MacBook Pro bricked after failed Big Sur update 😵 ⚰️

Hi Guys and Gals.


I saw that there was an update to Big Sur today so clicked update. It all downloaded fine and I clicked all the items to go ahead. It said it'd be a while so i stepped away from the computer. When i returned the screen was black - no status bar, no nothing, but I could tell the LED was on. Nothing would wake it up so I eventually held the power button to force a shutdown.


Now it won't boot. Tried SMC, PRAM, holding shift, option keys, recovery mode etc etc. Tried all many many times.


The only thing that happens is the LED for the screen turns on. So i can see it's slightly lit black, and the apple logo on the outside of the screen is lit up.


An automatic Catalina update destroyed my dads iMac a month or two back - resulting in a new SSD and a cracked screen from opening it up. And now my MacBook Pro (A1502) is now dead?? What's the deal?


At least it would boot into recovery mode - this one won't even get to the loading bar, or chime when i'm trying to reset the PRAM!


Any ideas? I've done everything I know to do. It was working just fine before the update, and now i'm kicking myself. Cant even do a restore from my backup!


😰

Just for info sharing, it was reported that unplugging the IO board (the one with the SD-Card, HDMI and USB port) allows Big Sur 11.0.x to further boot an "bricked" MacBook Pro Late 2013 - to finish its Big Sur 11.0.x OS install.


Once done, connecting an USB or Thunderbolt LAN adapter gets the MacBook Pro back connected to the Internet (because the unplugged IO board incl. also WiFi and BT - so not working so far anymore) and then allows Mac OSX Updater to search and update to latest Big Sur 11.1.x (Apple reported to avoid the "brick" issue with).


Once Big Sur 11.1.x update has finished, reconnecting the IO Board, the "brick" issue is solved without any hardware replacement needed.


So, wondering if it ever was/ is a bricked hardware, while this seems (at least for some) that it was/ is just Big Sur 11.0.x stuck the IO Board and therefore from booting, but Big Sur 11.1x update solve it quickly (by getting this installed with the method described above).


May this is helpful info (if not known by Apple Genius Bar Experts) and offers another way to "repair" an "bricked" MacBook Pro Late 2013 (or Mid 2014) by lower costs for the value of the users affected.

Mine took approx 40 mins to update, and it worked. I must admit, after reading all the horror stories in this forum I held my breath all the way through the update and numerous system restarts. It even went through a blank screen stage for about 5 mins, but came back and continued the install. Anyway, I'm pleased to announce my MBP Retina 13" Early 2015 is now on Big Sur 11.1

Some semi-good news on my Mid-2014 MacBook Pro - I finally got through to a very nice senior support person today that took me seriously, and was willing to research the issue. He found a document that discussed my very issue, and we went through a line of troubleshooting and questions that fit my problem to a T. It's being submitted to engineering. I'm hoping that someone will take pity on me and help repair or replace my computer. My problem is DEFINITELY related to the attempt to install Big Sur.

Hello Dana!

Glad to see your persistence pay-off and Apple provided the kind of support we love it for. Personally I feel tech issues are something that will always occur, it’s the way you’re supported that sets a brand reputation, so I was appalled by initial response from Apple to this Big Sur issue; Glad it got back on tracks! I got my 2018 MBP affected (it wouldn’t update, so needed a T2 chip firmware reset done for free in Authorized Tech shop) so I hold off any install on my old 2013 MBP. Cases like yours make more confident in going through now.


I’m sure the brand new M1 machine will soon make forget your ordeal!


PS: Could you please confurm your experience was in a US store?

So I made another appointment with Apple, went and delivered it and was called the next day that I would have to pick it up as all Apple retail stores in the DFW Texas area were going to shut down due to COVID.

The next option was a separate authorized repair store, so I delivered it and am waiting on their diagnostics. The rep at this store advised this was the third time the local Apple stores had temporarily closed due to COVID.

Thank you Dana, for your kind answer.

I’m considering to go trough the hassle because I use this as a backup machine, as I had to, during the whole month it took Apple to sort out the issue with my MBP. I also will use it to check Big Sur before install on my main MBP, however I’ll wait for a new more stable release.

Enjoy your new M1!

My heart sank when I saw this thread.


Like many others, I upgraded to Big Sur after being urged to do so by rather regular and irritating popup prompts. I was waiting for feedback on a live project, so I went for it.


My MacBook Pro (mid 2014), is now toast.


The one I rely on to make a living. In the middle of a web build for one of my few remaining loyal clients.


I cannot replace it.


I feel sick.


Why would Apple allow me to do this, months after the issue was clear?


They have totally let me down, with the worst possible timing.


I'm livid.
