Actually, if we look at the competition, there are already some brands that are using protection to prevent the entry of liquids, dust or dirt into the equipment. This is something that Apple does not have on Mac keyboards and it would be without a doubt a real advance.
Liquids and electronic components do not get along even though we have protection before them, but in the case of having a resistant certification against the possible entry of liquids into a keyboard, it gives us peace of mind. It is true that this can lead to problems in the future since Apple does not take care of the entry of water into a computer even though it is "resistant" to liquids.
Unfortunately we all have cases of friends, acquaintances or we have even had our own experience with liquids on a Mac and it is not pleasant at all ... Keyboard input is a problem and the new Apple patent shows the possibility of separating the keyboard of the rest of the team and this would be great for liquids, dirt and so on.
In the patent you can see the system that would be used to prevent the entry of liquids or dirt from the keyboard, a kind of direct closing of the keys, something that would really help us to avoid problems:
Patently Apple, shows the patent that could be really interesting for Mac users and that we hope can be implemented as soon as possible to avoid damage to our expensive equipment. Obviously it is just a patent and we already know what happens with it, Apple can use it or not, but in this case it would be very good if they implemented it in MacBook.
