Need to press power button to wake?
After upgrading to macos Sierra, I need to press the power button on the computer to get it to wake up after sleeping. Just pressing a key on the keyboard does not wake the computer.
I'm seeing this behaviour on these two machines:
* MacBook Pro (Retina, 13-inch, Early 2015)
* iMac (27 inch, Late 2009)
I'm guessing this is not the intended behaviour?
