macOS Big Sur Graphical Glitches: Black Wallpaper, Black Menu Bar
Are you experiencing graphical glitches in macOS Big Sur 11.1? Is the wallpaper unexpectedly disappearing and a black background is displayed instead? While this graphical issue is ongoing, right-click menus for apps available in the Dock are also displaying an ugly background with a gray / greenish tint!
How To Fix Black Wallpaper Bug
1. Restart Mac
A Mac restart fixes the problem, but it’s only temporary because the wallpaper bug unexpectedly reappears later on. We’re currently looking for other ways to fix it.
2. Switch Between Light / Dark Mode
Open System Preferences, tap on General and switch between Light and Dark mode to see if this will bring back the wallpaper and stop the display glitch. Does it work?

Other macOS Big Sur Graphical Glitches
1. Fix Black Menu Bar
Is your menu bar black in macOS Big Sur although Dark Mode is disabled?
No worries, this isn’t a bug. The Menu Bar color is influenced, by default, by your current wallpaper. Try changing the the desktop background and you’ll notice that the menu bar changes its color accordingly.
Tip: If you want to keep your menu bar to display in grey (Light Mode), or black (Dark Mode), without changing with the wallpaper, you have to enable the Reduce Transparency setting in: System Preferences -> Accessibility -> Display -> Reduce Transparency.
2. Pink Screen On Shutdown
Is your Mac display also turning pink, for a couple of seconds, while shutting down macOS Big Sur?

Thanks for reporting. What macOS Big Sur version are you running? Does this happen after a specific update or ever since you bought the notebook?
hello, I’m having the pink screen issue with a newly bought MacBook Pro 13′ (intel-chip). I installed Vagrant and Virtual Box on the computer, and when I clicked “restart” this pink screen showed up. I went to the Apple store to exchange a second MBP and the same issue happened. I even erased the whole computer (after uninstalling Vagrant and Virtual Box) and reinstalled the macOS. And the pink screen still showed up on “restart”. However, when I “shutdown” the computer and manually turn it on again, it works just fine. It only happens at restart. Why is that? How can I fix it? Is it a problem with the softwares I installed? Should I do another exchange? thanks!
Thanks for your report. By the looks of it one of the two software is causing the pink screen issue. macOS Big Sur is known to trigger bugs and glitches with third party apps. I would recommend you to also ask Apple support about it.
P.S.: Have you tried to restart in safe mode:
– Click the Apple logo, available in the top-left corner of the screen.
-> Go for Shut Down… and wait between 15-30 seconds.
->Turn your Mac back On and immediately press & hold the Shift key.
-> Release Shift after the log-in interface is loaded. Provide your Password.
Does the pink screen issue also show up in safe mode?
Yes I am having this black wallpaper bug! It’s so annoying – every few seconds it flashes to black and the menu bar disappears. Also when the usual screen returns all my minimized windows expand. Very frustrating.
Thanks for confirming this Genevieve. Does a restart fix the problem?
