The only chat application necessary on a Mac has just hit 1.0. Adium is the duck of all trades as far as instant messaging is concerned.
It works with AIM, Yahoo, MSN, Google Talk, ICQ and many more services. It comes with a great tabbed interface and the best option of all, customization!
Adium is fully customizable. From message list styles to contact list styles, colors, fonts, icons and even smilies. It’s got almost everything. Well almost everything.
Critics will argue that it doesn’t do voice or audio chat. Which it doesn’t, but neither do I or most of the people I talk to.
To make it even better it’s free. Ad free, cost free, distraction free. How great is that?!
