High Sierra contacts not working

I had the same problem and tried everything. Including everything on this thread. The only thing that worked was creating a new profile and deleting the old. HTH.

Try restarting and see if that fixes the problem.

If that fails, boot into the Recovery Drive and run First Aid in Disk Utility.

Make a note if your drive is formatted as HFS+ Mac OS Extended Journaled or APFS in Disk Utility.

If your drive is OK, select to reinstall macOS.

This will not erase your personal data. However, it's always advised that you backup first in case of unexpected problems.

Boot into the Recovery Drive by holding down Command R when restarting.

See this link for help moving to a new User. Basics are the same. Be very careful with what you bring over from your User's Library. Best to sync as much as you can via iCloud and let it download into new User.

Move your data to a new User or a new Mavericks partition

Hi Diane,

I've tested with a new user and syncing Contacts via iCloud (and nothing else), and the issue is absent there. So, it would appear to be an issue with my current user.

I compared ~/Library/Application Support/AddressBook between the two accounts and found they differed.

So, once again, I deleted ~/Library/Application Support/AddressBook. On recreation (after logging out then in), the differences remain. There are some file size diffs, but significantly the /Images directory is not recreated -- it contains a single file in the test account -- and the /Metadata directory contains only the .info file; whereas the test account contains 3 additional files (named as UUIDs).

Where the files sizes differ (between the two accounts), they are smaller on the recreated account.

These data seem to indicate a failure during creation of the address book on the non-test account. The address book appears to be incomplete; which is likely to be the cause of the other issues.

Of course, an error message in the logs would be nice here, but as with suggestd (which only reports abnormal code: 1) there is nothing usefully reported, which is a shame.

Just a thought... I use Little Snitch to monitor internet traffic on both my iMac and Macbook. It is possible that this was a factor in Contacts not working on my iMac under 10.13.2 and that the installation of 10.13.3 reset Little Snitch. My thinking is that the problem seems to be related to Contacts connecting to iCloud.

Maybe temporarily turn off the macOS firewall, if you have it turned on, and see if that fixes the problem?

Just letting everyone know that it seems that the bug has been quashed, for me. Installed 10.13.4 Public Beta and contacts now opens seamlessly. Good luck to others who have been on this long, long journey to reliability!

Testing in a new User will quickly tell you if the problem is system wide or if it's your User's folder that contains the problem.

CREATE A NEW USER

Go to System Preferences --> Create a New User in Users & Groups.

Switch to the New User by logging out/in or use Fast User Switching.

Log in with your Apple ID. You can only select Contacts for this test.

Only default Apple apps will be in the Dock in the new User. Go to Applications to open other apps you might want to test.

Do you still see the issue?

If yes, then the problem is with your base files or it could be hardware related.

If no, then the problem is in your User's folder.

I am unsure of how this happened to me , MOST LIKELY ICLOUD. But the answer ,(For me) ,was to open contacts and select myself , then in the toolbar select CARD _ MAKE THIS MY DEFAULT CONTACT , somehow SIRI changed it to a blank me. At least thats what the contact stated ("Found by Siri") .

Take back up of data and see this article How to reinstall macOS - Apple Support

The contacts are saved on iCloud server and web mail servers once the fresh installation is completed , enter in system preferences > internet accounts > check the boxes of contacts both in iCloud account and webmail account they will automatically get downloaded in address book .

Another interesting fact. If I logout, and then login as a different user that is setup with my appleid, the errors go away and the contacts.app works perfectly. It must be some problem in my usernames config-files. There is a ******** of stuff in my original accounts ~/Library/Application Support directory compared to the simple test login I set up.

Don't underestimate the bug reports you send in. You rarely hear back but the report is logged and the info you send helps Apple find a fix. Make sure you attach a sysdiagnose report. This contains detailed info on your Mac.

How to attach a sysdiagnose to send Bug Report

The solution dianeoforegon posted from Dave Sag worked for me (thank you as it's been bugging me for ages!). The one thing I'd say is that after I had manually eyeballed all the files with addressbook and deleted those from the stated folders I also did a search of the library which highlighted some I'd missed. You then have to carefully look to see which folder they are in before deleting... then followed the remaining steps and all good.

Go into your System/iCloud preference pane and make sure the Contacts checkbox is checked. If it already is, uncheck it, reboot and then recheck it:

Hello,

I have just reported this bug as a developer at Apple Bug Reporter. You could do the same, but be prepared to submit technical details. Open the Console app, under the category System Reports, you should see a Contacts_DATE_MACHINE.hang report. Right-click on it, select "Show in finder", and attach the file to your report.

Or else you can use the standard customer feedback system. See here for a list of feedback mechanisms : :http://www.idownloadblog.com/2016/04/15/how-to-submit-feedback-and-bug-reports-t o-apple/

I've seen this happen on a new iMac fresh out of the box. Logged in with Apple ID and selected sync. Nothing else installed. Sync failed. User had three other devices. Sync worked perfectly with one device but not on others.

The fact that is only affects some users and some devices is making it very difficult for Apple to track down the cause.

In the mean time, you could try adding a Gmail account and move your contacts to Google and see if that syncs properly.
