2012 mbp - slow wake up from sleep after last mbp update

Have you figured anything out yet? I have this exact same problem, the grayed out screen and verticle bars, with my Macbook Pro 13 inch mid 2012 non retina. It never did it when I first got it and even after i installed OS X mountain lion. It just recently started maybe a month ago.

There have been issues with 10.8.2 and retina displays.

Try looking for posts on this issue in the 10.8 Usage forum.

Hi AldousH,

Did you find a solution to this problem? I am also having this exact problem with the grey loading screen and the error when trying to reinstall 10.8.2. I tried both the combo update and the non combo update, both cant be installed.

My old macbook used to wake this way when the battery had been empty. But my late 2012 macbook pro 13" is just about always connected to power, so that can't be it!

I hope you (or someone else for that matter) has found a solution to this insanely annoying problem!

I have been having this problem too since an EFI update, not 10.8.2. Every time I wake up my MacBook Pro after hours of no use it makes this weird noise (sounds like the hard drive), and takes forever to wake up. I noticed that if I unplug the MagSafe before I open my MacBook Pro I hear the noise and when I open it wakes up quickly. I still don't know what the problem is and I would like it to be resolved either way.

Ok so I've been doing some research and messing around with some settings. If you go into Terminal and type pmset -g your current sleep settings will pop up. This is what I currently have mine set to, and it has solved my problem (the problem causers are in bold):

Active Profiles:

Battery Power -1

AC Power -1*

Currently in use:

standbydelay 9000

standby 1

womp 1

halfdim 1

hibernatefile /var/vm/sleepimage

sms 1

networkoversleep 0

disksleep 10

sleep 10

autopoweroffdelay 43200

hibernatemode 3

autopoweroff 1

ttyskeepawake 1

displaysleep 10

acwake 0

lidwake 1

I was messing around and trying out different things and I believe the problem is the "standbydelay" setting, when on battery power. I changed it to 120 (which is in seconds) and let my Mac sleep for 2 minutes. At 2 minutes, the flashing light (sleep light) went off. I opened up the Mac and got the gray screen w/ progress bar. I did it again but this time on AC power and this did not happen. So I changed "standbydelay" to 9000s (2.5 hrs) and changed the "autopoweroffdelay" to 120 seconds. With the Mac plugged in, I shut the lid and watched it sleep. At 2 minutes, the sleep light went solid, then shut off completely. When I opened the lid, I got the gray screen with progress bar. So I then tried it again on battery power, the sleep light stayed flashing past the 2 minutes. I opened the lid and it woke instantly. Just for good measures, I tried it again, let it sleep on battery for 2 minutes, still constant flashing. But then I plugged it into AC power and let it sit for another 2 minutes. At the 2 minute mark, the sleep light went solid and then went out completely. Opened the lid and got the gray screen and progress bar.

From what I've read, what is happening here is the the contents of the RAM is being copied to the hard drive, which will save any apps/content you currently had pulled up before sleep just incase there is a power problem. When you power it back up, or wake it up, the hard drive has to rewrite the contents of the RAM back to the RAM which is why it takes such a long time and you get the progress bar. It also is a power saving mode that allows the Macbook Pro to sleep for longer and uses less power.

To change these settings, type in:

sudo pmset -a standbydelay 120 You can type in whatever number you want

or

sudo pm set -a autopoweroffdelay 120 Again type in whatever number you want.

Although I haven't tried this yet, but I believe if you do not want this to happen at all, all you have to do is set "autopoweroff" to 0 or "standby" to 0.

Hope this solves the problem for you!

Hi Debra, thanks for your detailed update. I am glad i am not the only one here

I just want to clarify for pmset; standby refers to battery mode and autopoweroff for charger plugged-in mode?

Yup that is correct

I am new to mac, my MacBook Pro (non-retina) is just 2 months old - Recently updated to 10.8.2.

I did not changed any settings in the pmset; my standby is 0 and autopoweroff is 1.

Everytime when i leave my macbook to charge over-night, i know it goes to deepsleep/hibernation because the next morning the sleep indicator light stops blinking and when i pressed that spacebar to startup i could hear the dvd sound and the progressive bar starts to move.

All this does not happen when is on battery mode, it wakes up in an instant.

I spoke to apple support and they suggested that it is not recommended to change anything inside the pmset.

Can you please tell me exactly what I should enter inside terminal??

"sudo pmset -a autopoweroff 0" or "sudo pmset -a standby 1"

Thank you.

Just like you I noticed that my Macbook won't hibernate when it is on battery power, which seemed odd, so I looked a bit further:

Using the "pmset -g custom" command I looked up both the ACpower and Batterypower profiles:

Macbook-Pro-rjdw:~ rjdewerk$ pmset -g custom

Battery Power:

lidwake 1

autopoweroff 1

autopoweroffdelay 14400

standbydelay 4200

standby 0

ttyskeepawake 1

hibernatemode 3

hibernatefile /var/vm/sleepimage

displaysleep 3

sleep 10

acwake 0

halfdim 1

sms 1

lessbright 1

disksleep 10

AC Power:

lidwake 1

autopoweroff 1

autopoweroffdelay 14400

standbydelay 4200

standby 0

ttyskeepawake 1

hibernatemode 3

hibernatefile /var/vm/sleepimage

womp 1

displaysleep 10

networkoversleep 0

sleep 15

acwake 0

halfdim 1

sms 1

disksleep 10

What I noticed is that the only difference are the times at which the machine sleeps. The hibernatemode and standby settings are the same.

This means that the sleep behaviour should also be the exact same under both power conditions. The fact that this is not true means that the problem is not with the power profile itself.

In short: editing the power profile settings using pmset can work around the problem, but it is by no means a fix.

@egsl: I do not know which setting you need to edit, for that I hope someone else can jump in.

I sent a bug report to Apple using the OSX feedback page with links to this and several other threads describing the problem. I hope they release a fix soon!

Could somebody help explain what is the difference - "standby" and "autopoweroff"?

@Sleg5, from the tests that I ran, "standby" is for when the computer is on battery power and "autopoweroff" is when it is on AC power.

@egsl, if you want to keep the "deep sleep" mode, or whatever it is called, on battery power, then you will need to have standby at 1, and change the standbydelay to the time you want it to go into this mode. So you will type

sudo pmset -a standby 1 and hit enter, it might ask for your password, then

sudo pmset -a standbydelay (whatever number)

if you want to turn it off on AC power, type

sudo pmset -a autopoweroff 0 you shouldn't have to change the delay bc the setting is at 0

@jognt, I did the pmset -g custom and here is what I got:

unknown1040f3f0c406:~ trevorh17$ pmset -g custom

Like you said my settings are listed the same for AC and battery. But when I ran my tests as I explained in one of my previous posts, autopoweroff seemed to apply only for AC and standby only for battery. I've been a few days with it now and it no longer goes into that deep sleep unless I let it sit for the amount of time I designated in the standbydelay/autopoweroffdelay. It would be nice if Apple could explain these settings somewhere though

That's the thing. Since the settings are the same it should work the same. The simple fact that it doesn't means that these settings are not the root cause. The cause seems to be that the power profile settings are not interpreted right. That's what I mean by saying that editing these settings will work around the problem, because the problem is in de interpretation of these settings, not the settings themselves.

Anyway, Apple does explain a few details about the PMSET command on the developer pages at:

https://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages /man1/pmset.1.html

The reason why I say that the interpretation of the power profiles is broken is because the standby and poweroff arguments in de power plan are used in accordance with the "hibernatemode". Hibernate mode "3" means that the system will stay in standby, and will send the content of RAM to the disk and hibernate only when power is running low.

For some reason, when the power cord is connected, the system ignores Hibernatemode = 3 and suspends to disk anyway. Editing the time it requires to hibernate, or telling it not to hibernate at all will work, but it won't fix the issue that the hibernatemode is not interpreted right.

I understand what you're saying now, good point. I've come across that link that you posted before but there is no explaination for autopoweroff on there. I've been searching for what it is supposed to do but I can't find anything.
