visual paradigm can’t be opened because apple cannot check it for malicious software code example
Example: “MySQLWorkbench” can’t be opened because Apple cannot check it for malicious software.
...[MySQL] will appear in System Preferences > Security & Privacy,
under the General tab. Click Open Anyway to confirm your
intent to open or install the app. After this, Workbench app
is now saved as an exception to your security settings, and
you can open it in the future by double-clicking it, just as
you can any authorized app.
