"How can I convert WMA to MP3 on Mac OS X?"
I've previously covered solutions for converting WMA to MP3 on Windows, as well as a method to convert WMA to MP3 with iTunes. Unfortunately, the iTunes method that works well for Windows users isn't an option with iTunes on a Mac. To go from WMA to MP3 on OS X, you need to enlist the help of additional software.
Currently the best solution I've found for WMA to MP3 conversion is an app called Switch Audio File Converter. When you get to the download page, you have to scroll to the bottom to choose either Intel or PPC version, depending on your Mac.
In order to make it work, you also need to download Flip4Mac WMV Player, which is a QuickTime plugin. Flip4mac is currently Microsoft's officially supported way to add Windows Media file integration on a Mac for both WMA and WMV formatted files.
Once you have both components installed on your Mac, all you need to do is add one or more files to the application, choose your output location for the files, and convert.
