For a native Mac OS X experience we recommend Adium, which uses libpurple (the core of Pidgin) for much of its protocol support. If you’re sure you want to use Pidgin on OS X, you may find the packages provided through Homebrew, pkgin, Fink or Macports more convenient than compiling from source. Explore the world of Mac. Check out MacBook Pro, iMac Pro, MacBook Air, iMac, and more. Visit the Apple site to learn, buy, and get support. Adium is a free instant messaging application for Mac OS X that can connect to AIM, XMPP (Jabber), ICQ, IRC and more. Learn more about Adium.
