IPad prevents MBP from sleeping

I recently noticed that my MBP was no longer sleeping. It would get to the almost asleep state - where the light was very dim - but not pulsing - and stay there.
I shut down all programs on the MBP and made sure that the Preference for Waking on Ethernet Access was not checked.
It still would not sleep.
I finally solved the problem by asking what the last thing I did was, before I noticed this issue. I bought my iPad.
I also noticed that the router lights for the MBP were active, occasionally flashing. Normally they go out as the MBP goes into the sleep mode.
Solution:
The iPad is apparently networked with the MBP, either directly via the WiFi or via iCloud.
By turning the Airplane mode ON on the iPad, my MBP quickly went to sleep. The Airplane mode turns the WiFi off and thereby disconnects it from my MBP.
So if you have a problem with your Mac not sleeping properly, try turning the Airplane mode ON on your iPad and see if this does not fix the problem. It works for me...

These commands:
sudo sysctl -w net.inet.udp.log_in_vain=1
sudo sysctl -w net.inet.tcp.log_in_vain=1
will give you output like the following in the console log:
01-10-12 20:20:45,000 kernel: Connection attempt to TCP 192.168.1.17:554 from 192.168.1.15:37481
In my case it was Synology Surveillance station trying to connect to port 554 on my laptop...
Don't forget to set the variable back to 0 after you found the problem!

External display prevents MBP from sleeping.

I have a Mid 2012 Macbook Pro (Yosemite 10.10.1) with a ASUS VS247 display connected via HDMI to Thunderbolt using an AmazonBasics Mini DisplayPort to HDMI adapter. When I put the MBP to sleep (closing lid or selecting Sleep from the Apple menu) it is never able to fully sleep due to wake ups from EC.DisplayDetach/Maintenance. Below I have pasted the results from pmset -g log. You can see the wake ups (DarkWake DarkWake [CDN] due to EC.DisplayDetach/Maintenance) occurring approximately every 30 secs to min. These wakeups during "sleep" do not occur if I don't have the external display connected. Has anyone experienced a similar problem and have a solution? Does anyone have a similar configuration, but does not experience this issue? Any help is appreciated.

How to stop my Time Machine external hard drive preventing iMac from sleeping?

I have a late 2012 iMac, and have discovered that sometimes (I haven't noticed a pattern of when it doesn/doesn't happen) the computer will immediately wake up after I set it to Sleep (Apple Menu>Sleep). Through elimination I have found that it is the the USB 3.0 external hard drive I use as a Time Machine back-up that is the culprit; unplugging it then allows the computer to sleep. If I unplug it, then plug it back in later on, this normally solves the problem for a while, but not forever. This same Hard Drive didn't cause the wake problem on my previous '08 iMac.
A big issue is that when the machine immediately wakes from sleep, the display stays off (until I move the mouse) - this is good from a power saving point of view, but means I don't know if/when the machine is immediately waking from sleep (I have to listen to the fan when setting it to Sleep mode to hear if it has actually woken back up).
I've searched the forums, but can't find another poster with the same problem as myself. Can anyone advise a course for me to pursue to prevent this from happening?
Thanks. Jamie

Hi Frank. Nope, I'm still having the same symptoms; the plugged in external drive (TIme Machine) will wake the machine up a couple of seconds after it winding down when put to into sleep mode. Ejecting the drive and then sleeping the machine works. After plugging it in again to do a Time machine backup, it will allow the computer to sleep soundly for the first few sessions (eg a few days of sleeping, waking, sleeping, waking, etc), but then it will then suddenly start preventing it from sleeping again after a while.
It seems I'm fortunate in my case that the display stays dark (or off?) when the machine has been woken from sleep, but this was actually preventing me from knowing the machine wasn't in fact asleep for quite some time; I only eventually cottoned on because there wasn't any delay when 'waking' my machine (which there normally is). I would then have to carefully listen to the spinning fans to know if in fact it had gone to sleep or not.
So, to summarise, unfortunately no, I haven't solved this yet. If anyone else has a solution, please let us know?
Also, I've noticed occasionally after waking that there is a relatively quiet 'crackle' sound (kind of electrical sounding) from the bottom-right area of the machine. This goes on every so often for about 30mins. I see this is also an issue with other people's late 2012 iMacs, but I've not seen if anyone has a solution to it?

How to prevent computer from sleeping when downloading Lion from the recovery partition?

Hello,
I just got a new MacBook Pro that came with Lion. I'm reinstalling from the recovery partition and I'm on the downloading additional components stage. It has 3 hours to go and the computer keeps going to sleep. How can I prevent this? I don't want to have to babysit the computer for 3 more hours.
Thanks.

Looking for an answer to this question now. Did you find one? I'm about an hour into a 6+ hour reinstall of Mountain Lion from the Recovery partition on my MacBook Pro. So I can't change the sleep corners or caffenate it or do much of anything but wait. I want to go to bed and let it install overnight, but I assume it will go to sleep, and that will kill the download. It there any way to prevent it from sleeping now?
Even trying to think of something I can put on the trackpad to trick it into thinking I'm touching it.
Maybe ill put it under my dog, and her movements will keep it awake? Thinking outside the box here.
Any ideas would be appreciated.

Not detecting external display after waking up MBP from sleep mode

I am a recent owner of a MBP and enjoying it. However, one problem that I can't seem to find a solution to is the external display problem after sleep mode.
When I first boot up the Mac and plug in my Dell external monitor via the mini adapter, there is no problem with detection or display. However, every time I put the MBP in sleep mode and then wake it up again, the external monitor does not "wake" up and my MBP only displays my normal screen on the Mac.
I tried to 'Detect Displays' to no avail and the only solution is unplugging the mini connection and plugging it back into the MBP for the MBP to re-detect the external monitor.
Although this is a quick fix in itself, I do not want to wear out the mini port by doing this every timeI come out of sleep mode. Any solutions so that the external monitor will detect the MBP waking up from sleep and display properly? Thanks!

And same problem here.
Using a MBP 2.66 i7 with a Dell 3008WFP that's connected to the MBP through DisplayPort. It works some of the time but once in a while (only been using the new MBP for a couple of days now) the monitor won't come out of sleep mode. Turning it off/on causes OS X to completely ignore the monitor. I was able to get this setup to work again by pressing 'Detect Displays' in the System Preferences pane but most of the times that doesn't help. The only sure way to get the monitor working again is by booting into Windows through Bootcamp, Windows is able to use the monitor, if I reboot after that OS X sees the monitor again.
Also saw a magenta line/stripe on the left side of my monitor and the monitor sometimes makes a buzzing sound when connected to the MBP through DisplayPort. That's what you get by using bleeding edge tech I guess :\ Only alternative is buying the mini-DP to dual-DVI connector but paying $99 just to be able to use an external monitor is rather insane. Besides that lots of users are having problems with this adapter.

Prevent MBP13 from sleeping when closed power & ext display?

hi all,
i use my macbook with an external monitor and keyboard. i normally have my macbook charging and the lid closed.
i unplugged the mag charger and my external monitor went black. however when my lid is open and not charging everything works fine.
so my question is why does everything work fine when my mac is running on power and lid closed but does not when lid is closed and an running on battery. (however does when lid open running on batt)

Hi Radium88,
You can prevent your MacBook Pro from going to sleep using the steps in this article -
OS X Mountain Lion: Prevent your computer from sleeping
http://support.apple.com/kb/PH10679
Specifically -
Choose Apple menu > System Preferences, and then click Energy Saver.
Drag the slider that controls the computer’s sleep to “Never.”
Thanks for using Apple Support Communities.
Best,

What is that sound effect when you wake the MBP from sleep?

There is some sound effect every time I wake the MBP up from sleep. I am not sure what is making that sound. It sound like "pffft", I hope that makes sense.

Hi I hve the same problem mi MacBook Pro doeas that, the sound that makes is the one I have for default, Funk (for example if my computer sleeping with the screen open and I press any key on the keybord it makes that sound) if you want you can try this, to chek if that is the sound that you heare, close all the windows and try to use expose.
remember the sound that you are going to heare is the one that you have for default.
Another thing is that I re-instal the OS and the computer stops from doing that but then start again when I eject my iPod from the finder window but I left it conected from the USB and then when the computer was sleeping I desconected it.
I know that maybe nothing of this can help you but I want to let you know that you are not alone.
If you found the fix for that thing please let me know.

Restore disk OS X Mountain Lion: Prevent computer from sleeping

Please help, I need to create a backup using the disk utility on my restore disk. However, the computer keeps going to sleep and corrupting the backup. How do I prevent my computer from sleeping while the imac is creating the backup?
Processor 3.06 GHz Intel Core 2 Duo
Memory 4 GB 800 MHz DDR2 SDRAM
I can not add anymore physical ram
Graphics NVIDIA GeForce 8800 GS 512 MB
Software OS X 10.8.3 (12D78)

I would recommend using a proper tool for backing up, if you want to create a bootable clone use either SuperDuper or Carbon Copy Cloner. Either that (or even better use a clone and) or use Time Machine.

Stop MBP from sleeping when lid is shut - for watching movies on Apple TV

I recently bought a MBP and Apple TV both work fine but because the MBP is connected to an external monitor, the MBP is always in clamshell mode (lid is shut) So the thing keeps going to sleep when I'm watching movies on the TV screen. I have the 'wake for network access' set to on, this doesn't seem to work either.
Basically how can I keep the MBP from going to sleep when the lid is down and no activity has occurred, so I don't have to get up halfway through a movie to start up the Mac again, cos the homesharing connection has been lost because the MBP has gone to sleep again!!!?
Thanks

Is it possible to set up the mac against one user account so that when that account is open the macbook does not go into sleep if the macbook lid is shut? However I would want the other user accounts to set the mac to sleep if the lid is shut.
You might be able to do it with Insomniax. I haven't tried it in the way you asked but it might be able to if you se it up to run in one account and not the other.
Also is it possible to tell the mac to go to sleep if the lid is shut when running on batteries but to stay awake with the lid shut when running on mains power?
None that I know of.
The MacBook will go to sleep if it is connected to an external monitor and you close the lid. Once it is closed you can wake it up and use it. The two links referenced in the other post show how to do this. You can also do it with just a wireless blue tooth mouse and no external keyboard. Just set it so the bluetooth devices will wake it. You also can use your Apple remote to wake it with an external display connected. It will allow you to use Front Row with the lid closed on the external display.

Clamshell Mode Prevents Waking from Sleep

I've got a MacBook Pro (Intel, 2.33GHz) running 10.5. Since installing Leopard I've been bumping into periodic issues with trying to wake from sleep while in clamshell mode. (I've got a Samsung LCD monitor and a USB keyboard plugged into it, and most of the time the laptop itself stays closed.) Every now and then--mostly if the laptop has been asleep for a while, say, overnight or all day--it'll refuse to wake up. I've never had one of the kernel panics described in this thread: it just won't wake up, even if I open the laptop, until I unplug the external monitor from the monitor-out socket. Once I unplug the external, the onboard screen comes right on, and I can even re-attach the external monitor and it'll work just fine; but if I close the laptop, I'm back at Square 1 with a comatose computer.
Restarting the machine doesn't help. Tossing the PowerManagement.plist file solves the problem temporarily, but eventually it recurs. Anybody have any insights? Other things I might try? Similar experiences?

Try Ejecting the External HD before sleeping the Mac.
Then see if the Mac Mini will wake and re-mount the External HD.

Apparently, my company email that I have on my ipad prevents me from manually backing up to icloud. Does this mean that icloud is being blocked entirely from my ipad?

If my company email on my ipad blocks me from manually backing up to icloud, does this mean that icloud is being blocked from my ipad completely?

I'm not sure if they can completely block iCloud if you have your own Apple ID. I assume that they just don't want their data backed up to Apple's cloud.
But the more important point in this whole discussion is would the company be honked off at you for doing something on the iPad that they do not approve of.

Hello everyone,
Does anyone know how to prevent the imac from going to sleep when using the restore disk to start the system. This is the state I need the imac in to create the requited backup before I whipe the system and do a clean install of Mountain Lion to resolve all my issues. I have many system issues that started with upgrsade to snow leopard got worse with uprade from mobileme to icloud, and continue to pleague me with the latest upgrade to Mountan Lion.

Thanks, but these options are not available from the restore disk startup. I am usinig the diskutility on the restore disk to create the clone of my had drive. I think that the caffeinate command is working, but I am not able to run the diskutility from that terminal window.

School iPad - Prevent student from sending PDF in iBooks

I am desperate to disable the option of sending PDF files from inside our Student's iPad device.
We badly need to prevent our cadets from sending our Aviation Charts & documents (that we developed in PDF format) to external entities.
If only there is an option in the restriction menu to disable such option. The thing is every student has their school gmail account in their iPad.
These security issue really poses a big threat to our iPad implementation.
Hoping for such feature to be available in the future specially for companies and school like us.

if this is a feature you would like to see implemented then you need to let Apple know as these are user-to-user forums that Apple does not monitor. http://www.apple.com/feedback/

I'm not terribly concerned with "ExternalMedia" as that always appeared in Mountain Lion as well but never actually prevented my system from putting the monitor to sleep. My concern is with the "UserIsActive" item as it appears to refer to "MAGICWAKE" (a google search only shows an app that I do not have installed and sheds no light on what it means in this context) and points directly to my keyboard and trackpad. Oddly, turning "Allow Bluetooth devices to wake this computer" in the Bluetooth advanced preferences does not change this, nor does rebooting. The countdown that appears here is always in the 1160 to 1195 range. I'm completly stumped...

I have the same problem, but i cannot solve yet.
I have to wait almost 2 minutes for sleep mode when i close the screen
If i click sleep in the main menu is the same problem.

After printing 'hpdot4d' process prevents computer from sleeping

Hi,
I noticed that after printing a document that the process named 'hpdot4d' continually writes something as seen in fs_usage preventing the computer from going to sleep. The computer sleeps fine before printing and won't sleep after printing. If I kill the process the computer will sleep again on it's own. I am using an HP Photosmart 8250 with the Mac Pro.
This is what shows up continuously in fs_usage after printing a document.
21:01:45.042 select S=0 0.100020 W hpdot4d
21:01:45.116 write F=2 B=0x65 0.000009 hpdot4d
21:01:45.116 write F=2 B=0x75 0.000002 hpdot4d
21:01:45.116 write F=2 B=0x65 0.000002 hpdot4d
21:01:45.116 write F=2 B=0x75 0.000002 hpdot4d
21:01:45.116 write F=2 B=0x65 0.000002 hpdot4d
Anyone else have this problem? Where can I make Apple aware of this if this is a bug that can be fixed? As far as I remember this wasn't a problem in Tiger.
Thanks.

For what it's worth, I've had that hpdot4d process showing up ever since I set up my HP officejet 5610 on my Mac, and I'm still running 10.4. I'm pretty sure this is an HP problem, not an Apple problem...
