  • Grey screen on shut down

    Every once in a while when I go to shut down my Mac Pro, it doesn't quite shut down, but instead I get a grey screen that is in several languages, and says to hold down the power button and restart the computer. After I do I get a note that the OS had quit. Everything seems fine after the restart. THis happened about a month ago, but I attributed it then to a laser keyboard and mouse that had been giving me trouble. When I replaced them, the problem stopped, but it happened again last night. Does anyone know what might cause this problem and is it something to worry about.

    Kernel panic.
    I'd refer to an FAQ and work through all the steps.
    Heat, hardware, RAM, and more common with Leopard but can be triggered by software.

  • MacBook Pro goes grey screen, then shuts down randomly

    My MacBook Pro (just purchased 3 months ago, not retina) shuts down unexpectedly. The screen goes grey, then it just shuts down after a few minutes. Anyone else have this problem? Any ideas how to fix?

    You need to reset the SMC on your Macbook.
    * Shutdown your MacBook Pro
    * Connect the power adapter to your Mac
    * On the MacBook's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
    * Release all keys and the power button at the same time
    * Boot your Mac as usual

  • Yosemite - Grey screen and shut down

    I Upgraded to Yosemite last night. Now When I boot the machine I see Grey screen with a time bar and then blank white screen and then it shuts down

    Hi ..
    The startup disk may need reparing.
    Startup your Mac while holding down the Command + R keys. From there you should be able to access the built in utilities to verify and repair the startup disk and restore OS X using OS X Recovery

  • My screen just shut down and it wont turn on

    My screen just shut down & wont turn back on What can i do?

    What happens if you try a hard reset?  To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.  You may need to attempt this more than once. 
    Otherwise, connect it to an external power source and leave it to charge for a little while and then try a reset again if necessary.

  • On start up I get grey screen with wheel turning but it goes no further

    On start up I get grey screen with wheel turning but it goes no further

    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 startup failure is to secure the 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 the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from 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.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, boot from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start 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.
    d. 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
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up 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.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up 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, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup 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 restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the 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 restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.   
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

    At startup I get grey screen and a folder with a flashing question mark.  How do I reset my MacBook Pro to the manufacture defaults?

    Click here and follow the instructions. If the computer originally shipped with Mac OS X 10.6.8 or earlier, when you reach step 5, insert its original disk, restart with the C key held down, use the Disk Utility to erase the internal drive, and install a fresh OS.

  • How can i get my mac to shut down correctly?

    This problem started a couple of days ago. I'm speaking of my iMac which is running Mac os Mavericks 10.9.4, it uses an Intel Core 2 Duo cpu as well. Recently when I shut down through the Apple button --> Shut down it simply goes to the white screen with the spinning gear at the bottom and it keeps spinning and does not shut down. The only way I can get my computer to shut down now is to force a shut down with the power button during an attempted shut down or just forcing it to shut down before trying to correctly shut it down through the Apple button --> Shut down. Please help, I've tried resetting the SMC as I've seen in other posts about this topic and any of the other issues that fixed it aren't my issue, I've checked. I'd appreciate any help given to try to fix my computer. Thank you in advance.

    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Step 1
    For this step, the title of the Console window should be All Messages. If it isn't, select
              SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar at the top of the screen.
    In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
    Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
    For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
    If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
    ☞ When posting a log extract, be selective. A few dozen lines are almost always more than enough.
    ☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
    Please don't indiscriminately dump thousands of lines from the log into this discussion.
    Please don't post screenshots of log messages—post the text.
    Step 2
    In the Console window, select
              DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
    (not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
              View ▹ Show Log List
    from the menu bar.
    There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent of each. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
    I know the report is long, maybe several hundred lines. Please post all of it anyway.
    ☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
    ☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

  • Shut off screen without shutting down accelerometer in Touch

    Due to Apple firmware limitations in the 2G iPod Touch, it is not possible to shut down the Touch screen and keep the accelerometer running, so running the Sleep Cycle application on the iPod Touch causes the screen to stay on all night and become very warm
    Apple please please could you change the Touch firmware to support shutting off the screen without shutting down the accelerometer so that Sleep Cycle can be run on the Touch like it now runs on the 3G and 3GS iPhone.
    This would open this excellent little application to the whole Touch market segment, making the developers very happy and allowing me to get up in the morning.

    This is a user to user forum and Apple will not hear you. You can address Apple directly here: http://www.apple.com/feedback/ipodtouch.html

    Hi there DerVogel ,
    Sounds like a Heat related issue ????????
    Whenever it shutdown automatically does it turn on right away ? One symptom of a heat related issue is, it takes about several minutes before you can turn it back on again.
    Here is how you can isolate the issue since it could also be a software related problem.
    1) Turn on the system Tap F2 and boot on the system setup screen ( BIOS )
    2) Just stay on the Bios , If it doest shutdown on the bios then you might need to reinstall windows. or check if system is infected with spyware or a virus.
    But if it does the same thing then the best thing to so is to bring it to a Repair Center or Call Tech support for a depot service repair.
    Cheers ! hope this will help.

  • Screen unpredictably shutting down during phone calls.

    Anyone understand the logic behind when the screen shuts off during a phone call.
    I'm using the keypad a fair bit and sometimes the screen will shut down during a call, hiding the keypad. I can shake it and it will come on again but then sometimes it goes away.
    Sometimes it just stays up the entire call.
    Sometimes it shuts off during the call.
    If it shuts off during a call I can shake it to get the screen to come on.
    Sometimes it just stays up for the rest of the call.
    Sometimes its shuts off again.
    If it shutss off during a call I can shake it to get the screen to come on.
    Repeat...
    Quite frustrating. How do I get it to stay up?
    Can I?

    My iPhone does the same thing. When I make or receive a call the screen seems to do the opposite of what it should do. When I put the phone to my ear the screen activates, when I pull it away the screen locks. This causes me to press the touch screen when talking on the phone, buttons like mute and keypad.. highly frustrating. Also when I try to hang up, the screen locks preventing me to end the call.. have left numerous unintented voicemails due to this.
    I have tried adjusting the auto-lock setting but this does not help and is up-to-date. Any ideas?

  • My ipad showed a blue screen and shut down.

    My ipad showed a blue screen and shut down.  I cannot restart it.  A soft restart did not work.  I tried connecting to iTunes on the PC but it did not detect the device

    Did you try resetting the iPad?
    Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears- let go of the buttons.
    If that doesn't do anything, try this for the issue with iTunes not seeing the iPad.
