It converted fine for me. If you're using an older version of the Toolkit, edit the filename for the cdlc to remove any "." from the filename (other than the extension). For instance, this song's filename is "Scorpions - Rock You Like A Hurricane - v2.1 - DDC v2.2_p.psarc". You need to remove "v2.1" and "v2.2" from the filename. Older versions of the Toolkit can't convert songs with a "." before the extension. Be careful if you decide to update to a newer version of the Toolkit. Several Mac users have had problems with customs converted with Toolkit versions released in January. The songs convert, but don't work in RS. I've also experienced lots of bugs with the January releases of the Toolkit, so I use a slightly older version, which you can find posted here: http://customsforge.com/topic/33889-how-to-add-custom-songs-on-mac/
