I want to buy a used MacBook on eBay for school (and uni since I have one year left in highschool), beginner music production, programming, and web browsing. And I am looking for MacBooks between 1500-2000 BRL, but don't know which model to chose. I have been interested in 15" 2015 MacBook pros, but I'm concerned about software support, and heard pretty bad things about butterfly MacBooks, so I don't know what to chose. Any help?
