Well.. I'm fairly new to Macs. I used a PC my whole life, and switched over about 2-3 months ago when I purchased my MacBook Pro. On my PC, I download winrar to unzip files. But I noticed that winrar is a windows program, and I don't know which program I would use for my Mac. I was under the impression that with Macs, when you download a file they automatically unzip themselves (silly me :_P haha). So if anybody can help me out, I would appreciate it. I hope I'm not too much of a pain in the butt.
