Today's operating systems frequently look to see where the application you are installing has come from. By default your MacOS is set to only download App from the AppStore which increases our costs to you by 30%. To temporarily open up your MacOS to download from any developer please do the following:
1. Click the Apple Menu and select System Preferences
2. Open up privacy and security
3. Click the lock icon in the bottom left corner of the window.
4. Select "Anywhere" radio button
5. Click the lock icon
By following the reverse procedure, you can reinitiate the same security settings on your MacOS.
