Hi, In macOS Sierra there's no more "Anywhere" option to allow install applications downloaded (Security & Privacy Pref Pane). I tried to install the Apache Flex Installer and run with no luck. I only could get it running after reenabling it with this [*]:
sudo spctl --master-disable But I had to reinstall again after doing this, since running the app was failing silently. To reenable: sudo spctl --master-enable If others have the same issue, it would be good to modify instructions [**] Thanks [*] http://apple.stackexchange.com/questions/243687/allow-applications-downloaded-from-anywhere-in-macos-sierra [**] http://flex.apache.org/installer.html -- Carlos Rovira http://about.me/carlosrovira
