Important note: IRIScan Express 4 & IRIScan Executive 4 are no longer supported on macOS by IRIS. At the moment, it's still possible to use these scanners on macOS 10.15 and above following the procedure below.

The message "Initialization failed" is linked to Apple which has reinforced its development protocols. You must manually authorize the installation of all scanner components.

To do this, follow this procedure:

• Restart the Mac (Note that you have 30 minutes to complete the following steps, otherwise some features will not be displayed)
• Unplug the scanner
• Go to "System Preferences"> "Security and Confidentiality"> "General" tab
• Click on "Authorize" in the window that appears.
• Restart your Mac as requested
• Test a scan

It may be required to unplug/plug the scanner again after the restart.

If the solution above didn't work as intended, feel free to open a ticket. One of our agent will gladly help you.
