How the heck do you install the new firmware on the 7D? I'm looking at the guide and I"m following it just like it says using EOS Utility. However, in the Set Up menu, I don't have the option to click on the firmware update and the only highlighted section is the Live View/Movie func. set. I'm on a Snow Leopard Mac. I do not own a CF card reader but I'll purchase one if I can't figure this out.
