So I was confused at first, until I realized the headline said "Mac Pro", not "Macbook Pro".
Plenty of professionals use MacBooks, Mac Minis, and even Mac Studios.
The question is, who wants the new Mac Pro? The vast majority of professionals are better suited by a laptop, or can get all the same work done with a Mac Studio.
I would think this would probably be more useful for people involved with video production or animation than music production, which could likely be accomplished on a MacBook.
