Sentinel License Development Kit (LDK) is a service used by Caldera to manage software and hardware licences.
When you install CalderaDock version 3.2 or later, Sentinel LDK is installed automatically:
Info
Sentinel LDK requires access to port 8443 or 443. Ensure that your local firewall allows the required connection.
If you experience licence issues, go to CalderaDock > Licences > Sentinel, then click Reinstall. This updates Sentinel LDK and may resolve common licensing issues.
You can also download the current version of Sentinel LDK from the Thales Support Portal. Sentinel LDK supports many popular operating systems, including supported versions of macOS. For the complete compatibility list, see the Sentinel LDK supported platforms documentation.
For additional information, see the official Thales Sentinel LDK documentation.
Check background activity on macOS 13 or later
Sentinel LDK requires its Thales background activity to remain enabled:
- Open System Settings > General > Login Items & Extensions.
- Under App Background Activity in macOS Tahoe, or Allow in the Background in macOS Ventura, Sonoma, and Sequoia, confirm that THALES DIS CPL Deutschland GmbH is enabled.
- Launch your application either directly or by clicking Launch in CalderaDock.
- If the application does not open or the licence is not detected, restart your Mac and try again.
The check is successful when the application opens normally and detects its Sentinel licence or USB key.
If the issue continues, open CalderaDock > Licences and check both the licence status and the Sentinel status in the License Manager section before contacting support.
