unpkg is an easy to use utility that will allow you to simply unpack all the files in a Mac OS X package (.pkg file) into a folder. Very handy, and GNU GPL free too!

Usage: Just drag the package onto unpkg's icon and it will extract the contents into the same directory, with the same name.

NOTE: Unpkg does not touch you system at all except for the folder where the unpacking takes places. Because it does not move files around in your system (on purpose), you should not use unpkg to install, say, incremental OS X updates. But if you just need to get a kext from that package, for example, then unpkg is exactly what you need.

Here are some key features of "unpkg":

· super quick, no non-sense unpacking
· easy drag-'n'-drop interface
· does not require any passwords (unpack all those archives that want Administrator privileges!)
· unpacks both old-style (10.4 and before) and new-style (10.5 and later) packages, even on 10.4
· automatic unpacking of files to a folder named after the package in the same directory if possible, or the Desktop
· good package detection (unpkg will not try to unpack something that's not a package, and easily handles malformed packages)
· licensed under then GNU GPL
