I'm on a July 2014 macbook pro retina 15". I use multiple monitors. Sometimes in the morning when I open my macbook from sleep, the screen is backlit, but black and not showing anything, and I can't get it to wake. (Not sure if this problem has to do with multi-monitors, or not). I'm forced to push the power button for a few seconds until the computer turns off. Then when I turn it back on, it says that my iCloud keychain has been reset. And I have to do the annoying steps to enable it again (enter two passwords, and type in a code sent via SMS to my phone.)
This is pretty annoying, any ideas?
