How to transfer files from a Mac to an MP3 player?

Mac doesn't recognize MP3 players directly (due to MTP compatibility issues). You'll need a small helper.

Steps:

  1. Download and install OpenMTP (free software): https://openmtp.ganeshrvel.com/
  2. Cable注意事项 (Important):
    ❌ Don't use a USB-C to USB-C cable.
    ✅ Use a USB-A to USB-C cable (one end is the rectangular USB-A, the other is the oval USB-C).
    • If your Mac has a USB-A port: plug it in directly.
    • If your Mac only has USB-C ports: use a USB hub (with a USB-A port) first, then connect the MP3 player with the A-to-C cable.

       3. Open OpenMTP and drag-and-drop your songs like you would with a USB drive.

One sentence summary: Install OpenMTP, use an A-to-C cable, not a C-to-C cable.
