MBP hanging on shut down

If anyone can help me with this, it would be most appreciated. Each night when I shut down my MBP, it goes through the normal shut down procedure, but then gets stuck on the spinning shut down clock and I have to do a forced shut off.
Someone in another thread suggested the computer was searching for a attached external HD that didn't have time to unmount, but I manually unmounted all attached drives before turning off the MBP.
It can't be good to do a force shut down every night, so I hope someone can help me with this one.
Thanks,
Ron

Nope, no new ram... everything is from the factory.
I suppose I could force shut down every night, but I'm used to pressing the off button and going to sleep. These days I've been waiting for it to shut down (it shuts down normally about 20% of the time).
Thanks.

IMac 21,5": Hangs or shuts down

Hello all!
My iMac 21,5" hangs or shuts down once in a while.
It also gets really slow, especially when saving a file in Adobe Illustrator CS6 and than switching to the finder.
I hope somebody can help me.
Many thanks.

That panic was not caused by third-party software. If the problem is recurrent, the possibilities are:
A stale or corrupt kernel cache
A damaged OS X installation
A fault in a peripheral device, if any
Corrupt non-volatile memory (NVRAM)
An internal hardware fault (including incompatible memory)
An obscure bug in OS X
You may already have ruled out some of these.
Rule out #1 by booting in safe mode and then rebooting as usual. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
You can rule out #2 and #3 by reinstalling the OS and testing with non-essential peripherals disconnected and aftermarket expansion cards removed, if applicable. Sometimes a clean reinstallation (after erasing the startup volume) may solve a problem that isn't solved by reinstalling in place, without erasing.
Corrupt NVRAM, which rarely causes panics, can be ruled out by resetting it.
If your model has user-replaceable memory, and you've upgraded the memory modules, reinstall the original memory and see whether there's any improvement. Be careful not to touch the gold contacts. Clean them with a mild solvent such as rubbing alcohol. Aftermarket memory must exactly match the technical specifications for your model.
The Apple Hardware Test or Apple Diagnostics, though generally unreliable, will sometimes detect a fault. A negative test can't be depended on. Run the extended version of the test.
In the category of obscure bugs, reports suggest that FileVault may trigger kernel traps under some unknown conditions. Most, though not all, of these reports seem to involve booting from an aftermarket SSD. If those conditions apply to you, try deactivating FileVault.
Connecting more than one display is another reported trigger for OS X bugs.
If your system is not fully up to date, running Software Update might get you a bug fix.
In rare cases, a malformed network packet from a defective router or other network device can cause panics. Such packets could also be sent deliberately by a skillful attacker. This possibility is something to consider if you run a public server that might be the target of such an attack.
If none of the above applies, make a "Genius" appointment at an Apple Store to have the machine tested. You may have to leave it there for several days. There isn't much point in doing this unless you can reproduce the panic, or if you can't, it happens often enough that it's likely to be repeated at the store. Otherwise you may be told that nothing is wrong.
Print the first page of the panic report and bring it with you.
Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you know how to restore, and you have at least two independent backups.) Don’t erase the recovery partition, if present.

MBP tries to shut down after 30 minutes of inactivity

Hello,
After 30 minutes of inactivity my MBP attempts to shut down. An open app, like Safari, will prevent the shut down process from completing. This has been going on for a year and I have not found any way to prevent it. I have tried resetting PRAM, looked in System preferences, updated OS with every dot release and have not been successful.
Any ideas on possible causes and ways to prevent this are greatly appreciated.
Thanks,
Karl

Hi nachdenki,
I have checked System Preferences/Energy Saver. Please note that my MBP attempts to shut down completely (vs. going into sleep mode.) My sleep settings are for a time period that is shorter than the 30 minutes of inactivity that is associated with the shut-down. Is there a setting in Energy Saver that affects an automatic shut-down that I may have overlooked?
Thanks,
Karl

MBP fails to shut down

Lately my MBP fails to shut down. I quit all apps and then click shut down, the dock and menu bar go away just leaving the apple desktop and the mouse (turns to the beach ball after a while). Last week I wiped my computer and started from scratch hoping it would fix the problem but it didn't. I have repaired permissions and reset the PRAM and have taken out the battery and held the power button for five seconds to reset something else (i forget what it is called). I am thinking this has something to do with time machine and my time capsule. Sometimes time machine will attempt to backup, but will sit at preparing for hours without ever mounting the image. I try to stop it but it wont stop and at that point I can't shut down. Isn't time machine supposed to stop when I shut down? Even if i force quit the backupdb process in activity monitor, my computer will not shut down. So as far as I can tell, time machine is doing something to prevent shutdown or something is but it is really getting annoying. Any help is appreciated.

Check your console log using the Console application and look around about your shut down time. Look for information about a process that did not shut down. Usually shutdown problems occur because an application you are using does not completely shut down or stops responding.
Does the computer shut down normally if you don't run any applications? Have you tried creating a new user account, then logging into that account instead of your normal account? Does the computer now shut down normally? Have you tried booting into safe mode to see if the computer will shut down normally?

Satellite 2710XDVD hangs at shut down

My Satellite 2710XDVD hangs at shut down, showing the 'Windows is shutting down' screen. I am running Windows 98 SE, bios 7.60. The problem started after installing a Sitecom WL-011v2 card.
When I remove the card (actually, disable it using the control panel pc card manager) Windows shuts down normally. Sitecom says it is a bios problem.
Does anyone have a solution?

I came to the conclusion that the problem is that the PC card is not shut down properly when Windows wants to shut down.
My solution is to disable the PC card when I want to shut down Windows. I made a script using AutoIt v3 to do this, just click on the script and it will disable the PC card and then shut down Windows properly.

Hang at Shut Down... When exactly are drives safely unmounted?

My Mac often hangs at shut down (like many others). I typically get all icons, dock, and menu bar removed and am left with the desktop picture, or sometimes I'll get to the blue screen (after the desktop picture has gone) and get the circle made of straight lines that just continually loop.
My question is: Have the drives unmounted and therefore aren't potentially damaged due to the power being forcefully cut off (holding the power button), or are they still mounted and therefore possibly damaged requiring (to be safe) another round of DiskWarrior magic?
I'm getting tired of spending all of my time running DiskWarrior. Are these fixes necessary?
any thoughts are welcome and appreciated!

Hi! I'd be concerned because the last command that the OS gives at shutdown is for the drive heads to "park" after which the power to them is turned off. If they are not "parking" the heads properly it could cause problems. I'd investigate unhooking the external attached devices to see if any of them are hanging the shutdown but also if you have several volumes or drives attached to the computer if often takes a seemingly long time for the OS to complete the disk chores at shutdown. Have you waited at least 5 min+ to see if it will shutdown? Also if Diskwarrior shows anything in "RED" then the directories definitely are having problems and should be corrected. Often a directory will suffer damage but continue to mount and function until the corruption finally gets so bad it crashes. Regular use of DW usually keeps them in good shape. Tom

IMac hangs at shut down

Hello, maybe someone know what could be with my iMac 21.5-inch: 3.06GHz Intel Core i3,(OS X 10.6.6) Everything was working fine for about a couple weeks, but now it hangs at shut down. I left for a bit thinking it would eventually shut down, but came back an hour later to find it still spinning on the grey screen,I left during the night, but nothing has changed still spinning on the grey screen. The only way to shut it down was to hold the power button.
Does anyone have any suggestions?
Thanks!

I don't know if you have managed to resolve this yet? Have you found posts like this one;
https://discussions.apple.com/thread/2784084?start=0&tstart=0
Like the person posting in that thread I have found that doing a disk repair has fixed the problem that was preventing my 2011 imac from shutting down.
To do the disk repair hold down the md and R keys whilst the machine is booting. You should find yourself in the utilities app with an option at the bottom to run the disk utility and from there you can run a repair on your boot disk.

MBP won't shut down

Hi eveyone,
I hve a MBP i7 with 8Gb Ram that won't shut down, it just hangs with the greyed cirlcle in the middle of the screen.
I have even left it on overnight and it still won't shut down unless i hold down the power key.
I have run Disk utility and Still no joy.
Any ideas what else i could try?
Thanks in advance
Steve

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the page that opens.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.

MBP (Mid-2012) Shuts Down While Attempting to Start Up (HardDrive I/O Error)

Hey guys,
I've been having some issues with my mid-2012 MBP (8 GB's RAM, 750 GB HardDrive). It has the latest version of OS X Yosemite installed.
About a month ago, I turned on my MBP, typed in my password and it began loading the operating system. This usually take 30-45 seconds or so for the loading bar to fill up and the desktop to show. And then maybe another minute or two once the desktop is visible for the "startup process" to finish in the background so I can open apps quickly and efficiently.
However, this time, the Macbook took about 10 minutes, got halfway done and I was forced to give it a hard shutdown. I then tried unsuccessfully to start the system again and each time it wouldn't load past a certain point. It then miraculously started working after letting it cool for a few hours.
Fast fwd a month later, my computer seemed much slower than usual. I always was checking activity monitor and my file cache was taking up 4gb of ram at times. My computer would slow down to the point where I had to give it a hard restart often.
Then last week, I started the computer, typed in my password and it started to load. After a minute of trying to load, it shuts off. It no longer loads to the desktop, it simply shuts down after every attempt. So I ran some diagnostics.
While doing the Single-User Mode...it spit back out that I have a HardDrive I/O Error. Also, my hard drive is not mounted when I run disk utility.
All my files are backup online and on external HD. Do you think I need a new internal hard drive? Suggestions?

A hard drive I/O error means that the hard drive is completely damaged and cannot be used anymore, so you need a new hard drive. As you have a backup, you will not lose any data.
It is up to you to replace the hard drive yourself or to take the MacBook to an Apple Store or reseller. The price difference is not very high, but if you do it yourself, you can choose the hard drive you want to install (7200 rpm hard drives will give you a bit more performance). If you have decided to do this yourself, buy the hard drive at OWC or Crucial.
After getting the new hard drive, use OS X Recovery (hold Command, Alt and R keys while your Mac is starting up) to restore the backup.

MBP will not shut down, also F keys etc. not working. Help?

Hello, must preface that I am not a very computer-savvy person, so please explain as if to a four-year old.
My MBP is about 4 years old, but has been working great all that time. Suddenly, a problem.
I realized that most of my F keys have ceased working, such as turning on the backlit keyboard, adjusting screen brightness, and adjusting volume. I thought a restart would fix it, but my machine will not restart or shut down. I click to request it, but nothing happens. I also try to view "about this mac" from the apple-icon menu (wanted to provide that info for this entry), but the spinning beach ball of doom appears for a moment, then vanishes, and the panel with the info does not open. Also, some of my hot corners have stopped working. Otherwise, it works fine. All my software works, and no sudden crashes.
I haven't installed any new software recently, or done anything out of the ordinary to the MBP, for a few months at least.
I haven't forcequitted the machine, tried to start in safe mode, or started while pushing command, R, P, option, or anything else. I did clear the caches and ran disk utility to repair permissions... then saw another post online saying I *shouldn't* do that stuff. Doh.
Does anyone have any suggestions on how to resolve this? Obviously, the machine is out of warranty, I do have the disks that came with the machine, and I run time machine regularly...but I'd rather not have to do a fresh reinstall of everything, if it can be avoided.
Any help would be much appreciated.

"I haven't forcequitted the machine, tried to start in safe mode, or started while pushing command, R, P, option, or anything else."
do command-option-p-r
if that does't do it reset the smc.

MBP 17inch A1151 shuts down with battery

I just bought a used MBP. It came without a batter. It booted fine when I bought it and ran off of my MacBook power adapter (60w). I ordered a new battery and 85w charger. Whenever I put the battery in with it started up, the MBP shuts down within 5 seconds. If I put the battery in when it is off and boot it up, it will not get through the boot process without shutting down. I left the battery in with the MBP off and plugged in to charge the battery. It is fully charged.
I have seen reports of this problem and wonder if it needs a new logic board or could it be something else.
Or, if I should just use it without the battery as a desktop computer.

I saw that some people were posting battery reports, so I checked mine. I booted it without the battery and opened the Power information to see the battery cycle count, etc. So, i installed the battery and the battery indicator in the menu changed from X battery to plugged battery, said it is at 96% and charged, but the system info never changed from no battery installed. I even went to printers and then back to power and it never noted a battery was installed. weird.

Windows7 hanging when shutting down applying updates

Whenever I shut down or reboot Windows7 I get a message that Windows is applying update 9 of 13, but the "update" never gets "applied" and Windows7 just hangs supposedly trying to apply it. Yet when I subsequently boot into Windows7
and look a Windows Update there are no important updates available, much less being applied.
Something is messed up. How do I fix this problem so that Windows7 does not attempt to apply a mythical 9 of 13 update, which does not exist, when I shut down, and hang my Windows& shutdown or reboot

Download appropriate system readiness tool and run it
http://support.microsoft.com/kB/947821
If the updates that are failing to install are dot net based then you may need to run dot net repair tool.
https://www.microsoft.com/en-ca/download/details.aspx?id=30135
Note this is not recommended but is an option:
If you are having problem with single update for example you may right click (in windows updates screen) on it and chose to hide it.
This way at least you will allow other updates to install properly.
