Keynote "The document could not be autosaved."
Mojave 10.14.6
I have a large keynote file. All of a sudden it is giving me an error that says.
I cannot duplicate the document.
I tried creating a new document and pasting the contents into that. I got the same error with the new file.
When I quit, I am forced to "Discard" all changes.
I have tried duplicating the file in the Finder as well.
I Tried some other tips like:
File>Recent>Clear Menu
I changed the File permissions for ALL to "Read & Edit"
No luck.
This is a big presentation and I need to move forward with it.
Please help!!
