The updated MacBook Pro 2018 has changed not only the hardware, but also the entire keyboard unit.
After removing the keys, we managed to find out that a silicone substrate appeared under the buttons. Judging by the reviews of the newly baked owners of the new MacBook Pro, the keyboard has become much quieter.
But the main reason for such an update Apple reveals only in the internal document, which is available exclusively to representatives of service centers.
And the technical note itself warns repairers of certain difficulties when replacing keys.
Under the keys there is a membrane that prevents debris from entering the butterfly mechanism. The procedure for replacing the space bar has changed. Relevant documentation and videos will appear immediately after the start of supply of components.
Be careful not to damage the membrane during replacement. Otherwise, you will have to completely change the top case.
So, the reason for the appearance of a new keyboard in the MacBook Pro for the press and buyers according to Apple: the desire to make it quieter.
For representatives of service centers: protection from dust, crumbs and other debris. The fragile “butterfly” mechanism for hitting such objects simply does not withstand.
PS The third generation of keyboards with a butterfly mechanism is a feature of new mabuki. It will not be placed in the model of 2016 – 2017 under the replacement program . Draw your own conclusions. [ MR ]
