Troubleshooting iCloud Photos Sync Issues on Mac
If your iCloud Photos aren’t syncing correctly on your Mac, you’re not alone. Unlike iPads which typically have a single Photos library, Macs allow for multiple libraries, and only one can connect to iCloud at a time. This can often be the root cause of syncing problems. This guide will walk you through troubleshooting steps to get your photos syncing seamlessly.
Understanding Photos Libraries and iCloud on Mac
The core issue frequently enough stems from using the wrong Photos library. Your Mac can have several, but only the designated “System Library” actively connects to iCloud for syncing. If you’re viewing a different library, you won’t see the latest iCloud updates.
1. Verify External Drive Formatting
If your Photos Library is stored on an external drive, correct formatting is crucial. Photos requires the drive to be formatted as either APFS (Apple File System) or Mac OS Extended (Journaled). Incorrect formatting can lead to library corruption and prevent Photos from accessing it.

2. Identify Your System Library
Here’s how to determine which Photos Library is currently set as your System Library:
* Open the Library Chooser: Close the Photos app. Then, while holding down the Option (Alt) key, click the Photos icon to launch the Library Chooser.
* Review Libraries: This window displays all available Photos Libraries, their locations, and indicates which one is the System Library.
* Set the System Library: If the correct library isn’t designated as the System Library, you can change it in Photos’ settings (see section 4).
3. Check iCloud Settings within Photos
Once you’ve identified the correct System Library, verify your iCloud settings within Photos:
* Open Photos Preferences: In the Photos app, go to Photos > Settings (or Photos > Preferences on older macOS versions).
* Navigate to iCloud: Click the iCloud tab.
* Ensure Sync is enabled: Confirm that “iCloud Photos” is checked. You’ll also see options for downloading Originals or Optimized versions. Choose the option that best suits your storage needs.
4. Changing the System library
If you need to switch which library connects to iCloud:
* Open Photos preferences: Photos > Settings (or Photos > Preferences).
* General Tab: Select the General tab.
* “Use this library as the System Library”: Choose the desired library from the dropdown menu. Photos will prompt you to restart the app.
5. creating a New iCloud-Connected Library
A possibly simpler solution is to create a new, empty Photos Library and connect it to iCloud:
- Create a New library: Hold down the Option (Alt) key while launching Photos. Choose “Create New Library” from the Library Chooser.
- Set as System library: Follow the steps in section 4 to designate the new library as the System Library.
- Enable iCloud Photos: Ensure iCloud Photos is enabled in the iCloud settings (section 3).
- Wait for Sync: Allow time for iCloud to populate the new library with your photos and videos. This process can take a significant amount of time depending on the size of your iCloud Photo Library.
Key Takeaways
* Multiple Libraries: Macs support multiple Photos Libraries, but only one can connect to iCloud.
* Formatting Matters: External drives must be formatted as APFS or mac OS Extended (Journaled).
* System Library Designation: Ensure the correct library is set as the System Library in Photos preferences.
* iCloud Enablement: Verify iCloud Photos is enabled in Photos settings.
