With the release of macOS 15 Sequoia, Apple has implemented a new security measure that affects how certain applications, including CloverDX Designer, are opened. This article will guide you through the updated process to ensure you can seamlessly access CloverDX Designer on your macOS 15 device. Follow the same steps when installing trial CloverDX Server environment locally. 

1. Run CloverDX Designer to get the "blocked" dialog.

2. Open System Preferences, navigate to Security & Privacy.

3. Locate the blocked app in the Security section. You will see a message stating that "CloverDX Designer <version>" was blocked to protect your Mac. To enable the app, click the Open Anyway button.

4.  Click Open Anyway again in the confirmation dialog.

5. Enter administrator's credentials. 

6. You should now be able to launch CloverDX Designer without issues.
