  • Mac Pro will not Boot...Help!!!

    I have a Mac Pro with 4x500GB in RAID 10, well earlier today during normal use my system locked up and I couldn't select force quit or anything my system just sat there frozen and unresponsive. After about 5 minutes I decided to just hold in the power button and reboot.
    Well now when the system boots I get the nortmal grey apple screen and spinning circle thing and after about 1 min I hear each hard drive shut down and the system then turns off.
    I tried holding down the shift key to boot into safe mode but it will not work.
    Please help me get my system back up and running.

    OK well that worked, I shut down the system, pushed disks 2 and 4 back into place, powered back on, logged in and everything looks as it should.
    Well that wasn't too bad, now to get my external data backup in place, I have put that off for too long .

  • I have a mac pro wich will not open windows in boot camp i get to the two options select windows but iyt will not load can you help please

    i have a mack pro which will not open in windows from boot camp get to the two options and select windows drive but it will not open can you help Please

    Hi there, Well, i thing i might have had the same problem (if you dont mean the selecting part, then try keyboad with usb and without if u dont have a macbook pro or so), i did the same and after selecting windows it said "No bootable disk" or " no boot disk" or something like that and the installer wont start when i was trying to install via CD/DVD.
    The sulution is to use 2 usb-drives, one for the support drivers from apple and one for the windows it self after burning the CD/DVD to the usb on a PC using the windows own tools and creating a ISO file.
    (there might be problems whit CD/DVD install sometimes)
    The ISO file on a own USB is the most importat thing!! (and even apple and windows didnt know that but me and a technikal support guy from the store i bought it managed to fix it after like 4 days )
    Hope it work now mate!

  • 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.

  • My Mac Pro is not booting

    My Mac Pro is not booting. We did not use it for a week and when we tried switching it on it was not booting.

    Resetting SMC as well as NVRAM could solve the problem:

    Apple doesn’t routinely monitor the discussions.
    Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.

  • Re: I bought an app - storytime for kids, it had just two books and i downloaded three more books but when i tried to download the fourth book the app is not responding. can you help me? thank you.

    Hi I bought an app - storytime for kids, it had just two books and i downloaded three more books but when i tried to download the fourth book the app is not responding. can you help me? thank you.

    Try force quiting the app.  From the users guide:
    Force quit an app:  Press and hold the On/Off Sleep/Wake button for a few seconds
    until a red slider appears, then press and hold the Home  button until the app quits.
    You can also remove an app from the recents list to force it to quit. See “Opening and
    Switching Apps” on page 23.

    Have you tried logging out of your account on the phone by tapping on your id in Settings > iTunes & App Stores and then logging back in and seeing if that 'refreshes' the account on it ?

    Windows won't give a kernal panic or BSOD because it is a Mac related hardware issue.

    Your asking about a Mac Pro, but those are not "G5" and the OS can't be transferred between PowerMacs and Mac Pro.... are you sure we are talking about only Mac Pros?
    Putting XP and Mac OS on the same drive, that doesn't strike me as what one would do; keep them on different drives.
    And, if they are on the same drive, then you really haven't reformatted the drive, which would involve wiping any and all partitions, and then creating your Mac Standard (HFS+ Journaling) and backup XP with WinClone or install it to another drive.
    I don't have trouble with Windows, but I do with the Boot Camp Assistant and drivers.
