OS X :: Mac Wakes Up On Its Own - Any Way To Check Log
Feb 5, 2008
My ALU iMac seems to be waking up sometimes (so not all the time) when I'm at work. I am 100% sure I set it to sleep and everyone else in the house says they didn't touch it. My work schedule is always about the same, so it's strange that 2 weeks ago it was awake when I got home, and since then 2 times more. I've checked the settings, to be sure it doesn't have a schedule to wake and sleep. Everything looks OK. No schedule whatsoever, except wake after power failure.
I've disabled that now but I don't think we had any power failures recently because iStat Pro indicates an uptime of 20 days straight, which would be hard to do without power. Now is there a way to check any logs about wake and sleep times? I'm sure there is a command for the terminal that does exactly this but I haven't found it yet. I ordered the Missing Manual to learn more about OS X but I would like to check this now because the order could take a while.

I have a new MacPro set to "sleep" at midnight. The past few nights at about 1 am and 3.30am the computer wakes itself (and me) up? Why is it waking?

I see my screen popping on for no reason staying on for 5 minuets or so then going back to sleep. Is this normal? I don't recall it doing this before but I have added an old p.c. to my network and got an iPad. Don't know if ether of those things have any relevance but like i said, I don't remember it happening before. From what I understand, to get spyware or malware on the computer I need to instal it. But I could be wrong. I have an iMac running 10.6.4.

I've owned my G5 for 3 years and recently when I put it into sleep mode it immediately wakes back up. I have a screen saver password so it asks me to enter the password, if I don't it goes back to sleep, then immediately wakes up. It repeats this process a few times before finally going to sleep. This is very weird because I haven't installed anything or changed any settings.

My MBP sometimes wakes up from sleep for no apparent reason. I have it set up in a closed lid/external monitor mode, with a bluetooth keyboard and a wireless usb mouse. To make sure it's not USB activity, I unplugged all USB devices, and switched the USB mouse off. Also made sure "wakeup on ethernet access" is disabled in system prefs, and software update is turned off. Looking at the console, it woke up with a reason:
Wake reason = EHC2 OHC2
Do you know what that is?
Below is a system.log snapshot and console messages when it woke up. Any ideas about what caused it?

I have a hot corner to put the mac display to sleep. Whether I use that or I use the 3 buttons to put the mac display to sleep, it wakes up after a while (probably due to some activity on the net or msn etc...) Is there a way to keep it asleep until I wake it up manually?

I have Mac mini 2.26 (2009) OS 10.6.3. with apple wireless keyboard and magic mouse. For some time now my mini wakes from sleep for no reason after 20 minutes. I have checked kernel.log and it says that ohc=2 is the reason for wake up. It seems to be bluetooth keyboard or mouse. When I turn off "allow bluetooth devices to wake..." everything seems to be ok. Is there a way to fix this because I would like to be able to wake mini with keyboard.

This is has been occurring most every night since I've had this MBP for a few weeks. I put the MBP to sleep at night. Then some point in the morning, I can actually hear it wake, but then quickly, within 5 seconds, it right back to sleep.
I have no programs telling it to awake or perform scans, my Bluetooth mouse is off, etc. Has anyone experienced this or know how to resolve it?

My Macbook seems to have a life of its own it wakes up by itself when the harddisk is sleeping.When I leave the computer open but the hard screensaver is on or the harddisk is at sleep it often wakes up by itself.Also when I go to sleep at night and I close down the screen and the lid there are sounds as if the computer wants to wake up and this often goes on for up to 15 times in a row.I then have to shut down the computer and disconnect all together.This is really enoying as I am afraid the harddisk will get harmed during the night.I have upgraded to snowleopard and after that this problem started.I did leave my computer to a apple service shortly after I changed my harddisk there after my old harddisk crashed in november last year.But they could not find any problem with my computer.I really would like to now what´s going on.

Whenever I select Apple sleep it goes to sleep but immediately wakes up.
I have taken off all devices and it still happens - but really, it started this after working with the same devices for many months.
It is immediate after going to sleep, the next second it wakes back up.

When I go to bed, I like to just put my macbook pro to sleep by closing the lid. But almost 100% of the time it wakes itself. It gets really hot when this happens so I've been turning it off most of the time instead, but I'd really like to get this resolved. I have an external monitor plugged into it so I know its awake as the screen shifts over to the external monitor. When no monitor is plugged into it, I do occasionally hear the hard drive spin up. I have tried unplugging everything except for the power cable to see if that might help, but the result is the same. I have a 1st generation 15" Macbook Pro running OS X 10.5.3.

I just started having this issue where when i close my powerbook lid to put it to sleep, it'll fall asleep (but takes longer than usual) and then 5 seconds after it falls asleep it'll wake up.
and then i'll open it and sometimes it'll continue to be awake, but sometimes it'll go back to sleep...
I've reset the PMU and the nvram. i've also created a test user account and i have the same issue there so it seems like it's a hardware issue... which really sucks.
does anyone have any suggestions? it seems like whatever makes the powerbook realize it's closed is broken. hopefully that's a part that's easy to replace?

My MacBook Pro has been waking up from sleep at some of the most random times. Usually it will wake up about 5 minutes after I put it to sleep, and if I'm lucky it will stay to sleep when I try again. Sometimes it will even wake up 30 or 45 minutes after I put it to sleep. Currently, I have it connected to an external display with the laptop screen closed at all times. It is running a fresh install of Snow Leopard with barely any apps installed yet (mainly just iWork and Microsoft Offiice). I was having the same problem when I was running Leopard, thats why I did a fresh install. So this eliminates a software issue.
This has been happening for a few months now, but it has just started to become a problem for me. When I was running Leopard I did not have an external display. It was waking up at random times without anything connected to it (no display, USB, or MagSafe connected). I would be sitting next to my Mac, and all of a sudden, I hear the Superdrive wake up sound. I searched and found a thread similar to this, but hopefully it will not have the same solution as the members of the following thread had: "I had this problem with my Macbook. The fix was a logic board replacement." [URL] I have also attached a screenshot of my system.log in Console. I opened up console as soon as my MBP woke by itself. Hopefully someone here will have some idea what all the stuff in console means or maybe be able to narrow down the problem.

I have a mac pro in my studio, hopping on some open wireless network...
I also have an old 12" powerbook.
I understand that I can have my new mac pro (Snow Leopard) sleeping, and have my powerbook hooked up to it with ethernet always on... and be able to wake up the mac pro through something called wake on lan?
How do I set this up? How do i set it up in both osx sl and xp pro?

I can't find any other thread out there about this. I was wondering what the fix for when my iMac 27 c2d comes out of sleep and pinwheels for about 4-5 sec. It only started doing this when I updated to 10.6.2

having a weird problem since my Lion install. It's happening randomly, with no peripherals attached. I will open my MPB as it has been sleeping closed; the passcode screen will pop up but before I can type, the screen goes black and it goes back to sleep. I press keys, click the trackpad, everything I can think of, but it doesn't respond. When I close the laptop, wait a minute, then reopen, the same thing. The login screen pops up but then blinks out black before I can do anything. Â

I've got a dual G5 running Panther and I put it to sleep when I go to work in the morning. Last night, I wanted to try out Tiger (yes, I know - I'm way behind the times) so I installed it on a FireWire drive and booted off it for a couple of hours to see how things worked. I then went back to my internal Panther drive, and everything is ok except for one thing: when I hit "sleep", it goes to sleep, the screens turn off, and then for some reason I immediately hear the internal drives spin back up and the thing turns on again! Why can't it stay asleep?

I've tried all sorts of sleep methods: lid, button, start menu (bootcamp) and even on mac osx. However, it will randomly wake at times which makes it frustrating because I don't want to always shut off my laptop. Anyone have this issue?

I remember a while back ago, well over a year ago I discovered online a software program only for the Mac intended to help people go to sleep and more importantly wake up. It utilized your iSight camera taking a photo (silently) every time there was movement, as the camera was positioned to focus on you sleeping, determining when you would be entering a REM sleep cycle and at what times would be best for the program to wake you up. It was a nifty little program though used a bit of ram to keep up since your iSight camera was on all night. That and the program did a few other interesting things too. I hope someone knows what I'm talking about.
I'd love to check this program out again but can't remember it's name. I'm only doing so since I've moved to a new apartment and am looking for a new method to wake me up in the morning aside from my cell phone's loud ring tones. Or there is this other alarm clock that you set on the opposite side of your room and have a little laser gun next to you and when the alarm rings in the morning you grab the gun and the alarm won't turn off till you shoot the laser w/ the gun directly into the bulls-eye within the alarm itself on the other side of the room.

I'm currently on an internet plan that is divided into on peak and offpeak times. I am coming up to my monthly cap of onpeak and i am either asleep or not home during my offpeak times. I was just wondering if there is an app out there that i can use to easily set my MBP to wake from sleep at like 2 a.m. to start downloads.

Suddenly my new macbook aluminium have started to wake up from sleep mode when the lid is down. It goes into sleep, and then it wakes up again and back to sleep and wakes up again. I have tried to restart SMC, and i have unchecked bluetooths ability to wake up the computer and the ethernets ability to do so.

I have a 27" iMac purchased last January. Every time the computer wakes up, the display activates with normal coloring but after a second "shifts" into a different color profile with a blue'ish tint.
All software updates have been applied. I've reformatted the computer twice since the initial purchase. Problem persists.
I'm well aware of the yellow tinge problem with 27' iMacs, but based on my research of past posts the blue color shift has only been a problem with Macbooks.

I've been using a G4 mini running 10.4.11 for web surfing, email, and document scanning for about 4 years with few issues. Recently, though, it loses its wired ethernet connection when I wake it from sleep. No ethernet device appears in Network Preferences/Network Status, and Network Utility shows the ethernet connection as "inactive". If I disconnect the ethernet cable for a few seconds and then reconnect it, the ethernet connection reappears in Network Preferences, goes "active" in Network Utility, and functions normally.
Once ethernet reappears, I can wiggle, tug, and disconnect/reconnect the cable and maintain the connection. The cable works normally with another computer. So it doesn't seem to be a hardware connection issue. The network has 2 other wired computers attached with no issues (an old homemade PC and a Mac Pro) and several other devices via both wired and wireless connections. So I don't think it is a router or dhcp issue. I don't recall installing any new software, although I install all Apple updates (including iTunes) when they become available.

Several times my MBA (mid 2011) woke up by itself after setting it to sleep within a few seconds. Following appeared in the console:
kernel: Wake reason: EHC2kernel: The USB device HubDevice (Port 1 of Hub at 0xfa000000) may have caused a wake by issuing a remote wakeup (2)kernel: The USB device Apple Internal Keyboard / Trackpad (Port 2 of Hub at 0xfa100000) may have caused a wake by issuing a remote wakeup (3)
I did a few resets (SMC etc.) and reinstalled Mac OS the first time. It didn't work. Then I did this all again and reinstalled Mac OS a second time. Both times I wiped the SSD. Now my MBA doesn't wake up again by itself. The Apple Hardware Test also was completed with no issues. But the above posted logs still show up when a wake it up by hitting the keyboard. Are these logs failure warnings or normal entries?
