Just upgraded to macOS 10.12.16. For some reason my iCloud contacts are empty. Contacts.app does not show anything.

I tried signing out of iCloud, deleting AddressBook caches and files in ~/Library/Application Support and then signing in again. Still, no Contact gets synced.

I can see all of my contacts via www.icloud.com and on my iPhone.

Can anyone help me?

I've been having this issue for a couple of months and fixed it by doing the following:

  • Quit Contacts.app
  • Delete all content of ~/Library/Application Support/AddressBook
  • Remove Contact sync from iCloud preferences in System Settings
  • Wait couple of minutes, and re-enable Contacts sync
  • Open Contacts.app and wait. Everything appears, and now Contacts syncs properly both ways.
