Early October 2011 MBP freezes at apple screen

After trying to update  from 10.8.1 to 10.8.2, it tells me that it couldnt update to 10.8.2. Next boot, the system freezes at apple screen. I then try to go to disk recovery, and once in there it says Ive updated to 10.8.2. But in fact it did not let me when I ran the update.

Also... ran machine in recovery... repaired disk but no errors were found.

  • Early 2011 MBP stuck on gray screen, verbose mode shows SMC error too

    Hi!
    I have and early 2011 MBP, running on OS 10.7.5 is continuously stuck at grey screen upon start-up.
    I tried the steps as mentioned in Mac OS X: Gray screen appears during startup - Apple Support article apart from reinstalling OS X. The laptop started after every step, but then stopped again. I tried SMC update, that also worked for once, and on the second start up I ended up with a blue screen. During a later attempt, it worked again for a while, but ended with a distorted graphics after 15 mins. AHT (short version) doesn't show any hardware errors. Now the laptop doesn't go further than grey screen at all, and after a minute or so there's a heavy fan activity. The verbose mode also shows and SMC error, smc: : smcinithelper error: mmio regmap ==null - fall back to old smc mode (AHT Shows SMC version as 1.69f4)
    What do you advise?

    Try this:
    Reset the SMC and the NVRAM:

    Then try a safe boot:

  • Mac Pro (early 2008) No chime, pixelated white apple screen

    My Mac Pro (early 2008) stopped working this morning. It was working fine yesterday, but did not start today.
    i Press the power button, and there is no chime. The fan whirls around and the cd disc drive makes a noise. The startup screen shows up with Pixelated black bars across the whole screen.
    this his stays onscreen, freezes for a few minutes, then restarts And continues the cycle of freezing and restarting.
    iI've tried to reset the smc and pram and that hasn't done anything.
    i've cleaned the inside of the computer, checked the RAM and graphics card, they seem to be in good working order.
    does anyone know what's wrong with it?

    Hi BDAqua
    i tried safe boot. The white apple screen still comes up pixelated but with a grey loading bar at the bottom. Once the bar has loaded fully, nothing happens. it stays frozen on that screen until I have to force it to shutdown by pressing and holding the power button on the front of the tower.
    i Tried holding the alt key. It brings up the devices, the screen is still pixelated. Pressing either one of the disk drives, didn't do anything new Unfortunately.

  • MacBook Pro (late 2011) stuck at white Apple screen.

    Hi all. My MacBook Pro 13 inch (late 2011) is giving me the same problem over and over again. 
    Few months ago, I had sent it to Apple for repair due to faulty HDD. Now the same problem happened again. The MacBook will stuck at the white Apple screen with the circle turning when attempting to switch on.
    However, Apple had just replace a new HDD and why it's still happening again?
    Can anybody here please assist to advice me what is making my Mac unable to start up, stuck at the white Apple screen, even after replacing a new HDD?
    Thank you!

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 3
    Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
    Step 7
    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
    Step 8
    A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • IBook G4 Freezes at Apple Screen - Disc Space Full?

    Hi Everyone,
    First time here on Apple Discussions - thanks in advance for all the help. I have an iBook G4 (late 2004, I think). While using the computer I started seeing messages telling me that my disc space was close to full and that maybe I should eliminate programs. I also just installed new (more) RAM - I've upgraded from 256mb to 1G. Unfortunately, I updated my iTunes and then when I rebooted my system in order for changes to take effect, the computer never booted back up. Now when I press the power button I hear the start up chimes and fans but the process stalls when the gray Apple screen appears. I have tried to reset the PMU but have not had success. Any help would be much appreciated!
    Thanks,
    Gary

    Hi Gary:
    Welcome to Apple Discussions.
    A too full disk is a dangerous condition, as you are discovering. You need to maintain a minimum of !5% of total capacity (5 GB on HDDs 40 GB and under) as contiguous free space for swap files and to grow the Extents Overflow file of the directory, otherwise you can end up with a very lethargic drive, and worse, directory corruption, corrupted and possibly lost data.
    So, where do we go from here? I would begine with Repair Disk
    Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
    Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
    Select your HDD (manufacturer ID) in the left panel.
    Select First Aid in the Main panel.
    (Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
    Click Repair Disk on the bottom right.
    If DU reports disk does not need repairs quit DU and restart.
    If DU reports errors Repair again and again until DU reports disk is repaired.
    If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
    Please post back with an update and with any questions or comments.

    See if you can run these.
    Run fsck.
    1. Reboot/Startup holding your Command-S key down.
    2. At the command line type the following and hit 'Return.'
    /sbin/fsck -fy
    3. After it has check/repaired your disk, type 'reboot' and hit 'Return' again. Unit will bootup normally
    ======
    Do an Open Firmware reset: Hold the CommandOption+OF keys during startup. At the '>' prompt type:
    reset-nvram
    Return

  • Freezing at Apple Screen

    So here's my problem...If you can help and it works, Thank you so freaking much.....If you can't, my last option is to send it in..
    So, I got my IPOd a while ago and it worked great for a good amount of time..Sure the occassional reset here and there, but then one time it wouldn't reset....I plugged it into my Comp and reset it and it just stops at the Apple Screen....Dies after the battery runs low and trys again....Sometimes if I reset it enough it'll bypass the Apple Screen and start charging, saying "Do Not Disconnect"...well, when I get that I let it go and fully charge, but when I click off and stop the hardware/connection on the Computer...Unplug the USB, it automatically freezes again..and when i try and reset and EVERYTHING...it just freezes at the apple screen.
    Help? Please?

    Seems your iPod's hard drive isn't functioning properly.
    You might want to try checking the hard drive using Diagnostic Mode.
    Here's a link for how to do that: http://www.methodshop.com/mp3/ipodsupport/diagnosticmode/index.shtml.
    Also, if you have access to another machine, PC or Mac, try connecting your iPod to that one and see if anything changes.

  • Computer freezes at Apple screen, dial stops turning after accidentally turning off computer during Migration?

    Accidentally turned off my Powermac G5 in the middle of a migration from my iMac G4 and now will turn on, but stops at apple screen, dial stops moving. HELP!

    Hello,
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
    If the above fails, then it appears to be time for a relatively painless Archive & Install, which gives you a new/old OS, but can preserve all your files, pics, music, settings, etc., as long as you have plenty of free disk space and no Disk corruption, and is relatively quick & painless...
    http://docs.info.apple.com/article.html?artnum=107120
    Just be sure to select Preserve Users & Settings.

  • IPod Freezes at Apple Screen

    Ok so i formated the ipod with Win Vista, not with iTunes, and since the format was over, it just froze at apple screen. Wont show up on computer, wont restart when i do Menu+Center button. And i can see and hear that it's trying to boot but it keeps restarting, like it's unable to.

    When you say Apple screen, do you mean Apple Logo?
    If so, have a look at these two articles, to give some guidance how to try to restore your ipod.

  • My iPhone will not start after new software update. Freeze on apple screen

    I updated the phone software today through the new software update directly from the phone and it will not restart past the apple screen. I have tried a hard restart, no dice.
    wish I had waited.

    Got it back up and working by putting in recovery mode and restoring through itunes, but lost lots of settings and app. info. I took about 4 efforts to resync after restore, not sure why, certainly not smooth or intuitive. 2 hours of my life I wish I had back.

  • IMac freezes at apple screen with spinning wheel.

    Last night my iMac crashed. When I started it back up, it just stuck at the apple screen with the little spinning wheel. I took it to the Genius Bar and he said to just do a full OS reinstall.
    Does anyone have any other suggestions? I just want to make sure I've covered all the bases before I delete all my stuff. I've run disk utility (from the install disk) and I've also run the Hardware check program from the install disk. Any help would be appreciated greatly.

  • How to Connect Early 2011 MBP 13" to Apple 20" Cinema Display at 1680x1050?

    My early 2011 MacBookPro will only display 1280x800 on an external Apple 20" Cinema Display. The MBP's specs say that it will support dual displays and video mirroring simultaneously at full native resolution on the built-in display and up to 2560x1600 on an external display. The 20" Cinema Display specs indicates that it supports an optimum resolution of 1680x1050. The 20" display is connected to the MBP through it's Thunderbolt port using an Apple Mini Display Port to DVI connector. No luck.
    I've tried using the latest version of SwitchResX set to 1680x1050. It says it is configured to 1680x1050 but the display does not respond.
    Anyone had success setting up this combination of MPB and Cinema Display at the max resolution of 1680x1050?

    To clarify. The MacBook Pro displays 1280x800 and the Apple Cinema Display mirrors it at 1280x800. I cannot get the ACD to display at it's max capable resolution of 1680x1050.
    The MPB has 16GB ram so 512 SDRAM is available to the Intel HD Graphics 3000 chipset.

  • 2011 MBP freezing on external display in fullscreen

    Hey all, had my 15" MBP for a few days now, and I'm experiencing a strange issue. When I have it connected to an external display and am playing a game (Starcraft II, EVE Online) or watching a video in fullscreen (Hulu, etc.) it will sometimes freeze and cause the computer to be completely unresponsive, forcing me to shut it down by holding the power button. However, audio will keep playing in the background. I'm using a miniDisplay port to VGA adapter and outputting to an HDTV. Ideas/comments/suggestions? I'm sure with using a new CPU and new GPU there are some driver issues to work out, just want to make sure it isn't more than that.

    After doing some more tests of my own, I'm convinced that this is a driver issue. This kind of thing is common when a company releases a new GPU and CPU in the same model. (In this case the 6750M and Sandy Bridge i7) Correct me if I'm wrong, but each of you have either the top spec 15" or the 17" model, yes? By now, I guarantee Apple is aware of the issue, and I would expect to see a driver update by, if not before, 10.6.7 is released. Hold tight, my friends. Returning your computer or getting it replaced isn't going to fix this, and neither is complaining to Apple Tech Support (other than that it will make them more aware of the issue). The tech people you talk to have no direct interaction with the software engineers, and aren't going to be able to do anything. They may even recommend useless troubleshooting steps like an OS reinstall. I think we'll see resolution of this once they release a software update, and not before. I've given a link to this thread to a senior level tech advisor at AppleCare, so continue posting your reports here and they will be forwarded to the engineers. Being specific about situation, peripherals, programs, and timing will help them immensely, comments such as "THIS IS BROKEN, FIX IT" are less helpful. Cheers.

  • Powerbook G4 (12" aluminum" won't start up (freezes with apple screen up)

    I'm on the road, and my Powerbook freezes during startup, with the apple on the white background, but no pinwheel. Tried starting in "Safe Mode", and it got to the pinwheel, then process bar/startup, but froze afterwards before the desktop came up. There's a blank blue screen, and occasional flashes of a pinwheel, but no desktop or mouse arrow. Any suggestions that can be done while traveling and without the startup disks (which were stupidly left at home)? Running OSX Tiger.

    Find a local Apple Authorized Service Center who can help you out, tell them first before they do anything whether your data is backed up, and they'll take whatever measures you need:

  • Computer Freezes at apple screen.

    So okay i was online today and was trying to access a file.. when all of a sudden safari just went dead.. then every program i tried to start after that would pop-up in the dock but then shut down ASAP with out ever really starting.. so i figure i restart the computer. Did so.. then the screen with the apple logo and the loading image came on and after 5 minutes didnt go anywhere.. the fans kicked in OVER time and i just shut it off.. did the ram rest thing by holding control, option and p and r and that worked..but it didnt solve the problem..
    Any ideas.. this is a G5 imac without the intel chip.. and i know i am running OS X but not what version

    You have a problem -- however, you may be suffering from a power supply failure, see if you serial numbers are listed in this program power supply or video and power issues, and if they are, call Apple, who will repair your machine free.
