Ask HN: What's the best IRC client for a Mac?

I really like XChat Aqua (http://xchataqua.sourceforge.net/). It's not really being maintained anymore, but don't let the low version number scare you. It has never crashed on me once. I like it because I was so used to XChat on Linux, it provides me with a familiar interface.

If you're hardcore, try MacIrssi (http://www.sysctl.co.uk/projects/macirssi/), which is seeing lots of active development.

What is it you do not like about Colloquy? That will probably lead to better answers to your question.

I'm using LimeChat (http://limechat.net/mac/). It's a pretty good client. Supports multiple irc servers, highlighting, ... everything you want :)

I have switched to the beta version of adimu. It has decent IRC support. I have used colloquy and irssi/bitchx in the past

I used to use emacs and XChat, but now I just prefer to use Mibbit.

Not that I've found...

BitchX

irssi
