Q - Description of the product says you can use it on an apple computer, well you can't get an app on the app store in the United States so now what do I do
A - Hi! Thanks for the question. It does help to have the app and make the process smoother! But you don't need the app.
When you plug the device into the USB-A or USB- C ports on your apple computer, it is not necessary to have an app to use it. You would treat it like a normal external memory device and download it straight onto it.
