Hello all,

I have a very annoying problem in that my iMac takes ages to go to sleep. It used to be instant but it now takes ages. I've no printer and I have reset pram and smc but all to no avail.

Does anyone have any ideas?

    Some users put their computer to sleep, while others shut it down. Some users aren't aware of the difference, but it's a really important difference.

     

    I'll take you at your word. You probably sleep your iMac by pressing Cmd-Option-Eject at the same time; your machine should sleep in one or two seconds, and wake up just as quickly.

     

    If, however, you shut down your computer every time, it will take longer to shut down; the time varies by the size of your HD and the amount of RAM that's installed. Usually, between five and twenty seconds. If your RAM is maxxed out, or you don't have much HD space left, that could be the explanation.

    Hi, Thanks for your reply,

    I put it to sleep from the apple menu and via the shortcut keys. It wakes instantly its just the sleep that seems to be the issue.

    I've got 16gb Ram and 976.79 GB free on my 1tb Hdd.

    I'm at a total loss. I've read elswhere that it could be a print que problem, but I've no printer installed.

  • Poikkeus Level 4 Level 4 (2,785 points)

    Ah, 16GB RAM - that could be the source of the problem.

     

    Adding RAM is a great idea, especially with RAM-hungry applications, but it can really slow down sleep. Read this thread on commands to reclaim the sleep image:

    http://forums.macrumors.com/showthread.php?t=1416347

     

    Or, you could insert your old 8gb RAM module (if you still have it), and see if that improves things.

     

    Post with your results!

    Sound like either a running process or sharing preference.

    Thanks, tried all those ideas but no joy.

     

    I've run this in the terminal 'pmset -g log' :

    Not sure if this shows anything.

     

    My hibernate mode was set at '0' so I didn't have a sleep image. I set it to '3' to create one, but no luck with that.

    I'm not sure exactly which Sharing Service or Apple Device is using "ApplePushServiceTask" because for privacy all my Sharing Services are off unless one is needed.

     

    Go to Apple > System Preferences > Sharing and try turning off your Sharing Services one at a time, then test the iMac to see which one is preventing it from sleeping.

     

    If you find that you need that Sharing Service on for whatever reason(s), then only the Display and not the iMac can sleep.

  • jaggedpixel Level 1 Level 1 (0 points)

    All sharing is off

  • jaggedpixel Level 1 Level 1 (0 points)

    I'm thinking I may do a total reinstall to see if that sorts it out.

  • den.thed Level 7 Level 7 (24,695 points)

    OK next try ejecting and disconnecting your Seagate Storage Drive.

     

    It might also help us to know if you are using the Seagate for TM Backups, Media storage and playback or using Seagates Backup?

     

    For example: Are your iTunes Libraries stored on the drive and if so, is iTunes open and using the Library? If so, then try quitting iTunes and see if that will allow the computer to sleep. This may also be the case with other open App's like iPhoto, if your Libraries are stored and in use on the external drive.

  • jaggedpixel Level 1 Level 1 (0 points)

    I use the Seagate Goflex for both TM and the Libraries. I've tried it diconnected but still that same issue. My internal is also a seagate.

  • den.thed Level 7 Level 7 (24,695 points)

    OK next try changing the batteries in your Apple wireless devices and then start removing other USB devices one at a time and see if it will sleep.

     

    Sorry I'm not good at reading the Logs and after re-reviewing them, I now see a "Wake due to EHC2/HID Activity: Using AC"

     

    On that note, see > Something keeps waking up my Mac, how do I find out what it is?

  • jaggedpixel Level 1 Level 1 (0 points)

    OK Tried that and still no go. Totally at a loss with it.

  • den.thed Level 7 Level 7 (24,695 points)

    Me too..

     

    Through all of this, have you tried...?

     

    Resetting the SMC > Resetting the System Management Controller

     

    1. Shut down the computer.

    2. Unplug the computer's power cord.

    3. Wait fifteen seconds.

    4. Attach the computer's power cord.

    5. Wait five seconds, then press the power button to turn on the computer.

     

    and then the NVRAM / PRAM > About NVRAM and PRAM

     

    1. Shut down the computer.

    2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.

    3. Turn on the computer.

    4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

    5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.

    6. Release the keys.
