It seems that a lot of Mac users use Little Snitch and similar products to prevent software from phoning home and use stolen serial registration numbers, etc. For an application, I am thinking about having a separate email/telephone registration process when it's discovered that Little Snitch is present on the user's Mac. I detect that Little Snitch is installed by checking whether the NSURLs returned by [[NSWorkspace sharedWorkspace] URLForApplicationWithBundleIdentifier"at.obdev.LittleSnitchConfiguration"] [[NSWorkspace sharedWorkspace] URLForApplicationWithBundleIdentifier"at.obdev.LittleSnitchNetworkMonitor"] [[NSWorkspace sharedWorkspace] URLForApplicationWithBundleIdentifier"at.obdev.LittleSnitchUIAgent"] are non-NULL or not. Could somebody who has Intego installed on their machine give me the bundle identifier for their outbound firewall product? (I can't remember what they call it exactly) What other popular programs are used by Mac users to prevent applications from phoning home? Thanks!
