Big Sur - Black Screen After Update?

I have a 2014 Macbook Pro 13" Retina that I have installed the new Big Sur OS, I did make sure there was enough space to install beforehand which there was.


I now have a mac that is powered up (apple logo on lid is lit up) but the screen is black and I have no idea what to do?


I don't know of it is still installing the OS or if its locked or something else. I set off the install and just left the laptop to do it's thing


Any help would be greatly appreciated.

The solution I have found is to hold down Option when restarting. This will came up with available hard drives and "Big Sur" (The bootable partition that has been created for the upgrade). Select your main hard drive and it should boot up normally. Not that this only worked with my Apple keyboard - my third party keyboard wasn't recognised by OSX until later.


Hopefully this works for you.

That was a question I had submitted; whether BIG SUR was ready for release or not?

As CATALINA was such a mess--AND for me-it still is! i want to get rid of IT!

However, not IF IT IS STILL "NOT FINISHED" as Catalina, which gave me ALL KINDS OF PROBLEMS & STILL DOES!

SO VERY SORRY I "LEFT" MOJAVE!

"NEW is NOT always BETTER" & should know to leave "things well enough ALONE"!

My device had been just repaired & worked perfectly UNTIL THE DOWNLOAD OF CATALINA! A whole 2 weeks!

Thanks for your reply BUT still am very nervous!

APPLE suspended me when CATALINA was first installed on my DEVICE---as Catalina was RELEASE before IT was "READY"!

ALL I DID WAS ASK WHAT HAPPENED TO SCREEN SHOTS!

BUT THEN received about 87 NEW COMPLAINTS via OUTLOOK. NO one else was suspended & I was told

I will be permanently SUSPENDED--reason---UNKNOWN!

"AFRAID TO ROCK the BOAT w/APPLE" of EVERY ONE ELSE'S COMPLAINTS/CONCERNS,

though I did post a QUESTION of my own~asking

OTHERS' if IT is ready OR still "glitches"? AS in CATALINA...WHICH STILL CAUSES ME PROBLEMS!

Which obviously [like your question] THERE STILL ARE!

THANKS so much, [afraid I will never see these questions answered], as APPLE told me I would be "permanently" REMOVED from this community, to ask a QUESTION!

First, elmarklimov, do you have a verified hardware failure, or simply a symptom that you, and some others, interpret as such?


Second, even if you do have a verified hardware failure, did you perform a clean install of the Big Sur major Operating System (OS) upgrade, or did you treat the upgrade the way you might treat an update? (Admittedly, I didn’t go the clean install route, but I did make sure I had a full backup. [Of course, my machine is still under warranty.] I know others that routinely perform clean installs of all upgrades [vs. updates]: it’s simply what their experiences have taught them.)


In this latter case, there are too many compounding issues that could have occurred to contribute to the hardware failure. (This is to not even mention the boarder-line hardware issue, which is ever present with anything short of pristine hardware.)


Ending on a positive note, those that didn’t have any actual hardware failures, have found that they can (with care and some skill) install Big Sur version 11.1, and regain a fully functioning machine!

Thanks for the reply. A couple things:


  • Analogies don't expire so it doesn't matter how old it is.
  • Analogies are poor parables of the truth. If you feel the need to use an analogy then you don't understand it well enough yourself to explain it clearly.


Take it from someone who used to use analogies all the time and finally realized they don't help, as you can see from all the confused replies.

Like I wrote, NewJohnny:

«If you understand the issues with aging hardware, then you have no need for an analogy.»


Unfortunately, this is, often, a matter of experience.


Those with too little related experience, can have difficulty understanding the concept, unfortunately.


(I’ve especially seen this with software [only] engineers. After all, they only consider hardware to be the unchanging “stage” upon which their software runs.)

So my problem is similar but a little different. I am using a Late 2016 MBP and I had the initial version of Big Sur installed and working properly with no hiccups. Then a few days ago I installed Big Sur 11.1 and this morning I get the black screen. I plugged up an external display and it works fine like normal, so it is my main Retina display that isn’t working I guess? Should I uninstall 11.1 and try reinstalling?

For me it did show as an “update” and now I have a brick instead of a working laptop.

While it did show up on the Update Panel, it was labeled an upgrade.


Unfortunately, I can understand people not noticing such a seemingly minor detail.


(Of course. Once one installs Big Sur, all subsequent updates are updates to Big Sur.)
