iLife Slideshows screen saver not working after update to macOS High Sierra 13.13.3 My screen saver - that shuffles between a list of files in a folder - have stopped working after I updated to 13.13.3. When the screen saver starts it shows a black screen with the following message:

"You cannot use the iLife Slideshows screen saver with this version of macOS. Please contact the vendor to get a newer version of the screen saver."



Also my screen saver preference pane have stopped working - it simple does not switch to that screen when I click the "Desktop - Screen saver" button.

I have tried setting the screen saver using the terminal and the defaults command to update the plist file.
I ended up reinstalling my OS, so it's a solution, a bit drastic perhaps, but very effective.
