So here are the instructions after a few days of mucking around:
Option 1:
If you use iTunes to store and play MP3s you can make a CD directly from iTunes.
- Make sure you have set iTunes to Burn MP3 CD and not Audio or Data CDs.
Preferences; Advanced; Burning; MP3 CD
- Then select a playlist and click BURN in the top right corner. Check out this document if you want the songs arranged by Artist or Album:

Option 2:
If you don't use iTunes or want the songs ordered in folders you can use Toast software.
- Select Data CD, then select the files and folders you want on the CD
- Select Settings and make sure it is set to CD-ROM; Allow Macintosh Names
This will make a MP3 CD with all the songs arranged in folders so you can choose them easily with the M5 user interface. Just like the MP3BR software for Windows.
Have fun!
