From what I can tell, the SanDisk Sansa player is supposed to be supported on Mac OS X. SanDisk has a special forum dedicated to the Sansa, and has a subforum for Mac and Linux. You might want to post your question there if you have difficulty getting your Mac to recognize the player.

If only the latest firmware version causes problems, I'd think it is safe to assume that the problem should be corrected in future firmware updates.
