Won't sleep, won't start up.

I've had two problems today. My iMac was shut down last night and this morning it would not start up for me at all. After 3 attempts at starting from the power button with no luck I eventually had to unplug it from the wall. That worked but once the start-up was complete I had the message that "Mac OSX had unexpectedly quit". I was hoping this was the end of the problem.
I did the software update today and then repair permissions.
That's when my computer decided it would not go into sleep mode at all. I eventually did a restart to see if that would fix the problem. The same message appeared "Mac OS X had unexpectedly quit".
Does anyone know what's going on here ? This iMac is only 6 weeks old.
14 iBook G4 768MB; 20G iPod   Mac OS X (10.3.9)  
20" Intel iMac, 20G iPod , iPod shuffle   Mac OS X (10.4.9)  

The two things I would try are;
1. Reset the NVRAM, and.
2. reset the SMC.

  • Won't sleep, won't wake

    I'm having two problems with sleep mode:
    WON'T SLEEP
    my iMac G5 won't sleep even though sleep mode is activated in Energy Save preference pane (file sharing off).
    WON'T WAKE
    When I put my machine to sleep at night (sleep item under apple menu), it won't wake up in the morning. The blinking sleep light indicates my iMac is in sleep mode. I hit a key to wake it. The sleep light turns off. Nothing else: no noise, no screen but the black on. I wait a few minutes and press the power button: nothing happens. Once it starts up after a hard boot (power button, 5 secons). Most of the time I have to wait an hour or two and then I can start up my machine by pushing the power button.
    This problem occured yesterday for the first time. Today I did many test with same results: no wake after "manual" sleep mode and no "automatic" sleep.
    Note: Apple Hardware Test did not detected any problem.

    Even though the hardware test did not indicate a problem, you may still have one. I'd give AppleCare a call. Also note, if you are out of the one year or AppleCare coverage, you may still qualify for this program:

  • Applications freezing, won't sleep, won't shutdown

    I've only had minor problems with Leopard, but have become quite concerned of late. 
    Over the past few weeks, Skype (older version 2.x??) would suddenly freeze with the beach ball, and nothing would make it shut down.  I would try force quit without success.  Went into activity monitor, but it wasn't even being shown there.  It was, however, still showing as being open on the dock. 
    I have to use skype everyday at work, so sometimes I would continue plugging away on the internet, then Safari would start to freeze and I'd have the same problems with quitting Safari. I'd manually force a reboot by holding down the power button, and usually i'd be sorted out. 
    I'd be fine and then a few weeks later this mysterious behaviour would reappear.  I downloaded 10.5.8, then Safari 5.0.6, and decided to get the new version of skype 5.2
    Things seemed fine until today when these same symptoms reappeared.  This time, however, they seem worse. 
    1. skype would sometimes merely bob up and down when i tried to open it.  when it did open, it would freeze upon receiving a message
    2. safari would then (sometimes) follow suit.  freezing up.  sometimes it didn't (i rebooted using power button numerous times today)
    3. i tried to open itunes and it would bob up and down without opening.  on another occasion it did open, but when i tried to play a song it froze.
    4. when things *seemed* to be running smoothly, the fan would be whirring away...even though I only had MS Word open.
    5. Again force quit would do nothing.  Skype would never show up in activity monitor, despite showing on dock as still being open.  itunes, however would show up in activity monitor and i coudl quit. 
    6. other applications (i checked for new software, for example) would randomly freeze adn general operations were sluggish.
    7.  After a cold reboot, I tried to logout again without having opened any applications and it would merely hang and not logout/restart/shutdown.  I went into activity monitor again to kill login to see if that woudl work, but again it would just hang.
    8.  when it appeared to be running normally (minus the whirring fan), i closed the lid to put the computer to sleep, but it did not sleep. 
    Those are the symptoms.  I've tried:
    -repairing permissions
    -trashing skype
    -clearing cache (system/kernel)
    using onyx for various other cleanups
    but the problem persisted. 
    Verifying disk said all was ok.  unfortunately, I do NOT have my original disks with me.  I am currently overseas (to where I would normally call home and foolishly did not bring).
    I hadn't tinkered with anything nor downloaded anything odd.
    running 10.5.8 on MacBook.  2.2GHz  2GB memory have over 10% of free disk space available. 
    if anyone has any ideas, would appreciate it. 
    A big clue, perhaps....I decided to log into my Admin account, and safari is acting fine, adn the fan is not going crazy.  not sure about skype, as i keep this account pretty bare, but shall try downloading later and report back.  Will also post a log of when itunes froze
    Thank you ! 

    i've returned home now and everything seems to be fine again.  strange!
    I read a different thread in which someone described a problem of applications not shutting down, and thinking it had to do with his wireless connection. 
    that sounds too bizzarre to be true, but that's the only thing that's changed from when i was at work until now at home. 

  • Mission Control won't work after sleeping.  Upon Start up it's fine, but after sleeping it won't work by track pad or keyboard.

    Since updating, Mission Control won't work after sleeping.  Upon Start up it's fine, but after sleeping it won't work by trackpad or keyboard. I'm sure I use Mission Control more than most, so it's really irritating for me.

    No, the versions of iPhoto on the iPad and on OS X are totally different.
    What Apple ID are you using for the Mac App Store? Who else has access to that Apple ID, or what possible other Apple IDs could be in use? It's possible you'll need to purchase iPhoto to get the upgrade, though I'd think Software Update should offer you the correct version.

  • Macbook Pro won't sleep after updating to 10.4.11

    Hi,
    I just updated to 10.4.11 reluctantly from 10.4.9 as whenever I do update I always have issues...I basically just went to software update last week and updated to everything I could. I've just been reading the forums and noted that updating is not always that easy...
    Well basically my computer won't sleep if the lid is left open, this is IMMENSELY annoying since I often leave my desk to work on drawings, and I don't want energy being wasted like it is at the minute. Call me picky but I just want my computer to work.
    I've reseted the PRAM, (option, alt, p and r), closed all applications, etc, but no luck...
    Its a 2.2ghz MacBook pro, 2GB. Thank you in advance
    Neal

    The important thing for the future imho, is to always Repair Permissions before & after any update... seems to ward off most of these problems. Of course that is only good if the disk is Verified once in awhile.
    Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks...
    http://docs.info.apple.com/article.html?artnum=302672
    About Disk Utility's Repair Disk Permissions feature...
    http://docs.info.apple.com/article.html?artnum=25751
    In fact I'd start with those 2 now, if that doesn't help you may need to reapply some updates by getting them directly from apple>downloads.

  • Machine won't sleep on it's own.

    This may not be a Leopard specific issue, I had it with Tiger also. My eMac and new iMac won't sleep with the HP All-in-One printer software installed. The software has three active apps (one which controls a root process) that won't let it sleep. I can manually sleep it, but the energy saver setting is useless. The display will sleep, but not the machine.
    I posted in the eMac category, but this is not machine specific, either, seems to be HP specific.
    I trashed the culprit apps, but then I couldn't scan (the device was not found); it did let the machine sleep, though. I tried fixing the permissions after re-installing the latest software from the HP site (a VERY long process), and turning off the printer, still no sleep.
    Anyone else have this issue? Any suggestions? I thought maybe if I created an alias for the culprit apps and stored the originals on a removable device, or even a .dmg and only mount it when I need certain printer functions, that may stop them from constantly running.
    Any help would be appreciated
    Bob

    Thanks gws,
    My eMac FINALLY achieved sleep last night after about 50 min. I have the sleep timer set for 1 minute, maybe the fact there was a scheduled TM backup kept it awake. I have the printer turned off, and it has been manually slept and re-started since it was turned off, don't know if any of those was a factor.

    I had anacron installed, but removed it the best I could, it is not needed in Leopard.........
    Thanks for the advice, gws, maybe your system would react the same after re-start and/or sleep with printer turned off?
    Bob
    P.S. Be sure your Mail is not set to check for new mail every 1 minute, that will stop sleep, too

  • My MBP won't sleep HD, and I have tried every solution already posted.

    This is a persistent problem that began over 1 year ago, so information about how this unit might have been configured when it began is no longer available, but I have scoured this and google in general, using all search terms I can think of and still I can not pin point a reason my HD will not sleep.  I have been advised that there is a "process" keeping my unit awake, but I don't understand how that is possible when it won't even sleep when it is on the startup screen. So here are some particulars.....maybe you have some new thoughts?
    I drive a MBP with a 2.4 Core Duo processor running OS 10.9.1, 5gb of mem, 750gb of storage with 500+ free.
    1) I made a clean install of system software and a clean upgrade to Mavericks (as a way to try to solve the problem which began when I was using Mtn Lion).  There is no third part software loaded onto the machine, yet.
    2) I have yet to launch iTunes, or iPhoto, or a Browser, no printer has been added.
    3) The result is the same regardless of user or preferences.  It does it in "safe mode".  The Terminal doesn't give any reason for aborting sleep using "pmset -g" command.  It just has a "10".  Bluetooth is turned off, notifications are turned off, sharing is turned off, airport is turned off...it's not even connected to the internet. The only software on the computer is the system. There are no peripherals.
    4) It won't sleep even on the start-up screen.  It won't sleep if I go through the menu or close the lid.  It will power off the monitor, and begin to wind down the HD, but just as it reaches the end of the sequence BING and the screen comes on again.  If the lid is closed, it will stay that way until the battery runs out, unless it's plugged in.  SMC and VMRAM resets not effective.
    5)  I have no files on this computer so I don't care about losing them.
    6) This computer did not have this problem using Snow Leopard, and even worked for a time using Mtn Lion and changing to Mavericks has not affected the problem which leads me to think it's not OS related.  It acts like a firmware issue, but as far as I can find there is no firmware upgrade for my unit.

    Hello Bobz,
    Thank you for responding.  You require that I modify #2, above.  I have now gone on internet, opened Safari.  I downloaded etrecheck, restarted, waited for computer to cycle through sleep cycle (1 min).  After failure, I ran etrecheck.  Here are the results:

  • Macbook Pro won't sleep properly.

    Hello;
    I have a problem with my mid 2009 13'' MacBook Pro that won't sleep properly.
    Whenever I close the lid, or chose ->Sleep, it takes a few seconds and the system sleeps (fan off, led fading off) , but INMEDIATELY after just a few miliseconds, the system wakes up again (fan on, led on, hdd spinning).
    This sequence happens again and again indefinitely (sleeps / wake / sleeps / wake, and so on...)
    Then I open the lid and everything works as expected.
    So far I tried all this, with no luck:
    - I've installed a clean Mountain Lion from scratch.
    - The system is untoched: no new apps installed, no new drivers installed.
    - All sharings are disabled.
    - Bluetooth is disabled.
    - Infrared port is disabled.
    - There's nothing attached to the computer except from the magsafe cable.
    - There are no background processes preventing the system from sleep  (checked  using "pmset -g assertions")
    - There is no disc loaded in the optical unit.
    - "Wake for network access" is disabled in Preferences->Energy Saver.
    - SMC y PRAM reseted several times.
    As you can see, I don't know what else to try...
    I would REALLY appreciate any help or suggerence.
    Thanks in advance,
    Nicolas.

    A SMC will not have any results with this, in my past experince. Surprisingly the loginin items is the usual culprit.  Try option, command, delete (don't hold these keys ,just press them)and wait till it goes to sleep, and stays that way. Then if it stays aslep try closing the lid. Disconnect all peropherals. Try system preferences>energy saver, make sure comouter sleep is ot set to never, as well as the display on both power adapter and battery. On the same pane, click schedule and make sure the start up or wake is not clicked.  Also try a Ssfe boot: Power off, power back on holding the shift key, coninue to hold the shift key till you see the progress bar.This will disable all 3rd party software (it some times fixes some stufff) try the sleep menu under the Apple, or the option,command,delete.  Hope this offers some help.  If yourMBP is new, less thsn 1 year old, or you have Applecare, I would let them deal with it. You have a warranty,USE IT!  All the best
    Close all applications/operations.
    You ca try a pram reset for the heck of it, in case there is somrthing strange in there that needs to be flushed.
    Pram reset: Power off, power on, hold the following keys before the start chime. option,comman,P,R (no commas) and continue to hold the keys till you hear thestart chime 2 times then relesase.Reboot.
    Good luck

  • Pro won't sleep automatically

    Bought a new pro and used migration assistant to move stuff from my iMac.
    Now the Pro won't sleep automatically. It sleeps when I tell it to or on Schedule at 0100 but not after x mins of inactivity.
    The iMac it migrated from had no such issues.
    Is there any reset I can do to cure the problem?

    I have about a 2 year Mac pro (intel) and it will not sleep on its own. I can manually sleep it.
    The hard drive cycles up and down about every 2 minutes or so continually and the display remains blank. It will keep cycling the drive until I manually sleep it.
    I tried a few times doing the reset thing and once it helped but in a week or so it started to do it again. I went and made up a new user and it seemed to fix it for a month and then it want back to doing it again. It is very annoying. I even updated it to Leopard and it sill did it. I'll try the reset again and see.

  • MacBook Pro Won't sleep sometimes

    Soon after starting my MacBook Pro (2010 model) it will be able to sleep. However, after some time, it will being able to sleep. It won't sleep when I close the lid, or when I choose sleep out of the Apple menu. I've tried quitting all applications, the system won't wake from incoming network connections, and I haven't changed anything more than getting a new external hard drive recently.
    I've also tried checking the console for issues, but couldn't really find anything (although I'm not certain what I'm looking for) and resetting the pram. I'm pretty certain the problem is somehow software related, but I'm not sure.

    Try a SMC reset. It governs such things.

  • MacBook Pro won't sleep or shutdown (intermittent problem)

    Every so often my MacBook Pro won't sleep or shut down. I can't find any rhyme or reason to it.
    I notice the problem when I close lid, and it doesn't go to sleep. I then hit apple menu:sleep, and it does nothing. I hit shutdown, and OS shuts down, but gets stuck at blue screen with spinning circle indefinitely. Have to hold power button for 5 seconds to finally shut down. Startup is then slow, but doesn't give me an error message indicating improper shutdown or failure.
    Most of the time it sleeps fine and shuts down fine.
    Other posts seemed to have the problem more reliably, and the fix had to do with startup items. Mine is intermittent, and the only items in my startup folder are Norton Antivirus and Parallels.

    I am also experiencing the exact same problem you are describing. Completely random when the machine will not sleep or shutdown, although it seems to occur more often when I've had the machine running for a few days, moving between home and office locations.
    I have VMWare Fusion and Office 2004 installed. No iStatPro. I'm wondering could it be related to the kernel extensions that VMWare and Parallels install? Is anybody experiencing the non-shutting-down problem who doesn't have either VMWare or Parallels installed?
    I found the following section in my system.log file that occurred the last time the machine wouldn't shut down. May be of some use to somebody

    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
    Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
    Step 6
    Boot in safe mode and log in. The instructions provided by Apple are as follows:
    Be sure your Mac is shut down.
    Press the power button.
    Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
    Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Note: If FileVault is enabled under Mac OS X 10.7 or later, you can’t boot in safe mode.
    Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the Mac OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
    If sleep now works as expected, go on to the next step.
    Step 7
    Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
    Step 8
    If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
    If you still have the sleep issue after booting out of safe mode, post again.

  • Ibook insomnia (it won't sleep)

    I just recently installed Tiger and now my ibook won't sleep when I request it through apple menu. It will sleep for about 15 seconds and then wakes up on its own. I have checked my energy saver settings and they are set at 10min.
    Additionally, when I close the lid it does the same thing sleeping for approx 15seconds and then wakes up. Any suggestions?

    i was reading "Troubleshooting Mac OSX Tiger" and it suggested for sleep issues to check the console log and I did so I put my ibook to sleep with the console log open then once it woke up (after a few milliseconds) this is what came up in the log:

  • PowerPC won't sleep

    For the last couple of months, my PowerMac won't go into sleep mode after the set amount of time has passed. I can sleep it manually, but if I walk away it will run all day, although the screen will turn off as programmed.
    This is a G5 dual 2 ghz machine fro around 2005, running OS X 10.5.8. I've noticed that my wife's similar vintage iMac won't sleep automatically anymore, either, leading me to believe that this might be an OS issue.
    Thanks for any suggestions,
    Ian

    Hi Ian, this has cured it 2 or 3 times, at least a good start.
    I think you should get Applejack...
    http://www.macupdate.com/info.php/id/15667/applejack
    After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
    applejack AUTO
    Then let it do all 5 of it's things.
    At least it'll eliminate some questions if it doesn't fix it.
    The 6 things it does are...
    Correct any Disk problems.
    Repair Permissions.
    Clear out Cache Files.
    Repair/check several plist files.
    Dump the VM files for a fresh start.
    Trash old Log files.
    First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files!
    Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

  • Late 2011 Macbook Pro won't sleep!

    So I purchased a late 2011 macbook pro brand new from an apple store 3 weeks ago. Everything seemed well at first (except for a wake issue I had... odd)
    Anyways... I started noticing that my notebook wasnt going to sleep, so I adjusted the power settings to sleep after 1 minute...
    Sometimes the laptop will sleep after 20 minutes or more... sometimes it won't sleep at all (on all night!)
    I'm wondering what the heck is going on? I tried re-installing Lion and using migration assistant to bring all my files back... no dice. same symptom.
    -I've re-installed Lion
    -I've tried SMC and PRAM resets
    -I've tried "pmset -g assertions" and see no conflicts
    -I've tried "pmset -g" and see nothing odd
    -I've tried clicking / unclicking all the "sharing" settings
    -I've made sure ALL applications are closed
    -pmset -g log returns a few "slowresponses" but nothing too crazy (200ms)
    -system log returns some odd "wake for GIGE (network)" responses while im trying to make it sleep.
    -I deleted all printers /ques
    The system WILL sleep if i manually click "sleep" or use the power button.
    The system WILL sleep if i unplug the power cable and close the lid.
    I have a 2nd display using a thunderbolt to DVI adapter... but unplugging this seems to have no effect.
    What am I missing? could this be a logic board issue on a brand new mac? I'm lost! any suggestsion would help!

    I may have solved this -- maybe -- by reinstalling Mavericks.  Two days after the re-install (which was easy), the sleep function seems to be working properly.
