Mini Mac for Cubase?

Hi, I currently use Cubase Artist 10.5 on a HP PC. I have a friend who is looking to do some collaboration but due to a lack of confidence on his part insists on using Garage Band on his Mac.

I have an editors keys keyboard and a decent monitor, so am considering buying a refurbed Mini Mac - maybe the M4. I’d then use this as my main machine for my own, Cubase, projects.

Would this be a good solution?
