contact card info blank on iMac
after recent os High Serriea updates, my contacts cards info is blank on my iMac but everything is still on iPhone. Nearly all my apps are glitchy and have run every recommended antivirus programs and nothing is suspicious. My Office 365, Google Drive and Dropbox accounts and iCloud storage apps aren't syncing correctly anymore either. So frustrated having to use Windows 10 Laptop next to my iMac just to get simple work tasks done. Microsoft and Apple apps are playing nice anymore.
How do I fix these issues?
