During the cutting of the new MacBook Pro 2018 by iFixit A silicone membrane or protector was detected between the keys and the butterfly mechanism of the keyboard, and now thanks to the leak of an internal document that was passed from Cupertino to authorized suppliers, it is shown that this Silicone protector is added to protect the keyboard from dirt.
This is not something that we have to confirm again with this leaked document since we all knew that this piece of silicone was in place to protect the MacBook Pro keyboard, but it is confirmed that not only "noise" wanted to get rid of Apple on the new butterfly keyboards this year.
This protector is something that every MacBook will carry from now on
The design of this small membrane will surely be improved and it will be perfected so that the new equipment that is launched during the following batches do not have problems with dirt, at the moment an important first step has already been carried out that obviously in addition to reducing the noise when typing , will help keep dirt and dust from damaging keyboards They have so little travel and any dirt leaves them nailed.
Specifically the internal document filtered says:
The keyboard has a silicone membrane under the keys to prevent debris from entering the butterfly mechanism. The procedure for replacing the space bar has also changed from the previous keyboard model. All the dRepair documentation and service videos will be available when the first shipments of these parts for equipment replacement begin.
In addition, we would not be surprised if those who are having problems with the butterfly keyboard end up changing it for the new model with this silicone protector between the key and the mechanism itself.. This is not something confirmed by anyone, but it would certainly be a very good solution for those who have been affected by this keyboard failure.
