7zip download version for Mac?

I'm not sure where exactly to post this, so forgive me if it's in the wrong forum. Anyway, I'm just wondering if there is a version of 7zip that I can download for Mac? I've already googled it, but it seems like there's more than one version. I don't know what the difference between Ez7zip or p7zip is, or if there even is a difference. I've also come across some links that don't work, and some that the download is only for Windows. So if someone can post a link, or give me some advice on the matter, I would greatly appreciate it. Thanks.
