Apple had implemented a silicone membrane between the 2018 MacBook Pro keys and the keyboard base. This protection, although Apple did not confirm it officially, served to better protect the bottom of the keyboard and prevent small particles from imposing its perfect operation.
Apple officially indicated what measure was taken to improve the sound of the keys. Be that as it may, this solution It has not eradicated stability issues from Apple keyboards, although we did find fewer incidents in relation to the 2016 and 2017 models. Something I have improved, but it is not enough.
On this same website, we anticipated the problems that began to arise in the 2018 models, a month after starting their commercialization. This time, it seems that the problems are centered in the space bar. These last hours we have known the publication of the page Outline, This post brings several user complaints showing their discomfort with keyboard operation from your new Mac.
Apple seems not to have fixed the problem. Proof of this is the keyboard replacement program If it presents a problem of this style, during the first four years of the Mac's life. If you have the Mac from 2016, 2017, or 2018, you can go to an Apple Store or contact Apple for a free replacement of the keyboard, which includes changing various parts of the Mac.
Some intermediate solutions were to use a bottle of compressed air to release the speck of dust and avoid a major intervention in the part of the Mac keyboard. When it perishes, this solution is no longer valid, since these small objects get caught in the membrane of the keyboard. Still, they do not stop occurring in a limited number of users. Therefore, a correct care of the Apple keyboard does not guarantee to avoid the appearance of these problems, but it does contributes to proper operation.
