When I was looking for a replacement this popped up:
"APPLE HAS ROLLED OUT an update to the El Capitan operating system, which it said will sort out problems Mac users are having with Microsoft Office 2016 on the latest OS.
Apple promises that the OS X El Capitan 10.11.1 update improves compatibility with Microsoft Office 2016, although the firm does not go as far as to guarantee the problems will totally disappear. Since the launch of El Capitan, Mac users have been suffering from Microsoft Office and Outlook crashes, both with the 2011 and 2016 versions."
So it seems I will be looking for apps. For some reason I should have listened to that little person in my head and not started the download of El Capitian! Ugh
