Peek-a-Boo is the most intuitive way to explore what’s happening in the universe of processes on your Mac. It is a Mac OS X utility to monitor and manipulate all running processes. You can watch how much CPU time each process uses, adjust processes’ priorities, and monitor process information; the innovative process throb window shows in an instant the activity of all the processes on your system.
There are two varieties of Peek-a-Boo: you can buy Peek-a-Boo for $8.99 from the App Store, or you can use Peek-a-Boo ST, a $19.95 application (with 30-day free trial) that has a few extra features and capabilities.
There are two “flavors” of Peek-a-Boo. One is an in-the-pipeline version of Peek-a-Boo that will be available on Apple’s Mac App Store. The other is downloadable from this web site, and is known as Peek-a-Boo Supplementary Technology or “Peek-a-Boo ST”.
Peek-a-Boo ST includes a component (PeekHelperB) that cannot be distributed by Apple’s Mac App Store. Much of Peek-a-Boo has been re-architected to comply with Mac App Store requirements, but there will still be a few features for which Peek-a-Boo ST is required.
For a little discussion about Peek-a-Boo vs. Peek-a-Boo ST, please see our blog post Peek-a-Boo & the Mac App Store.
As you view these web pages, any differences between Peek-a-Boo and Peek-a-Boo ST will be mentioned with something like “ST only feature”.
There are many ways to peek under the hood of Mac OS X with Peek-a-Boo; you can choose between watching overall system behavior in a variety of windows, or zoom in to scrutinize individual process behavior. (A full description of what’s new in each version of Peek-a-Boo is always on our version history page.)
These views focus on broader overall system behavior, taking all processes into account.
