How do I use IRC on a Mac?

Like me, it sounds like you probably either use specific instant messenger programs like Yahoo Instant Messenger, Google Talk or AOL Instant Messenger, or you use a Mac multi-IM client like Adium or Fire. They're darn nice, particularly the last two, but none of them are compatible with IRC chat rooms.

(Well, Fire is IRC compatible, but I have to say that I find it quite difficult to configure it for an IRC channel and have it work properly. Your experience may vary, of course)

The good news is that just like any other area of Mac computing, there are a couple of really nice Mac IRC (which stands for Internet Relay Chat, by the way) clients, the very best of which is Colloquy. Let me show you how, using this freeware program, you can join an IRC channel too.

More likely than not, you were given an IRC server, a port or channel, and a specific chat room ID. It might look like irc.freenode.net, port 6667, chat room #yourbiz. Once you've downloaded Colloquy, launch it and you'll see a basic connection window. Click on the small blue triangle labeled "details" and here's what you'll see:

You can see here that I've already filled out the critical information to be able to connect to the server in question.

Choose "Connect" and you'll be hooked up to the IRC server in just a few seconds. Once you're connected, just choose File --> Join Chat Room... and type in the name of the specific conference room you've been told about.

Now, you'll be able to chat away. Here's what a typical chat room looks like:

Once you start running Colloquy, however, spend some time exploring the various customizations too. It's very nice.

Hope that helps you out!
