That said, implement these go-to procedures to fix the error. Prior to initiating the repairing process, it is recommended to backup all your files so that in case something unexpected happens at least you can restore your original files.

If you don’t have the permission to open your JPEG/JPG files, the following might be the reasons:

  • The problem could be due to a third-party installer. To elaborate, you may have multiple accounts on a Mac device and it is possible that you might have installed a third-party application while logged in to another user account; therefore, install applications with your normal user account
  • You might not have the root ownership of the files and folders
  • Files and folders might have been affected due to power interruption
  • Files have been infected by viruses or the storage media has bad sectors

Methods to fix the error:

i. Delete some files in the library

If you’re unable to open JPEG/JPG files, quit the photo viewing application and backup all your photos. Then go to the Finder menu bar, hold down the Option key, and select Go < Library. Under the Library folder, delete the following items:

  • Containers/com.apple.Preview
  • Saved Application State/com.apple.Preview.saved state
  • Preferences/com.apple.Preview.LSSharedFileList.plist
  • Preferences/com.apple.Preview.SandboxedPersistentURLs.LSSharedFileList.plist
  • Caches/com.apple.Preview

After deleting the items, try opening JPEG/JPG files, if everything works fine, then well and good else proceed with the next step.

ii. Run Disk Utility

The problem could be with your Mac hard drive and to fix the error, you need to run Disk Utility in order to regain access to your photos.

There might be a probability that your drive is corrupt or damaged and that is causing the issue. Disk Utility is the preferred way to eliminate disk-related issues as it scans the disk’s structure for errors and automatically fixes it.

To fix the error, follow these steps:

i. Restart your Mac and hold down ‘Command + R’ until the Apple logo appears on the screen. macOS Utilities is displayed, select Disk Utility
