iCloud contacts won't sync

I was getting the issue, well a similar one at least.

My problem was that my the iCloud contacts account just didn't show as an option in the contacts app. I disabled contacts in iCloud settings, then re-enabled, but that didn't work. I tried removing my whole iCloud account and then adding it again and that didn't work.

2 restarts later and after removing iCloud and adding back in again, I finally have my contacts back. I had given up on it, but thought I'd check again to see what error I was getting to see if it was the same as yours, but my contact were there, so sorry, I can't give you any more info.

I had the same problem with OS X server contacts through carddav - I had to delete and re-add accounts to have it working. And as soon as I try to enter account in Contacts.app, it will lead the app to crash. I had to set everything up through System Preferences -> Internet Accounts and to restart to have it working, again
