I'm launching an application using NSTask and using NSPipe to get it's stdout and stderr. I'd like to hide it (the GUI) on launch, as the app just does some commands and exits. I can't use NSWorkspace since I need stdout/stderr. Does anyone know of a way to achieve this?

is the application being launched an application that *you* have the code for, or is it some other application that you (or the user) bought & installed? – Michael Dautermann May 18 '13 at 20:34

Some other application that the user installed. – Patrick Pijnappel May 18 '13 at 21:55

NSRunningApplication will hand you an object representing the app if you have its process ID: +[NSRunningApplication runningApplicationWithProcessIdentifier:], which you should be able to obtain from -[NSTask processIdentifier].
Then you can send hide to the NSRunningApplication instance.

This does work, but it only works once the app gui is fulled loaded and shown, so it will noticeably be visible for a split second before it is hidden. – Patrick Pijnappel May 18 '13 at 22:18
