How to download Minecraft Forge 1.6.4 on my Mac OS X 10.5.8?

I have the forge installer.zip file, but for the life of me I can't get it to open (If I use text edit, I can see the coding, but not sure what to do with that) and things like winrar/unrar and 7zip aren't helping. I've tried everything, and on youtube there doesn't seem to be any help.

.zip files should automatically unzip when you open them on your Mac. Either the file is corrupt, your Mac's "Unarchiver" is broken, or the file itself is broken, which is most likely. Did you download it from a Mac specific section? Did you get it from an official provider? If not, your file is most likely incompatible or broken, try getting a fresh copy.
