Applications, such as Sportscode, which are not available for purchase through the Mac App Store, will often prompt this error message during install: Your security preferences allow installation of only apps from the Mac App Store and identified developers. This isn’t cause for concern, it’s just a default Mac setting. Follow these steps to get your system ready for the installation of Sportscode.

Click the padlock icon. You will need to enter your Admin password.
