You can mod minecraft in the mac.
Where can i download the mod
Nope. You HAVE to download a minecraft mod to have it.
its a mod P.SL mac or windows, minecraft is the same
GO to ragusumis mods...type in modloader download scroll down until you see it next to his other mods and download it
Just search in google 'Minecraft mod downloader'
If you are talking about just Minecraft with no mods and just the vanilla game you don't need anything but the game. If you need to download a mod just look up tutorials on YouTube on the mod you are installing and specify that the installation is for mac or you'll get a PC one.
You can download it of the official minecraft forums.
Download it of the INTERNET and then put it on minecraft
