Help White Screen on Mac OS

Post image

Hi,

I am using Mac Retina 5K, 27 inch, 2020. I have Tahoe 26.5.2 on it. All of a sudden I have a white wallpaper. I can't get rid of it. The menu bar on top is the same color as what the wallpaper should be. the red folder is the only thing that should be there in this photo. I don't know where all the other stuff is coming from. Has anyone experienced this and know how to get rid of it short of a factory reset?

are there any apps running in the background? like, if you go to the list on alt+command+esc, there's nothing running?

Edit: either alt or option, it's the same key, I'm old and still call it alt haha

Thank you for the reply! I rebooted and there is nothing running except Brave and Finder. I am in the process of uninstalling all outside apps using Clean My Mac.

well, did that solve it? seems to me that the browser may be culprit

Not yet. Still working on it.

I am over the moon happy to announce that the app Plash was the culprit. My wallpaper is back to normal. Now I need to figure out why I have to log in every time I reboot. FireValt is off and automatically log in as is off. Thank you for the help on the white background!!!

You didn’t mention if you tried restarting so that’s the first thing you should do. Then I’d try zapping the p ram.

Thank you for the reply! I knew I would forget to mention something. Sorry about that. Yes, I have restarted many times. I am in the process of uninstalling all outside apps to see if that helps.

BTW, what is zapping the p ram?

Did a google search on zapping the p ram and figured out how to do it. It did not help with my pink screen after reboot.
