Typically after being closed for a few hours, overnight, etc, I open the laptop and get this horrid grey screen for probably 5 minutes. When it does come back the UI is locked for another minute or so. Why would it decide to start doing this only recently?
I've checked hibernate mode, which was set to 3. I changed it to 0 and that made no difference. Still grey screens me every morning.
MacBook Pro (13-inch, Mid 2012)
2.5 GHz Intel Core i5
16 GB 1600 MHz DDR3
Intel HD Graphics 4000 1536 MB
Disk space is about 50% used. Battery fully charged and still in good shape. Laptop is pretty much always plugged in. Full charge lasts all day, so I don't think it's a power issue. I have clean my mac constantly profiling the machine, which reports not even half RAM usage at wake up, and across the board very low consumption.
Starting to get pretty annoying. It never did this until recently, about 4 months ago. I usually keep my OS a version behind on purpose, fyi. Anyone else know what this is and how to prevent, disable, or correct it?
