Last week i got back my Macbook Pro 15 2016, after 10 days. The laptop go to service on an Apple Technical Assistance here in my city.
My first Macbook Pro (Mid 2012) works for 5 years without issues.
The first problem was the speakers. Sound was horrible. The problem is the same described on this link.
The second problem was the battery. With only 86 cycles a message about to service the battery appears.
The third problem was #staingate.
Apple replace all parts of my Macbook. The service is ok until now.
Lots of problems with this expensive machine. The quality is not the same anymore.
