I have upgraded my 2018 mac mini to MacOS Catalina and now have pink boot screen every time the computer starts. The OS and all the applications appear to work ok after startup. I have tried the alt+command+R+P at boot to clear NVRAM which I found on an old forum post which worked on the next restart. But at the next cold boot I was back to the pink boot screen. Has anyone else come across this?
Same issue here - except the pink screen continues beyond the initial login.
Clearing the NVRAM (https://support.apple.com/en-gb/HT204063) worked briefly - the login screen displayed in full colour, however once I entered my password and the desktop displayed, it reverted back to the pinkish/purple hue.
Booting in Safe Mode had no effect.
This is with a brand new Mac mini (unboxed this morning), which worked fine until the Catalina upgrade.
Switching monitors and cables (with another working High Sierra Mac mini) has no effect.
Will be downgrading next and let Catalina age on the shelf for six months...
Use the OSD menu and set resolution to 1920 x 1080. How long is the cable? If it’s longer than 3 feet, that could also be an issue. If changing the resolution and/or shorter cable don’t work, get a new monitor. Your monitor is over 8 years old and running HDMI 1.0 = obsolete. Good luck.
Not really. It means that hidden bugs in your monitor have now come to surface. You have an old dog running obsolete HDMI 1.0, give it away to the local school and get something spanking new.
Trust me, Catalina will be thrilled. She’s really not into older monitors. And picky about the newer ones, especially brash, wide-chested Samsungs with gimmicks galore, not to mention cheap LGs without thunderbolts. It’s no secret, Catalina can barely keep awake with them.
Good luck.
I have this same issue and have been on the phone with Apple support for hours, and in and out of the Apple store multiple times. Bought my Mac mini in Jan 2019. No issues until the day it met Catalina. No one knows how to fix it and Apple will jot exchange my Mac. I spend tons of money with Apple and I can’t believe this lack of service.
Have you tried rebooting to safe mode to see if the same thing happens?
No
Rebooting to safe mode will give a black logo screen, but at the next reboot it is back to pink screen.
Thanks for your non help.
Thanks for the suggestion. Apple did say maybe to hold out to see if there’s a patch firstly before going down the reset route.
You’re welcome! Seriously, shrug it off, you won’t regret it.
Just tried safe mode. It did not work. Same status during boot.
I agree, but right now it is not annoying to that point. I'll wait for a patch. Thanks for trying to help.
You also have the option of returning the mini for full refund and shelfing the money...
I ended up downgrading to Mojave - colours are back, everything works fine.
Great. That settles it, your monitor isn’t compatible with Catalina.
Maybe....could also be an issue with your Samsung, BenQ and Lenovo. Mine (Dell) works just fine. Good luck anyways.
Pink Boot Screen after Catalina upgrade.
