IMac won't wake from sleep

New iMac 27 purchased Feb 2014. If the computer is allowed to go to sleep, it won't wake up. Neither taping the keyboard or mouse has any effect. Pressing the power button whether momentarily or holding it for up to 30 seconds brings it back. The power cord must be unplugged for at least 15 seconds, plugged back in and the power button pressed to bring it back.
Setting the computer to never sleep seems to be the only thing that resolves the problem.
Allowing the display to sleep is OK.
Manually choosing sleep from the Apple logo is OK.
Base model iMac 27 with just one option, the Apple 256GB SSD
Performed all the updates after first turning on the machine yesterday
Two external WD 4TB USB3 hard drives, one for data and the other for TimeMachine
Canon Printer
Canon Scanner
OSX 10.9.1
Any ideas?
Thanks,

IMac won't wake from sleep since Lion!

Since installing Lion my iMac (intel core 2Duo) won't wake from sleep properly using my wireless keyboard, trackpad or magic mouse! I haven't changed any settings and I have to hold down the power button to force shut down and then restart! Any help?? x

Hi all
Finally went to the Genius Bar to ask the question as nothing has worked. They said I needed to reset my PRAM. I did it (Following these instructions... http://support.apple.com/kb/ht1379 ) and it worked.
So relieved....it was really annoying me.
Hope this helps others with the same issue.
Thanks

HT1338 Imac won't wake from sleep when a facetime call comes in

My Imac will not awake from sleep when a FaceTime call comes in.

I've had this problem several times now, and I do no own MobileMe. I don't use any bluetooth peripherals, but I've noticed that the precursor to the problem is that my bluetooth icon in the menubar goes from normal to "Bluetooth Unavailable." Then at some point later on, I put the iMac to sleep and it won't wake up.
I've read elsewhere that the bluetooth unavailable problem may be connected to the power management unit, which may in turn explain what is going on with it not rebooting. But I'm not sure.

TS3824 My iMac won't wake from sleep after installing the most recent OS update.

I'm having trouble with my iMac, the screen won't wake up after it goes to sleep. The one time it did the screen was all fuzzy and pink. This has only happened in the last few hours after installing the latest OS X Lion update. Is this normal? Can someone help?

Hello, not normal.
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
/private/var/run/StartupItems
/Library/StartupItems
/System/Library/StartupItems
/System/Library/LaunchDaemons
/Library/LaunchDaemons
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partitiion & use Disk Utility from there to Repair the Disk, then Permissions.
Re-install if that doesn't work.

10.8.5 iMac Won't wake from sleep/screen saver with require password set

I have several iMacs 2009/2010/2011 that are set to require a password when waking from sleep just this week all of them started freezing when this happened and will not start back up if restarted - they go pasgt the Apple Logo w Spinning gear to the Apple Log & Mouse icon - but don't make it to the login screen
The only way to get past it is to safe boot and delete the loginwindow.plists and loginitem.plists - and in one case go in in target mode and delete it
They are all up to date - the last updates I did were the 10.8.5 Supplemental Last week - and ARD Client 3.7.1 - Monday.
None of them have done again this since I deleted the plists
Has anyone else run into this? If so does anyone know if it is related to the updates or do I need to keep digging?
Thanks
Robbie G

I am having this problem still, even after updating with the latest combo. I find that my Macbook Pro (using 10.8.5) will show the beach ball spinning with a black screen. I have to restart the laptop in order to clear this problem. Very annoying since this can happen two or three times a day.
You mention 'plists'. What are they? And if you delete them, are they recreated automatically upon restart?

IMac won't wake from sleep mode after latest update

Hello, I have a Late 2013 27-inch iMac that has started acting strange, lately. After installing update 10.10.3, my iMac almost will regularly not wake once it enters sleep mode, after being idle for a certain period of time.
Is anyone else having this problem, and/or have any solutions for this?
Thank you in advance!

Step 1
Take all the applicable steps in this support article. That's the starting point for any further efforts to solve the problem. Please read the whole article carefully and don't skip any of the steps, including the ones under the heading Additional troubleshooting. If you don't understand any of the steps, ask for guidance.
Also note that if you replaced the internal hard drive with an SSD, or if you're starting up from an external SSD, then that device may be causing the problem. Check the SSD manufacturer's website for a firmware update. The only solution may be to reinstall the original drive or avoid sleep altogether.
Step 2
If you're running OS X 10.8.5 or earlier, from the menu bar select
           ▹ System Preferences... ▹ Accessibility
If the checkbox at the bottom marked
          Enable access for assistive devices
is checked, uncheck it and test.
If you're running OS X 10.9 or later, select
           ▹ System Preferences... ▹ Security & Privacy ▹ Privacy ▹ Accessibility
If any applications are listed on the right and have a checked box next to them, uncheck all the boxes and test. You may first have to click the padlock icon in the lower left corner of the window and authenticate as an administrator to unlock the settings.
Step 3
In the Energy Saver pane of System Preferences, uncheck the box marked
          Put hard disks to sleep when possible
Step 4
If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later.
Step 5
This and the next step must be taken as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad and start typing the name.
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ Diagnostic and Usage Messages
In the search box in the window's toolbar, enter "powerd" (without the quotes.)
You may see one or more lines like this:
com.apple.message.signature: Platform Failure
If you do see that, and you did everything in the preceeding steps, then you're dealing with an internal hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
Step 6
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that heading, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down.
You may see one or more reports with a name that begins with "Sleep Wake Failure" followed by a date. Select the most recent one. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
I know the report is long, maybe several hundred lines. Please post all of it anyway.

IMac won't wake from sleep mode

Just wanted to share my experience in case anyone has this issue.
Computer would only start after sleep mode if I unplugged the power cord. The power button would not do anything, even if I held it for a long time.
Shut down and start up would work normally. Only effected sleep mode.
After much trouble shooting I found that I had a bad USB hub. Everything on the bad USB hub would work fine so I didn't suspect it.

Very interesting, thanks for sharing.

IMac won't boot if Firewire device is turned on/won't wake from sleep

I am sometimes having an issue where my iMac won't wake from sleep; after I restart the iMac wont reboot (grey screen) until I power off the LaCie 300GB Firewire drive. I just bought this iMac a couple of weeks ago but the Lacie was on a PPC G5 Tower before and always was OK. I have no other Firewire devices to test the port with so my resources are limited. Anyone heard of anything like this ?

I noticed there is a firmware updater for LaCie drives. I don't know if it applies to your product, but here it is

Hi 02SilverSport,
Try using the power button to wake the iMac.
OS X Mavericks: Using the power button
http://support.apple.com/kb/HT5869
If you are using a wireless keyboard or mouse, check out this article:
OS X Mavericks: Wake your computer with a wireless mouse or keyboard
http://support.apple.com/kb/PH13997
And for more generic troubleshooting, try this one:

where there's a section for "Your computer cannot wake from sleep" and "Your computer is slow to wake from sleep".

IMac 17inch G5 won't wake from sleep

Hi, my iMac G5 1.8ghz won't wake from sleep. It had been running poorly for a couple of weeks so I've re-installed Leopard however the underlining problem has not been fixed, which leads me to think it may be hardware? If i leave the iMac alone it enters into sleep mode successfully however nothing will wake it. I've tapped every key on the keyboard and nothing works. I then have to hold the power button in and re-start it. The only alternative I've found so far is to turn off sleep in system preferences.
Thanks for any help

Have you reset the SMU and the PRAM? Try deleting the System Preferences .plist in User>Library>Preferences>com.apple.systempreferences.plist. Please post back with results,

IMac 6 won't wake from sleep

This is a 2nd hand question, as the computer does not belong to me, but I'm trying to assist a friend.
The iMac will not wake from sleep. If the hard drive is set to never sleep, the system will come out of sleep. But if the hard drive spins down and the system goes into standby mode, it can't be awakened. Not by a short press of the power button, movement of the mouse, or click of the keyboard (wired or wireless).
The iMac was taken to an Apple store for diagnosis. They used a 3rd party software tool (not the default OSX diagnostics) that showed no hardware issues per se, but it was noted that when putting the iMac to sleep and attempting to awaken it, the processor never gets a signal to do so. They surmised that it may be a power supply issue or something to do with a component on the motherboard. They re-installed the OSX completely fresh to rule out software as an issue. But the next day, the owner found that the same problem persisted.
First, I'm curious to know if anyone has ever reported this problem with the iMac 6 and if there's a known culprit. And naturally, if that culprit is easily fixed or if the motherboard would have to be replaced.
Second, since the problem does not happen with the hard drive staying "awake", would this problem be averted by installing an SSD?

Hello, what 3rd party Apps might be installed?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.

IMac won't wake after sleep

Hi
I have a brand new iMac 21.5" with Hybrid drive.
Its OS and apps are fully update to date.
Strange thing is that it won't wake from sleep.
To reboot, I have to turn the power off at the wall and back on again. Neither of the usual
wake/reboot processes work (holding the power button briefly or holding the power button for
> 10 seconds). No combination of opt/ctrl/cmd/power work either. I have to turn it off at the wall
and back on again, after which it immediately boots.
I've reset the SMC and NVRAM/PRAM.
I've checked the power options - which are set to defaults (sleep after 15 IIRC).
I've also checked the console log at the time of sleep - and there is no indication of anything
going wrong (an example is below).
Does anyone have any other ideas as to what I can try before going through the painful process
of sending it into the shop?
Many thanks.
Paul.
Console log below. You can see the machine went to sleep after 12:05pm, and I woke it up and 8:20pm. There seem to be no unusual messages in the middle.

I have gone to the apple support team - and they took me to the standard apple "what happens if your mac won't turn on" page
(If your Mac won't turn on - Apple Support) and walked me through the standard checks (which I'd already done).
The support guy thought it was a bad driver - I'm not so sure as I haven't installed anything new (just updates).
Anyway - I was just hoping/wondering someone in the wider community had seen this issue before I take the machine
in for servicing.

Won't Wake From Sleep

I held off from posting this until I'd scoured the boards looking for ideas, but I'm totally out.
Every since I updated to 10.4.8, my MacBook Pro won't wake from sleep. I've tried resetting the SMU and PRAM, enabled and disabled bluetooth device wake from sleep, and installed the latest EFI Firmware update that was just released. I've now narrowed it down to the 10.4.8 and a change in how it handles Expresscards. If I have my NitroAV FW 800 card plugged in during a session, it seems to prevent the MacBook from going to sleep properly. According to various Console messages, the PCI device prevents the computer from going to sleep, and /or places the computer into System Doze instead, from which it won't wake. The sleep light stays fixed and steady, only disappearing if I press the power button (it only reacts to the power button). From there the screen remains dark and all plugged in device fail to respond. I can hear the drive spin back up.
It reacts the same whether or not I eject the card before putting the computer to sleep. This behavior was not present before installing 10.4.8 and having fallen back on a back up of my 10.4.7 install, can say it's not present in the older OS version. I was hoping last night's EFI firmware update would deal with this, but after having installed it and 10.4.8 anew, I'm having the same old results.
If anyone has any new ideas or can direct me toward how I can make sure the folks at Apple see this, I'd greatly appreciate it.
MacBook Pro 2.16 Ghz Core Duo Mac OS X (10.4.8) 2 GB Ram, 7200 rpm HD, NitroAV ExpressCard FW 800

Macbook Pro with Leopard Won't Wake from Sleep

I'm intermittently, but with increased frequency finding my MBP won't wake from sleep. A copy of my log is below. I've snipped out where the log repeats. A common message is the "unknown SIGSEGV code 0". Any ideas what the issue is? How can I go about diagnosing?

Hi David,
- Have you tried any troubleshooting steps?
You may try the following steps:
1. Reset SMC as per the following article http://support.apple.com/kb/HT3964?viewlocale=en_US. If this does not resolve the issue then go to step 2.
2. Navigate to Macintosh HD/Library/Preferences/System Configuration and remove a file called powermanagement.plist (drag it to trash, might prompt for a password). Restart the mac thereafter. If this does not resolve the issue, boot to safe mode as per http://support.apple.com/kb/ht1455 and check the issue there. If it works there, you will have to remove the following files to check Macintosh HD/Library/StartupItems, HD/Library/Caches and then restart the mac.
Let me know if this works.

OSX 8.2 new Retina Macbook Pro won't wake from sleep.

Since upgrade to OSX 8.2 new Retina Macbook Pro won't wake from sleep. Tablet lights are on in morning and fans running like crazy, but it requires hard quit and start. Tried with no apps running, no change. It was fine before this last update. Wasn't the recent firmware update supposed to fix this issue? It seems to have started one for me.

I have the exact same problem with my Macbook Pro OS 10.8.4. What happens is: I work on the train, press cmd/alt + eject to put to sleep..pop it in my bag...get home or office... open the lid...and nothing! Battery indicator shows I have plenty of juice but it will not wake up no matter what key I press.
The only difference between use on the train and home/office is the plugging in of peripherals and mains power. It happens sparadicially, perhaps once or twice a week and I always send a 'panic report', so somewhere there will be approx 20 reports of this fault at Apple.
