Mac OS X
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 Fink or Macports more convenient than compiling from source. Please note, we do not provide support for issues related to installing Fink, Macports, or their packages of Pidgin. Contact those projects directly with questions or concerns.
If you're sure you want to use Pidgin on OS X and you don't want to use Fink or Macports, you can download the Pidgin source and compile.
