Are you all updated to the latest Mac OS? I've tried everything on my iMac running macOS Sierra 10.2.6 and nothing works. Deleted previous versions of ID and all preferences, reinstalled the latest version of InDesign after restarting my iMac and still nothing worked. Do I have to upgrade to the latest macOS for this to finally work?
