ntroducing Mac UnPac, my first Sims 2 Program written in Java! This is designed specifically for Mac users but can also be used by Windows users. Instructions for that are below. Mac UnPac is simple, but has the following features:
See What You're Installing: View the name, size, and custom content type of each package contained within the Sims2Pack before you install it!
Remove Unwanted Packages: Remove any items from the Sims2Pack file before you install it, thus saving time and preventing every random object in the world from entering your downloads folder
