sounds like its reading the files the usb stick keeps for drivers and the like so when you plug it into a computer it can install and be read by the computer correctly, all flash drives have these and there may be nothing you can do to prevent the cars system from seeing them. not 100% on a mac but you should be able to put the flash drive in a computer and view these files, perhaps delete them and retry, make sure you select show hidden files.
