A few days ago, iFixit started a teardown of the new MacBook Pro 2018 in which the folks discovered a silicone membrane under the keys of the keyboard. The site believes that the coating is an ingress-proofing which prevents the keys from seizing upwards when in contact with small particles. Now, the complete teardown has been finished which reveals quite a lot of new aspects following the new MacBook Pro 2018. So let’s check it out in a bit more detail.

A few other tidbits revealed narrow down to internal variations in terms of hardware, repositioning of components and battery size. As to begin with, the new 13 and 15-inch MacBook Pro models now feature a bigger battery. iFixit has revealed that the machine now features a larger 58wh battery, coming in at 232.7-gram integrating 6-cells in the smaller variant. The change is up from 5-cell battery coming in at 196.7-grams. Despite the bigger battery, the overall weight has not changed, nor has the battery life. Apple has “shaved some mass” from the top case of the device.
