Peek-a-Boo ST is a utility to monitor and manage processes, has been described by one long-time user as the utility I didnt realize I needed, until Id used it.

Peek-a-Boo focuses on two things: clarity and flexibility. From the moment you first launch Peek-a-Boo, it will be clear what is happening with processes on your Mac.

Use Peek-a-Boo to twirl into process-comprehension nirvana.

Peek-a-Boo is the only utility of its kind to show process information for all types of processes: Classic applications, Darwin processes, and OS X native applications.
