This message can sometimes appear for users of Mac OS X 10.9 or later when the computer’s security settings are blocking all software installation outside the Mac App Store.
To resolve the issue, open System Preferences and go to the General tab in the Security & Privacy panel.
There will be some settings at the bottom advising which kinds of applications your computer is permitted to install. If it’s set to ‘Mac App Store’ only, you can try a lower security setting (temporarily, if preferred) to clear the error. You may also see a message about your HUE application with the option to grant it permission to run without changing any settings.
If the software will only open when you pick the lowest security setting please contact us. It should be classified under ‘identified developers’ since the software has been signed by Apple.
