Screensaver Issues With Big Sur
I have a late 2015 iMAC. Recently installed Big Sur. I have always used Photos as my screen saver. After updating to Big Sur, I was only seeing the same 10 or so photos over and over. Now after going into Systems Preferences to find the problem and choosing "Classic," there is a floating message in the computer picture that says: "You cannot use the iLifeSlideshows screen saver with this version of MacOS. Please contact the vendor to get a newer version of the screen saver." How would I do this? Is the vendor Apple? Thanks for any help.
iMac 21.5″, macOS 11.1
