MAC iChat is the default IM program for the mac and should already be installed on your mac. (A benefit is that you can share your screen and/or trouble shoot with another mac user)
Adium is a substitute if you do not like iChat adium.im/
PC Pidgin is the recommended IM program for use on campus www.pidgin.im/
