The documentation for launchedApplications warns that the result is not guaranteed to be up to date. As Yen-Ju mentioned, this is mainly because crashed applications don't notify NSWorkspace when they terminate. That being said, when I have experimented with launchedApplications on earlier releases, it has worked as documented. It has given satisfactory results, except when I have killed applications in some kind of rude way. You should therefore feel free to file a bug report about getting all installed applications. It would also be nice if NSWorkspace in some way managed to always know the correct set of running applications, but I guess that would require some kind of probing which would affect performance. And not only when someone asks what is running, but periodically as it's possible to receive notifications when apps launch or terminate. Since NSWorkspace knows the PID for each application, checking whether the process still exists might be good enough.
