I have been having a **** of a time with OSX10.11 and a Macbook Pro (circa 2014) waking from sleep. About 90% of the time, if it goes to sleep when the lid is closed, when it wakes one of two things will happen. 1) most often, the login screen will appear, cursor blinking, sounds, etc, but the mouse and keyboard, either internal or external, are frozen. Only the power button will work to force a shutdown. 2) occasionally, the screen will appear as though I'm looking at a second monitor at the login screen (I see only frosted background, no login prompt). If I blindly type the password, it will log in, but I can't swipe to switch screens or bring the mouse over to the screen. I can use command key combinations to force a restart. I've scoured the logs. It looks like a lot of crap is happening on wake, but nothing obvious. I've also had to reset the NVRAM a couple of times because I only get a black screen on boot, no sound. Is any one else having similar issues?
