SpeechControl can't be opened on macOS.

When trying to open SpeechControl for Mac, following error occurs:

"SpeechControl" can't be opened because Apple cannot check it for malicious software.

To resolve this issue you have to make some adjustments in the Security settings of the Mac:

1. Open System Preferences and select Security & Privacy.
2. Click on Open Anyway next to "SpeechControl" was blocked from use because it is not from an identified developer. 
   
3. Click on Open.
