Yes! I had this same problem on mine, you have to change the usb into storage mode only and the sd card will show up on the desktop then you can load music files pictures anything you want into the card. for the charging issue i noticed only 1 of the 2 usb ports not charge the phone try switching the cord into the other usb port... hope this helps you.

 

drop the notification window down, it's right there bro.

 

FWIW, Tunesync is a Godsend for Mac and DroidX users when it comes to iTunes. I can copy over my playlists using wifi, no cables or anything.

 

This is what I do when connecting to my MB. Plug cable into phone, plug into MB. A window will popup on the MB screen saying this disk cannot be recognized or something to that affect. Click go away.

On the X, I drop down the notification panel and there are like 3 options. Pick usb storage. I then click my MB finder icon and there is the no name disk on the desktop.

 

Has something to do with the Nigerian detection software.

 

For me the X only mounts sometimes. If I try to connect to my MBP and it won't give the the connection notification I have to reboot the phone. Once rebooted it will connect and mount but it's kinda frustrating to have to reboot the phone everytime I want to add some tunes or a movie to my sd card.

 

Apple and Motorola just don't like to play nicely. I am thinking about purchasing a Macbook Pro but am a bit hesitant. I wish they would offer a full refund.
