How to fix Mac Notes not syncing with iCloud or between devices

If your notes are not appearing across your Mac, iPhone, or iPad, or if changes made on one device are not reflected on another, the cause is almost always related to iCloud sync settings, account configuration, or local caching. This guide walks you through the most effective fixes, starting with the quickest checks and moving through to more thorough troubleshooting.

Quick Fix Steps

Start with these rapid checks. They resolve the majority of Notes sync problems within minutes.

1. Confirm your Mac is connected to the internet. Open Safari and load any website.
2. Check the Apple System Status page to ensure iCloud Notes is not experiencing an outage.
3. Restart your Mac. Go to Apple menu > Restart.
4. On your iPhone or iPad, open Settings > Notes and ensure “On My iPhone” Account is not the default. Set the default account to iCloud.
5. Force quit and reopen the Notes app on your Mac. Press Command + Q while Notes is active, then reopen it from the Dock or Applications folder.

Detailed Instructions

1. Verify iCloud Notes is enabled on your Mac

Notes sync only works if the service is switched on for your iCloud account.

1. Open System Settings (or System Preferences on macOS Monterey or earlier).
2. Click your Apple ID at the top of the sidebar.
3. Select iCloud.
4. Under Apps Using iCloud, click Show All (or Show More Apps on older macOS).
5. Locate Notes and ensure the toggle is on.
6. If it is already on, toggle it off, wait 10 seconds, then toggle it on again. This forces a re-sync request.

2. Check the Notes default account

Notes created under a local “On My Mac” account will never sync to iCloud. You may have inadvertently saved notes to the wrong location.

1. Open the Notes app on your Mac.
2. In the sidebar, look for the account headings. You should see iCloud and possibly On My Mac.
3. If your missing notes are under On My Mac, they are stored locally only. To move them to iCloud:
   1. Select the note or folder under On My Mac.
   2. Drag it to the iCloud section in the sidebar.
   3. Wait a few minutes for the note to upload.
4. To prevent future local-only notes, open Notes > Settings (or Preferences) from the menu bar, and set Default account to iCloud.

3. Sign out of iCloud and sign back in

This refreshes your iCloud authentication token and often clears stuck sync queues.

1. Open System Settings > Apple ID.
2. Click Sign Out.
3. Choose which data to keep a copy of on this Mac. For Notes, you can keep a copy, but the synced version will be restored after signing in.
4. Restart your Mac.
5. Go back to System Settings and sign in with your Apple ID.
6. Re-enable Notes under iCloud settings if prompted.
7. Open Notes and wait up to 10 minutes for your notes to repopulate.

4. Check date and time settings

Incorrect system time can break iCloud authentication and sync.

1. Open System Settings > General > Date & Time.
2. Ensure Set time and date automatically is enabled.
3. Confirm the time zone is correct for your location in Australia (e.g., Brisbane, Sydney, Perth).

5. Update macOS

Older macOS versions may contain sync bugs that have been fixed in later updates.

1. Open System Settings > General > Software Update.
2. If an update is available, click Update Now or Upgrade Now.
3. Allow the update to complete, then check Notes sync again.

Troubleshooting Persistent Issues

Rebuild the Notes index

If notes appear on iCloud.com but not on your Mac, the local index may be corrupted. Rebuilding it forces Notes to re-download everything from iCloud.

1. Quit the Notes app (Command + Q).
2. Open Finder.
3. Press Command + Shift + G to open the Go to Folder dialog.
4. Enter the following path and press Return: ~/Library/Group Containers/group.com.apple.notes/
5. Locate the file named NoteStore.sqlite (and any related files such as NoteStore.sqlite-shm and NoteStore.sqlite-wal).
6. Move these files to your Desktop as a backup. Do not delete them yet.
7. Restart your Mac.
8. Open Notes. The app will create a fresh database and re-sync from iCloud. This may take several minutes.
9. Once your notes have reappeared, you can delete the backup files from your Desktop.

Check for conflicting notes or folders

Rarely, a note edited simultaneously on two devices can create a conflict that stalls sync.

• Look for any notes with unusual names or duplicate titles in the Notes sidebar.
• If you find a note that appears stuck or duplicated, copy its content to a new note, then delete the original.
• Check for folders with the same name under different accounts (e.g., “Work” under both iCloud and On My Mac). Rename one of them to avoid confusion.

Check iCloud storage

If your iCloud storage is full, Notes may fail to sync new content.

1. Open System Settings > Apple ID > iCloud.
2. Check the storage bar at the top. If it is full or nearly full, click Manage.
3. Free up space by removing old backups, large files in iCloud Drive, or unnecessary photos.
4. Alternatively, upgrade your iCloud+ storage plan.

Disable VPN or security software temporarily

Some VPNs, firewalls, or third-party security tools can interfere with iCloud traffic.

1. Temporarily disconnect your VPN if you use one.
2. If you have third-party firewall or antivirus software, disable it briefly.
3. Check if Notes sync resumes. If it does, add iCloud and Notes to the software’s allowlist or contact the software vendor for configuration guidance.

Verify Sync Between Devices

After completing the steps above, confirm everything is working correctly.

1. On your Mac, create a new note in the iCloud section of Notes. Type a test word.
2. Wait 2–3 minutes.
3. Check the same note on your iPhone or iPad in the Notes app under the iCloud account.
4. If the note appears, sync is working. If not, repeat the steps above or contact Apple Support for further assistance.
