I got my new 24" iMac ~2 weeks ago, and it's AMAZING compared to my MB... Except the fact that the computer will randomly wake up or start up in the middle of the night. The first night I had it home, it turned on 7 times! The next night, it did it once and I turned it off. It stayed off. The day after that, I turned it off when I went to bed. At 4 AM I hear "DONG!!!!!!!!" Ugh. I get up, and turn it off, only to have it start up at 5 AM. x_x I spent the next day looking for answers, I turned off wake for ethernet network something, and turned off screen sharing, quit all programs, and turned off the Airport card. Still, at 3 AM, it wakes me up. I turn put my jacket over it so I can get some sleep. I've been fighting it every night. I'm tired of it. Yesterday I reset the SMC and PRAM, and it still woke from sleep.
I recently replaced my internal hard drive in my 20" iMac and it worked beautifully for about a week.Then, suddenly it started making a horrible clicking noise upon startup or when waking up from sleep.It goes on for about 10 minutes and then eventually tapers off and quiets down.But it happens every time I start up the computer or when I wake it up after it's been asleep for a while.I don't seem to be having any other problems with the functionality of the computer.Everything is accessible and working OK on the computer.I am just worried because many years back when I had a PC the internal hard drive failed after I heard a similar clicking noise, although it's been going on for a few weeks on my Mac without worsening, and my PC hard drive failed within a couple of days of the start of the clicking.
Is it possible that this is a fan or some other internal mechanism that possibly got jarred or moved slightly when I replaced the hard drive?Or a bad hard drive?I don't really want to open up the computer all over again but at this point, I suppose I have to.I am just not sure what to look for when I do.urls...

Like, when the gray screen turns on, it has a reddish hue. after a couple minutes, colors restore to normal.
then if my screensaver kicks in, and I wake it up, even immediately, I can see that reddish hue and watch it slowly transform into the proper color.
What does this mean? Does it mean that my bought-in-2004 1.33 ghz PowerBook G4 is dying of age? it's nto necessarily the computer itself, but the screen.
y'know how in school, when the overhead projector would start to look brownish? and then a few days/weeks later, *explosion* the bulb has burned out?
I have a 2009 8 cores 2.66Ghz Mac Pro with 16GB RAM and ATI Radeon HD 4870. It keeps waking up randomly from sleep. I have tried quitting all applications before sleeping, but it still woke up from sleep by itself. Anyone has nay idea why it kept waking up randomly?
iMac (late 2012) will not wake from sleep unless I press on/off button. Then the Mac freezes and two messages pop up telling me I have not ejected properly my two external devices 1. 500G HD and 2. 16G Flash Drive.

for a few weeks now my MacBook's been starting up in single-user mode by itself, without me touching anything. The thing is, it only happens about half the time - otherwise it's booting up normally. I wiped my drive and reinstalled Lion, ran fsck and used disk utility several times, but it's still happening.Â

My brand new 27 inch iMac is waking by itself. It has a wireless keyboard & mouse which I have a sneaking suspicion might have something to do with the problem. Or maybe the Linksys router? Would any other Bluetooth device not on the immediate premises be contributing to this? This is strange, I haven't used wireless devices before so it's possible some nuance is eluding me.
We have a family iMac that is waking up on its own.Â
27" Mid-2011
3.4 GHz i7
10.9.4Â
Pretty clean system, as I don't have a lot of software loaded. My son usually uses it for games, Minecraft mainly.Â
The last couple days it has been waking up on its own with no prompting. I checked the usual suspects, "Wake for network access" is not clicked, bluetooth is off and there are no sharing services that have been clicked on.
When I check the console, the only message that shows up during the self wake is:Â
"8/21/14 11:20:06.960 PM Console[309]: setPresentationOptions called with NSApplicationPresentationFullScreen when there is no visible fullscreen window; this call will be ignored."Â
This keeps appearing at the time the self-wake up occurs.Â

I have a G5 iMac - 2.1 ghz, 20", 250gb hd and 3gb ram, but it has been having problems starting up and it is also going to sleep midway through a task or at random times totally unprompted.
It now almost never starts up first time (I keep the iMac mains power lead always connected and the mains electricity supply turned on at all times now)- sometimes I will get the 'Start-up Chime' and then the cooling fans start spinning very loudly and then after a few seconds the iMac stops the start-up routine, but often when I try to start-up I don't even get the 'Start-up Chime' and I have to leave it for some time before trying again.
I can also now only get the iMac to run as a Firewire Target Disc by starting up with the T key held down and then using an old G4 (400mhz) Powerbook Titanium as the screen/keyboard by using the iMac HD as the startup disc for the Powerbook but this is obviously just a temporary work around.
I have also tried backing up all my data, and reinstalling the Mac OS X onto the iMac but the iMac still will not start-up normal and I still have to use it just as a Firewire HD.
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.
I don't know if this has been discussed here but all of a sudden my iMac, running Snow Leopard, 10.6.1) keeps waking up all on it's own. I believe this started after the latest update of Java and Super drive firmware (I believe these were the latest updates).
Is there anything I can do short of shutting the computer down.
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.
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.
I am running OS X 10.9.4 Mavericks on a 27-inch Mid 2011 iMac. Prior to upgrading to Mavericks, I would go to System Preferences_Energy Saver and set Display Sleep to 1 minute. This would keep the computer screen turned off at night, but would allow for backups with Carbon Copy Cloner to function. (My Computer Sleep setting is set to Never, Put Hard Disks to Sleep when Possible is checked, and the remaining two items Wake For Network Access and Start Up Automatically after a Power Failure are not checked.Â
However, after the Mavericks upgrade, my iMac wakes itself up without any prompting. This occurs when there are no other programs running. Even after putting the machine to Sleep from the Apple Tab, it still wakes itself up with no programs running, etc.Â
I also checked the settings in System Preferences_Accessibility and the Voice Over, Captions, and Speakable Items settings are off.Â
After running the Terminal Application with the command line syslog |grep -i "Wake reason" I get the following results:Â Â syslog |grep -i "Wake reason"Aug 28 00:34:54 kernel[0] <Debug>: Wake reason: EHC2Â My understanding is that this means that a USB connected device may be waking the system. Accordingly, I disconnected all USB devices (forgot the devices in USB Preferences), except for my Wireless Apple Trackpad. However, the same problem occurs.Â

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.
did a quick search on Apple, and here but didn't turn up much of anything useful. I've got a friend with an iMac that won't boot up. Pressing the power button doesn't seem to do much of anything. I've tried unplugging the power cord, and re-plugging it, but alas, I got the fan to rev up for a second and then blahh, nothing again. It's a 20" model with the black bezel. Not entirely sure of the system specs, I only got a couple minutes with it last night. Do these machines have any common problems like this?
This happened many months ago but my imac evetnually started. Today I have tried several times to start my imac and can't get beyond the white screen.I get the mac sound at when it is trying to start up but then freezes at the white screen.
When I start my iMac, a few programs start along with the computer. I don't want any programs starting by default. I have reviewed the Preferences of these programs, and see nothing to uncheck regarding auto startup. And I don't see anything related to this in System Preferences. How I can start the computer without programs starting with it?
I hear 3 beeping sounds when i start my mac OS X. It just shows a blank light blue screen. I have not updated it in a long time. I have a Imac "20" inch
