Apple is selling two new computers that it's calling MacBook Pros: one model without the new Touch Bar and one model with a Touch Bar. But according to a teardown of the Touch Bar model by iFixit, the differences don't stop there. The Touch Bar has an entirely different motherboard, cooling system, and internal layout. Unfortunately some of those changes make it even more difficult to repair than its cousin.
The Touch Bar MacBook Pro has a much larger cooling system than the non-Touch Bar model—it uses two fans instead of one, and the symmetrical and vaguely mustache-shaped logic board wraps around both of them. The odd layout (plus the need to make additional room for extra chips like the Apple T1 and the second Thunderbolt 3 controller) leaves less room for other things, and as a result Apple has soldered the SSD to the motherboard in the Touch Bar MacBook Pros, much as it has in the 12-inch MacBook.
