Hi, I know that osx "open" command < 10.6 does not support command line args, but >= 10.6 seem to support that (so dbl click with passed args to app should work). Now the question: how to add into bundle that my app want to start with params (Info.plist inside myapp.app/Contents) ? Or I should make script inside MacOSX which then call my app .... zeljko
