    Macbook Pro 2008. My screen stayed black and is unresponsive and sleep light is on. I shut down and then restarted and nothing happened on screen but sleep light came on and is solid.

    It could possibly be the video card, or the logic  board.  You could try a smc reset if you have not done s yet.   smc reset:

    I had an issue similar to this, and there was a bad logic board, hard drive and video card.
    You might want to bring it in to the Apple store, they do the diagnostic for free and give you a repair price.
    They offer a flat repair rate, which they fix what ever is wrong as long it was due to liquid damage.
    The repair cost me about 1/3rd the price of a new machine and the machine has been fine ever since.
    It's worth getting it checked out.

  • Macbook Pro suddenly shuts off. screen goes black and won't turn off till after a few hours.

    Hi everyone!
    So I've had this problem from my macbook since months ago. It sometimes just shuts off by itself, the screen turning black and won't turn on until like after a few hours (sometimes a day, but sometimes you could also immediately open it just like that.)
    When it shuts off and you plug the adapter it is still charging, the lights on the side of the macbook book still lights up just fine if you press the button on the side. the only problem is that it wont open until after a few minutes, hours or days (very unpredictable) (also tapping the macbook helps, I dont know if it "really" helps or not, but it works sometimes.) But when it open it will be working fine until another couple of weeks or 3 or a month (again unpredictable)
    I dont know what's wrong with my laptop, please help me. It would be greatly appreciated! thank you so much in advance!

    Hold the power button down for 10+ seconds.  Then bring the MBP to an Apple store for an evaluation.
    Ciao.

    Take it in for service. Your screen probably needs to be replaced.

  • How can I set up Cinema Display as a main screen and leave my macbook pro as a second screen instead?

    How can I set up Cinema Display as a main screen and leave my macbook pro as a second screen instead?

    I learned that the Dock is positioned at the chosen edge of whatever Display is positioned farthest to that side.  E.g. for the Dock to be positioned on the right side of the Cinema Display (instead of the right side of the MacBook), the Cinema Display must be oriented (by dragging) to the right of the MacBook monitor on the "Arrangement" tab of the Displays Preference Panel.

    Was this a dark gray screen that appeared with the message to restart the computer in five different languages? If so that's a kernel panic. It would help if you can post the panic log: Mac OS X- How to log a kernel panic. Also visit The XLab FAQs and read the FAQ on diagnosing kernel panics.

  • TS4088 MacBook Pro (15-inch, Mid 2012): Intermittent black screen

    My new MacBook Pro is running Mountain Lion and the screen suddenly goes black while I am working. It seems that the machine is running, but the screen just goes black and does not show the login box or anything else.
    In order to get back to the login, I either have to restart it, or close the machine and open it again.
    This seems to be the same problem reported for the MacBook Pro 2010-2011.

    Any idea on what is going on??

    I too have started having this problem. I am running OSX 10.9.4. Has anyone gotten any answers to why this may be happening? This issue just recently started. I can't say it was caused by any recent update.

  • My macbook pro went from startup screen to grey vertical stripes

    my macbook pro went from startup screen to grey vertical stripes with a bit of flashing.  Force quit twice and it is still doing it.  Had a bit of problem last time I started it with flashing screen, but it settled.  After leaving it on screen went black (as usual) and on waking had desktop up but continued to flash.  Any suggestions?

  • Macbook pro boots to white screen and a ?

    macbook pro boots to white screen and a ?

    Gus@MaggiesFarm,
    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 Mac 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. Does it get past the white screen now?

  • Is it possible to remote-access my MacBook Pro away from home?

    Is it possible to remote-access my MacBook Pro away from home?
    What I currently have:
    Late-2011 MacBook Pro 8,2 (OSX Mavericks 10.9.5)
    2.5ghz Intel i7 quad-core
    16gb RAM, 1024gb SSD raid-0 (internal)
    Connecting to the internet through:
    Apple Time Capsule 2TB (via ethernet)
    +
    Time Warner Cable "Ultimate 100" (top speed)
    I would basically like to be able to have my MacBook Pro on *at home* and connected to the internet via ethernet to the Apple Time Capsule.. and then be able to somehow connect and log in to my MacBook Pro, either through another computer or preferably, my iPhone 5s..
    Mostly just interested in having accessibility to be able to make downloads, such as magnet links, while away from the computer.. and basically be able to come home to mostly finished or complete downloads.. Basically like how you can DVR/TiVo things from your iPhone and have it sync with your DVR/TiVo while away from home..
    Is this possible? Thank you!!

    Yes you can do this.
    I would suggest you start with TeamViewer.com (free for personal use).
    You will need to install TeamViewer on your Mac AND your iPhone.
    The Mac version will need to be configured for unattended remote access.  You should practice before you leave the home.
    There are other iPhone apps that can remotely access a Mac.  A lot depends on whether they can get past the home NAT router.  Be careful of apps that provide VNC access, but do not provide a way to get past the home router.  If you try one of these, make sure you test it away from your home WiFi network.

    You can have Apple replace the logic board, but it will be at your expense.  The free replacement program has ended.

  • 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.
