Earlier this week, Apple refreshed its MacBook Pro series, which improved performance with the latest Intel processors, but made no other significant changes.
Apart from one: There is now another revision of the infamous "butterfly" keyboard mechanism, using new materials to further increase reliability. To keep up with this new design, the Apple expanded the repair and replacement keyboard to include almost all Mac laptops with the butterfly keyboard (including the new ones), offering free repair for up to four years.
What's new? The reliable tinker on iFixit has torn apart the recently revised 2019 MacBook Pro. While the rest of the laptop is almost identical to previous models (it serves a terrible repairability score of 1
Sleuths on iFixit noticed two changes to the materials in the keyboard. First, the transparent switch cover is now clearer and smoother to the touch. It is definitely made of another material, as confirmed by FTIR spectroscopy. Second, the metal dome that compresses and bounces back when you press the key can be slightly revised. This metal dome is like pushing on a bottle cap, and if it cracks or bends or contacts wear out, the key will cease to function properly.
Another finish of the coup companies may mean that "Apple may use a revised heat treatment, or alloy, or possibly both," as iFixit explains.
It is not clear if these changes will fix the infamous reliability problems with the butterfly keyboard, but they will not do anything to affect the other issues people have with the keyboard: its short throw and noisy operation.
