MacBook Pro (Late 2011), OS X 10.10.4.
Increasingly Mail.app (Ver. 8.2) and Chrome (Version 43.0.2357.130 (64-bit)) do not allow me to type the rest of my input.
This evening it happened and was able to take this 9 second screen capture. (YouTube Link).
You can see that despite furious typing (shown on the Keyboard viewer) I simply cannot type the rest of my sentence.
Switching apps with alt + Tab, however, works fine.
Where do I begin to investigate this?
Still to try:
• Replicating under safe boot
• Replicating with different user
• Resetting PRAM (or whatever it is called nowadays)
Who can help?
