2. Next open the Security & Privacy pane by clicking Security & Privacy. (Make sure that the General tab is selected.)
 
3. Click the icon labeled "Click the lock to make changes" in the bottom-left corner.
 
4. Enter your username and password into the prompt that appears and click Unlock. (If you have no password, this can be left blank).
 
5. Under the section labeled "Allow applications downloaded from:", select the option "Anywhere". On the prompt that appears, click "Allow From Anywhere."
 
When opening the StatPlanet interactive mapping application, you will get the message:
