Mac OS X support zip & unzip files natively, but you can’t find how to configure it in System Preferences.
Archives Pane exists but it is not installed by default, so you must install it first:
- Go to (Shift-Command-G):
- Double-click on Archives.prefPane
- Insert your admin password
- From now on you have Archives pane in System Preferences
NOTE: it works on Mac OS X Lion, Snow Leopard and Leopard.
