I’ve recently started attending IRC meetings. Since I run a Mac, I had to do some digging to understand the best possible IRC clients out there. Fairly quickly, I discovered LimeChat. It’s a very versatile IRC client, the UI is pretty clean, and it doesn’t appear to suck a ton of resources. Overall, I’m quite happy with it, and would recommend it for anyone looking for a slick IRC client on the Mac. Check it out either at the website above, or in the Mac App Store.
