Specific error messages

It can't be opened because it comes from an unidentified developer

This error occurs on the Macintosh operating system when trying to open a help program installed from the Tax Agency website.

To install the program, you need to grant execution permission from the security settings. To do this, go to "Security and Privacy" in "System Preferences" in Applications.

Check the "Anywhere" option in the section to allow downloaded applications (by default, the "Mac App Store and identified developers" option will be checked).

After downloading and installing the program, we recommend that you return to the original permission settings to avoid security issues.
