MAC OS is not recognizing my music card!!!

Hi

since yesterday my macbook is not recognizing the music card, i didnt have any trouble before, i update the firmware to the last one available but nothing happened.
Does anyone know what to do???
is there any way to add the driver to the mac??
thanks

Hi and welcome to the MeizuMe Forums! So it worked before with your Mac? If so, try using the old firmware you had before you updated, that might work, or try your player on a PC first to make sure nothing is wrong with it.

i don't have a mac but i have a friend which have the same problem the m3 isn't recognized since leopard 10.5.2 you should be on tiger 10.4 for getting working the m3 it's possible to create a partition on leopard with an old version of itunes and you will be able to synchronise your player with this old version of itunes and the plugin "iTuneMyWalkman"
a french guy has given this solution but i don't have more info to explain you how to create the partition hope it's help .

thanks for both replies, ill try to restore the firmware
