Part 1. Why the Photos Library Could Not Be Opened on Your MacBook
When the Photos Library could not be opened error appears; understanding the cause is the first step toward fixing it. Below, we will discover some common causes that might be a reason for this problem:
- Corrupted Library: This can occur due to incomplete file transfers or malware attacks. In case the library structure is damaged, your system may fail to open it properly.
- Outdated Version: When the system is running an old version, it may struggle to recognize the Photos Library correctly, leading to the error.
- Incorrect Settings: The Photos app requires a designated system photo library for smooth operation. That’s why it can refuse to open it when the selected library is not set as the system library.
- Storage Issues: Corrupted disk sectors or insufficient storage can also prevent the application from loading. Along with that, a failing hard drive can lead to read/write errors and make files inaccessible.
- Access Restrictions: macOS applies strict file permissions to protect user data. In case the Photos Library does not have the necessary permissions, it can fail to open.
