Questions about Intenso premium edition

I'm not sure if it's a good idea to use a USB port on your Mac, but it's a good idea to use a USB port on your Mac, and yes, the SSD will appear on your Mac's desktop.

There won't be much you can do, because the enclosure contains an SSD. Theoretically, you could break open the enclosure and try to install the SSD in another enclosure.

In general, the principle that a copy is not a copy applies to everything you accumulate yourself and the 3-2-1 backup concept must be implemented consistently, 3 copies on two different systems and one copy in a different location, so that you at least have the possibility to get back to the data if something goes wrong.

Yes, you can.
