I have noticed my iMac waking up in the middle of the night when it's sleeping. It's not real loud or anything, but I am a light sleeper and it wakes me up, sort of like a Twighlight Zone episode. Does anyone else notice this? Could it be spywre?

My iMac seems to wake up often in the middle of the night and in the day when I'm at school. I was wondering if there's an app/pill that can attempt to do the opposite of Caffeine: keep my Mac asleep at night. Does anyone know of such a thing? I doubt it exists, but then again sometimes I doubt I exist.
View 8 Replies View RelatedI have been shutting down my MacBook Pro OS X10.7.3 at night.I just read that OSX runs "maintenance" procedures early in the morning (between 3:15 am and 5:30 am) and that if Mac is powered off at that time, that these maintenance procedures will NOT run.True or False? AppleCare says that it won't make any difference and I won't be affected if these night procedures never run. But, if that's true, then why are they set up to run at night? ? I went to the Apple Manual but it does not address my question.Â

I just bought my Intel-based iMac last night and it took forever to turn on out of the box. I guess I made a mistake by doing a "soft" power down last night, because this morning it will NOT turn on. I've tried using the power button and waiting. I've tried unplugging and plugging it back in, and then using the power button, and waiting. Nothing works. I've been a PC user for 20 years and just bought this, my first Mac, last night. I think I've made a huge mistake! How the heck do you turn these things on????

When my computer goes to sleep it will not wake up, and I have to shut down using the power button on the back and then restart. I called support and they advised me that this only happened when the computer went to sleep on it's opwn but not when you manually put it to sleep, But that proved not to be true. It will not wake up under either situation? The support persontold me to logonto applke and re-install the sytem software which I have done but that did not cure the problem either. I have my preference set to never sleep. I am ar]t a loss as to what to do now as when it goes to sleep or I put it to sleep i sometimes will not start up even after shutting down and restarting.I am on 10.7.2?

My iMac won't start up, or wake from sleep. I've tried everything, except for reinstalling the SO-DIMM memory modules. Still, my iMac will not wake up. Turning it on, you can hear the fan run, but the display stays dark.Â

My Mac would not turn on this morning from sleep mode. I pressed the power button and nothing. Then I did it again and heard the fan shut off inside so I tried again and up it came. Also I cannot wake my Mac up unless I press the power button. I used to press any key on the keyboard or move the mouse and it would wake up, but now that doens't work. I don't know if this could be a reason, but my mother has a horrible habit of unplugging it when it storms. It's always asleep and I've told her not to do that and to make sure it's turned off before ripping the cord from the wall. But she continues to do it when it storms.

I have an imac early 2009. I have recently updated various software from Apple. I have the engery prefrence at : 1hour Computer sleep and 15 mins Display sleep. I use Gotomypc to login to my home computer. Prior to the new updates i did not have an issue with with the computer not waking from sleep. But since the updates my display will not wake? They hardrive wake but the screen just does not. I do have a screen saver, however, this was not an issue prior to the new updates.
View 3 Replies View RelatedComputer 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.

cant wake up imac from sleep after lion upgrade

Ever since I bought and downloaded OS Lion, whenever I put my mac to sleep or it goes to sleep on its own it occasionally won't wake up from sleep. It has to be manually rebooted. Is anyone familiar with this problem. Apple must know about it by now. I'm not lugging my 27" iMac into the apple store to have them look at it unless it won't reboot. Hoping it doesn't come to that...anyone familiar with this or have ideas on how to fix it? I don't know if it's a 3rd party software issue or just the OS.

Looking at my console log I see that my computer is being woken up repeatedly by Time Machine.Since I don't backup every hour this seems to be a wasteful interruption to Sleep Mode, and effectively disables it; not something I want. The console message I see is "Not starting Time Machine backup after wake"..Is there a parm that I can set somewhere to prevent this? I have "Don't wake for network access" set but that seems to affect incoming rather than internally

My screen on my 2 week old iMac comes up pixelated leaving square trails mimicking the movement of the mouse. I have had consultations twice with Apple support junior team members, looking forward to a senior team member reviewing my case. It looks like some sort of eraser wiping the blank dark screen revealing the login screen underneath.
Oh by the way my first iMac was sent back due to dead pixels, how unusual is that?

I leave my imac on all the time, I have a wireless bluetooth keyboard and sometimes when I hit the keyboard my imac doesn't wake up. Is this an issue that anyone else has delt with? Is it a keyboard issue or a computer issue?

This just started yesterday (May 31st). I keep everything updated as it comes out and nothing new has been installed in the last couple of days.
When I need I wake up my iMac (now requiring a keystroke or mouse press instead of just moving the mouse), the screen comes up black, but the cursor is there and moves around fine.Â
It stays black for a while (15 seconds or longer, but it feels like forever) and then it finally comes up completely.Â

I just purchased a set of Mushkin Apple 8GB (2x4GB) DDR3 1333MHz SODIMM 9-9-9-24 (976647A) RAM for my mid 2011 27" iMac and everything ran great for a few days. I was able to sleep and wake the machine with no problems. Last night I was doing some graphic intensive work on my machine and when I had finished, the fans were still running high but I was going to bed so I put the machine to sleep. Normally the fans would stop at this point but they kept running. I assumed the machine was still hot so it was just cooling after sleeping. The next morning the machine would not wake. I had to do a hard reset to get it to boot up again I tried resetting the SMC and PRAM but it still doesn't wake from sleep. Am I have issues with my RAM?

I ordered an 24" iMac with 2.93 GHz (I think thats the number) and I am supposed to get it today. Anyways. I was wondering if it is safe to keep it on all night and never turn it off. Will it become slower? When should I shut it off?
View 24 Replies View RelatedI'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all.

My iMac is set up wireless. Every time it's allowed to go in sleep mode, it loses wireless connectivity. Then, when I wake it up, I must go to System preferences, Network and request it to reconnect to my home wireless network. It always does this successfully, but it's quite annoying that it seems unable to achieve this on it's own. My iPad 2 and kindle can do this, why not my iMac?

I'm using 2 IMac 27' and one is simply used as an external display. When I wake up the computer from sleep, it works on the main monitor, however the external display still has a black screen. I have to unplug the external monitor to get it to wake up. I tried unplugging thunderbolt and replugging it in which worked the first time, but same issue again not waking up.

I have a new MBP 13". When I'm using the Mac it's mostly connected to AC. Over night it's mostly sleeping without the AC connected. My question is, if I should let it sleep at night or should I shut down the Mac regarding to maximize the battery life?
