let process = Process() process.standardOutput = FileHandle.nullDevice process.standardError = FileHandle.nullDevice process.launchPath = url.path // path to app process.arguments = [“arg1”, “arg2”, “arg3”] process.launch() and if you need to process.waitUntilExit() Obviously don’t wait on the main thread! I do this in an app where the URL points to a helper located in the bundle. Not sure what extra hoops you’d need to jump through to launch an app outside of the sandbox. Probably needs user approval which can be remembered using a security scoped bookmark. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
