Apple’s reengineered thermal architecture includes fans with redesigned blades. While medium to high frequencies are indeed pushed through the grille holes from a tweeter located underneath, low-bass sounds are directed through the long air intake vents under the left and right sides and reflected on the surface of the desk. Like its 13-inch variant, the 15-inch notebook’s speaker grille holes are mostly for symmetric styling and don’t go all the way through. The trackpad on the 15-inch MacBook Pro with Touch Bar is twice the size of its predecessor and it’s so large that Apple had to throw in an extra Broadcom touch controller integrated circuitry to handle all of that extra touchable glass. Other notable findings from the teardown analysis: The same connector was found in the 13-inch MacBook Pro with Touch Bar. We’d still rather see a removable/upgradeable SSD, particularly in a machine targeted at pros-but this way if your logic board bites the dust, there might at least be a chance of recovering your data with Apple’s help. “Not a bad idea when it’s impossible to physically salvage your data out of a damaged machine.” “Based on our previous teardown, we’re speculating Apple included an access port for the integrated SSD,” explains iFixit. Like on the 13-incher, this machine’s processor, RAM and flash memory are soldered to the logic board, meaning that the SSD is impossible to remove or upgrade.Ĭuriously enough, iFixit has discovered a hidden connector inside the machine that leads “nowhere,” speculating it could be for SSD data rescue in case of hardware failure. Comparing the two Touch Bar-equipped notebooks to the 13-inch MacBook Pro without Touch Bar, which iFixit also disassembled, the repair site has confirmed that only the baseline 13-incher with a standard row of function keys has a removable SSD. 
IFixit on Friday published its teardown analysis of the 15-inch MacBook Pro with Touch Bar (model number A1707), just two days after taking a peek under the hood of the 13-inch MacBook Pro with Touch Bar.
