Hey everyone, I have a mid-2012 cMBP 13" base model with 16GB ram. Recently, when waking from sleep for an extended period of time (more 4-5 hours), I've noticed that when the login screen appears, there is a transparent grey overlay with a progress bar. The machine is slow to respond, and the hard disk will grind during this time. It seems like the ram contents are being restored from the hard disk. It's kinda annoying to have to wait for the machine to respond before logging in. Is this normal behavior? I've only noticed it after recently installing the system update released a few days ago.
