If you are thinking of buying a laptop from the apple brand you have to keep in mind that you may be one more affected of the problems that are happening with the second generation butterfly mechanism that Apple has implemented in their latest models of their laptops.
In the network we only have to search for "Apple keyboard problems" and hundreds of affected people appear who claim that the keys stop working and when pressed they have no path and therefore do not make the correct keystroke.
Apple Lossless Audio CODEC (ALAC), wanted to reimagine the keyboard of the brand's laptops so that they are much thinner and thus save space to be able to take advantage of the same space for more battery. This, in theory, works perfectly and surely the same thing has also happened in your tests, but in reality, computers can be subjected to a multitude of unfavorable situations, especially micro-dirt particles that accumulate underneath the keys in the small space that allows the new butterfly mechanism.
Given this problem, we see that a user can spend 2000 euros on a laptop and suffer this problem, being not covered by the brand and is that Apple, To this day he has not given the arm to twist with respect to the arrangements. Are you affected by this problem?
To tell you the truth, on my first-generation 12-inch MacBook I had a good scare a few months ago when half of the space bar did not press at all, after which what I did was tap a couple of times with my palm. hand on the keyboard with the computer face down to let any dirt fall off.
After that everything returned to normal but seeing what is happening I am afraid that in a while it could happen to me again now that the laptop is three years old, which would lead me directly to technical service. Will Apple realize that it really is a problem?
