iFixit has got its hands on the 13-inch Macbook Pro with Touch Bar, and did what it does the best, rip it apart to know what it holds within. Comparing it with the 13-inch Macbook Pro without the Touch Bar, there are some significant differences.

To begin with, both MacBook Pros come with same dimensions, but the one with Touch Bar is 20 grams lighter due to the smaller battery. It gets a very poor score of 1/10, highlighting how the device is not easily repairable. Though the trackpad can be removed without first removing the battery, there are just too many sore points. The internal elements have been redesigned in such a way that there is room for the Touch Bar. The flex cable that connected the Touch Bar to the mainboard is wrapped under it and that made removing it all the more difficult.
The iFixit report also pointed out that fixing a faulty power switch will need replacing the entire logic board. “The Touch ID sensor doubles as the power switch, and is paired with the T1 chip on the logic board. Fixing a broken power switch may require help from Apple, or a new logic board, iFixit explains.
Moving to the battery, the report adds that the battery assembly is entirely, and very solidly, glued into the case, thus complicating replacement. Moreover, proprietary pentalobe screws continue to make working on the device unnecessarily difficult. You can read the complete report here.
