The Clip can be set into two modes: MTP (music device) and MSC (thumb drive). A computer can only see the files from one mode at a time. By default, the Clip is set to Auto-Select mode: it will try MTP mode first and then fallback to MSC. So, depending on which computer(s) you connect it, it may use a different mode each time.
In the Clip menu, try going to “Settings > USB Mode”, select “MTP” and connect to your Mac. The Clip should show up as a device and you can check its files. Then disconnect, go back to “Settings > USB Mode” and select “MSC” mode this time. When you reconnect, the Clip will show up as a simple thumb drive with a different set of folders and files.
If all that doesn’t help, you can also try a Format from the Settings menu to delete everything.
EDIT: I don’t know if it’s relevant, but I found this message from a Mac user with a similar problem. Seems that the Mac stores some hidden files starting with “._” .
