internet connectivity is required for communication between mac with its files from photoshop to a 3d laser printer which uses the cloud for communication even when on the local network. This is not an option for my wife's business setup.

She already uses Linux for everything else.

I am a Linux System Administrator and teach courses on the topic.

Its only natural that she uses linux for everything else.

this was a question about a specific machine for a specific purpose nothing else. Thank you.
