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.

  • 2008 Mac Pro Hangs

    My 2008 Mac Pro with OSX 10.6.8 Model 3.1 just started to 'hang" for about 40 secs. periodically while browsing any website. Problem occurs with both Safari 5.7.1 and with Firefox. Internal temps appear to be OK. You can browse OK for a few seconds or so then it will hang again, then will be OK for a few seconds then will hang again. I haven't added or removed anything at all for several days. Tried restarting computer and doing an SMC reset with no help.
    Anybody have any ideas?
    Thanks for any help,
    B. Taylor

    If instaled, try temporarily disabling anti virus software.
    If you don't have a/v software installed, try a different DNS server.
    Open System Preferences / Preferences then select the Network tab. Click the Advanced tab then click the DNS tab.

  • Why does my mac pro hang when restarted?

    If I go to restart or shutdown my Mac Pro Intel, it starts to restart then the screen stays grey with only a dial showing spinng around (not the beachball just a lined circle that rotates) and there isnt the Apple Logo either just a grey screen. I have to hold down power button to get it to restart. I have 12gigs of memory in it. Its a dual core Intel Xeon running Lion OSX 10.7.2. Is there a program that I could run to find out why it does this? I am fairly new to Mac.

    Hello, I am facing a similar issue. Did you happen to find a solution?

  • Mac Pro Hang!

    When surfing various sites (dopesn't seem to really make a difference...)
    safari, firefox and chrome all develop a hang that requires a manual shutdown - here's a sample error log:

  • My Mac Pro ONLY Boots up in safe mode

    My Mac Pro hangs in boot mode forever (screen after the Gray Logo Screen).  I'm unable to use the recovery partion, or boot from USB installation.  I did all the usual troubleshooting e.g. reset SMC, NVRAM, etc.  I tested the boot drive externally on an iMac and boots just fine.  I checked the permissions running Disc Utility and get a lot of the "display" plists have the wrong permission settings.  Does this mean my graphics card is bad?  The Mac Pro is the stock 2006 model, 2.66 Ghz QuadCore Xeon with 2GBs or RAM.

    Thanks for your help Grant Bennet-Alder. I've tried this as well. When I boot up holding the Option key, the screen shows both the Recovey_HD and the Boot Volume graphically.  Whether I choose by clicking on the Recovery_HD or the main Boot Volume the same thing happens - the screen after the Gray Apple Logo Screen.  I tried booting by this same method with my old installation discs that came with the Mac Pro to see if I can just install a new System folder and it triggers the Kernel Panic screen (See Below - Grayed out screen with Black Pop Up saying "You Need to Restart Your Computer..." Seems I can't even restore my Mac.

  • Mac Pro 1,1 hangs indefinately at startup: Help Me Diagnose?

    Hello all, trying to determine what could possibly be causing this issue with my Mac Pro Quad 2.66 xeon machine running Snow Leopard.
    It will turn on but does not boot up, instead hanging indefinately at the white screen with apple logo, displaying a perpetually rotating load icon.
    Perhaps the pros can help me figure this out...
    Here are what may be some relevant details:
    -Will not boot to system install disk
    -Does not take keyboard command for auto disc-boot (c on startup).
    -DOES take keyboard command for boot disc switching on startup (option on startup).
    Sees install disc via this method, but machine will not boot to it.
    -Only very recently, machine turns on automatically when simply plugged in, without the need to press the power button
    (this started last night after the machine has been off for days).
    -There are no error LED lights anywhere, on the logic board nor on the RAM risers.
    Here are some steps I've taken so far:
    -Removed hard drives to attempt forceboot to install disc and rule out a system drive issue; no change in symptom.
    -Set up various RAM configs to check for RAM problems: no RAM, one pair of each set on Riser A, swapping risers, etc; no change in symptom.
    -Failure to boot to Install Disc with any button combo at startup suggested some sort of optical drive problem so
    removed optical drive completely; no change in symptom.
    I am baffled by this, and while it is an older machine with the 'known issue-laden' Nvdia GeForce 8800GT dual graphics card,
    there are no graphic anomolies whatsoever. I have the Arctic Cooler S1 heatsink/fan system in there and so always been nice and cool.
    Any ideas folks? This has brought my studio to a complete standstill
    Thank you kindly for your input and happy friday to you!

    By the way, Ive done the Verbose mode and there are, as you guys stated, mostly lines of information I cannot understand. However, some things that stuck out as possible negatives with words like 'failed' appeared,
    perhaps these lines they will look like something to some of you...
    Most notable were the final lines at the bottom of the verbose readout page,
    (reads as such but on single line):
    launchctl: CFURLCreateDataAndPropertiesFromResource(/System/Library/LaunchDaemons/com.appl e.auditd.plist) failed: -10
    immediately following was another launchctl line, seemingly related to the previous:
    launchctl: no plist was returned for: /System/Library/LaunchDaemons/com.apple.auditd.plist
    then yet another launchctl line which read (all on one line):
    launchctl: dubious permissions on file (skipping): /System/Library/LaunchDaemons/com.adobe.Switchboard.plist
    then this one:
    launchctl: please convert the following to launchd: /etc/mach_init.d/dashboardadvisoryd.plist
    The very last line on the verbose readout page reads:
    Notice: new kext com.paceapp.kext.pacesupport.snowleapord, v5.7 matches prelinked kext but can't determine if executables are the same (no UUIDs)
    Another thing that stuck out was a line after the details of launching and bootup sequences (simply details powerup, verbose startup etc.) but then this line appears afterword:
    Bug: Launchctl.c:3557 (23930):17: ioctl(s6, SIOCAIFADDR_IN6, &ifra6) ! = -1
    at the very top of the readout, there are seven lines referring to 'processors', looks like this:
    AppleACPICPU: Processor Id= 1 LocalApicId= 1: Enabled
    AppleACPICPU: Processor Id= 2 LocalApicId= 7: Enabled
    AppleACPICPU: Processor Id= 3 LocalApicId= 6: Enabled
    AppleACPICPU: Processor Id= 4 LocalApicId= 0: Disabled
    AppleACPICPU: Processor Id= 5 LocalApicId= 0: Disabled
    AppleACPICPU: Processor Id= 6 LocalApicId= 0: Disabled
    AppleACPICPU: Processor Id= 7 LocalApicId= 0: Disabled
    There is a line about mid page that reads as such:
    BSD root: disk0s2, major 14, minor 2
    anyway, not sure what any of it means but thanks again for reading and for all the advice.
    Best,

  • Late 2013 Mac Pro freezes constantly - GPU Hang

    I've been having a very consistently recurring problem with my brand new Mac Pro freezing. I am unable to predictably reproduce the problem, unfortunately, which makes it hard to solve or troubleshot from the get go. Basically every time I boot up I get a full freeze of the machine anywhere from within the first 10 minutes to an hour of boot up... somewhere in that window usually. Whatever applications are open will freeze, including system OS and usually only the mouse will be able to move but I will not be able to click on anything or Force Quit or restart. My only option is to hard reboot by holding down the power button for several seconds.
    It doesn't seem to be isolated to occurring with any one application being open. I use my computer primarily for audio recording and editing. I use Avid Pro Tools HD 11.2. It's a version of their software supported to run on Mavericks 10.9.3 which is what I am running. I use it with their HD Native Thunderbolt hardware. Other than a few drivers installed to run audio and MIDI interfaces connected to the machine, I don't have much else installed on the computer yet. I do have a few 3rd party audio plugins installed, however, these problems were occurring before I installed much of anything on the machine.
    I've checked Console each time I have the freeze ups and scroll to the log at the time it occurred. Almost every time without fail I get basically the following message in the Console log:

    It's almost always saying something about a "GPU Hang" at the time of freeze up. I don't know much about what the possible problem could be but some initial research led me to believe it was graphics card related. I thought that because I was running two monitors perhaps the connections there were fouling up somehow. I am running two identical monitors simultaneously. One runs off a regular HDMI cable. The other was via a 3rd party Mini DisplayPort to DVI adapter. I thought perhaps the non-Apple branded adapter I was using could be the culprit? The Apple Store (of course) agreed and sold me the Apple DVI to mini DisplayPort adapter. I swapped it out but it did not solve my issue. Still having the freezes. Sometimes after the freeze happens I'll also get a pop up warning that my external hard drive connected via USB was ejected improperly, even though I hadn't touched anything?? The whole thing goes haywire.
    It's been doing this for a few months now. I've contacted Apple Care and spent an hour on the phone with them which resulted in making an appointment at a local Apple Store with a Genius. This was after they recommended that I reset both the SMC and the PRAM on the machine, neither of which solved the issue either. I took the machine in and they kept it for 48 hours to do a full stress test to see if they could determine the issue. No problems were found. They gave me the computer back and could not reproduce my problem.
    The problem still exists. So that's why I'm writing on here, out of desperation because I have a brand new Mac Pro, under warranty, that is essentially useless. I have a follow up call into Apple Care to see what my next steps are but I haven't gotten a call back.
    The only next steps I can imagine are to possibly update to Mavericks 10.9.4 to see if that might help even though Pro Tools is not yet supported by that OSX version yet. Or do a full clean re-install of OSX and all software on the computer (yikes!).
    Or Apple needs to swap me a new machine. This is unacceptable.
    Anyone else having this issue??

  • New Mac Pro and 9.2 Hangs on Adjustments?? Old G5 Doesn't

    Hello
    I have what should be a very fast new Mac Pro.  6 core at 3.46Ghz.  48Gb of RAM.  Solid state boot drive.  Software RAID 0 with 2 Hitachi 3TB drives, hardly anything on them yet. Nvidea Quadro 4000 CUDA card.  Everything installed and burned in for the overnight 8 hour test with the MPG workstation program at OWC.  Lion 10.7.2.
    I had approximately 700 in camera photos combined still in camera between an up-to-16MP Sony NEX 5N camera and up-to-24MP pics on a Sony A77, that have already been loaded into my 6-7 year old 2.4Ghz dual core G5 with 6.5Gb RAM and much older version of iPhoto. OS 10.4.7 I believe. 
    Last night I loaded all those same pictures into the new machine and 9.2 version iPhoto.  And then deleted them from the cards on both cameras.  No issues. Smoking fast imports compared to the G5 which wasn't all that bad.
    On the G5 with the picture adjust controls I could use the slider to go deeply into those same photos and see the effects of contrast, sharpness and all the other options.  Like butter.  Make the adjustments while in that deep if desired and then pull back to evaluate the overall picture before saving.  Or back in again if desired. No issues.
    With the new rig I couldn't wait to try all of this, but once I go deep inside and start to move the adjustment slider controls the system every time starts getting hung with the spinning wheel.   Have to wait and wait for them to catch up to the curser on that adjustment.  Most of the time the system then will just get stuck and I have to force iPhoto to quit.
    Please....does anyone know why all this latest powerfull hardware and software is doing that, compared to the old, much less capable G5?  I am really concerned now.  Haven't had a chance to get Photoshop and the other production premium software tested yet.
    And one last question please.  Does anyone know if the "Enhance" feature in the Quick Fixes section adjusts Gamma as well?  There seems to be a lot more going on to give the photos depth (what I always really try to do)   than the sum of the small slider movements in the Adjust section.  With my old system and iPhoto version there was no "Gamma" adjust slider in iPhoto proper......but if I saved a photo first to my Desktop for instance, and then called up the adjustment features, there was a Gamma slider there.  Very handy and appreciated.
    I see similar vast improvements on some photos now with the "Enhance" feature that looks like maybe Gamma has been optimized as well?  There now is no Gamma slider available even if the photo is taken to the desktop first.
    Thanks much
    Ron

    Hello Terence
    Thanks for the tip to try.  Couldn't get to it until late last night.  Seems to still be the same in Library 2.
    Also seems to be worse with 27" Cinema Display at full resolution.  And with several sliders on adjustment.  If I drop the resolution to 1920 x 1080 or 1600 x 900 and move smoothly about it is not as apt to hang up.  With as much horsepower as the new Mac Pro has, should resolution of monitor be an issue in these adjustments deep into the pictures?
    How about the Enhance button?  Is gamma involved?  Everything I read about it on searches only talks about boosting saturation of the color and fine tuning with little other slider adjustments.  But on a picture where it has made a big difference to the good with depth and overall look, if I look at where the sliders were adjusted and then undo the enhance, and go back and manually put the sliders in the same position it doesn't look the same.
    Does anyone know if gamma is being adjusted with this button?  Sure seems like it but can't find it mentioned anywhere.
    Thanks again!

  • Mac Pro 3,1 (early 2008) RAID card hangs at startup

    Hello,
    I have a Mac Pro 2.8Ghz Quad Core (early 2008) with 10GB RAM and 512MB VRAM.
    I have noticed that the Mac Pro RAID card hangs at startup for RAID volumes. 
    It seems to start okay with a single boot drive (have used both WD Raptor 150GB 10K and Seagate 'factory' 320GB 7200rpm as boot drives...)
    But the RAID 0 array using two factory 1TB WD 7200rpm is what seems to hang at startup.  I have run Disk Warrior, Disk Utility and RAID Utility and found no major errors...
    Any suggestions?  Have already replaced the RAID Card battery with OEM part.
    Thanks!

    Say good-bye to the Apple Pro RAID card. It started its life as a $999 card to support SAS/SCSI and/or RAID5.
    Then the problems with 2.5TB drives, battery, and does it really do something and add to your system.
    I would use SoftRAID and create a 3-drive mirror of 2TB drives instead.
    And an SSD for the system.
    Seems like those are some very old drives.
    I have a lot of the 150GB 10K VR drives, and some 300GB along with older 74GB and a couple of the Raptor series. Loud and while solid I would use for spare boot drives, clone only.
    Backup your data, pull the RAID card, and restore to the drives. And clone the system onto a 250GB $109 SSD. $139 buys a 400MB/sec writes and 800MB/sec reads Samsung PCIe-SSD XP941. None of my SCSI 15K drives would come close.

  • External Firewire HDD causes hangs on my Mac Pro & HDD lag using finder

    External Firewire HDD causes hangs on my Mac Pro & HDD lag using finder.
    I have an 2008 Mac Pro 8 core 2.66hz, 10GB Mem, ATI HD4870 with 4 internal 1 TB Drives. I have 3 external HDDs (2 USB + 1 FW400). The 2 USB HDDs are for Time Machine and backups.
    The external FW HD is a 1TB bootable clone of my Internal 1 TB boot HDD.
    I have 2 problems ... somethimes when using finder or opening a folder, copying files, starting or quiting a program, I get the spinning beach ball that seems to hang the Mac.
    I power off the external FW HDD and everything starts to work. I get an error about the device going offline, I then power the FW HDD back on and all is good.
    It seems the external FW Drive tends to hang the system. It occurs pretty frequently.
    Any recommendations?
    The other issue is that when I use finder to go to a folder, I seem to have to wait for all these drive to spin up. You can hear them all start whirring.
    is there a way to remove that lag?

    If you recently moved to Snow Leopard you might look for new firmware for your external drive. I would also get DiskWarrior and run that on the external and consider programs like Drive Genius. You might also back it up and wipe it and restore the data. After that I'd consider looking at a new external.
    Sleeping drives that take time to spin up after waking....I'd like to learn how to stop that myself. Be sure the Energy Saver in System Preferences is set to not put drives to sleep when possible. Even then my drives will go to sleep and I have up to 6 external added at times and they take quite a while to all spin up. I've never found a way to prevent that.
    BTW...external USB drives on a MacPro? Really? Even for backup....

  • Mac pro 5,1 / 10.8.2 / 10.0.7 - while working in fcx and the program and the system hangs (freezing)

    mac pro 5,1 / 10.8.2 / 10.0.7 - while working in fcx and the program and the system hangs (freezing). Only moves the mouse pointer. In addition to disconnecting from the mains, nothing helps! what to do?

    Yes, it would if you ran it on the new MBP which is the reason I am saying install rather then clone.
    If you clone then you are only getting the same code as the old MBP which probably will not have the correct drivers.

  • Mountain Lion Hangs on Early 2008 Mac Pro

    I installed Mountain Lion 12A269 on a freshly formatted disk on my Early 2008 Mac Pro. I have 10 GB of memory.
    Once or twice a day, the computer hangs. I can move the mouse cursor, but can't click on anything and the keyboard is inactive. The dock doesn't raise when I move the mouse over it. CMD-OPT-ESC doesn't bring up the force-quit window and none of the menus work. All I can do is hold the power button in to shut down and then restart the computer.
    There's no kernel panic -- the computer just hangs.
    The console shows two System Diagnostic Reports:
    Finder_2012-08-28-093935_Disk.hang
    RPDLAgentHelperE_2012-08-16-14738_Disk.crash
    Since it just hung a few minutes ago (08/30/12) I don't know if either of these files are relevant. Neither one is helpful.
    I'm looking for suggestions for fixing this problem or additional troubleshooting. The computer just hangs -- there's no consistent action to trigger it. It's already resulted in a lot of lost work and productivity.

    The console messages indicate a problem with your disk drive. It may be failing.

  • 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 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

    Different firmware can matter.

  • Bootcamp, intel mac pro, using entire drive, installer hangs- what am I doi

    I have been trying to install boot camp and windows on my Mac Pro. Installing on my MacBook Pro was so easy I didn't expect any kind of problems, but I got them anyway.
    a) I am installing on a hard drive and I expect to use the entire drive. I start boot camp and designate the drive. Windows appears to start installing but when I get the format screen, there is no partition on any drive labelled Boot Camp.
    b) if I choose the drive I wanted anyway, it will format for NTFS and copy all the files. It will re-boot and start the GUI install but hang with 33 minutes to go. I have tried this multiple times and the result is identical every time.
    What am I doing wrong?

    As of this point in time, I have been able to get windows installed- I noticed during the windows setup and format section that the disk actually had two partitions, one very small and the other the size of the rest of the disk.
    (this was probably a mistake) but I deleted the small partition, formatted the large one NTFS and continued with the install. Well, windows went on without a whimper after that and I was able to install the windows drivers from my apple disk.
    BUT when i go to preferences/startup disk to select the BOOTCAMP partition (yes, that shows now) I don't see it.
    If I start Fusion, I can see and boot the bootcamp partition but if I go into the control panel and start the bootcamp control, the mac os partition does not show.
    So, does it sound as though I deleted what apple uses to select between the mac os and windows installations when i deleted that small partition?
    I am afraid to try again.
