OS X :: Mac Mini Wakes From Sleep
May 8, 2010
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.

I have an obscure brand USB keyboard that I am trying to use with my Mac Mini, with one problem: after the Mini goes to sleep and wakes up again, the keyboard doesn't work. The solution is to either unplug and replug the keyboard or restart, but both are I think unnecessary hassles.
What I like even more is that the keyboard will wake the Mini (by pressing the spacebar or something), but won't work after that.
I also tried a plain ol' Apple keyboard, which works just fine after sleeping/waking.
Any ideas on what's going wrong, or how to fix it without replugging/restarting? It's just a keyboard, so I don't see why it should pose as any real problem after waking, so buying a new keyboard is not quite what I am looking for. I may end up doing it anyways (a wireless one to go with the wireless MX1000 I am using) but at the moment I don't want to spend money for a new keyboard.
It's a 1.66GHz Core Duo, 512MB RAM, 60GB HD, OS X 10.4.10.

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?

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?

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.

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.

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'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.

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?

Since I've upgraded from MacOSX 10.9 to Yosemite, my MacBook Pro wakes from sleep within 30 seconds. I've tried solutions suggested on Google, but they have had no effect (and usually are about MacBook's waking up after 2 hours).Â

To figure our what is going on I've started OSX in safe mode and logged in using the guest account. Also I've turned off WIFI and Bluetooth. The problem still occurs. The syslog shows relatively little from the moment that I select 'Sleep' and the computer wakes again (see below).

My macbook has developed a problem where when the lid is shut and the power is connected it wakes up from sleep and then goes back to sleep and repeats this process every 30-60 seconds.
What's weird is it doesn't wake from sleep and get stuck in this loop when�the lid is open and the power is connected and I select sleep from the Apple menu�when the lid is shut and the power is NOT connected and is running from the battery
I recently updated my mac to Snow Leopard and put in a new HDD and since doing so the problem has been occurring.

I'm running Windows 7 with boot camp on my unibody MacBook Pro.
Quite often, I'll close the lid to put it to sleep, then, a few minutes later I'll notice that the Apple light has turned on, and when I open the lid I confirm that it's woken up.
In Event Viewer, I've noticed that every time this happens, the following event is listed, in the Power-Troubleshooter category: "Wake Source: Device -USB Composite Device".
I have no USB devices, ExpressCards, CDs, or anything plugged in.
EDIT: It doesn't only happen when it's running on battery power, since it just happened with the AC adapter in.

I have a macbook pro mid 2012 mode, when ever my laptop wakes up from sleep after a longer duration then the screen flicker and vertical color lines appear. Â
The problem goes away once I reboot, also the problem doesnt appear in case I dont let the mac sleep. I have tried PRAM reset and changing my display resolutions, but both have not worked. The mac is just under two years old and I have already replaced the SATA cable, hardrive and now this issue?Â

I recently bought a 1st generation 500GB Time Capsule as I don't need the dual-band functionality of the 2nd Generation. Since setting it up I've been having a problem, whenever my iMac sleeps from a long period of time the backup is delayed when I wake the computer up. This would be less irritating if the backups continued like normal after the computer was awake, but I have to keep re-starting the backups manually to get the backup schedule back on track. This is especially frustrating as the whole point of the system is so I don't have to worry about manual backups.

Since installing Snow Leopard, I have noticed that my Mac will wake randomly. It does not happen all the time, but it does a lot. I have tried to reset the PRAM and it did not help. The "Wake for network access" option in Energy Saver is unchecked. Any ideas?

I've been experiencing this issue off and on for about the past 10 months. I just upgraded to Snow Leopard tonight and the first time my Unibody MBP's screen saver came on and I got it back to the desktop the entire tint of the screen is intensely cooler. I have to go to Preferences>Display>Color and it automatically goes back to normal. The original "Color LCD" is highlighted, so it's not as if an entirely different profile got selected. If I click on Adobe RGB (1998) I get the exact same cool tint that I get when I unlock after the screen saver appears. Once again, it doesn't happen every time, but it does happen enough to sort of worry me.

I own a early 2011 edition of MBP, with 2.3 Ghz i5 processor and 4 GB ram. Everytime it wakes up from the sleep mode, it heats up with the internal fans constantly on.. Moreover, the estimated battery life shows as 2 hours even when the percentage is 97%.. However, when I restart the MBP, the heating stops and the battery life shows 5 hours..

My iMac is waking up from sleep in the middle of the night. The only clue to what is going on is that is says the wireless keyboard has lost connection.

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.
