Mac Pro 2008 keeps shutting down and restarting

Just the other day after being shut down for a week my Mac Pro 2008 started shutting down and restarting on its own. Any idea where to begin troubleshooting?

Then they are probably completely clogged with deleted data.

My Macbook Pro won't shut down or restart without forcing shut down. Hangs on grey screen. iTunes not recognizing iPod.

HELP!!!
Here are the specs of my machine:
2011 13.3" MacBook Pro
4 GB Ram/320 GB HD
For the past several months my MacBook Pro refuses to shut down or restart without holding down the power button. Whenever I choose to restart or shut down the computer, it will hang on a grey screen. I have even tried letting it hang for an hour, and it still won't shut down. I notice that once in a while it will retart or shut down correctly if I had not used opened iTunes since turning it on. However, even manually closing iTunes before shutting down or restarting does not solve the problem. It seems as though it only shuts down if iTunes was not used since restarting the computer. Is this a registry error? Do I need to reinstall iTunes? I noticed this problem began happening after I uninstalled Kaspersky Virus Scanner, could that be the problem as well? Also, I cannot guarantee that the problem is only associated with iTunes. I just noticed that one of the few times it shut down or restarted correctly, iTunes coincidentally had not been used. Also, this problem started happening while I was still using Lion and has continued despite upgrading to Mountain Lion.
Also, whenever I update my iPod through iTunes, it won't eject properly, and a transparent icon of the iPod displays on the screen even after I have removed it from the USB port. Furthermore, the iPod will only be recognized by iTunes and will only be updated the first time I plug it in. After removing it and plugging it back in, it won't recognize or update the device unless I shut down and restart the computer. I have the latest addition of iTunes. I also have two iPods, one 80 GB Classic, and one 8 GB Nano, and I have the same problem with both.
I have AppleCare. Should I take my macbook to the genius bar?
Applications I normally use are Word, Safari, FireFox, iTunes, FinalDraft, Photo Booth, Notes, Mail, App Store, etc. No real heavy lifting.
Any feedback would be very much appreciated. :-)
Thank you everyone!!

I have this question too.

Macbook Pro won't shut down or restart under Lion.

After installing Lion, my i5 Macbook Pro will not shut down or restart. The shutdown starts and then hag=ngs with a grey screen and a spinning process indicator. Thoughts?

Mine too. Restart and shutdown do longer works. Have to hard crash it each time.
Called Apple, they have no clue.
Buy a PC. At least Microsoft admit problems and offer solutions.

Mac Pro won't shut down reliably

I have an early 2009 Mac Pro and after upgrade to Lion I have problems with shutting it down. I have checked other discussions, my symptoms are little bit different than most I saw (it does not stay in the grey screen with spinning wheel):
- sometimes it will shut down normally (although it may take long time)
- in most cases it will start shutting down normally, goes to the gray screen, then to the black screen, I hear disks are powered down, only think I hear is the power fan which is still running - and it stays like that for hour or more without any change - untill I hold down the power button for a couple of seconds
The behaviour is the same when restarting.
I have already switched off the "recent items" in System preferences/General and when swithing off/restarting I do uncheck the "reopen windows..."
I have Windows 7 in Bootcamp on separate hard-disk and I do not have any similar issues when shutting down or restarting from Windows
Everything is up to date and the only HW which is added to the Mac is internal USB hub card (was added befor Lion upgrade and there were no issues with it). This is the only problem I am having - everything else works, the system is stable etc.
I have already tried to repair disk permissions, but there was no problem there either.
Many thanks for any help. Tomas

Many thanks, that worked - I unplugged everything from the USB hub and it switched off normally. Then I tried to put stuff back and it looks it was the mouse which was causing the problems - although I find it hard to understand why Thanks again for your help, Tom

Mac Pro won't shut down

I'm helping a friend with her new Mac Pro quad (latest model, 6g RAM, 1TB OEM drive, 2 extra 1TB Seagate Enterprise drives installed for storage, 24" ACD) and she can't shut it down now. Worked fine for the last week since she bought it all but now it won't. I've had her do all of the usual things like Permissions Repair and such, but still the problem exists. All software updates have been performed, everything works fine except for the shut down routine. There's not much software on the box, Photoshop CS4 and Bridge, and that's about it, other than the OEM Apple stuff. The Adobe apps have current updates, too.
Any ideas?

try restarting with the command-option-p-r keys held down. Failing that, shut it down hard, then unplug everything...power..usb firewire...everything. Let it sit for 5min (that's prob longer than needed) and then restart. Failing that, call Apple tech support.

My Mac Pro won't shut down properly

I recently got a 2010 2.8ghz quad-core Mac Pro. It has Mountain Lion installed (10.8.2). For some reason, when I try to shut down, it seems like it shuts down with the display turning off and the fans audibly stopping, but the light on the front of the Mac Pro stays on with a continuous, non-pulsing glow. During this time, the Mac is essentially unresponsive. Pushing the button does nothing. The only option is to hold down the power button until the machine shuts down completely. I tried searching for this problem, but all the other threads are in regard to situations where the spinning wheel keeps spinning indefinitely. This is different because the wheel spins, then the computer seems to shut down except for the light staying on. It goes to sleep just fine. I tried resetting the PRAM with no luck. Any suggestions?

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 icon grid.
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.
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 entire contents of 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.

Macbook Pro won't shut down or restart because of Finder

I have a MacBook Pro (Retina, 15-inch, Late 2013). Recently, I tried to shut it down, but couldn't. I closed all running apps, then clicked on shut down, but nothing happened except the menu bar on the top of the screen vanished, but the dock was still there. I hit Command+Tab to check which apps were running, and it showed only Finder. When I right clicked on Finder it said Application not Responding. There was a relaunch option as well and I clicked it but nothing happened. How can I fix this? I have to force shutdown it every time. Though I am still able to put it to sleep.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Macbook Pro won't shut down or restart. Seems to be a permissions problem related to ipodupdater (whatever that is)?

Press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly to restart.

As soon as video touches my Source or Program windows the Mac Pro (3,1) shuts down

Linc,
You keep showing up when I search for this problem so I hope you can help.
I'm having the same issue in Premiere and Media Encoder (but not After Effects). My Mac just restarts itself as soon as video is loaded. I can start Premiere and open a project and go through relinking media, but as soon as video touches my Source or Program windows the Mac Pro (3,1) shuts down.
I've fixed the problem temporarily two times. The first time I was troubleshooting what was wrong and wound up putting in my old video card and after that fixed the problem, I switched back to my GTX 680. I also did a driver update. After doing that I was ok for a few days so I figured it was a driver thing or maybe the card just needed to be reseated. Then when it started acting up again I figured something was going on.
So I started searching again and came across one of your posts that recommended removing CUDA. I did that and it worked perfectly for a week until about 20 minutes ago. Crashed in the middle of an edit and now each time I restart Premiere it crashes as soon as video touches my monitors.
I found this post because I specifically searched for "com.nvidia.web.NVDAResmanWeb(8.2.7)" from my Problem Report.
Any thoughts?
Thanks,
Darren

Thanks for the reply. Sorry for the shortened log. Here's the full thing. By the way, where do you learn to read these things? Are there keywords like "error" that you just learn to look for or is it something for in depth?

Itunes make my mac pro impossible to shut down...

Hello,
So, when i launch itunes, my mac pro can't shut down. I choose "shut down", then the gray screnn and the wheel turning, but... nothing else. I have to shut it down with the button...
Mac pro nehalem 2010 with Lion or Mountain, after re-installing lion or mountain Combo, or re-installing iTunes, with or without any peripherics pluged (usb firewire...) with another sessions... Hardware test is all correct.
When i don't launch itunes, my session and my mac can shut down normally...
Excuse my english and thanks at all !

Mac Pro will not shut down

As the subject line says, my "early 2008" Mac Pro will not shut down. I have let it set overnight and it will not shut down or restart. I also installed an update which required a restart, selected to restart and the computer would not. Also, whenever I boot up, the computer hangs and will not load the finder. I have to do a "hard" restart and after a couple tries it eventually works...should I just call Apple?

Forced shutdowns tend to cause more directory errors.
How many drives?
Any green version?
Did you disable "allow disks to spindown"?
Possible it is an external USB printer or device, or cable?
I'd boot from another hard drive and do system repair and maintenance.
Create another boot volume if need be.
Startup with using Disk utility but also Disk Warrior.
And when it is working, make backups with CCC or SuperDuper.
Lacking that, boot from OS X DVD and go to Utility menu and access Disk Utility.

My macbook pro won't shut down, restart or log off

it's a month old. was behaving fine until about a week ago when it wouldn't shut down because itunes kept restarting itself whenever i quit. realised it was because of my alarm clock widget, which i've now removed. so the itunes is sorted, BUT, my mac still won't shut down.
what can i do? someone told me to download onyx but i haven't a clue what to do with it?

Don't upgrade to Snow Leopard in the hope that it will eliminate any preexisting problems on your MBP — it almost certainly won't, and you may have other problems as well (e.g., incompatible applications and startup items). Solve the problem first, then perform the upgrade.
If you Safe Boot the computer, will it shut down normally afterward? If so, disable all third-party startup items (System Preferences > Accounts > select your account and click the Startup Items tab), boot normally, and test again. If you can still shut down normally, one of the startup items is at fault. Re-enable them one at a time, testing after each addition, until you determine which one is causing the problem.
There are also applications that can run in the background and don't show up in the Force Quit dialog box — but they do appear in Activity Monitor when you instruct it to list Active Processes. Some can interfere with shutdown by refusing to quit when the Shut Down command is given. If the suggestion in the preceding paragraph yields no progress, let us know what processes are active on your computer when no applications are shown in the Force Quit dialog box.

My mac pro will not shut down

I'm using the lates OS X 10.6.8
Everytime i try to shut down my screen goes blue and wheel turns but nothing happens. I need to press the power button to get the Mac Pro to completely shut down, which can't be healthy for my mac?

Boot in safe mode and see whether the same thing happens.
Mac OS X: Starting up in Safe Mode
