When I start up my 15 inch Macbook pro, it gets to the apple logo screen with the spinning gear underneath and it just stays there and does not startup.  I have let it sit that way for up to an hour and it juts stays on that screen.  Please help!

Have you tried starting in safe mode?  What about using the recovery partition?  WHat have you tried so far, and what were the results?

    Here is the Apple support article that addresses that symptom:

    Ciao.

    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 boot failure is to secure your 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 your last backup, you can skip this step.
       
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
        
    a. Boot into 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.”

    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot 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.

    c. 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

    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot 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.

    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.

    Step 3

     

    Boot in safe mode. 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. Post for further instructions.

      

    Safe mode is much slower to boot 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 your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

       

    When you boot 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, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.

     

    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot 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 reboot as usual (i.e., not in safe mode.)

     

    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.

     

    Step 4

     

    Sometimes a boot failure can be resolved by resetting the NVRAM.

     

    Step 5

     

    Launch Disk Utility in Recovery mode (see Step 1.) Select your 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 reboot as usual.

     

    Step 6

     

    Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.

     

    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

     

    Step 7

     

    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.

      

    Step 8

      

    A dead logic-board battery in a Mac Pro can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.

      

    Step 9

      

    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

    Thanks linc Davis for your post of advice! It helped me bring my MacBook which is only 10 months old out of this issue. :-)

     

    saved me a lot of time and a headache from happening, after following the directions on your post the MacBook is as good as new!

    Hello!

     

    This may be a bit off. MBP 2010, stuck at loading screen with spinning gear. It doesn't recognize any keyboard taps. Can't go into safe mode or load from an external drive with Recovery on it.

    None of the above tips helped me.

     

    Thanks for eventual help.

    Re: Karlfromswe, same here (2010 MBP). Was doing the Mavericks update up until the point where a dialogue box said to restart to install the software, and the computer never powered back on. Hit the power button, and it then powered on to the gray screen with spinning wheel. No keyboard clicks or power button has any effect.

  • historyofmyworld Level 1 Level 1

    I'm experiencing the exact same issue. Updated last night after notification, and when I powered on my MBP this morning, all I get is the spinning. Can't enter safe mode or anything. No commands have any affect. None of the actions regarding the grey screen works.

  • parkeeet Level 1 Level 1

    I was eventually able to get my computer "fixed." Here's what I did.

     

    1. Eventually, the power button began responding and I was able to get the computer to turn off.

    2. I attempted to start up the computer in safe mode by holding down the "shift" key; this allowed the Mavericks installer to continue its installation, but just as happened the first time, the power to the computer suddenly turned off during installation (about 20 minutes into the install).

    3. I tried resetting the SMC to no avail; I tried resetting the NVRAM/PRAM to no avail. (please see this resource for a list of startup key combinations: http://support.apple.com/kb/ht1533)

    4. I started up the computer holding the "option" key to enable "Startup Manager" and select my boot volume. From here, I had a number of options

          -I selected the Mavericks installer as the start-up disk, but again, this didn't work.

         -I also tried to start up from the "Macintosh HD," to no avail.

         -I selected startup from "Recovery HD," and from here used the "Mac OS X Utilities"

    4a. From "Mac OS X Utilities," I tried using the "Disk Utility" to repair the disk, but I was unable to repair the disk.

    4b. From "Mac OS X Utilities," I then tried the option "Reinstall Mac OS X," but this failed because the installer couldn't find an eligible hard drive on which to install the OS

    4c. From "Mac OS X Utilities," I clicked on "Restore From Time Machine Backup." This would have been a viable option for me, but I hadn't backed up my files in 11 months, so I would lose lots of data and work. This left one option.

    4d. From "Mac OS X Utilities," I clicked on "Disk Utility," and clicked on "New Image" from the top toolbar; I used this to make a current copy of my hard drive, which I saved on an external hard drive. I then erased the hard drive, and this enabled me to reinstall Mac OS X and eventually restore all the data to my computer.

     

    In the future, I will be using Time Machine regularly to back up data.

    We have slightly different issues here. I'm stuck on loading screen the day after the latest Maverick update. It seems you were experiencing issues with installing the Maverick upgrade.

    I think I'm having the same issue. Did you find any solution?

  • imtxl Level 1 Level 1

    same thing happened to my brother's macbook, he did an update and now it's stuck at the grey screen.  I pulled his internal HDD and booted from the USB ( Now External) and it works booting up as an External HDD...something got eff'd up.

  • kolis Level 1 Level 1

    I had the same problem, and now I know what the problem was. The internet connection was down, or more specifically, the DNS was down. I connect using WiFi. Now internet came back and I was able to boot again. But it horrifies me to think that my computer wont start without internet. This needs to be fixed!

  • IanAlectzys Level 1 Level 1

    I just experienced the same problem tonight, i tried resetting the PRAM and it didn't help, safe mode never loaded, it just remained stuck at the Apple logo, and the weird thing is, when i try to go into recovery mode, it asks me to pick a language instead, just like when you first install the software and have to set up the configuration, i really don't know what just happened, it was fine just half an hour ago, it was running slow though, and so i restarted by holding the power button, and after that i just can't get it to start up.
