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.

Hold down Option while restarting and it will come up with your bootable drives. Manually select your normal hard drive rather than the Big Sur installation partition.
Alternatively hold down Command + R while booting up to enter recovery mode and reinstall OSX.
With either option. Delete the Big Sur installer from you Applications folder and try redownloading and installing from the app store.
And, I would recommending backing up when possible in that process. There was no problem with the hard drive in my case.
I had the same problem after upgrade to big sur on MacBook Air 2017. I tries a SMC reset but it didn’t work.
However the boot in safe mode suggestion by holding down Shift all the way till you reach the final stages (past a safe boot query screen) has fixed my problem and the laptop seems to be working normally now.
A friend of mine Restarted in safe mode (hold shift) and he was able to get to the desktop

Below worked for me (Macbook air 13-inch - Mid-2013) as a temporary fix, until i shut down and restart, i have to repeat this again -
1) Power off your mac by pressing power button for 10 seconds
2) Start recovery mode by pressing cmd + R button on powering up
3) Once we enter into the recovery mode, restart using the menu at the top, macos now reboots without any issue
Important that you don't restart or shut down the system again, in which case you have to repeat the same steps again.
Cured my black screen of death after the latest software update.
I have an external monitor and hooked it up to my laptop via Thunderport and HDMI. Although my MBP screen was black, it worked on the monitor.
I thankfully had a recent TimeMachine backup. I brought that up on my external drive, updated to the last item, sorry, can’t remember the name. The one that wasn’t applications, or my profile. Whatever the last item was. It was a small file, so it was fast.
Once that was reinstalled on my laptop, everything worked again.
My MBP is an early 2011.
I found this official help from apple https://support.apple.com/de-de/HT211242
Same problem with a MacBook Air 2020- can't get the built-in display to work after installing Big Sur twice. An external Thunderbolt LG display is working connected through an Apple branded USB-C to Thunderbolt adapter so maybe you might try an external display.
You can solve the problem using a bootable usb with the previous MacOs, insert the usb, turn on the laptop and immediately press abd hold option key until de Boot options appear, the select the USB drive and follow the instructions.
when the process finished my laptop startup with Big Sur and Ok.
I have been using Macs from their inception. Bug Sur is without a doubt the worst OS that Apple has ever made (when it comes to upgrading and making a bootable hard drive). When this black screen issue happened to me the only way that I could fix it was to format the hard drive, and install the OS (11.2) from scratch. Make sure you've copied all your files before you format anything. I would use CCC for this. You can also use Configurator 2 to fix MacBooks that get "stuck" if you have another MacBook to connect to the stuck MacBook.
Same problem. Macbook pro mid 2014, installing Big Sur, black screen. In the official service they told me that it is a I/O board problem. It is clear it is a problem due to the update.
You did not say which version of Big Sur you used.
For older MacBooks it should only be 11.1, not 11.01.
Seems like your LCD burned out, or your GPU did, or your install is corrupted, try recovery mode and reinstalling big sur

I am having this issue and went to genius bar in apple store in Dubai who told me that i/o board is damaged and needs replacement. They are charging me ~AED 465 tax for damage their OS update caused. How is that fair?
