Your Mac can show the first time you launch the app:

Due to security reason, MacOS as default does not allow user to run app from third-party locations.

How to solve this:

1. Open your Mac’s System Preferences.
2. Click on Security & Privacy, then go to the General tab.
3. On the bottom left, you’ll see a padlock icon. Click on it and enter your admin password.
4. Under Allow apps to be downloaded from, select App Store and identified developers.
5. Close all windows and open the app again.
6. If it's still not working, repeat from step 1. to 3.
7. You’ll see the message [App] was blocked from opening because it is not from an identified developer. Now click on the button Open Anyway
8. You’ll be asked again if you’re sure you’d like to run the app. Click the Open button to run it.
9. That's it!
