Contacts missing on iMac after upgrade to High Sierra 10.13.2
My contacts are on my phone and ipad, and the names show up on my Mac, but when I click on a card, there's nothing there. I've installed the security update, restored contacts on icloud.com, switched on and off and on and off and on the setting for iCloud contacts in the contacts app, but no go. What now?
iMac (21.5-inch, Late 2012), High Sierra, 10.13.2
