Every once in a while, Mac OS X (and OS 8-9) jaggies up a Newton OS .pkg file, rendering the package un-uploadable for apps like NCX. Those little creator codes that have caused a ruckus post-Snow Leopard are partly to blame.
That’s where Packager, a Mac OS X app, can come in handy. Packager takes the .pkg file and returns it to its natural, Newton-ready state.
Here’s an example. I grabbed an astronomy app called Moon Phase and downloaded the package file (above right). As you can see, it doesn’t look any different from a Keyspan driver installation package (above left).
Sometimes, Mac OS X 10.5 doesn’t know what to do with a Newton package file when it’s downloaded (above). This is where you take the file, drop it on Packager’s app icon in your Applications folder, and let it do its magic.
Here’s that Moon Phase package file, post-Packager, but now it’s recognized by NCX and ready to be installed.
For WIndows users, try the command-line-operated, dirty-sounding Pkg Stripper by Roger Milne.
