‘You do not have permission to open the application when using a scanner on

Mac

You might get this error when you try to use your scanner from within Image Capture, Preview, or Printers & Scanners preferences.

When attempting to connect to your scanner and begin a scan, you might get a message that you do not have permission to open the application, followed by the name of your scanner driver. The message says to contact your computer or network administrator for assistance, or indicates that your Mac failed to open a connection to the device (-21345). Use these steps to resolve the issue:

1. Quit any apps that are open.
2. From the menu bar in the Finder, choose Go > Go to Folder.
3. Type /Library/Image Capture/Devices, then press Return.
4. In the window that opens, double-click the app named in the error message. It’s the name of your scanner driver. Nothing should happen when you open it.
5. Close the window and open the app you were using to scan. A new scan should proceed normally. If you later choose to scan from a different app and get the same error, repeat these steps.

This issue is expected to be resolved in a future software update.
