After upgrading to macOS Big Sur (11.0.1), the notification of new messages only shows contact number instead of contact names. I can see contact name, profile pics in my Messages.app and Contacts.app, just not in the Notification Center.

I have enabled messages in iCloud on both macOS and iOS.

Any suggestions?

    Did you manage to solve this? I am having exactly the same issue. Nov 27 '20 at 22:08
  • I am also experiencing this. I first noticed it around 11.2.x but it continues to this day—and I am running 11.4 now. Rebooting does not help. Is this some type of corruption in the Byzantine chat.db SQLite database?

I managed to fix this by going to System Preferences > Language & Region. I changed the default language from English (UK) to English (Canada) and quit System Preferences. I then changed the default back to English (UK) and then quit System Preferences again. I then restarted macOS.

I have absolutely no idea why that works. From the number of similar posts on the internet proposing different solutions, I suspect there are multiple possible issues leading to the same problem. However, this it worked for me on macOS Big Sur 11.0.1. Unfortunately I can't find the link describing this solution to give credit but if anyone does find it do link in.

Hope this helps you.

  • Confirmed. It did not fix any of the old notifications, but noticed all my new notifications are correctly showing contact name. Aug 24 '21 at 20:04

I did a bit of digging and uncovered a fairly unobtrusive workaround for this. YMMV, but it worked for me. Tested on macOS 11.4.

By restarting a few system agents, the bug appears to go into remission. This leads me to believe that the root cause is some sort of timing issue or race condition that happens during boot.

Until a proper fix exists, I welcome anyone to try this script (also at luckman212/imessage-number-fix)

#!/usr/bin/env bash

declare -a xpcArr=(
  gui/$UID/com.apple.AddressBook.abd
  gui/$UID/com.apple.AddressBook.AssistantService
  gui/$UID/com.apple.AddressBook.ContactsAccountsService
  gui/$UID/com.apple.AddressBook.SourceSync
  gui/$UID/com.apple.assistant_service
  gui/$UID/com.apple.assistantd
  gui/$UID/com.apple.CallHistorySyncHelper
  gui/$UID/com.apple.ContactsAgent
  gui/$UID/com.apple.iCloudNotificationAgent
  gui/$UID/com.apple.imagent
  gui/$UID/com.apple.imautomatichistorydeletionagent
  gui/$UID/com.apple.notificationcenterui.agent
  gui/$UID/com.apple.telephonyutilities.callservicesd
  gui/$UID/com.apple.usernoted
  gui/$UID/com.apple.UserNotificationCenterAgent
  user/$UID/com.apple.imdpersistence.IMDPersistenceAgent
)

for d in "${xpcArr[@]}"; do
  echo -n "restarting $d"
  read -r PID < <(launchctl kickstart -kp "$d")
  if [ -n "$PID" ]; then
    echo " ✔ [$PID]"
  else
    echo " ✘"
  fi
done

    @luckman212 this is the kind of answer I hope and dream for when on apple SE. Straight to the point, fixes issue, provides reusable script for when it happens, points to repo for updates. Brilliant. Folks this is the kind of engineer you want to hire. Jul 9 '21 at 16:33
