Sansa clip came partially charged from retailer. Worked fine as UMS when plugged into a Mac G5 OSX 10.4.11,and accepted drag and dropped mp3 files into the music folder without problem; only FM radio had no sound (normal sound with music). Clip was exchanged for another unit.
Replacement came uncharged; connected to USB port and Clip showed ‘connected’ with display animation graphic. Device showed up appropriately as USB disk on Mac desktop. After a couple of hours, ‘USB disk’ was dismounted by dragging to the Mac trash (no attempt had been made to drag any music file to the Clip). After disconnecting from computer, Clip was turned on, display lit up with SanDisk logo, but all controls were frozen and unresponsive, unit could only be turned off by holding the off switch for 15 sec. Restarting met with same result. Also did not maintain charge after a couple of restarts. On reconnecting to USB port only splash screen showed, no ‘connection’ or charging indicator.
Though official support is for PC and not Mac, the first unit was able to function as UMS (MSC) device. I am accepting of the fact that I will not be able to utilize the playlist, artists etc. but had hope to use the MSC mode. Had a Creative ZEN-Plus, also PC designated, but worked fine as a UMS.
Any helpful suggestion would be welcome. Would hate to have to give up the Clip for a Shuffle!
