It sounds like you're trying to download the firmware update from the Yamaha website and drag it onto your USB stick. If that's the case, this might be one of those rare situations where your Mac isn't recognizing the USB stick due to its format.
While it doesn’t happen often, Yamaha does recommend using a different USB stick for the firmware update just in case the one you're using isn't compatible. If you can, try using another USB stick specifically for the update — that usually solves the problem.
