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.

I can confirm that a big sur 11.0.1 upgrade including 427 firmware bricked a late 2013 macbook pro 15 inch. Upgrade completed, firmware update noted in sys. profiler, slept & rebooted fine but machine failed to power-up after being shutdown for a few days. Tried NVRAM and SMC resets but was stone dead; no backlight or fans only power changing from amber to green after a while. Eagerly awaiting an update to the recent firmware update that supposedly enabled wake from hibernation with upgraded NVMe drives in late 2013 models. Was hoping to get a bigger SSD after big sur but I'll have to hold off for now.

Julia, I hadn’t tried connecting an external monitor. There was no way to upgrade to 11.1, since my MacBook Pro couldn’t start up, other than to show a grey screen. I tried to start up in recovery mode, but there was no response to any key combinations.


I suspect that it’s the older MacBook Pros (2013-2014) that were really bricked by Big Sur, with little chance of recovery without some sort of hardware repair. Somehow, having an SD card in the slot during the upgrade was involved in many of those with bricked machines. My senior support guy said that the entire logic board could be corrupted by the upgrade.

Yes, this occurred in the US. But, neither the Apple Store or the authorized repair store could tell me why my Mac was stuck on a gray screen - just that it was toast and would need a logic board replacement. Apple had planned to start with the I/O board, and if needed replace the logic board. Apparently they are all out of replacement parts for these old units, and is (if you're persistent and lucky) replacing the computers.


So glad your 2018 is fixed at Apple's expense. I'm not sure I would go through the hassle of updating your 2013 MBP. It took 2 months of haranguing to receive my replacement. At least, it might be worth calling support to see what they suggest. Best of luck!

Two weeks after I got my 2015 15" MacBook Pro repaired back from Apple, I started getting hardware problems randomly. Sometimes the macbook would beep every 5 seconds with black screen. Sometimes powering it off and starting it up would fix it temporary, but the black screen with the beeps would come back a few times a day. A short beep every 5 sec means memory problems (RAM is soldered on the logic board on this mac). In the previous repair the logic board was replaced.

So luckily I got 90 days warranty on the initial repair and I brought it back to the Apple store. I was able to replicate the problem in front of the rep. Now waiting for it to get repaired again.

When this happened to me with my last MacBook Pro I could boot into safe mode but what was actually wrong w the hardware was my logic board was fried suddenly and caused the battery to swell, therefore I truly believe the Big Sur update bricked my MacBook Pro. I just got a brand new one shipped to me and it won’t even boot up. Weird coincidence right?

Have there been cases of this being repaired/replaced without Apple care? When I’ve contacted support they were rude to me, told me my 2016 MBP is “old” and compared it to a pizza, said I shouldn’t expect it to work forever. It bricked after auto updating itself to Big Sur. I have already taken it in and techs discovered the logic board failed and the battery swelled.

Happened to mine too. Kept rebooting and wouldn't do anything at all. Was told to take to Apple Store to get repaired. machine from April 2019, but purchased through the Refurbished program, so it was 1 month out of warranty.


They made me pay £90 to diagnose and repair. Called back 2 days later saying they switched it on and there was no fault with the machine. This after I tried to switch it on about 40 times, tried every recover mode under the sun, and spoke to Apple Tech support 4 times.


Obviously there is likely a BIOS bug on Big Sur, which Apple seems to hide from its customers, and judging by this thread, it is affecting many, many people. Felt like I was scammed out of £90.
