Gatekeeper by default will only open apps purchased and downloaded from
the Mac App Store or programs from developers that were furnished with
Developer IDs from Apple.
The EnGenius Zone Controller (EZC) does not have this digital signature.
As such, Gatekeeper will need to be disabled and set to allow installation
of software downloaded from “Anywhere”.
Click on the Apple icon and select System Preferences.
Go to Security & Privacy and click on the General tab.
Select “Anywhere” option under the “Allow
applications downloaded from”.
Note: Usually, you will only need to disable
Gatekeeper to install and initially run the EZC.
