Theme Chooser is black
On my MacBook Pro, when I click new file/folder for Keynote, I get a black and empty theme chooser. There are no standard themes like before. This only happens on my MacBook Pro. My icloud keynote for my office iMac does not have this problem. Do I need to delete and re-install the Keynote app?
Thanks in advance.
