Your battery was probably so low that the system wrote out your memory contents to disk so that the lack of power wouldn't cause the memory contents to disappear. What you're seeing on the screen is your Mac returning the contents to memory from disk.
It's quite normal behavior![]()
System was connected to the mains power and battery was full, I am worrying a bit because I have just put new ram in it and am looking for errors.
Did you put the new ram in while it was still asleep?
For what it's worth, I had exactly the same thing today.
Usually my Mac resumes from sleep in a couple of seconds.
Today when I came home (it had been sat on the desk at home, on mains power all day but asleep) I opened it up and it took about a minute to resume properly, complete with spinning beach balls.
Last night when I put it to sleep as per normal, was the first time I put it to sleep *after* installing the 127MB update Apple pushed to my mid-2012 MBP yesterday. Whether that is a coincidence...
I'll try it again later and update this thread!
OK - an update - I put my Mac to sleep, left it for a few minutes asleep (with the 'sleep' light pulsing, as normal) then opened it up, and it woke from sleep in a few seconds, as per normal.
I can only assume that the initial - lengthy - resume was something to do with the update yesterday.
But now, it seems, normal service has been resumed!
On Sunday calibrate my battery, so I completely emptied. On Monday I connected the computer and used it for an hour, then closed the lid and fell asleep for half an hour. When I opened the lid again, had the behavior you describe (as seen in your picture).
Do not know what has happened, I have not added memory or I made changes to my mac. By the way, I saw that Microsoft Silverlight is installed but do not know when it was added, and do not know if this is related.
This is how the mac wakes from hibernate. Usually the system won't hibernate by itself but there is software out there that can change it so that it will hibernate instead of sleep or hibernate after sleeping for a certain period of time. You can also change it with terminal commands. Is it possible that you changed a setting via software or terminal?
No, it's just resuming from hibernation.
As per my earlier post, my MBP *after* the "Update 2.0" did this, then went back to behaving as it previously had - that is, resuming in a few seconds.
However that seemed to be because I was "only" sleeping for short periods of time.
Having done some more testing, I see that if I let it sleep overnight, or for a few hours, it now *always* seems to fully hibernate, and this takes ~1 min to fully come back to life.
This is NOT a problem, now I know what (and when) to expect it.
But this IS a change to how the system previously behaved, and it's only started happening since "Update 2.0" was installed.
(Note - I've not changed any other settings, although I did try setting "Sleep" to "Never" when on "Adapter" power, but that changed nothing, my MBP still hibernates after a few hours' sleep!)
