  • HT1349 My Apple MacBook Pro won't start up.  It is stuck on grey screen and I reset all of the stuff.  It still won't work also half the screen goes dark then you have to shake it till it goes back on.  Please help.

    You might have better luck posting on the Mabook Pro discussion forum, as this is the OS X Xserve server forum.
    Have you tried booting it from a DVD? If so and you find the same result, then its probably a hardware issue.

  • My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

    My Macbook Pro won't start up. All I get is a grey screen showing a grey folder bearing a question mark. Help please!

    The folder with the question mark indicates that the machine is unable to find a bootable volume on startup. This is typically caused by one of three things:
    1.) The internal HD has failed or is failing and needs to be replaced
    2.) There is significant directory damage to the volume that requires repairing in order to boot
    3.) Some other internal component failure between the HD and logic board
    I'd ranked them in the order that is most common (from my personal experience). Boot to the OS X Recovery tool and attempt to repair the startup volume. If that fails or the drive is not detected it's usually a tell tale sign of a failed HD.

  • My MacBook Pro will not start up.  I only get a grey screen with the spinning wheel.  No blue page appears and the grey screen remains.  Tried starting with the Shift key but ineffective as well.

    Can't get my MacBook Pro to start up.  Have shut it down several times and tried restarting but all I get is a grey screen with the spinning icon.  Apple Support online suggested starting with power button followed immediately with the shift key.  Same results.  Also tried power button with shift key, command, and V.  Black screen appeared instead with lots of data language but still no starting.  This final page was suppose to result in an internal system check and restart but nothing happened and the black screen remains.Where do I go from here?  Scheduled for the Genius Bar tomorrow but would like to resolve this beforehand.

    You may be having a hardware problem that you cannot resolve on your own. Nevertheless...
    ...hold down the command and R keys whilst booting to try to get to your Recovery partition. If you can, use Disk Utility to try to Verify your boot drive (usually named "Macintosh HD" unless you've renamed it). If the verification fails, try to repair your hard drive. If everything appears to be OK, restart.
    If you can't get into your Recovery partition, your problem is likely hardware related. If so, keep your appointment and see what the Apple techs have to say.

  • Macbook Pro won't start up at all!

    Help anybody!
    So my macbook will not start up again. I believe my computer is in some sort of sleep mode, because i did not turn it off..
    When plugged in to the adapter I can see the power adapter light up. When I press on the caps lock key it lights up. The little light that indicates if my macbook is on/sleep mode, isn't flashing when close it's just straight light.
    I tried pressing random keys, i tried the power button. Nothing is working!
    SOMEONE HELP, or I'm seriously going to have a heart attack.

    Hold down the power button for 5-10 seconds. Then press the power button again
    Let me know if that fixes it.

  • My MacBook Pro won't start. Every time it has a white screen with a blinking folder in the middle with a question mark inside... What should I do?

    Thanks for any suggestions!

    There are four general causes of this issue:
    1. The computer's PRAM no longer contains a valid startup disk setting when there aren't any problems with the disk itself. This can be checked for by pressing the Option key and seeing if the drive appears.
    2. The internal drive's directory structure has become damaged. This requires usage of an alternate bootable system to perform the repair.
    3. Critical system files have been deleted. This requires usage of an alternate bootable system to reinstall them.
    4. The internal drive has died or become unplugged. This is the most likely case if the computer took a sharp impact or there are unusual sounds coming from its location.

  • Firefox won't start,but when I shut my computer down it says that it is running. What is the problem?

    Firefox will not open, but when I shut my computer down it says that it is running and must be forced quit. Once I rebute the computer it opens but is very slow and hang up on many web pages. I have reinstalled it with little help. In contrast, Windows Internet Explorer works fine.

    Did you check your security software (firewall)?<br />
    A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.<br />
    Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.<br />

  • I was messing around with .kext files in the MacintoshHD and now my MacBook Pro won't start up.

    I was messing around with .kext files in the MacintoshHD and moved the system.kext and two others to my desktop and deleted the originals and now the MacBook Pro won't start up. All I get at start up is the apple icon then a bunch of text shows up part of which says Mac OS version: not yet set. then the apple icon turns into the power icon and tells me to turn off the computer. I've tried reinstalling from the install DVD by holding down option when powering on and selecting the install DVD and it just goes to a white screen with the apple icon and stays like that. I didn't have the disk utility on my Mac before this happened because I deleted it to make room on my computer a while ago so I'm not sure if that's why it won't load the install DVD but anyone who knows the solution to this with out going to get it repaired would be greatly appreciated. Thank you!

    Never mind my dad just found the original install DVD and that worked. Before I was using an install disc that Apple sent me for another issue I was having, but thanks for replying so quickly and trying to help on this Thanksgiving day!!!

  • `my macBook Pro won't start up. Just get that gray blueshy kind of screen and don't go nowhere.

    My MacBook Pro won't start up. Just get that gray, blueishy screen and don't go on.

    Try a safe boot.

    This boot takes longer than a normal boot, be patient. If it boots login, and see if it seems normal. If so, logout and reboot normal.

  • Hi! My MacBook Pro won't start! HELP !!!

    Hi! My MacBook Pro won't start! I have tried everything I can think of like Safe Mode (doesn't work), Recovery (does not find Recovery Drive), Booting with OS Snow Leopard Cd (doesn't work)...
    I have really no clue about what to do now... I paid quite a lot of money for this computer and am pretty short of money nowadays! Would like to repair with help rather than having to take it to Apple Store.
    Has anyone had this same problem? 
    All I get is white screen + grey Apple and spinning grey disk...  it's 100% frustrating! Any help would be more than welcome since I think i've tried EVERY SUGGESTION on this Support Center and Youtube videos...
    This MBP is from 2011, runs on OS X 10.6.8
    I tried booting with OS X Snow Leopard CD, it didn't work!  (my cd player works! recognizes the Snow Leopard CD, but then never opens it... goes back forever to the with screen + apple and spinning disk)
    I don't care about the content, it's OK if i lose all DATA... I just want to bring this Mac BACK TO LIFE!
    When i run coomand on root# fsck -fy  --> RESULT = my HD was checked and seems to be FINE!
    Thanks

    Please make a Genius Appointment and take it in for service.

  • Spilled liquid on MacBook Pro - won't start - any suggestions?

    spilled liquid on MacBook Pro - won't start - any suggestions?

    Thank you both for your responses! I watched a video on how to remove the hard drive - special tork(?) screwdriver and too many steps for me to feel confident about doing it myself, so I took the computer to an Apple Store - and thank God, the hard drive appeared undamaged - they are transferring the data to a new Macbook Pro. The loss of data was the scariest part, so I am breathing again!
    The laptop was three years old, I was hoping for another year or so before upgrading, but such is life. I appreciate your upfront advice.

  • MacBook Pro won't start after changing access rights

    I did something very wrong. Unfortunately I changed the access rights of Macintosh HD for "everyone" to none.
    Result, my MacBook Pro won't start anymore.
    Already tried the installation disk, reset password for root and users. No result.
    Help program "check acces rigths". Didn't work either.
    How do I reset the access rights of Macintosh HD?

  • Macbook Pro won't start properly... keeps restarting without chime!

    Macbook Pro won't start properly... keeps restarting without chime!
    Late 2007 Macbook pro.  OS upgrade worked great for me.
    I have had this problem on and off for a month or so.  I simply cannot figure out what the issue is.  I have tried poerup with and without AC power and with/without battery installed.
    Starting in Safe mode does not help.
    Trying to start with a disk does not help.
    It sort of seems like it might be an internal power issue or GPU issue.
    It also feels sort of like a software compatibility issue since my Macbook Pro gets reallly slugish for no apparent reason sometimes and IU have to restart.
    I have three different anti-virus programs so I doubt it is a virus issue.
    I noticed all this start after I did a Mountain Lion upgrade and then tried to start up VMware Fusion.  Fusion seemed to just bog down the computer horribly but did not cause a system crash.
    I need to edit an important sequence on Final Cut Pro and don't want it to freeze me out!
    Anyone who has had this problem and resolved it please let me know 
    God bless

    Install or Reinstall Yosemite, Mavericks, Mountain Lion, or Lion from Scratch
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    How to Clean Install OS X Yosemite
    OS X Mavericks- Erase and reinstall OS X
    OS X Mountain Lion- Erase and reinstall OS X
    OS X Lion- Erase and reinstall Mac OS X
    Note: You will need an active Internet connection. I suggest using Ethernet if possible
                because it is three times faster than wireless.
