Update to Big Sur and lost older flower wallpapers

Hi there maddalena256,

We see you have a question about the wallpaper options in macOS Big Sur, and you're not seeing the flower photos you used previously. We're glad to look into this.

You'll find any available built-in wallpapers under System Preferences > Desktop & Screen Saver, and then in the Apple > Desktop Pictures folder. These options do vary with different macOS versions, but if you don't see one that you're looking for, keep in mind you can use most images you find online as custom wallpaper: Customize the desktop picture on your Mac

Regarding changes in wallpaper over different macOS versions, you can always send your feedback directly to Apple here: Product Feedback

Kind regards.

Thanks for this!

I had this problem also and decided to find the photos and make my own screen saver. go to this site https://ffwallpaper.com/apple-mac-os.html and individually download each of the flower photos or whatever ones you liked from Catalina. Create a new folder then place all the photos in the new folder. name the folder Catalina Flowers then open up System Preferences on your computer then Desktop & Screen Saver. Go to Ken Burns then click where it says Source and scroll down to choose folder. find your folder then push choose.
