything works fine but I have ver. 12.0.1 again and I'm scared to get update.

I assume I have to wait to 12.4 right?

I have been using apple hardware for many years, I started from Tiger ;) I don't remember such a serious problem like this one.

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.

My MacBook Pro (16-inch, 2021) was yet another victim of a coffee spill (someone else's!) and had almost every component replaced (including the main logic board) when it was repaired. I saw the news about macOS 12.3 failing to install on these models if the logic board had been replaced, before I had time to install that update, so I did not even try, and waited to hear further news.

With macOS 12.3.1 mentioning an install problem had been fixed, I decided to risk it. After doing two backups, I updated from macOS 12.2.1 to 12.3.1 via Software Update. Worked just like a normal update, no strange problems at all.

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…

Thank you for the answer.

It can’t be put in recovery mode. It doesn’t boot up. It is like is dead. (Because I think the T2 BridgeOS firmware is corrupted)

The only way I can communicate with it is with Apple Controller 2 through DFU mode with another Mac.

So I will try to revive it through that way and let it download 12.3.1 and see how that goes!

Ok if nothing works It would be a good a idea to create a USB installer, but if it is in the same state, it won’t recognize it.

Welcome to Apple Roulette!!! I have 2019 MBP with a new logic board thanks to shoddy engineering by Apple and their need to replace the entire top module due to a space bar issue.

I've waited for 12.3.1 after going through cycles of trying to update to 12.3. I figured Apple must've fixed the problems because, well Apple. Nope. After 30 minutes of appearing to update, the machine restarted and I'm still on 12.2.1.

My advice, do not update to 12.3.1 until we get clarification from Apple (put on a pot of coffee, based on Apple's lack of communication on the bricking issues of 12.3, we ain't gonna' hear nothing from them).

I don't remember a screwup this bad from Apple and I've been on Macs for years.

Imagine paying the prices we pay for MacBooks and being afraid to update them accompanied by Apple's utter silence on this issue.

Crap.

Unfortunately the Mac could not be revived. It would enter the same cycle like 12.3 - not installing it.

But, I ended up restoring it (losing all data - good thing is I had all important things on backup but I lost some not important stuff) and I installed 12.3.1 - all through DFU Mode - and thankfully is now working.

Apple Support wanted to have my logic board replaced (with me paying it), thank God I waited for the next version and didn't do it. It is unbelievable they don't even inform their Support and Stores and didn't even give a heads up to people..

Unable to upgrade beyond macOS Monterey 12.2 tried numerous times to each notice from Apple. Completes the download and states unable, please try again. Check your internet connection. No luck with 12.3.1, 12.3, and last try 12.4. I pay for and receive 80 mbps. I give up. The downloads were in the sequence noted all offered by Apple updates.

Apple used to be reliable. I am having my doubts.

4 tries this morning. Same error message. Only my Mac Mini connected directly to the modem router. Download every time, gets to last 5 minutes and the screen shot appears.

frustrated. Thanks for the positive thoughts, but no luck.

I can’t see it either. But the release notes say that they fixed something related to Macs not updating to 12.3.
