Howdy,

Assuming you have MacTeX(TeX Live)-2010 installed have you updated everything, not only fontspec? The fontspec package depends upon other packages being up to date too. In this case I'd guess something in the expl3 package group needs updating.

If you're using OS X 10.5 or later use TeX Live Utility to do a full update of everything. otherwise you'll have to use tlmgr directly.

Good Luck,
