MacBook Pro keyboard failing after 10.10.4 update
Hello,
I've had some problems today after updating my MacBook Pro (Retina mid14) to OSX Yosemite 10.10.4. First of all, a few days ago I tried to download and install this update, but for some unkown reason I wasn't able to complete the action (some strange error came out). I had no results after some attempts, so I left it.
Today morning it has automatically updated itself, after rebooting everything seemed to be okay. But after an hour using "the new version", the keyboard freezed completely for all apps. Every key that used to type a character didn't work. I could use, though, all the function keys. Then I tried to open spotlight, and I was able to write in Spotlight search without any problem.
I have then rebooted my laptop (the trackpad and system were working normally), and after that the keyboard worked again. But 5 min. ago, after resuming the macbook (opening the lid), it happened again.
Does somebody have any clue of what could it be?
More details: I think that I had a display through VGA and a USB3 external drive connected at those moments (I'm not sure, but I have them almost always connected).
MacBook Pro (Retina, 13-inch, Mid 2014), OS X Yosemite (10.10.4)
