Unpack .pkg files.

Overview

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:
  • Universal Binary, 10.4.11 and above
  • 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!

This is a very handy application. Works as advertised in 10.6.8. Just say "No" to blindly installing packages.

Really great app, saves lots of time in the course of an average workweek. It’s even better when you can read the contents of a .pkg using Suspicious Package before unpacking it with unpkg (http://www.macupdate.com/app/mac/26833/suspicious-package). Thanks to the developer for making it free!

Great app. I nearly allways use it to or before installing pkg's. I don't know about .mpkg, but in earlier versions it worked to rename the file to .pkg and then use unpkg.

Works fine for .pkg's but it doesn't work with .mpkg Might prove handy down the road anyways. Thanks

Dropped 3 different packages on this. For 2 of them it kicked out empty folders. I doubt a 1.2 MB file contained nothing.

If you could direct me to the packages, I'd love to look into why they're not working.

I've never seen this much discussion about an icon before. Interesting as it is, an icon is an icon, it doesn't matter.

Works as advertised! But it would be nice if it could extract individual files from the package, too.

The word 'platypus' itself is not in any way copyrighted or owned by the Olympic Committee, but that particular image of an animated platypus is in-fact a mascot from the Sydney 2000 games. Do a bit of research and you'll see for yourself.

One thing that everyone has overlooked is that this new icon is far superior to the old one because it actually provides some affordance to what the software does. While I'm sure the owner of that particular platypus image wouldn't object to a small freeware app using it as an icon, it probably shouldn't have been considered in the first place. Anyway, this is great and useful software.

Am I the only person who thought of using Hexley (the Darwin mascot) instead? The current icon isn't quite as effective, either, since it doesn't really describe what the application does. Perhaps the package icon with arrows coming out of it?

Come on people, IT'S AN ICON! Whether it "provides affordance" or not doesn't change what the app does, does it? Heck, download some new icons and use them if it bothers you so much! Great little app. The fact it can't handle multiple pkg files doesn't hurt, because there's usually only one in a distribution anyway. Neat.

The Developer might want to change the icon, or he might end up in a law suit. (The animal, being a platypus, was a mascot of the Sydney 2000 Olympic Games.)

Thank you. I've changed the icon to something new and original in this version (even if MacUpdate doesn't update it).

Sydney 2000 Olympic Mascot! Don't be ridiculous! The platypus (or it's symbol) does not belong to the Olympic organisation or anyone else. The icon is from the application "Platypus" for creating programs from scripts with a simple interface. http://www.macupdate.com/info.php/id/12046

I am the author of the "Don't be ridiculous!" comment above. Shoot, I see what you mean. The "Platypus" app icon is an exact replica of the mascot. Shame on you "Platypus" developer!
