An unexpected error has occurred. Please quit and reopen keynote
Running High Sierra on my elderly macbook pro has seemingly corrupted Keynote; it opens files but when I try to play the slideshow the error message "An unexpected error has occurred. Please quit and reopen keynote"
comes up. I have followed previous recommendations to delete the application and also its folder from the applications support folder and deleted the plist. Then I re-installed iWork 09 from the DVD and then run the iWork 9.3 updater. And still the problem recurs, rendering Keynote useless.
Any ideas anyone, please!
