How do I open a .zip file when my Archive Utility app has disappeared and I cannot open a .zip file. Help.
I've read many discussion threads about Archive Utility disappearing but haven't been able to solve my problem. I am running OS X 10.8.3 and do not have an Archive Utility application and cannot open a .zip file. There is a .99 app at the App Store but I don't understand why this is not a free app within Apple OS. Help.
MacBook (13-inch Aluminum Late 2008), OS X Mountain Lion (10.8.3)
