Can I use a Mac OS X system to prepare the contents of my SD card?

Yes, but you must delete the hidden system files (.DS_Store, etc.) generated by Mac OS X.

Follow these steps to prepare your SD card correctly.

Detailed procedure

1. Insert the storage device into your Mac.
2. Format it to FAT32 and give it a volume name.
3. Copy your files and folders onto the storage device.
4. Open Terminal (Applications -> Utilities) and run the command: dot_clean -m /Volumes/(volume name)
5. Eject the storage device by following the system’s eject procedure. 6. Switch on the player with the storage device prepared in this way.
