Like Windows 8, OS X has a specific setting that will completely block a program from being installed if it is not from a "verified developer". If you receive a message saying "(software) can't be opened because it is from an unidentified developer", follow this procedure:
- Make sure the program being installed is from a trusted source and that it is the program that is intended to be downloaded.
- Navigate to System Preferences by either searching for it in spotlight or clicking on the apple icon in the upper left hand corner of your Mac and selecting System Preferences.
- Once in System Preferences, click on Privacy & Security.
- On the General tab you will see a section toward the bottom called Allow applications downloaded from:
- Switch that option to Anywhere in order to be able to install unidentified applications.
- If the selections are grayed out, you to click on the golden lock in the lower left hand corner and enter your computer password.
