macOS mounts sd card as internal storage

[Michael Blickenstorfer]

Hi Geoff

First of all, thank you for this awesome script. It's simple but a good start for my project.
Unfortunatelly, I discovered that my mac book mounts the sd card as internal storage, whereby diskutil list external is not showing up any sd card.
As I saw in one of your screen shots, you are using this script on macOS too. Did you make any changes regarding the mount procedure? Or is there some sort of hack?

Thank you in advance!

Regards,
Michael
