Issue Description:
When the Printer Enrollment Tool (PET) is initially opened on devices running macOS Catalina, a security warning will be shown indicating that Apple cannot verify the PET application.
Solution:
This error message appears because the PET application is not notarized. To resolve this issue, follow either of the two solutions below:
Solution 1
(Recommended)
Download a new version of the PET application for macOS from the Cloud Fleet Management portal.
Solution 2
The user must manually override the macOS warning to allow the PET application to run.
Go to “System Preferences”.
Select “Security & Privacy”
Click “Open Anyway”.
The warning dialog will be shown again with an “open” button enabled.
Click “Open” and the PET application will launch.
The PET is now saved as a security settings exception, and it can be opened in the future by double-clicking it, just as any authorized app.
Additional Information:
Apple changed the notarization process. The current version of the PET is notarized.
