  • Mac pro will not restart.

    When I try to update software my mac pro will not restart. So the software does not update. What to do? I have tried unpluging all external drives. No luck. The screen just stays in the infinity picture. I have tried waiting 5 minutes. Still no restart.

    You are still using 10.6.8, just to confirm, so you don't have Recovery Mode for one thing. But do you have a backup that is bootable? make one now before you do more. And try repairing the drive as well as doing a Safe Boot.
    You may need to do a clean install to another drive. Apparently you have another Mac or something to post and get online so you could also use Target Disk Mode to access the system in trouble.
    Update with what from what? what other internal drives are there?

  • Mac Pro will not restart from dropdown menu

    Hi all,
    My Mac Pro will not restart from the dropdown menu or when clicking the 'restart computer' when installing software updates. I have an external firewire hard drive hooked up as part of my backup process. It contains a clone of my startup disk.
    I have tried disconnecting the firewire drive, rebooting then attempting to restart from the dropdown menu. Still no joy. I always have to end up shutting down manually by holding the power button in and then restarting with the power button.
    Any thoughts?
    Thanks in advance.
    Dennis

    You might try Safe Mode (It will take more time to startup in Safe Mode because it runs a directory check.)
    If your Shutdown functions correctly that way, go to System Preferences >> Accounts >> Login Items, and remove them. Boot normally and test. If not go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving ~(yourHome)/Library/Fonts to your desktop and restarting.
    Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
    EDIT: Also, if you can launch Activity Monitor in your Utilities folder and see if you can find the process that is still running.

  • Mac Pro will not reboot after Bootcamp attempted installation

    I have an older quad-core 2009 Mac Pro. I tried to install Bootcamp before realizing that it's not supported. Now the Mac Pro will not reboot.
    It starts up fine. It shuts down fine. But it just will not reboot. When I try to reboot, it just clicks like it's trying to boot to a DVD or a drive that's not there (I have since formatted the drive I was using for Bootcamp and use it for Time Machine now).
    This is what I have tried:
    - PRAM reset
    - SMC reset
    What could be keeping my Mac Pro from rebooting properly?? Please help. Thank you!!

    So you tried with Mac and Windows on same drive?
    And you have Recovery partition.
    You made a clone with CCC as well and cloned the Recovery
    Paragon makes a couple programs to make life easier.
    And, Well, Boot Camp works. There are unwritten rules. There is a forum devoted to it.
    2009 is not old. Old is pre-2008 due to UEFI / EFI64 and how Windows 64-bit now looks during install.
    It did install but the drivers and updates and such might be an issue.
    Apple does not support HFS arrays, not just that Windows won't install but to mount, their Apple HFS driver.
    You left out so much and maybe your IT didn't include Windows on Mac.
    www.apple.com/support/bootcamp
    In general pull all your drives during install except that one Windows will be installed on.
    Do get video driver from ATI etc yourself
    Tell us what version, I assume Windows 8 which works fine other than a few issues - more with MacBook series and iMac or Mac Mini lines.

  • Macbook pro will not restart after failed disk repair

    This has happened twice in one week.
    A routine disk verify was performed and returned errors.  I reboot into the recovery drive and run disk utility.  To validate the first finding, I run disk verify again. Same failure.  Then I run repair disk.  Disk repair fails. After this, the system will not boot.  Now, even the disk utility 'sees' the main particitian, but it's grayed out.  when i go to retore Lion, the main partition is not seen at all. 
    The kicker is that two different hard drives are involved.  The first is a 500 gb Western Digital and the second is a 750 gb seagate. System is a mid-2009 MBP with 8gb ram. 
    I performed a full system backup this weekend but do not have it with me and will not have access to it until this weekend.  Any help out there?  Or am I just screwed?

    Oh by the way, a mid-2009 MacBook Pro would not have 10.4.6.   In fact it might not even have 10.6.4.   10.6.4 didn't get prebundled until June 15, 2010.   So where you get 10.4.6 on your signature, that confused people as to what you really have.

  • Mac Pro will not boot with Snow Leopard - need help!

    I have had a lot of issues with Snow Leopard since I upgraded from 10.5.8. Most of my problems started after installing Office 2007. I finally wiped the hard drive and reinstalled everything. No problems until last week. Start up was taking longer and had to reboot a couple of times because of grey screen. So I would just put computer to sleep. Yesterday the computer was frozen on screen saver with scrambled rows of pixels on screen two and the main monitor had a frozen image.
    I initially pulled all peripherals out and pulled the power plug for 5 minutes. I have left the peripherals out and pulled the second monitor as well. I tried pulling the power plug during a few more starts but nothing gets me to a complete start up screen.
    I have tried resetting PRAM and VRAM and tried a safe boot. I tried booting from Snow Leopard and my Leopard disk stayed on either a blue or gray screen with spinning beach ball (on gray screen).
    Put original install disk in and booted from using D to check the hardware. Good news is that the hardware test was OK. I did the extended test.
    All different kind of start up problems.
    - Some start with start up sound goes to Apple logo to blue screen to grey screen with beachball
    - Some start ups with no initial sound then Apple logo to blue screen to grey screen with no cursor or beachball
    - Some start ups with no sound to gray screen to blue screen to grey screen.
    I have no problem wiping the HD1 again but I can't even get the OS disk to be recognized with holding the C key during start up. This last time it went to a blue screen (holding the C key) and a cursor.
    I don't know what else to do - Please help!!!

    There are lists (MacIntouch and MacFixit) of hardware / software support issues with 10.6. Accelerateyourmac is another place to watch.
    There were some really long threads back in Sept about printer driver support.
    The 7300 firmware was more about Windows support; those cards are failing and dropping like flies (how DO they know 3 yrs has expired anyway?) and they don't support SL features like OpenCL etc so I'd invest in ATI 4870, best graphic card and works in all models Mac Pro.
    Lots and lots of bootable clones for backup. Never need to wipe and install again.

  • MAC Mini does not restart after Yosemite update

    I bought my MAC mini in 2011 and I successfully updated to Mavericks with no problems.  I am not sure why my MAC Mini will not restart after I updated to Yosemite. The completion bar gets stuck around 30%.
    Any help or ideas appreciated 
    Larry

    Okay, this is strange.  I tried restarting three times yesterday with the same results. In fact I left it go overnight only to find the next morning that the bar was still stuck at 30%.  I did a hard boot a little bit ago and waited a few seconds. I restarted an it booted up fine.

    Note that you don't have a Mac Pro as stated. Your profile says you have a MacBook Pro. Please clarify as they are entirely different computers. If nothing below works for you, then make a Genius Appointment and take it in for service.
    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
         computer and after the chime press and hold down the OPTION key until the boot manager
         screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed.

  • 2009 Mac Pro will not boot up under Windows

    I have an Early 2009 Mac Pro system (Mac Pro 4,1) and I've had this system for 3 years already and have been working under OS X with this system ever since I purchased it.
    However, when I tried to boot off my Windows disk, something very interesting happens. The Mac Pro WILL NOT boot up off the Windows disk or a known working Windows partition if two monitors are connected. Upon holding down the option key and selecting the Windows partition, I will get a black screen on one monitor (the one connected via Mini Displayport) and the other screen receives no signal and will enter standby and the system is halted. It does not respond to keystrokes, there is no hard drive activity, no measured power increase on the UPS, no apparent network activity, nothing. The only way to exit this scenario (from what I can tell) is to power off the machine, disconnect the display on DVI, power on the machine again, select the Windows partition wait for the system to reach the login window and reconnect the DVI monitor (at which time Windows recognizes it immediately and the system works fine again).
    My question to the community is, does anybody know why this is happening and is there a known fix for this? Quite frankly, having to disconnect a monitor just to restart is very tedious and frustrating. 
    I have two Samsung P2350 monitors attached to an ATI Radeon HD 4870 (512MB, from Apple). One is monitor is connected via directly DVI and the other is using a Mini Displayport to DVI adapter. Both monitors work fine under OS X with no issue. At first, I thought that this may be a driver issue on the Windows side and after installing all the latest updates and drivers the issue is still apparent. From what I can tell, this doesn't seem like a software issue but rather a firmware or EFI issue as this happens before Windows even loads.
    If anyone knows of a fix or what to do in this situation, or if you are also having this issue, I would love to hear your input!
    Thank you!
    For the record, I am running all the latest software builds on the OS X side (10.7.4, not that it would really matter at this point). I have also disconnected all unnecessary equipment in a trial and error scenario but the results are still the same.
    The system passes all ASD testing.
    The full specification of the computer and all connected equipment are as follows:
    2009 Mac Pro (4,1) 8-Core
    2x Intel Xeon Nehalem 2.66GHz Quad-Core CPUs
    16GB DDR3 ECC 1066MHz RAM (Apple Branded)
    Two OWC 120GB SSDs (One for OS X, the other for Windows 7 x64) - These are in place of my optical drives.
    4x 2TB WD Black Hard drives for storage.
    Two Samsung P2350 Monitors connected via DVI. (One using a Mini Displayport to DVI adapter).

    In Windows I am using the latest (12.4) Catalyst Software Suite, 64 bit of course, downloaded directly from AMD's site after installing the drivers from Boot Camp.
    As for installing Windows I used an original (not burned) installation media (Disk is in a pristine condition). And yes, Windows is fine, the problem just seems to be getting the system to boot up Windows with that second monitor. However if the "problem monitor" is disconnected the system boots fine 100% of the time and connecting it later after booting the system will still operate properly.
    For the sake of arguement I swapped monitor cables and connected the "second" monitor to the mini displayport adapter to verify that it wasn't a cabling issue and I'm still yielding the same issues.
    As for GPU testing, I've played games (Crysis, Grand Theft Auto IV, Battlefield 3, etc.) and I've had no issues with the card or stability.
    You would think that Apple would try to find a fix for this, especially considering the caliber of this machine.

  • System upgrade on MacBook Pro stopped and my MacBook Pro will not restart.

    MacBook Pro will not restart.

    Reinstall OS X without erasing the drive
    1. Repair the Hard Drive and Permissions
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    2. Reinstall Snow Leopard
    If the drive is OK then quit DU and return to the installer.  Proceed with reinstalling OS X.  Note that the Snow Leopard installer will not erase your drive or disturb your files.  After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    If you are unable to get it working using the above, then you will need to try this:
    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it.
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.
    And, if this doesn't help, then the HDD is failing or has failed.
