IMac :: Waking From Sleep Or Restarting After Shut Down
Nov 15, 2009
My 24in iMac is waking from sleep after about 5 seconds every time, as well as restarting itself after I shut down. This problem started early yesterday evening, and so I did the usual: resetting the SMC/PRAM/NVRAM with no luck. I checked console for messages and found lots of references to imagneto_user_agent (I'd installed iMagneto shortly before and then deleted it as it didn't seem to be working properly). With some help from another user I managed to delete all the hidden/locked folders and files connected with this app using a combination of Trash It and fiddling in Terminal.

so i've been having an issue with the double tap to hi-light any text i wish to copy. Such things as double tapping the URL bar to hi-light the whole url so i can just retype w/e site i want to go to. Every time i restart or turn off or my mbp goes to sleep and i reopen it, the double tap function resets. So i'm forced to go to the system preferences > trackpad> "double-click speed" to slowest in order to get my double tap to hi-light anything again. Is there something wrong with my mbp? Or is there a way i can save the settings when i put the double-click speed to slow so that it wont reset every time my mbp needs to be woken up or restarted?

Has anyone had this problem?
I have a (reletively) new iMac purchased in Nov. 27" 3.06 Ghz 4 GB Ram. The machine sleeps on it's own overnight from non use and then when i get up in the morning I click the mouse and I hear the machine waking up, (harddirve, cd-rom, etc.) but the screen stays blank. This happens in OSX and Win7 doen't matter what OS is running so it appears to be a hardware issue. Maybe there is a firm ware update, or somthing. To use the machine at that point, my only option is to force the machine to shutdown and then reboot. If I reboot to fast, meaning if I don't wait about 5-10 seconds after the shutdown, then the machine proceeds to boot but without any visuals, the screen stays blank.
Should I just take the system back to the apple store? Will they grab the current image and put it on a new machine...

I almost always put my iMac to sleep every night. Ever since about a week ago it started waking up, and waking me up, in the middle of the night. And yes in that week I have tried shutting down and it still does it the next day.
I don't have any apps open that I don't normally, didn't change any settings i'm pretty sure.
I tried the list from apple that lists reasons it would wake unexpectedly and googled but nothing works.

After I put my iMac to sleep it keeps waking up by itself. What would be causing this? (OS 10.5.8 Leopard)

Newbie here, It has just come to my attention that my 27" iMac wakes up during the night. It is always put to sleep at night rather than turned off. My parents are staying for the weekend & sleeping in the same room as the imac, & mentioned this morning that screen turned on a couple of times during the night. I looked at the time machine back ups & found it had made 2 during the night.

So I have my iMac running W7 64 and whenever I put it to sleep, it sometimes wakes up from it. I have a wireless mouse which I switch it off and still it wakes up.

The AirPort on my new iMac 21.5'' 4670 is having problems these past couple of days. Every time I put the machine to Sleep and wake it up again, the AirPort cannot find any network. My wireless is fine and there are other wireless networks the machine can detect when it functions well. I have to restart the computer to have the AirPort work properly again. I thought it was a temporary issue, but after repeating a couple of times, it seems to be very easily recreated. And sometimes the AirPort does not function even from a restart. I have to restart another time to have it work.
Does anybody else have the similar problem? I hope it's just a software problem that will be addressed in 10.6.2.
(I posted here because it never happened on my other Macs before.)

Just after my warranty expired I developed what I suspect will be an expensive problem. Upon awakening from sleep my computer cannot recognize the internal HD. I total freeze. If I power down & reboot everything works. If I boot the computer from an external HD clone of my internal HD a can put the computer to sleep and wake up without a problem EXCEPT:When I do this the computer removes the internal HD icon from the desktop and Iget a dialog box informing me that the internal HD was improperly disconnected.

I have a 24" mid-2009 iMac, bought in June. It's behaving oddly over the past week or so. It fails to wake on sleep on the first attempt, but always succeeds on the second. When I say fails though, I mean that it *does* wake up, but goes back to sleep again after a few seconds. The other issue happened today, when I woke it up, in a cold room, the fans started up at full speed (I assume). It sounded terrifying to me as my iMac has never got that loud - not even playing games. I restarted it and it was the same, but died down after a while.

I'm not entirely sure how long my iMac has been doing this, maybe two weeks? When I try to wake it from sleep, the screen does not turn on. At all. At first I thought this was because my mouse and keyboard might not be functioning correctly, naturally the only remedy was to turn the computer off with the power button and to restart it (which took an abnormally long time). Today I remote connected with Back to my Mac screen sharing and it did not turn on either. I know it was awake because when I pressed the brightness buttons on the keyboard, it responded on my MBA's view of the screen. Normally, Back to my Mac does turn the screen back on. Anyone else have the same problem? It doesn't seem to matter WHEN it goes to sleep either. I've tried resetting the PRAM already and no dice.

I have an Intel Imac G5 2.66 gHz 2 core duo running 10.6.3. I am unable to get it shut down or sleep. Choosing either results in the display blacking out, the fans run for about 1 second and then everything come back on as if nothing has happened. I've reset the Pram and Vram, disconnected all USB and Firewire devices, tried it with and without file sharing and Airport operating. A 'hard' shutdown with the power button works fine. I have checked for any firmware updates but mine is fine. This happened once before and clearing out some files from deleted apps cured the problem but it's back now.

I used to have a wireless Logitech mouse that drained batteries if you didn't turn it off manually every time you finished using it. So I'm wondering about the Magic Mouse...
1. Does the Magic Mouse automatically shut off when the iMac goes to sleep or is turned off?
2. If I leave the Magic Mouse on (while the computer is off) will it drain the batteries?
3. What do you recommend is best for the batteries and mouse? Should I turn it off every time I go out for the day?

This started after i installed boot camp. I partitioned the computer but didn't restart through the program, i left it for a few days and over those few days when i shut down it booted up again. After those few days, i installed windows 7 but It still keeps restarting quite often on shutting down and I don't know how to stop it.

iMac 27 locking up after sleep mode requiring full power shut down and rebooting in safe mode then shutting down and rebooting normally.. Permissions and this check show no errors, the only error sleep mode failure. Boot up is very slow as well as wake up when possible is slow. Yosemite seems to need a new release in order to correct the boot problems. System operates more like a Windows machine than Apple machine what's going on?
Info:
iMac, OS X Yosemite (10.10.1)

There are times when my iMac will wake from sleep for no apparent reason. Sometimes, several times a night. The glare from my screen often wakes me. If I get up and select Sleep again, it performs normally but may wake up again. I have "Wake for Network Access" turned off, so that shouldn't be it.

It all started a few weeks ago. Whenever I put my Mac to sleep, most of the time, it immediately wakes up again. (Eventually, the fans would start to spin up, but I solved that by disabling "Sleep hard drives when possible"). Now it's just a matter of how I can put my Mac to sleep, and keep it sleeping until I choose to wake it up. I recently got a new printer hooked up to the network, and originally thought it was the issue, but I don't think so now.
I've tried disabling wake up on network access, Bluetooth wake-up. I tried a Airport connection instead of Ethernet, and have disabled both. I even tried unplugging the Ethernet cable, along with any connected peripherals (except the keyboard). Now, my only guess is that it's a software issue, but I don't know where to start. I would love to see my Mac sleeping peacefully again.

I am having a problem with my Mac Pro waking from sleep spontaneously at night. It doesn't always do so, but when it does it seems to be at the same time, 00:42. This morning I opened console to see what was going on at this time and this is what I got: [Log] So it would seem that eye tv is the culprit. I then went to open the com.apple.AutoWake.plist in the System Configuration folder and found 2 entries for EyeTV under wakepoweron which correspond to the times listed above (i.e. 09/24/08 00:42:30 and 03/31/32 06:00:00). I have tried dumping the com.apple.AutoWake.plist into the trash and then restarting, but a new file is generated with the same entries, and also opening the com.apple.AutoWake.plist to delete the entries, but then get an error saying I don't have appropriate access privileges to save the file (even when I change privileges under 'get info' to read/write I still get the same error message).

It wont wake from sleep and after I reboot it, it wont even start. After the chime, the screen stays blank and the fans start roaring high after a few minutes. I brought it to the Genius Bar. They ran diagnostics on it and concluded that the problem is the 3rd party RAM. I then removed the RAM when I got home and it worked for a day. Now, the problem is back. I already reset the the VRAM and the SMU. I'll bring it back today to the Apple Store but I dont know if they will even entertain me this time as they didn't even charge me for running the hardware diagnostics last time.

I just occasionally have noticed my Blackbook, running 10.5.6, when I open it after closing it and moving elsewhere say, may have lost a lot of it's battery power. I think what's happening is it's not going to sleep properly (or it's waking up) when closed. This of course leaves me with not enough power (today 8% when I opened up). What concerns me much more is that the HD arm might not be in the parked position and damage could result with me travelling around. I have in fact had two complete HD failures in 2 1/2 years (though I have no reason to believe this is the cause, in fact I doubt it). I'm aware I can press the power button then select SLEEP and I often do when I'm just charging at home and want to keep the temp down (it's hot here!). Very interested to know what's going on though.....in fact interested in the bigger picture of HD arms when the things spinning as I use my Macbook outside and on my lap a lot, and can't help some movement of course. I emphasise when I shut the lid it normally sleeps as normal, this is just an occasional thing. So is it dangerous, what's causing it, and what about the bigger pic on HD arms when moving the laptop around?

My girlfriends Air has suddenly gotten a weird problem lately. Every now and then when she wakes it from sleep it seems to think that it has a second display connected to it. Even rebooting doesn't always solve the problem.
She has never used an external display with it before. The port looks clean (I thought there might be something there causing a short) and as far as we know there hasn't been any tinkering with any system files on her computer.
Anybody ever heard of this problem before? Or have any idea how to fix it?

I recently bought a second hand Powerbook G4 1.67. It came without a hard drive so i put a new drive in and installed Leopard on it. The problem, before I upgraded it to 10.5.7 sleep mode would work fine but since the upgrade after waking up from sleep only the mouse will work and the rest of the screen is frozen. Anyone else have this problem or know of a fix?

My 2.3 GHz i5 13" MacBook Pro Early 2011 goes to sleep whenever I boot it in clamshell mode with an external display, mouse and keyboard attached (it sleeps right after the boot sequence). Is there any way to prevent this, as it is very annoying when restarting.
Running OS X 10.9.3
When booting from an external firewire drive, on which I have OS X 10.9.3 installed, my Mac completes the boot sequence without going to sleep. I have run the OS X installer over my current installation, (without wiping), and the computer still goes to sleep once the boot sequence has completed.

I am not sure if this is related to the other wifi issues posted on this thread. I am hoping it is an easy Leopard configuration thing. But my wifi used to work perfect--until I patched my OS version. Now, whenever open the lid, it can never connect to my wifi router immediately like it used to do. It spends cycles hunting, and I end up having to manually go into network preferences and try a few times to connect, including rekeying the password.

I had this problem since I used the power schedule to shut down my mac a day after I went on vacation. Now every morning I see the macpro awaken from sleep mode. The mouse is in it's stand so it can't be that. I disabled everything in power settings.

I have a late 2008 macbook, and occasionally after going into sleep via closing the lid or according to the sleep timer, it doesn't really want to wake up. I open the lid/press spacebar and the computer sounds like it's waking up, the keyboard lights up, but the screen stays dark. I've tried waiting for up to 30 seconds before eventually I just hold the power button and hard reset. Upon restart, there is an error message stating that os x crashed. I haven't been able to let it sit for more than a minute or two, as it usually happens when I'm getting ready to give a presentation or something, fun right.

I have a 2.4 Penryn black MacBook. It's been waking up on it's own, overheating and shutting down since I installed 10.5.7. This happened when I first got it, and I took it to Apple. At that time, seems the RAM wasn't seated properly. It hasn't been a problem again until now. Yesterday, it did it twice. The RAM seems to be seated properly. Is there a firmware update or something I'm missing?
