I have a MacBook Pro (Retina, 13-inch, Early 2015), and since a while the keyboard is malfunctioning. At first the E and D keys problematic, then F and G, and now it's T. To be clear, the others are working normally again. So now it's only the T that is a problem.
Can somebody explain why this happens, how this works, how it will proceed and if I can do something about it now?
This is not the keyboard with the butterfly design, that had so many problems. This keyboard is from before that disaster.
Small update: when logging in, the T does not work at all, so I had to change my password. I tried many things, long hard presses, in each corner of the key. In the end I had to use an external keyboard to login. Now - logged in - the T works more or less.
