4 Methods to Open and Repair Photos Library

If creating a new Photos library hasn't resolved your issues and you are still viewing messages such as the following when you try to open your photos, we might have to go a bit deeper to address the issue. Read on to know about four effective methods to open and repair your photos library.

Method 1: Use the Photo Library Repair Tool on Mac

Apple provides a repair tool to address a corrupt Photos library. The repair tool examines the library's database and repairs any conflicts it senses. Depending on the magnitude and size of your library, the whole process could take a bit of time. When the process is done, Photos opens the library again, with your files intact.

Here are the steps to use the Photo Library Repair tool for your issues,

1. Locate the Photos Library (in your Users folder, within the Pictures folder)

2. CNTRL-click Photo Library and select "Show Package Contents".
3. Open the folder called "Masters." This folder contains your original image files, organized by year.

4. Start copying the contents to a new location, one folder at a time. Make sure you are truly copying the folders, not simply moving the originals by holding the Option key when dragging the folder to the new location.
5. If the copy fails, it implies it has hit a corrupt image file in the folder — which is probably the problem, or part of it (there could be more than one corrupt file). In this case, copy failure might actually be a good thing, because we're now hoping to locate a corrupt file. In the case of copy failure, start again by copying the folder where you came across the issue, but his time, copy a few files at a time until you find the corrupt one(s). You'll need to manually create a folder in the new location with the exact same name to copy those files into. Skip any corrupt files — however, remove them from the original folders— and keep copying.li>
6. Continue this process until you've copied all the folders from Masters. The damaged image files are likely lost but maybe recoverable with third-party tools.
7. Once you have all the files copied, you know they are good.
8. Launch Photos and run the repair tool again.

9. The repair app will repair your library eliminating inconsistencies and discrepancies.

Method 2: Restore Lost Photos from Time Machine

Time Machine lets you peer within the Photos Library to salvage specific images that go missing, however the best advisable route of action is to retrieve the entire archived library. This naturally would require enough storage space, either on the startup volume, the Time Machine volume, or another external drive. It is advisable to use an external drive in this case.

Note: If you are normally using iCloud Photos and you restore the System Photo Library from a Time Machine backup, any photos you've deleted since the last Time Machine backup are reestablished to your Mac and uploaded to iCloud again.
