OSX update problem

I ran the last updated yesterday and my Mac hangs after reboot. I have the apple logo and progress bar was clinging to about 75% since yesterday morning. Appreciate any advice on what to do next. Sorry, but I can't patch that was installed, but I keep my mac to update so it should be the last. Perhaps 12.4.3?  Thank you.

At this point, you can it turn off and on again. It should complete the update or return to the previous state. Worst case, it does not start and you need to start to repair and recovery or reinstall OS X. If it's been sitting that long, however, it isn't really all that you can do to kick start it short of a reboot.

  • OSX Update 10.11.3 iMacs causes gray screen of death Mid 2011

    Hello everyone,

    I'm new to the forums of apple, so I don't know exactly if it was to go to the right place. This isn't any question that it's a PUBLIC service announcement.

    Basically, a summary of my post is that OSX update 10.11.3 causes both 27 "& 21.5" mid 2011 iMacs is not start properly. After the update installs and the iMac restarts, the startup sequence seems fine, showing the Apple logo, then the progress bar. However, when you expect your login screen to appear, instead you are greeted with a dark gray screen and movable mouse... and he the system is still a little sensitive. If you press the keys on the keyboard you hear the sound of "bum" as if you had to press a key when you weren't supposed to, and if you press the power button (do not want) the system will switch to standby (and wakes up if you press it again). So this isn't really frozen, it's just nice... it.

    Puzzled, I went to Google, hoping to find someone with a similar problem. I have not found much. I found some people with similar problems (gray screen is a bit more general), but I have found others with 27 "mid 2011 iMacs have this problem (links below :))

    Cannot install the update of El Capitan 10.11.3 (Stuck in gray screen)

    iMac mid 2011, gray screen of death!

    gray screen with the pointer to the login screen

    What I read, some iMacs have been recalled for the failures of graphics card, and that's what some people have responded to in the positions as a possible cause. (This is also what comes mainly from back when you search for "27" iMac screen gray) But this doesn't seem to be the issue here. The above posts are fairly recent and seem to coincide with the update 10.11.3 put in place, and they are the same symptoms that I have experience, but with no working solution.

    Once I have restore my backup time machine last before updating 10.11.3 is installed, the system works perfectly. Unfortunately, if you have not a backup time machine to restore, it seems that reinstall OS x is your only solution (until you reinstall the update)

    I'm not an expert of OSX, but I tried everything under the Sun to try to get the system to boot properly again, like resetting the PRAM & SMC , single-user mode, safe mode, none of this works. The system does not just start.

    I don't know if this has affected everyone with mid 2011 iMacs, but I just thought I'd let people with iMacs 2011 who are having problems with this update that you are not alone, and I hope that someone at apple can be seen. If you have an iMac 2011 that has not been updated to 10.11.3 again, I will not do.

    Thank you

    It is not material, it's software.

    My keyboard came with my Imac aluminum had a problem that I thought was material, but order the update of the post 10.11.2 v works again.

  • iMac restarts after the osx update

    Hi my son has an iMac (mid-2011 Office), and there is an OSX update it will update, but then goes to a screen gray white and just sat there. I've left overnight and does not finish the installation and come back to life.

    I tried to reinstall the operating system via CMD R and I tried first aid on the hard drive.

    If I reinstall the iMac from the time machine backup recovers OK, but I can't get the updates of the OS on the machine.

    So my question is that someone has an idea what could be the cause?

    I contemplate wiping the HD and basically start again, but I have to reinstall MS Office and his Steam account

    Any advice would be welcome

  • Satellite C855 - 2M 1 - AMD graphics driver automatically update problems

    I have a Satellite C855 - 2M 1 and installed windows 8.1.

    I installed the first upgrade of the video driver from Windows update (WDDM 1.2 02/11/2013 9.12.8.0)
    and it works well.

    Lately on windows update has been released a new driver (Advanced Micro Devices, Inc. - Graphics)
    Adapter WDDM1.3 - AMD Radeon HD 7500/7600 Series)
    I tried to update the driver but when windows restarts it does not load the driver and restore the old.

    I tried to manually uninstall the driver and updated, but it fails.

    Any help on this would be much appreciated.

    Thank you
    Andy.

    Hello
    To be honest I m not very well why the autopilot GPU update could not complete successfully, but I guess that the update is not out for the AMD Radeon HD7610M, which is built into the laptop.

    I also read a discussion on this issue in the Microsoft forum, and it seems that there are other people having exactly the same problem with this update.

    [Advanced Micro Devices, Inc. - Graphics Adapter WDDM1.3 - AMD Radeon HD 7500/7600 series update problem | http://answers.microsoft.com/en-us/windows/forum/windows8_1-hardware/problem-with-graphics-driver-update/a7a6da38-6575-405b-86c2-71a620be06b7]

    The question is therefore probably related to wrong or incompatible driver GPU

  • p6310f: Windows Update problem

    When you try to upgrade to windows 10 I received the error message 0 x 80080005 - 0 x 90016 after watching in Microsoft support forum, I found that the problem was related to windows 7 is not not to date. I checked and found that my computer has stopped udating a couple of years. I tried to run Fixit MS that has not worked. Tried to reboot (BITS) and got ERROR 126 (module not found) I then followed the instructions at https://support.microsoft.com/en-us/kb/2700567 on how to reset the Windows Update components. During the process, I have the following errors:

    I guess my question is what I have to do a restore of the system under windows 7, before I can upgrade to windows 10? Or y at - it another way?

    Hello glockrow ;

    Let me welcome you on the HP forums!

    I read your post about windows update problems and wanted to help.

    I would that be able to say that updating to Win10 was an exact science where we know exactly how he does it, and what it should - but the flooding of this and other instances of Win10 problem after that problem indicates that, at best, we are all guessing.

    So, I think, from what I've read and done on my PC, is that you SHOULD be able to avoid the problem of missing updates by updating using Win10 created using this MS link media: 10 Windows Installer using the media - Windows help authoring tool

    After you create the DVD or USB, NOT boot from it. Instead, insert it into your PC and, if it does not auto-start, right click on the file setup.exe and run it.

    HOWEVER - and this is important - PC Win7 have a rate low success updated Win10 without problem - primariluy lack of OEM Win10 drivers.  Typical problems include display artifacts (to cause to be obliged to use the driver for the card of Microsoft Basic), not wireless and touchpad problems.  The drivers Microsoft provides have only the most basic features, with none of the extras that the HP drivers bring to the stage.

    It is further complicated by the function Win10 GoBack, whereby you can return to your original operating system, being known to be unreliable. So when your upgrade machine malfunctioning, only then you discover that you cannot return the machine to work, that you had originally!

    You can protect yourself against ending up with a damaged machine - seriously considering using a free third-party product that works for airport Imaging/restoration - Macrium Reflect.

    Macrium reflect (MR) provides a FREE version that can be used to image and restore partitions or drives together.

    What I recommend is the following:
    (1) download and install Macrium reflect (MR)
    (2) run M. and choose the option: "Create an image of the partition (s) required to backup and restore Windows" to write a full backup to an external drive or USB key
    (3) use the option to create a CD or a USB startup key

    NOW, you have the means to restore a full system that works for the external hard drive or USB key in a few minutes.

    So now you can recharge before with the upgrade, knowing that whatever happens, you will be able to return to your currently works in a few minutes.

    Good luck

    original title: Vista update problem

    When my computer tries to finally start up, it comes to a screen that says Windows Update section 3 of 3, 0% complete.  He is sitting here for a minute or two, then restarts.  This loop continues indefinitely.  Will not start in safe mode.  Used a boot disk to get into the Windows repair and got the result, did not find any problem.  How to cross this attempt to update?  I have Vista.

    When you used the "Startup disk" was available as an option system restore? If so, then choose a restore point created before this issue started occurring.

    If the system restore is not available, then you have 2 options:

    (1) try a "in-place upgrade", aka, repair installation. This can be done by running the system with the "Startup disk" and choose command prompt - How to perform a repair for Vista Installation

    However, if Service Packs have been installed then you should uninstall everything first.

    You will need to know where the Service Pack .exe file is to be able to uninstall the command prompt, because the system does not start properly, or Mode without failure.

    See - method 3: uninstall Windows Vista service pack from the guest here - How do I uninstall Windows Vista service packs as a troubleshooting step

    (2) do a clean install of Vista.

    Hello
     
    Follow the steps and check if the problem persists.
     
    Step 1:
     
    I suspect that your security program may be responsible for this. I would suggest you temporarily disable all security software and try the system restore.
     
    http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Firewall-on-or-off
     
    http://Windows.Microsoft.com/en-us/Windows-Vista/disable-antivirus-software
     
    Note : Antivirus software can help protect your computer against viruses and other security threats.  In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.
     
    Step 2:
     
    As for installing updates is concerned, I you should install them after you put your computer in aclean boot State. There could be a third-party software in conflict with updates. Clean boot helps eliminate these conflicts.
     
    Note: Restart your machine as usual by following step 7.

  • Update problems (Windows 7 x 64)

    A few days ago I got updates not installed nearly 100, but my laptop has been stuck at 0 KB to download and made no progress.  I finally downloaded a Microsoft Tool that is supposed to fix the errors in the software update that claims to fix many things (but except 0 x 80070057).

    Later he enrolled as ever after searching updates, and when I tried to look for it would just get updates constantly without result.  Restores system attempt to before the bug was encountered failed.

    I finally gave up and returned to the factory (from partition) settings, but my new installation has the same problems, so I don't have any update that it is and can not find them with the "search for updates".

    I don't know what to do here exactly.
