Distributing my Mac app to friends

Hello I have made an app in Xcode for mac (in cocoa). I want to distribute it to my friends via ichat or mail. But when I copy and sent it, 开发者_如何学Goit doesn't run. I have also changed the permission to 777 but still it doesn't run. I think there is some permission problem. I went inside my app say x.app and changed the permission of x under the Mac_OS folder. Any help Regards, Abhi

If you haven't already, I recommend archiving your application directory into either a TAR archive or a ZIP archive, or packaging it into a disk image formatted in HFS+ before transferring it.

Keep in mind that Macintosh files can potentially have a lot of metadata associated with them, and that it will be otherwise lost if an attempt is made to transfer them over a network using HTTP or SMTP as-is.
