My keyboard has gone haywire on OS X El Capitan. What's going on here?

Keyboard-bug-el capitan-0

Since the appearance of OS X El Capitan a couple of months ago, there have been a series of bugs and incompatibilities with the software coming from Yosemite that made Apple quickly release small updates to the system that improved performance and in turn could solve the problem. situation as much as possible. Specifically I mean errors in Spotlight indexing, a Microsoft Office 2016 suite or in user accounts.

However, until now there has been no talk of a problem that is increasingly being Most commented on Apple support forumsI am referring specifically to a bug that causes the keyboard to start typing "alone" without the possibility of stopping it.

The positive part is that this problem is reproduced in a very specific situation, when the system returns from inactivity Having been idle and the login screen appears with the user password, if we press any key without waiting a few seconds, the keyboard automatically enters a kind of loop and begins to write alone. In this situation, it is impossible to enter the password and access the session to restart the computer and the first few times it would turn off the Mac directly by holding down the Power button.

This failure reached such a point that I even raised the heavy task of having to reinstall the entire system in case it was a particular failure that it was only happening to me…. Meeeecc!… Wrong !. Investigating a little more on the Apple support website and more specifically in the forums, I saw that there were more users with this error and from what you can see it has nothing to do with a bad installation of the system, but with a conflict in the bluetooth protocol with OS X (only occurs on wireless keyboard).

After multiple tests, the error is reproduced only on those computers that have the Apple wireless keyboard and Magic Trackpad, arising a conflict between the two that makes the keyboard happen this. The solution for now is to remove the batteries from the keyboard or restart the Mac, hopefully Apple can fix it quickly, since although not critical, it is a rather annoying bug.

    Hello, a few months ago, at the beginning of El Capitan, I told Jordi Gimenez that he had this problem with the keyboard. The solution that I apply to avoid removing the batteries or resetting the computer is simpler: you just have to turn off the keyboard (3 seconds by pressing the button) and reconnect it (button pressed 3 seconds).
    regards

    The same thing happens to me but with both the wireless keyboard and the usb keyboard. Start typing only both on the login screen and in any application. I changed for a common usb keyboard (from pc) and it does not do the problem. Any suggestion?
