Disabling the dialogs shown when opening an application for the first time on OSX I am making an app on osx 10.9 using python 2.7. But when it is launched first time, warning comes.


  You are opening the application MYAPP for the first time. Are you sure
  you want to open this application?
  
  The application is in a folder named Applications. To see the
  application in the Finder without opening it, click Show Application.


So, how to avoid this warning. Does I need to make some changes in info.plist of app.

I had gone through this Q&amp;A but nothing is mentioned about app side changes.

I don't want user to use any sort of command to run or do changes manually. User can disable by "com.apple.LaunchServices LSQuarantine -bool NO" for all or "xattr -rd com.apple.quarantine Application.app" for particular app.

I had also signed the app with developer ID.

So, how to disable this dialog box from popping.
Simply right-click your application and choose "Open".  That immediately gets around Gatekeeper without disabling the feature (which is highly effective at keeping the mac safe from drive-by infections).
