It looks as if Apple's security model for macOS meant that a friend lost some work she had done using LibreOffice Writer.It appears that one needs to go to macOS System Preferences > Security and Privacy > Privacy, and give full disk access to LibreOffice, before macOS will save the file correctly.This may be well known, but clearly it is not known to everyone, and hopefully this might help someone out there!#macOS #LibreOffice
