Use All2MP3 - download here.
You can also use the online media conversion tool
Note: if you were previously using Switch+Flip4Mac this stopped working under 10.6

10.5 or older:

All2MP3 - download here.

Using Switch with Flip4Mac. You'll need to install both to convert WMA files. Note: As of Dec 2009, there is a conflict between the latest version of Switch and Flip4Mac causing it to crash while trying to convert wma files. Make sure you use a previous version of Flip4mac 2.2.3.7 seems to be working.

Once installed (or if you're in one of the campus' computer labs where these applications are already installed):

Drag your .wma file into Switch
select the output format that you desire from the drop down menu (i.e. .wav or .mp3)
Pay attention to the output folder. This is where your converted file is going to be saved
highlight your file in the main window and select Convert

Online Media file conversion

If none of these works for you there's always mediaconverter.org, a handy, free site where you can convert media files to and from almost every useful format. It's a bit slow, and you can't do batch conversion, but it'll work in a pinch.
