Power Nap and Late 09 iMac

Hi,
I am confused atm. I was told that only computers with SDD and being the latest models support power nap on ML however I have noticed that ever since updating my iMac apprears to wake all the connected HDDs up at inverals of 2 hours to start a TM backup. This has become quite annoying as it does it at night when asleep and at times wake me up.
It can't be Power nap but it seems to act like it and I cannot turn it off.
Any help would be great thanks.

  • No Power Nap option Late 2011 MacBook Pro

    Here is what the specs for Power Nap say:
    Power Nap
    Supports MacBook Air (Mid 2011 or newer), MacBook Pro with Retina display.
    Does that mean that Power Nap is not supported with my Late 2011 MacBook Pro?

    I was reading that it is because one of the requirements is flash storage, , so I don't think it will be coming in an update. I have a Feb 12 MBP and probaly won't get the upgrade either.
    I had read that too. Fortunately, I meet that requirement. I have one of those expensive Apple SSD's. So that was not my problem. Sadly, I just don't have the right hardware for this feature.

  • Power Nap and Safe Sleep "incompatibility" will KILL your SSD ?!

    Hi!
    This is a common pmset -g output from a ivy bridge Retina 15':
    Barfly-i7:~ syd$ pmset -g

    PREAMBLE:
    I was trying to figure out (like many others on the net) the real difference between "standbydelay" and "autopoweroff delay" and I made some test that showed something that could be a SSD-Killer bug for many mac owners. (please note: I still don't fully understand why you need the 14400 delay if the standby one comes firsts and does same thing). (note 2: Mr. pmset man page editor, is very "funny" to read  "For your sake and mine, please don't use anything other 0, 3, or 25." in an official man page but you are not explaining the relevance of bits 3 and 4 with hybernate mode 25 and the use of them combined).
    THE PROBLEM:
    Because of "Safe Sleep" even when RAM is still refreshed when mac enters Stanby ( from Sleep mode also called Stop in the GUI - more mess ) the contents of the ram are written to disk in /var/vm/sleepimage. So when a power faiure happens ( low batt, batt is removed, etc.) nothing is lost. In theory if you don't lose your power source you will always resume from RAM.
    Problem starts if you enable Power Nap / Darke wake. As you might have noticed when the mac wakes up every hour, every software was running is resumed ( not only apple specific tasks ). So you might find some trace in your syslog of programs not finding the net, for example.
    During this period of time the file system will be written by softwares and they internal state will be modified, so every hour the sleepimage file HAS TO be updated and rewritten not to create a dicrepancy between filesystem and memory after wake up from disk.
    by issuing this command, before closing my lid, I had the confirmation about that:
    Barfly-i7:~ syd$ while true; do sleep 120; stat /var/vm/sleepimage; date; done > AppleSleepIsMess.log
    that is the output:
    Barfly-i7:~ syd$ cat fuckSleepMess.log

    So it confirms that EVERY HOUR, after every wake up,  the content of your ram is written to disk!!! I will try also with AC connected later today.
    NOTE3: the stat output is: date of creation, modification, accesstime (no atime mount for me), attributes modification but the output format IS NOT written in the stat command manual making the man page useless. (we have another man ed here!)
    Thanks to the hilarious writer of the pmset manpage we know that Hybernate mode 3 is using bits 0 and 1 so without bits 2 and 3 set there should not be any page out for memory footprint before hynernating. My MBPr shoud write 16GB not 1.0 !
    Any comment, please?

    Hi,
    We are aware of this problem where the setting for "Battery Health Mode" does not work in the following case:
    1.  the setting is changed while the system is undocked
    2.  then, the system is docked.
    The dock battery will not know that the setting for "Battery Health Mode" has been changed.
    The work-around is to toggle the setting for "Battery Health Mode" while the system is docked, as you noted.

  • Can't locate Power Nap on Late 2011 Macbook air

    I've just upgraded to Moutain Lion and can't find the Power nap function anywhere. I have a new Air so I would expect to see it???
    Is anyone else having this problem?

    07/25/12 @ 11:59 PM - thread started
    07/25/12 @ 12:44 PM - determined your machine is supported
    07/25/12 @ 12:55 PM - determined a firmware update would be needed but that one does not currently appear to be available
    07/25/12 @ 12:58 PM - reiterated discovery made at 12:55 PM
    07/25/12 @ 1:54 PM - reiterated that you don't have the functionality available (4th time)
    I think it's safe to say that we've determined that a feature of OS X Mt. Lion (on supported machines) is not appearing to currently be available. So we can safely expect a future firmware update to be released that enables the functionality. A firmware update that currently does not appear to be available.

  • HT204032 Power NAP and Time Machine Backup

    One of the features of Power Nap is to allow backup even when the notebook is in a sleep .
    i notcied that even when Power Nap is enabled , i loose the backup process immediatly if PC goes to sleep. the condition happens when the backup is already working and after some time when not using the PC it goes to Sleep .
    is there a solution for the same ?

    Same here. Doesn't seem to work as advertised? Neither does it continue a backup when going into a "power nap"
    The info isn't clear, but TM has always cancelled a backup when going to sleep. 
    nor does it start a new backup during a "power nap".
    It should, but only if the previous one was more than an hour earlier.

  • Mountain Lion on iMac with no SSD - why is Power Nap forcing my computer to sleep?

    I have an iMac purchased in mid-2011.  It has no SSD.  So why is it going to sleep when tasks are still running?  If I'm encoding a video in HandBrake, downloading files in Firefox or Chrome, etc...the computer goes to sleep, despite the fact that it's still doing something.  Why is this?  If my iMac is not Power Nap capable, shouldn't it use the old method for determining whether or not to go to sleep?  Why can't we choose between Power Nap and previously functioning sleep behavior?

    Maybe this will help: http://forum.serviio.org/viewtopic.php?f=5&t=7791
    I am unclear on how that will help.  It is a link to a post from a user on a non-Apple website whose first and only post is about how this problem exists.  And I assume if you're referring to the Apple Discussion thread that other post links to, you would have just posted that link instead. 
    If you intended to link to that other Apple Discussion thread, from that discussion thread, Apple told one user, "Apps need to use power assertions while engaged on activities that should not be interrupted and we are working to evangelize this." meaning that Apple realizes they haven't done a good job of letting developers know of this; and that was from October 18, 2012, nearly 3 months after Mountain Lion's release date and I believe nearly 8 months after the first developer preview.  So by Apple's own admission they haven't done a good job regarding this issue.
    However, that does explain why Mountain Lion is behaving the way it did.  Both Apple and developers dropped the ball on this given that major apps (Firefox, Chrome, etc...) still don't implement Apple's new method of power saving.

  • How do I upgrade to 10.8 so I can use power nap?

    I want my Mac to update apps while it is in sleep mode and to do so I need "Power Nap" and I must have 10.8 firmware to obtain power nap. How do I get the 10.8 update on my Macbook Air 11inch mid 2011 with 10.7.5 already on it?

    You go to the app store and purchase a copy of it.

  • Power Nap Not Showing in Energy Settings of my 2012 MacBook Air

    I've updated to Mountain Lion, I have a new 2012 MacBook Air. Is anyone else able to see these settings? I can do a spotlight search for power nap, and it takes me to energy settings, but I get nothing else.

    im having the same issue as you zaze. my march 2012 macbook air hang every single time when it try to wake up from sleep mode. it started to happen after i upgrade to mountain lion and then the smc update. i believe is the smc update[power nap specifically] issue, because before that patch the Mountain Lion OS is doing fine[i update the smc patch a week after it was release so i'm pretty sure is tht smc patch issue.
    tire of playing around with the config, on this and off tht, it does not help at all and still hang[keyboard not responding , screen hang, sometimes cursur can move but it can do nothing with it].
    i need to go through this multiple times a day until i so fed up that i change sleep mode to kick in after it idle for 1 hour.

    Had a power outage and my iMac is on but the screen is black. How do I get it to light up again?

    Your system may have suffered hardware damage if not connected to a UPS  (Universal Power Supply), you can try doing a SMC reset, please click iMac SMC and PRAM reset for instructions. If that does not work make an appointment at your local Apple Store or AASP. BTW you can find UPS's at your local office supply store.

  • Does power nap work on the new iMac?

    i know it used to only work on new mac book pros. but what about the new iMac that comes with Fusion Drive?

    Welcome to the Apple Support Communities

  • HT204032 Will my MacBook Pro 13" (Late 2011) support Power Nap?

    As stated in subject.
    I read in some news that MacBooks with SSD (I have 500GB Apple Flash Storage) support Power Nap, but a firmware update didn't come for me.

    Since you have a Late 2011 model Lion will always be available to you from the Online Internet Recovery system. That is where the computer boots from across the internet from the Apple servers to an Online version of the Recovery HD, Mac OS X Utilities. Like this screen.
    From that you can do a Clean install of Lion after you erase the Macintosh HD partition.
    A Clean install is where you erase everything on the drive and reinstall OS X.
    If for some reason your original install of OS X on your original hard drive wasn't aligned properly and you used it to restore it to your SSD it can cause problems. Doing a clean fresh install will align the OS on the SSD.

    Everything is loading and working fine from the back up and I used the setup assistant system to load lion (because I dont have a disc it is on a portion of my hdd) I even got my outlook data to rebuild itself, but the computer just freezes after a while.
    On Friday before I bought this I talked with one of crucials sales rep and he said that they have something called garbage collector which does the same as trim and I dont need to do anything and it should work fine and it is basiclly the same thing just called garbage collector.
    As in firmware that I did not check but I just recieved it a day ago do you actually think that can be the case here?
