The MacBook Finder shows that the USB flash drive is mounted, but it wasn’t showing the files, so I safely unplugged the drive and plugged it again, but it was empty – according to my MacBook or at least what, it seemed to me. Go to Product Repair.“I inserted my flash drive to MacBook Air running Catalina 10.15 to include a pictograph in an excel file, which was very important but nothing happened. If the issue is still unresolved, service may be required.


Try removing the file from the USB drive and saving a new copy. If other files play, there may be an issue with the file itself.A list of the supported file types is available in the operations guide. Make sure that the file being used is one of the supported file types.

Make sure that the USB drive is fully inserted into the USB input of the player.Manuals are posted on your model support page.
