  • Why does my macbook screen keep crashing?

    Ok, so i dual booted (through boot camp) windows 7 64bit, but now it seems when i close the laptop shut, or sometime just waking it up from hibernation, (sometimes not all the time) the screen will come up pure white with flickering yellow splotches, im not quite sure how to describe the problem cause ive never seen anything like it before. There is no way to navigate the screen and it never return to normal, the only solution i found is to hold the power button until it shuts off then turn it back on.
    Has anyone had this issue? Please help i need to know if i should send my comp to apple!

  • Why does my macbook screen saver clock always read the same hour?

    Clock always reads 7 pm but the minute matches the current minute

    A lot of goofy things can happen if you have changed certain preferences, or upgraded with non-standard settings in place:
    System Preferences > Languages & Texts > Formats ...
    ... set a plausible standard form, like US or UK or something familiar. Close the window and Save changes. Then set to your actual preferences. Close the window and Save changes again. Test.

  • Why does my MacBook Pro and Mac Pro keep freezing?

    Why does my MacBook Pro freeze?
    MacBook Pro
    2.4 GHz intel Core2 Duo
    4BB 1067 MHz DDR3
    OSX 10.6.8 Snow Leopard
    I turned it on and I went to safari to look things up. Safari froze and then the whole thing became unresponsive - the mouse could move the cursor but it couldn't open any programmes.
    Tried safe boot several times. No help.
    Tried to repair disc permissions. The first time it got a little way then said 'user stopped repair' or something  - though I didn't touch it. Tried again it got all the way through and said 'repairs complete'. But no help.
    Couldn't clear cache etc as couldn't get to the relevant part to do it.
    Opened in single user mode. Ran the fsck -fy thing twice. First time it said both “The volume appears to be OK” AND “FILE SYSTEM WAS MODIFIED.” In 2nd run it just said  “The volume appears to be OK”. No help.
    Booted it up from the Superduper bootable backup version on a USB external drive. It seemed to boot up ok but then tried to click on something and the same thing happened - spinning beach ball and it just hung.
    Erased hard drive and reinstalled snow leopard but it just does the same thing. Suggesting a hardware issue not software but...the Eerie thing is, we tried backup version on boyfriends Mac Pro and it worked fine on there but 24hrs later his Mac Pro has got exactly the same screen freezing, unresponsive issue. Could this suggest there's something evil lurking on my back up? Can't get an appointment at Genius Bar until next week and need to get some work done, so hoping someone might have some ideas?
    Cheers

    ... does Apple products work much better with using Apple routers?
    While a genuine Apple router is likely to result in success, the reason for having one instead of another product is that it eliminates a lot of uncertainty. For example, we do not know the model D-Link product you have so no one is in position to speculate what the problem might be. Also, it makes support on this forum easier since there are only three AirPort models to choose from and they all work more or less the same.
    Generally speaking your iPods, iPads, MacBooks, and AppleTV ought to work with any router though, provided it is fairly recent and meets accepted industry standards. If in doubt you can purchase an AirPort Base Station, which comes with 90 days of free telephone support. If it does not result in any improvement for you, you can always return it for a complete refund. The return period is 14 days and be sure to keep all material - receipt, box, manuals, etc...
    If you elect this option be sure to follow its installation instructions, the most important of which is to power down your modem prior to connecting the AirPort Extreme, Express, or Time Capsule. All your other equipment will need their network settings adjusted to "forget" the D-Link network and connect to the new one.

  • Why does my macbook pro retina display shutdown while entering the administer account

    why does my macbook pro retina display shutdown while entering the administer account

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. 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. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and  Wi-Fi on certain iMacs. The next normal boot 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, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Why does my macbook pro stop loading the webpage every time i try to access netflix or youtube?

    Why does my macbook pro stop loading the webpage (in safari) every time I try to access netflix or youtube?

    Back up all data before proceeding.
    This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
    Step 1
    If you have more than one user, and the one in question is not an administrator, then go to Step 2.
    Triple-click anywhere in the following line on this page to select it:
    sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
    You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
    Step 2 (optional)
    Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
    Start up in Recovery mode. When the OS X Utilities screen appears, select
              Utilities ▹ Terminal
    from the menu bar. A Terminal window will open. In that window, type this:
    res
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window will open. You’re not going to reset a password.
    Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Under Reset Home Directory Permissions and ACLs, click the Reset button.
    Select
               ▹ Restart
    from the menu bar.

  • Why does my MacBook Pro make background music and video quieter when I am on FaceTime?

    Why does my MacBook Pro make background music and video quieter when I am on FaceTime? When my girlfriend and I are trying to watch a movie on Netflix together while on FaceTime my MacBook Pro always decreases the volume of any background sound on my computer so I can barely hear it. Is there a way to fix this? Thank you!

    Have the same issue too. Apple can you please change this annoying feature. You are making long distance relationships more difficult.
    I like how Facetime was with the old iOS, where nothing was dimmed. OR at least maybe if you could give users the option to turn on or off dimming of facetime.

  • Why does my macbook pro "goes to sleep" when charging?

    Why does my macbook pro "goes to sleep" when charging? It is working fine without charging but once I attach the charger to my laptop, it just blacks out or goes to sleep mode and I can't wake it up unless I unpluck the charger.
    I read from threads that it is a logic board problem....How do I solve this problem?

    Try an SMC reset. Follow the method for "a battery you should not remove yourself."

  • Why does my Macbook Air make a single buzz/beep?

    Why does my Macbook Air make a single buzz/beep every time I open it or turn it on? It doesn't happen after again after the initial buzz. If I open it after it has been sleeping, it starts up and then there is a buzz. This has only happened since I downloaded iOS Maverick.

    Beeps on startup:
    1 beep = no RAM installed
    2 beeps = incompatible RAM types
    3 beeps = no good banks
    4 beeps = no good boot images.
    5 beeps = processor is not usable

  • Why does my macbook pro get hot

    Why does my Macbook pro get hot while I am only on my email account?  This is a recent change.  It gets too hot too put in my lap.  Is it a battery issue.

    Open Activity Monitor in the Utilities folder.  Select All Processes from the Processes dropdown menu.  Click twice on the CPU% column header to display in descending order.  If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar.  Click on the Force Quit button to kill the process.  See if that helps.  Be sure to note the name of the runaway process so you can track down the cause of the problem.
