Whilst trying to install the VideoScribe software, an error message is displayed advising “VideoScribe" can’t be opened because it is from an unidentified developer (A).


This error message appears when you try to install the software and your security settings only allow applications from the Mac App Store to be installed.

Step 3: Locate the VideoScribe application in your Applications folder and open the application

You need to open your Applications folder and double click on VideoScribe (F).

If you get another message saying the application cannot be opened ‘because it is from an unidentified developer’ (G) follow these further instructions.
