unpkg is a utility that simply unpacks all the files in a Mac OS X package (.pkg file) into a folder. Very handy, and GNU GPL free too!
Features:
Super quick, no non-sense unpacking
Easy drag-‘n’-drop interface
Extracts both standard packages and metapackages (.mpkg files)
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 the GNU GPL
On GitHub. Clone and fork away
