Software developers sometimes use a PKG or package file to store the various files needed to install their application, and you might want to extract files that are stored inside of the PKG file. Typically a person double-clicks on a PKG file to install software on the Mac, but if you want to see exactly what is inside the PKG before clicking on it, use a third-party PKG extraction program to extract the files.

Pacifist

Launch your Web browser and navigate to the CharlesSoft website (charlessoft.com). Download the Pacifist application.

Step 2

Double-click the Pacifist DMG disc image file to mount it on your Mac's desktop. Drag the Pacifist application onto the "Applications" folder in the Dock of your Mac.

Step 3

Click "Applications" in the Dock, and then click "Pacifist" to launch the application. Click "Open Package." A dialog box appears.

Click the folder on your Mac containing the PKG file from which you want to extract files. Click the PKG file to select it, and then click "Open" to extract the files.
