Please follow these simple steps to solve it:

Please reset your Mac OS in this path: System Preferences> Security & Privacy > General > Anywhere. And then, open Mockplus again.
But, if you do not find a “Anywhere” option there, please set it as follows: Applications > Utilities > Terminal.app.
Then, enter the command: “sudo spctl --master-disable” and follow the guide to complete the settings. Then, you can freely open and use Mockplus as before.
