The WMA audiobooks can never be downloaded to a Mac or directly to any mobile player, phone, or tablet. All WMA audiobooks must be first downloaded to a Windows computer. The Windows computer contains the "key" to "unlock" the DRM (Digital Rights Management) of the WMA title. Note that Windows users with an Apple device can transfer WMA audiobooks to the iPod/iPad/iPhone.
