HT4623 my app screen has gone blank, how do I fix this problem?

When I open my app store application the screen is blank.  I went into the app store and went to featured items and it just went white.  How do I get my screen back to normal?

Shift-O changes the color.

  • My MacBook Pro shows a grey screen  at start-up how do I fix this problem?

    My MacBook Pro shows a grey screen when I try to login and won't go onto my homepage. Why has this happened and how do I fix it?

    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, start up 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 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 11. 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.

  • The main screen of my macbook is black, but the secondary screen it's ok. how can I fix this problem?

    My MacBook was working with 2 screens but, when the secondary screen was disconnected, the main screen put in black and I can't fix it

    Take your Mac to an Apple store to be looked at and fixed. There is nothing you can do to fix it. It is a hardware problem. Either the screen has failed or the cable going from the logic board to the screen has failed. For both of those type failures only Apple, or a AARC, can fix it.

    If you are buying a new mac, Apple will do the migration for you, I would let them do it.
    If you have an external monitor, I would try to do a data backup before doing anything.
    Could also be your drive has already failed, or logic card.  Again I would take it the  Apple store, and have them deal with it since you bought a new Mac, they would do this for free, and the shoulder the responsibility.
    Hoe this helps.

  • TS1363 ipod is disabled how do i fix this problem?

    My ipod has been disable how do i fix this problem?

    You'll need to connect it to the iTunes library you normally sync it with and restore it.  If iTunes asks you for this passcode before it will let you proceed, connect the iPod to iTunes in recovery mode instead using the instructions in this Apple support document.

  • I dropped my iphone 3gs and the screen has gone blank now showing a white screen with no icons can anyone advise me how to fix it?

    I dropped my iphone 3gs and the screen has gone blank now showing a white screen with no icons can anyone advise me how to fix it?

    Tim is correct.
    But, first step with 3GS white screen and most iPhone problems is Reset, hold both home and power buttons until iPhone begins to restart itself, usually about 10 seconds of holding both buttons. If still white screen.
    Next step would be Restore the iPhone Firmware with iTunes on your computer. If still white screen.
    Next step would be to follow Tim's advice, if you had not already.

    Saji-
    Can you still access your Bookmarks at the top of the Safari screen?  If so, select it and choose History.  Then click Clear History at the top of the History window.
    If that does not help, double-click the Home button.  A row of recent Apps will line up along the bottom of the screen.  Scroll across and find Safari.  Press and hold on it until it starts to wiggle.  Then click on the red minus sign to remove it from the list.  Click the Home button to stop the wiggling and again to return to the Home screen.  Now see if Safari is working any better.
    If still no improvement, try resetting (rebooting) the iPad.  Hold both the Home and Sleep buttons for several seconds until the Apple logo appears.  Ignore the "Slide to power off" arrow.  The iPad will restart after a couple of minutes.  Resetting this way will not hurt anything, and sometimes clears up mysterious problems.
