OS X :: Macbook Pro Will Not Shutdown / Turn Off
Apr 28, 2008
I have a 15.4 in macbook pro, intel core 2 duo 2.2 GHz 2 Gb RAM 120 GB HD and I bought it almost a year ago. I purchased leopard for Christmas and installed it. I also bought a western digital 500 gb mybook to use with time machine. Since around that time, my computer sporadically will refuse to turn off. Everything will run as if it is going to turn off, and then the screen goes blank and the computer stalls and will not shut off. The num lock and caps lock keys do not light up by my lap fan keeps running. To turn it off I have to hold down the power button for five seconds. I already brought my laptop to the apple store and they sent it to wherever and it still has been doing this. I also ran a series of hardware resets that the tech line gave me.

I was watching a movie on my iMac and this box popped up telling me to hard shutdown and restart my computer. Now I can't get it to turn on. When I press power it makes the start noise but the screen stays white. The apple doesn't pop up and it won't load. Trying to put in disks that came with my computer don't seem to work either.

if this kind topic has been discussed before, i just have no time to check.
So i need your help ASAP.So yes i have bootcamp'ed my macbook to windows 7 34bit.
And i think i made a mistake during installing it.Well when given the partition, it was 4 partitions , i chose bootcamp partition, but unfortunately it cant be installed on it, so i tried to format the bootcamp partition, and it's ok, so i have done it.But the problem is, i couldn't get into the mac whenever i restart or shutdown and turn on back.

When ever I turn off my iMac (AL mid-2007 running 10.5) it seems like it hangs during shutdown. It takes about 60 seconds to shutdown and after about 30 seconds it starts to show. It looks like this, except it still shows my wallpaper... (This is just an image I found on the web). I am not sure why it is taking so long to shutdown lately... I don't remember it taking nearly this long in the past. Here is a photo of everything that is running during shutdown and it still does it. (I usually try to close out of apps before shutting down).

My system has randomly shut down twice now in the last two days. Dual G5 2.3. I checked the console log, which I know very little about, and it said this:
localhost kernel[0]: ApplePMU::PMU forced shutdown, cause = -122
Two questions-
what's the -122 code mean?
Do you think resetting the PMU would be the solution to this?

I have a problem with my 17'' MBP unibody:
1) Bluetooth is ON:
I can't turn it off. The checkbox is inactive.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.

I've been reading about this overheating/core shutdown problem. How would I know if I'm experiencing a core shutdown? What happens?

I have a MBA, and I do notice, more often than I had expected, that I'm experiencing core shutdown. I do agree with a previous post that it could, at least partially, be related to the video card/driver. If I decide to run a YouTube video while having Outlook open in VMWare Fusion, I'll usually shutdown a core. Other combinations of applications can do it too, but this combo is almost guaranteed.
My question is: Is there a time where core shutdown is good, for example, to preserve the integrity of the hardware? I don't want to go into the Genius bar complaining if all they're going to say is "Well look what you're running! Of course it'll shutdown!"

So I have a MBP C2D from early 2007 that up until recently has been running fine. The battery died long ago, so I keep it plugged into the wall which was fine until yesterday. What started happening is my MBP would shut off completely (as if the battery died) and then when I try starting it back up, it would randomly shut off at some point during the boot process (not at one specific point; sometimes it barely makes it into OSX and other times it does not).
Anyone know what could be the problem? I have not installed anything new or changed any settings that could effect the system. To me it feels like the AC Adapter isn't giving the machine enough power, but I don't know for sure.

i am unable to shutdown my MAC normally. I always have to force shutdown. The issue has started after one of the framework update. Now-a-days even the processors heats up very quickly.

i was wondering what the general consensus was for turning wifi on and off. i normally shut down my MBP during the night, and turn my wifi off as well.
is it worth to turn the wifi off at all, or can i just leave it on? Â
the reason i ask is because it would be nice to just power on and have it set up without taking the extra (5 seconds) to turn it on.

Had (used) iBook G4 several months now & thoroughly enjoy it, even tho' I live in the sticks where there's no hi-speed/wireless available; I connect to internet & power, which is fine.
This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.

i am a teacher in a school where we have been told that every student must shut down each MacBook or iMac when finished. It is not unusual for 6-8 classes a day to do this. I have said putting the MacBooks to sleep would be better for them. Some of the laptops are taking 5 minutes to restart. Can't find data from Apple to support my concerns.

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?

I think I am getting the well publicized core shutdown with my MBA but I can't be sure. I will be doing a task and things like expose will be as smooth as can be but then all of a sudden it slows to a complete halt, everything lags, expose is jerky, cmd+tab takes ages to switch application and keystrokes such as typing take seconds to appear. For a good 5+ mins the computer becomes totally useless. Is this what a core shutdown does to the computer? Is there an application I can use to monitor how many cores are running? I looked in the activity monitor but couldn't find information about how many cores are running. I have used smc control to monitor my cpu temp and I sometimes turn the exhaust up to max rpm before I watch a video or do something that has been causing the core shutdown (if thats what it is) in an attempt to try and keep the cpu cooler.
I have read about coolbook but I don't fancy paying for an application to stop a fault that shouldn't be happening. Are Apple fixing these faults? Is this a problem with ALL MacBook Airs? I ask this because there seem to be two groups of people. People that don't experience this (or say they don't, maybe don't want to admit a fault with there new shiny toy?) and people who have had 3-4 machines all with the same problem. I would love to know if this is indeed a core shutdown fault and if Apple replace it for me as it is becoming increasingly frustrating and not acceptable for a $1200 computer. Would also like to hear from people that have had the core shutdown fault fixed or replaced from Apple and if it has fixed the problem, or if it still exists.

It's been happening for a while now and I had hoped 10.5.3 would fix. When I choose to restart or shutdown, 90% of the time it hangs on grey screen after logging out and I have to hold down power button to shutdown. No apps hanging. Also have problem where when I open the cover to bring my MBA out of standby mode, I'll be presented with the logon screen. I'll type my password and my screen goes blank like it's gone back to sleep but the power light is fully lit. Have to close cover, wait till it goes on standby, then open cover to bring up password logon again. Should I reinstall OS X again?
