HT204347 MY COMPUTER IS LOCKED UP WHAT KEYS DO I PUSH AT START UP TO FORCE THE OS TO WORK?

MY COMPUTER IS LOCKED UP WHAT KEYS DO I PUSH AT START UP TO FORCE THE OS TO WORK?

brittneydoyen,
you can try this: boot your MacBook Pro into Recovery mode by holding down a Command key and the R key as it starts up. Once the OS X Utilities menu appears, select Disk Utility. On the left-hand side of the Disk Utility window, select your internal disk’s boot partition (typically called “Macintosh HD”). On the right-hand side, press the Verify Disk button if it’s not greyed out; if it is greyed out, or if it reports that errors were found, press the Repair Disk button. Once the verification/repair is completed, exit Disk Utility and select Restart from the Apple menu to restart in normal mode. Is it able to get to the login screen now?

  • My iPhone 4s was stolen this weekend and I did the Remote Lock.  What exactly does that do?  Also, if i do the Remote Wipe will that erase all of my data and impede anyone from ever using the phone?

    My iPhone 4s was stolen this weekend and I did the Remote Lock.  What exactly does that do?  Also, if i do the Remote Wipe will that erase all of my data and impede anyone from ever using the phone?

    The remote lock locks the iphone with a passcode that you set. By remote wiping the device it will simply restore it and clear it of all its data, but by doing this it will prevent you tracking it and communicating with it (e.g. remote locking it) in the future

  • I have the iPad 2 (verizon). The lock rotation is always on (can't change it) and NONE of the sound effects work.

    Since yesterday evening, the lock rotation icon is stuck on, and none of the sound effects work. I have factory restored and restored from a backup twice, same result. And I'v checked the headphone jack.
    Am I missing something?
    THNX

    Assuming that you havn't turned the volume completely down, then have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
    Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar (and similarly for rotation lock) : double-click the home button; slide from the left; and it's the icon; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

  • "Track who downloaded what, when," however Adobe deleted all tracking data when forcing the move from SendNow to Send

    I have transcripts from chats with two different Adobe employees (June 2014 and September 2014) who promised that Adobe had retained the tracking data (not the files). They said that the tracking data would not be available to users at the time of the transition from Send to SendNow, however both promised that eventually the data would be migrated from a SendNow account to the new Send account.
    Adobe sold us all on being able to "Track who downloaded what, when." Were we instead sold a bill of goods?
    Am desperate for an answer.

  • Opening PDF files causes computer to lock up

    Whenever I click on any PDF attachment or file, there appears a screen with a heading "ai.icns…" that seems to be trying to open the file and the cursor just goes round and round as though it is locked up.  I cannot close this screen and have to force the computer to quit. It is possible, however, to run other programs.  It's just that the screen I described will not quit.

    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
    Please take this step regardless of the results of Step 1.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
    Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
    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.
    Test while in safe mode. Same problem?
    After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

  • My ipod (nano, 6th generation) won't sync to a new computer with different stuff on it. It *appears* to sync but when it's done it still has the stuff from the other computer on it. What to do?

    My ipod (nano, 6th generation) won't sync to a new computer with different stuff on it. Itunes on the new computer doesn't give the usual warning that you are about to lose all your existing stuff and the ipod *appears* to sync but when it's done it still has the stuff from the other computer on it.

    Set computer to lock with password in 5 seconds. now cannot open in time because of the 5 second shutdown. What can I do to now get into my computer??

    I'm not sure which option you set.  Requiring the password after 5 seconds in System Preferences > Security only kicks in after the sleep or screen saver.  The smallest option for sleep or screen saver is 1 minute.
    Which options did you set?

  • HT1338 Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.

    Occasionally my caps lock key blinks some time later my keyboard locks up what is causing the blinking and is it related to my keyboard locking.
    This blinking occurs when no keyboarding is going on.
    Back-up is not running.
    I am on-line.

    Anthony:
    The normal practice is to use the Shift key when typing a single Capital letter, as in a name or the beginning of a sentence, and the Caps Lock key to type all caps. The easiest thing would be for you to retrain your little finger to use the Shift instead of Caps Lock. I know of no way to display an icon at the bottom of the monitor to display that the caps lock key is engaged.
