I think the main reason you couldn't find a mac version to download is that there is none.

The closest I saw was a .tr.gz file (i.e. a gzipped Tape ARchive) of Unix source code, but A) I don't know of their definition of "Unix" includes OS X / MacOS; and B) judging from your comments here, you don't seem like the type who would want to install software by downloading, decompressing, and compiling source code.

I'm thinking the people who told you to use PuTTY were assuming that you are a Windows user.
