Mac Pro sometime hangs on shutdown

Hi everyone,
I have a brand new Mac Pro. The only issue I have now and then is the system will hang when I go to shutdown, requiring me to hold the power button in for the 3 secs. Is anyone else experiencing this issue? I thought that maybe VirusBarrier X4 was the issue, but I have since removed it and I still experience this at times.
Thanks,
Tony

Any time you force or interrupt shutdown, which is when files are written to disk, directory is being updated, and the old and new volume information tables are written... you really need to either do a fsck on next startup; do a Safe boot to insure that the system does a check; or, option boot to your repair/emergency system drive.
It can take a minute. And the fewer of those background programs the better - like VB 4 - which may or may not be compatible (and sometimes just because it works with a bare test system of Apple software doesn't mean it works when other processes are present).
Try repairing the drive with your DVD or single user mode and running fsck. Then with Disk Warrior 4. And delete the caches and verify or files.
I don't know of any USB or FW device that will cause a system to hang on shutdown, but that doesn't mean there isn't.

Mac pro still hangs on the blue screen on start up.

Hi.
my mac pro still hangs for ages on the blue screen before the login page where i input my password appears.
i've tried starting up in command-V and that didn't work.
i thought snow leopard was meant to improve, it has just slowed my start up down greatly!
could someone please advise on how to fix this?
thanks
Dan.

Hi boom,
Have you tried downloading and re-applying the latest Combo update?
If not, go to the apple download page, find the Combo update (couple of hundred MB) and install it.
This has fixed various issues in the past for numerous users... it might do the trick for you.
After it's installed and rebooted, repair permissions and reboot again.
Also check to see (using software update) if there are no firmware updates available for you.
And, make sure the OS drive's root is clean, just the basic Applications, Library, System and Users folders, no other mess. If there are 'Previous System' folders from earlier Archive & Install situations you might want to remove those.
Finally, if you upgraded from a PowerPC to Intel using the Migration Assistant the symptoms you are describing are very common, the migration assistant well... it ***** :/

My Mac Pro is hanging after installing Mountain Lion

My Mac Pro is hanging and it started not long after I installed Mountain Lion. It seems to be related to Contacts in that it is constantly trying to sync with iCloud. It becomes unresponsive and when I force quit, other apps start going down. Eventually Mail hangs and I have to hit the power button and force a restart of the Mac Pro. It also brings down my DSL connection which runs through an Airport Extreme. Has anybody had similar experiences? Contrary to what it might say in my profile, I'm running a 2.8 Ghz Quad Core Mac Pro and 10.8.2.

Welcome. If you search for "Mountain Lion freeze" you will see you are NOT alone. But as far as I know there is no solution.

Mac Pro restart hangs

Mac Pro running Tiger. Recently began hanging on restart - will shut down and turn on fine; however, choosing restart from the shut down menu or restarting after software upgrades causes the machine to close down apps and display, but machine never completely turns off. After it hangs I force a power off and everything boots up normally. No error messages on reboot. Any ideas?

It probably won't happen on a Safe Boot.
It probably isn't related to the problems with the Radeon X1900 and heat and dust build-up.
It could be your drives need directory maintenance with Disk Warrior. At shutdown it syncs and updates the backup volume information table, the journal, as well as writing out any changes not saved to disk and still in memory (and you have 16GB).
Cloning the system is always a good idea to do from time to time, followed by reformat and restore (after you run Disk Utility and Disk Warrior on the new clone).
Sometimes reapplying the combo update helps, other times an Archive & Install.
Soft read and write errors.
You shouldn't need to reinstall. And as long as you keep backups and use SuperDuper you can have a working clone and either use the newly cloned drive or restore back to your boot drive.
Formatting a drive (Partition and set new volumes, not erase) insures that the first and last disk sectors are safe for writing (you can't test or map out bad blocks in the partition tables once created).
Corrupt cache files can also cause trouble which is why SuperDuper skips copying those and lets the system create fresh when first booted.
The worst error is if the journal is corrupt. Turn off journaling, repair the drive, then re-enable journaling, all while booted from your backup/emergency drive.
Having a working backup clone and an emergency boot drive are things I consider essential, using SuperDuper (personal favorite) along with Disk Warrior.
A bad USB cable or USB hub, or some external device can cause a system to hang or not shutdown or restart in timely fashion.

How do I prevent my Mac Pro from hanging up in a start/stop loop?

My Mac Pro has a strange behavior I need help with. This computer is used almost exclusively for audio recording in my studio. I run Cubase 4 as my primary sequencing software. Everything will be going fine during a session, and then the software will abruptly hang up in a *start/stop loop*, stuttering back and forth between these two functions for up to 2 minutes before stopping. During this loop problem, the start/stop transport buttons alternately light up and the song starts and stops. Nothing I have tried will interrupt the problem. It just runs its course and then stops, usually between 30 - 90 seconds.
Interestingly, the same behavior shows up in other applications and in the Finder. In Quicktime and iTunes, it shows up as a start/stop loop. In the finder, it will shuttle back and forth between two related functions and beep each time. In word, it will show up as a key stick, typing the same letter over and over.
Needless to say, this is all very frustrating and embarrassing when clients are here. Any help will be greatly appreciates. Let me know if you have any additional questions.

I'd begin with repairing your drives with Disk Utility and Disk Warrior; clone your system to another drive, and check for corrupt files and prefs.

Mac pro sometimes taking about 10 minutes to boot up..

hey there.. my mac pro has recently started taking a long time to boot up..
i use split screen and the other screen just goes a plain blue colour until i have to hold the on/off button on the tower until it goes off and then turn it back on again..
when it comes back on the icons are still there but they remain frozen for about 10 minutes..
i was just wondering how to tell if i need more memory or anything..
any help would be massivley appreciated thanks : )

I get exhausted with "how to prevent and repair system" advice, it all boils down to
Disk Warrior - #1 disk repair and maintenance to deal with the above, but a repair is sometimes only as good as to recover files, and you should always be ready to restore from a good backup.
SuperDuper - clone system, while it is good shape; clean install to another drive for emergency; more than one backup set
And your boot drive file system and directory are corrupted by hard power offs same as hard freeze.
Rule out why it takes so long, trial and error, remove cables, devices, insure that the Mac OS X drive volume is selected in Startup Disk control panel (sys prefernces) and that network booting is not by accident or otherwise selected.
Add more backup drives, a maintenance routine you follow, and try cloning your system to make sure yours works as it should - and so in an emergency you aren't doing it for first time.

My Mac Pro suddenly hang up and when i restart only can see a question mark file

Can somebody help me fix.. need it urgent. when i bought this last year there is no CD for installer or etc. now I having trouble in restoring at least the OS.

Your hard drive is likely damaged.
Boot into your Mountain Lion Recovery partition by holding down the command and R keys whilst booting. There will be a window that opens with four options. Choose Disk Utility, select your hard drive and tell Disk Utility to verify the volume. If it fails verification, try to repair. If it will not repair then your disk is likely dead. If it does repair or if no errors are found, try reinstalling the OS -> you won't lose any data this way.
If, however, Disk Utility reports that the drive cannot be repaired, then it's time to go shopping for a new drive.

Mac Pro 2013 fan speeds up to maximum after restart.

My brand new Mac Pro 2013, hanged on shutdown..
so I had to restart by using the button on the cylinder, when it restarted it sounded like a vacuum cleaner, the fan started to spin fast and didn't stop anymore and my mac was suddenly very slow :S.
After restarting the mac pro works fine again! this happened 2 times now...
Already called with apple they said that i should try and work with it and see if the problem comes back again.
Maybe any of you knows what could be wrong.??????

Improper shutdown Mac pro 3.1 (2008)

Hi, my mac pro does a Improper shutdown on games and shutdown on sleep mode. I have made all the reset (PRAM and SMC). I run on OS10.6.5. I have tried two different video cards (8800GT and HD 4870) same crash here. The apple hardware test find nothing. So now I'm thinking that it's probably the power supply.
Anyone have a idea to help me find out.
Thx

Erase the drive and install Snow Leopard on the 2008, then upgrade to Mavericks.

Mac Pro Firewire Problems

I use an external Firewire 800 drive for Time Machine and a MOTU 828 mkII Audio Interface (Firewire 400) on my new (refurb) Mac Pro. Everytime I shutdown, restart or sleep the Mac Pro, I lose Firewire connection to either the drive, the audio interface or both. Unplugging and replugging the firewire cables usually doesn't work and I'll have to restart the Mac until it recognizes the firewire devices. Regardless of what start-up procedure I use (firewire plugged in before or after), it's hit or miss. Usually once it's recognized, it's stable. Oddly, the firewire devices show up in System Profiler even if they aren't recognized elsewhere - desktop for the drive or Audio Midi Setup for the audio interface. On my old G5 with Tiger, the same drive and audio interface worked perfectly and I could turn them on or off at anytime and have them be instantly recognized.
I have seen posts about similar problems both here and on other boards. Has anyone got to the bottom of this problem? Is it my Mac Pro or is it a Leopard bug? Just curious before I make the call to Apple.

Sorry if I wasn't clear in my first post. I have the audio interface plugged into the rear firewire 400 port and the backup drive plugged into the rear firewire 800 port. No daisy-chaining involved and strictly just those two firewire devices. I'm going to do some testing with using the front ports and see if that makes a difference. Thanks.

Need advice re: Lightscribe drive that will work in Mac Pro

I have the stock superdrive in my Mac Pro upper slot. I had a three year old LaCie 16x Lightscribe Drive that I took from my G5 and installed it in the lower slot. I could not get the MacPro to recognize it. I triple checked the cable connects, tried Cable Select and Slave jumper settings, installed the latest LaCie system extensions for the drive, but it still will not recognize it. It does not show up in Disk Utility or anywhere else.
So.... I bought the Lite-On DH-20A4H08C drive from Amazon. Put it in (Cable Select) mode, and the Mac Pro recognized it right away. The problem is that the tray in the Lite-On drive sits too low in the chassis, and when ejecting, it catches on the drive door of the Mac Pro - sometimes it can get out all the way under it's own power, sometimes I have to pull it out. It retracts pretty much OK. I'm not into the stress that this misaligned drive is putting on components, so I plan to return it.
Can anyone recommend an IDE Lightscribe Drive that will work in the Mac Pro and where the tray will eject nicely through the seemingly slimmed drive doors on the Mac Pro? If not IDE, can I use a SATA Lightscribe Drive? I understand there are two SATA ports on the motherboard beneath the back of the optical drive enclosure.
Looking for some positive experiences here please?
thx -b

Well, I found the fix! I ditched the Lite-On and continued fiddling with my better fitting LaCie drive and I found that the LaCie drive has to be in the upper bay (i.e. first in the chain) for it to work. The SuperDrive had to be moved to the lower bay (last on the chain). I have no idea why this is, but swapping positions causes the LaCie drive to be invisible to the Mac Pro. Of course, both drives are set to Cable Select. Even LaCie tech support (which was very responsive BTW) were scratching their heads.

New Mac Pro and iMac as Display – Several Crashes

Hello,
I am using a new Mac Pro (late 2013, 3.5 6C) and are really happy with it. But I have one problem …
Currently I am using an iMac 27" as a display via Apple Thunderbolt cable (original cable from Apple).
But when I switch my displays via cmd+f2, my mac pro sometimes crashes. So I can switch back to my iMac always, without issues. But sometimes, when I want to switch back to my running Mac Pro (no screensaver etc.), I cannot switch back and the Mac Pro simply reboots.
Any ideas what to do? I've sent a bug report to Apple already …

The warranty entitles you to complimentary phone support for the first 90 days of ownership.
If you bought the product in the U.S. directly from Apple (not from a reseller), you have 14 days from the date of delivery in which to exchange or return it for a refund. In other countries, the return policy may be different. If you bought from a reseller, its return policy applies.

Mac Pro 5,1 hangs on shutdown

I use a 2012 3.33 GHz 6-core Mac Pro 5,1 in my recording studio, running OS 10.9.2 with 16 GB RAM. I use all of the PCIe slots: slot #1 is the ATI Radeon HD 5770 graphics card, #2 is a Universal Audio UAD-2 Quad card for my powered-plugin library, #3 is the Avid Pro Tools HD-Native card and #4 is an OWC Accelsior 120GB 6G SSD which I use as my primary Pro Tools production drive.
Ever since I upgraded to Mavericks and added the Accelsior SSD (this January) the computer hangs on shutdown and occasionally on startup. With shutdown it's the same every time - when I shut it down I get a blank gray screen with only the cursor arrow showing, and I can still move the arrow around. After a few minutes I hit the power button to force it to shut off.
The machine also runs very sluggishly and takes forever to boot up. It almost as if there are a ton of hidden processes bogging it down.
I've checked and re-checked for viruses, I've reset the SMC and PRAM, I use Disk Utility to verify all my drives and repair all the disk permissions about 3 times per week, and I do daily diagnostics with Tech Tool Pro 7. I'm about to pull all the PCIe cards except the graphics card and disconnect all peripherals except keyboard and mouse and then reconnect everything in steps but before I do all that I was wondering if any forum participants have dealt with a similar problem ?

You could try a different SSD than the Mercury model from OWC.
Also, any and even the ones from OWC should have TRIM enabled and you do not.
I have a number of Samsung SSD and just noticed one $110 250GB

Mac Pro hangs on authentication

I have a Mac Pro dual-dual 3GHz which has a sporadic issue where (as far as I can tell) processes hang when authentication is attempted.
I haven't seen any rhyme or reason to when this occurs. Sometimes, I will be in the middle of working, and I will notice that Terminal hangs when I try to open a new window. Other times, it will occur after the machine has gone to sleep (it wakes up fine, but then attempting to log in will hang).
When this issue is occurring, all the following will hang:
* Logging in via loginwindow
* Switching users
* Logging in via SSH
* Performing sudo
* Opening a new Terminal window
The problem doesn't always go away upon rebooting. Sometimes, I reboot and everything is normal; on other occasions, the login window will hang after I enter my username and password and click Log in, even after multiple reboots.
This problem has never occurred when rebooting in safe mode. However, often I can reboot in safe mode, log in, everything appears normal (for safe mode), but when I reboot in normal mode, the inability to authenticate occurs again.
When this problem is occurring, it occurs on all accounts.
Eventually, after enough reboots, I am able to log in and work normally (until the next time it happens).
Also, I have never noticed anything wrong with either CPU or memory usage when this problem is occurring.
On one occasion when this was happening, I happened to have an open root SSH session available. I ran sc_usage on securityd and found that it was waiting on 'machmsg_overwritetrap'. It waited over 5 minutes without anything further happening. I'm not sure what, if anything, this indicates. (Also, 'LASTPATHNAME_WAITEDFOR' was blank.)
Any ideas would be welcome.

Corupted object.... I had this under 10.3.x..... had to wipe clean and reload OS X from CD.
I read in a post that you could boot in safe mode, and delete "something" (I do not remember now) where the authentification data is stored and then you re-create your users... search past posts.
My suggestion of a clean reload is a safer bet that you will have a clean system.

Mac Pro crashing on shutdown (and some other things)

The following behavior began about 4 or 5 days ago...
Mac Pro crashes/freezes every time I shutdown (or Restart). Some process seems to be not quitting on shutdown - the screen goes blue and I get the spinning beachball. It'll just hang like that indefinitely. To get it to shut down, I have to hold the power button for several seconds. After starting up again, the machine *mostly* runs fine, but there are some apps/services that either just don't do anything, or causes the Mac to hang, or get into a funk state. These other things that seem to destabilize it include:
Apple menu > About this Mac: nothing happens (no dialog)
iTunes: dock icon just bounces, iTunes never launches
System Prefs > Accounts > Login items: System Prefs hangs. Force quit allows Prefs to open again.
Some apps/services also cause things to hang:
Activity Monitor: quitting some processes causes Actvity Monitor to freeze
Clicking SOHO Notes (tab alonmg the edge of the monitor) results in spinning beachball
Rolling over Linotype FontExplorer in the Dock causes the Dock to freeze, FontExporer never opens
There are probably other things that would make it hang, I have not gone looking for them all
System details:
Mac Pro 4,1 .66 ghz, 8 GB RAM
Mac OSX 10.6.8
Dual monitors, two internal hard drives (internal; drive A, internal drive B), multiple external FW hard drives attached
I have already done the following:
Disk Utility: Verified and Repaired Disk Permissions
Disk Utility: Verified Disk, Repaired Disk - this found errors, and suggested reformat/reinstall
I have already booted off internal drive B and ran Disk Utility, then restarted and booted off internal drive A again. No difference.
I have Time Machine backups on an external 1 TB FW drive.
Late last night, I restarted, inserted my original Snow Leopard DVD, launched the MacOSX installer. Recovered a prior system by choosing Utilities > Restore System From Backup, selected a Time Machine backup a few days old (a day or two prior to the problem begining) on the external 1 TB FW drive, and initiated the restore. The estimated restore time was about 5 hours, so I went to bed and let it run. Got up early, and checked: it said the Restore operation was successful. I was relieved. But the same conditions continued - launching or rolling over the items listed above cause the same freeze/crash/hangs. Hangs on shutdown, only way to kill things is the power button. So now I'm disappointed.
I do have multiple backups of my data files across the external hard drives, but this is a large machine with a lot of stuff on it, and I'd really like to recover things wholesale, rather than having to reconstruct accounts and other things. Before I go to bed tonight, I'm going to take another shot at recovering the system from a Time Machine backup - this time, I'll pick a backup that's from a full week before the problems started (the idea being that maybe the backup I picked last time was not far enough back from whatever incident caused all this).
If the week-old Time Machine backup works, great. But if not...any suggestions?
Additional data points...
Nothing new was installed or updated (as far as I know, and I generally pay attention) in the days prior to the problem.
The last thing I recall doing on the computer before the problem began, was burning a DVD (using Toast) - something I do all the time. After that operation, I tried to shut down, and it froze.
The primary internal hard drive partition (internal drive A) seems to be the only one that's having trouble: if I reboot off of internal drive B, the problems do NOT occur - no hang on quit, etc.
That suggests it's not a hardware problem (logic board, etc.) but is something about the System on drive A.
It *could* be bad sectors on drive A - but I have some questions about that...
When I did the full system recovery via the MacOS installer (pulling the old system from Time machine), does the destination drive get reformatted? I don't recall being asked the usual partition/formatting questions.
When the installer does a system restore, does it do any integrity checking on the target drive, or does it just blindly lay down bits?
Does this "freeze on shutdown" (and related behaviors) sound familiar?
Any tips/suggestions to fix this?
Thanks in advance.

More info and a question...
Did another full restore (from a Time machine backup on an external drive) last night - picked a backup from from 10 days ago, long before things became problematic. Still having the same issues.
So, I'm thinking the next thing to try is a low-level reformat of the internal drive(s) and then restore again. I have a couple questions about the finer points of that...
I'm following the instructions in this KB document: Mac OS X 10.6: Recovering your entire system.
Inserting my original Snow Leopard DVD, launching the MacOS installer, restarting, in the installer choosing Restore System from Backup. It appears that there is no re-formatting of the target drive in this case - it just over-writes.
My questions...
The contents of the target drive are going to get wiped and overwritten anyway. Do I have anything to lose/to risk by reformatting FIRST (using Disk Utility), then booting off the install DVD and restoring then?
My 1 TB internal drive is partitioned into the primary 750 GB partition (which is the problematic one) and a secondary 250 GB partition (which boots and runs fine). The secondary partition has some data I would prefer not to lose. I assume that if want to do a full reformat of the internal drive, that means the whole drive - both partitions - will be wiped (that is, I cant reformat just one partition on a single physical drive without reformatting the second partition). Correct?
I suppose I can back up the data that resides on the second partition to an additional external drive (I have extras) if needed - not a huge deal.
Do my new partition sizes need to exactly match the sizes of the original partitions? Neither is completely full, but I want to make sure that I will be able to restore the system and contents of the primary partition even if the new partition size is not bit-by-bit the exact same size as the old partition (I assume the new partition size just needs to be large enough to hold the backup - correct?).
So....I'm looking at the following sequence:
Back up the data I want off the secondary partition to an external drive
Boot off the Snow Leopard install DVD
Run Disk Utility and reformat (fully erase) the internall 1 TB drive
Partition that 1 TB internal drive to (more or less) the two previous (about) 750 GB + 250 GB partitions
Restore a recent Time Machine backup (from an external FW drive) to partition #1
Reasonable plan? Anything I'm missing here? Any other steps I should take?
Thanks for any help.
