Sentinel Dongle Driver – macOS 10.13.x / 10.14.x App Security permission

Serendipity Blackmagic / Megarip / Veripress users with Sentinel dongles may encounter the following messages when starting the Blackmagic / Megarip / Veripress Server immediately after software installation or after a macOS 10.13.x or 10.14.x Security Update:

  • After a fresh install or a macOS Security Update, this message may pop-up when starting the Server.1.DongleMacOSSecurity-4-16-error
  • This message pop-up may appear after a macOS 10.13.x or 10.14.x Security Update.2.DongleMacOSSecurity-Ext-Blocked

In both instances error and/or message is generated due to macOS revoking the Sentinel System [dongle] Driver third-party app load permissions.

Note – it is assumed that Sentinel Dongle users have previously installed the required Sentinel System Driver 7.5.4 package

To fix the issue:

  • click the Open Security Preferences button in the ‘System Extension Blocked’ message above.
  • or, open macOS > System Preferences > Security and Privacy > General tab, a ‘System software from developer “SFNT Germany GmbH” was blocked from loading.’ notification will be displayed in the Allow app downloaded from: panel.

  • Click the lock to make changes to the Security & Privacy settings4.DongleMacOSSecurity-System-Security-unlock-allow
  • Click the Allow button to give the Sentinel Dongle driver loading permission.
  • Then click the Restart button in the ‘Enabling this system software requires a restart’ pop-up dialog.5.DongleMacOSSecurity-System-Security-restart

MacOS will then restart.

When the machine is up and running again, the Sentinel Dongle will be recognised and the Blackmagic / Megarip / Veripress Server should start up normally.
