3.How to access the storage/SD card after connecting the JM21 to a computer?

For Windows computers, it is driver-free. After connecting the JM21 to the computer by the included USB cable, the driver will be automatically installed. Then the FiiO JM21 disk can be directly seen on the computer.

Mac computers need a driver.

1.After connecting the JM21 to the Mac computer, click the "NO NAME" folder emerging on the desktop->double click Mac->Mac/MAC OS MTP Client->Android File Transfer.dmg. Drag the "Android File Transfer.dmg" to the desktop of the computer.

2. Drag the "Android File Transfer" file to the "Applications" folder and wait for the completion of the copy.

3. Enter "Applications", and double click the "Android File Transfer". Then you can manage the files stored in the internal storage of the JM21 or the Micro SD card.

Notes: The JM21 folder will directly pop up the next time it is being connected to the same computer.
