  • 2010 MacBook wont boot past grey screen, even after a new hard drive and install CD.

    Hey guys, I received a 2010 Macbook last year as a gift (no warranty). It worked fine untill a few days ago. It wouldn't boot past the grey apple logo. I took it in to an Apple store and they said it was a bad HDD. Since I didn't have much stored on it, and I have everything backed up to my desktop, I got a new, larger capacity HDD and replaced it with no issues. I started the Macbook with the OSX Leopard install CD, but it didn't identify the HDD, and now it won't boot past the grey screen.
    Any ideas? Is it the motherboard?
    Thanks a lot!

  • TS2570 macbook air : start with grey screen... help !!!

    I have a new macbook air (3 months old) and all the sudden when I start it I have a grey screen with a question mark. The relevant Apple support page doesn't take into consideration the fact that you can't put an install disk into a macbook air. Help !

    Thank you for your answer.
    Unfortunately, I had already tried this online recovery (it also works if you boot holding the option) but the utility program didn't offer me the possibility to repair (when I selected the disk, this option wasn't available. In fact, I couldn't choose any option at all for my disk).
    I had just done the last system update proposed by Apple today. I never had any problem with a mac before and I am really in trouble in my work because of that. How can I try to save the most important files I was working on ? I am in Brazil so there is no Apple store available near my house.
    I also have external hard disk, an imac and a macbook but I don't know if I can use any of them for that...

  • Macbook wont go past grey screen with spinning cog below...HELP!

    PLEASE, PLEASE....could someone advise urgently, was using machine ok, left it for a few mins & it went to sleep...then I couldn't log back in. Restarted and now can't get past this grey screen....have tried all recommendations...tried re install and says it can't. Tried the fsck...it say's "volume check failed". Tried the disk check...it said there was no problem. I am in Spain (Palma) and about to set off acrosss the Atlanntic to S.Maarten...my warranty expires in April and I am unlikely to be anywhere with a mac dealer or authorised service place in the next 6 months...my life is on this machine!! PLEASE HELP????

    What happens if you boot from your system install disk and run Disk Utility? Does the utility see the drive and can you verify/repair the drive?

  • OS X wont start just grey screen

    I was on my mom's computer(same model and OS as mine) setting up her new ipod. I was prompted to update the ipod software and did so. I believe the update was successful but afterwards the computer froze, and i tried to force quit itunes. This did not work so i held down the power button and turned the computer off. Then i turned it back on and it only comes to the grey screen with the apple logo. I have tried the following in this order:
    -reset PRAM
    -boot in Safe mode(holding shift key)
    -insert install disk and repair permissions
    none have produced any results.
    thanks in advance

    Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk.
    You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.

  • Ok.. macbook wont go past grey screen.

    ok so i was normally using my macbook(despite its shutdowns, ive been using it with the shutdown problem for a while now..)
    anyway, it all began with my USB ports// my macbook wouldn;t recognize anything.
    then i tried playing a DVD.. my macbook asked me what i wanted to do wit the BLANK cd. (um, it wasnt blank!! it was a movie)
    so i decided to restart, and viola. screwed!!!
    now my macbook is stuck on the start up screen. it wont go beyond the apple+scrolling sign. thats all it stays at. so i put in my installation CD 1, and restarted it with the C button pressed.. ran disk utility and it shows there is nothing wrong ( verified and no repair needed to disk)
    i removed the installation CD and tried restarting. nothing. it stays on the start up screen...
    help anybody? week 20 macbook.. going to call apple on friday, coz i get back to town on thursday night. someone tell me wat to do. plz..
    thx

    Okay, since booting to safe mode didn't seem to work try booting to the install disk one.
    To do this put the disk in the computer when it is turned on. Next shut the computer down (hold down the power key until it turns off). Then turn the computer on and hold down C key until you are asked to select your main language. (I am going to assume English.) After selecting the language press the arrow. The installer will load, don't proceed with the installer. Instead wait for the top menu bar to appear. Select "Utility," then Disk utility. In disk utility select the Mac HD. Then make sure that the First Aid tab is selected. Press the "verify disk" if there are any errors click "repair disk". If the errors are not repaired the first time around try repairing once more. Once it is repaired double check by clicking verify disk.
    Here is an article with some possible error messages
    http://docs.info.apple.com/article.html?artnum=302672
    To get out of the install disk quit disk utilty then go to installer by the blue apple, go to the Installer Menu and then quit installer and then restart.
    Doing the above will in the very least save you some time on the phone with Apple. If you can't repair the disk with disk utility write down any errors and let Apple know.
    I hope this helps.
    p.s. the steps in the article in my previous steps do also apply to 10.4

    AND MORE TOO MUCH TO COPY N PASTE HELP PLEASE!!!!!

    Reset the PRAM
    Reinstall the operating system from the dvd (you will not loose your data)

  • 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.

  • My macbook wont start. it just comes to a black screen that sais no bootable device.  -asian gal

    My macbook wont start. it just comes to a black screen that sais no bootable device. 

    Ok then either the drive has failed or the cable from the drive to the logic board has failed or the drive is so corrupted that the computer doesn't see the OS on it.
    Boot the computer from the original install DVD that came with your system. If your system is new and came with Lion then at startup hold down the Command+r keys and that will either boot you to the built in Recovery HD or to the internet recovery system. From either of those you can check the drive for error and or see if the computer even knows there is a drive in the system.

  • Brand new OS X Mountain Lion starts in grey screen login window doesn't know me verify passwords all jacked up says to get external hard drive recovery so I have to spend more moneyon my brand new computer or can I fix and safe boot

    brand new OS X Mountain Lion  Bought in November 2012 starts in grey screen login window doesn't know me, went to utility dIsk ,verify passwords all jacked up, I Engaged repair passwords then press verified Macintosh HD it said Macintosh HD is OK but repair disk button was still lit up and wanted me to make a recovery disk external hard drive and such,please tell me I can fix in safe boot..

    The repair button is always clickable when you are on your Recovery partition, it's nothing to worry about.  Do this instead.
    Then start in single user mode (Command-S)
    Type fsck -fy to check your disk first (it wont let you start working on a disk until you have checked it)
    Then type mount -uw / (dont forget the slash) to mount your Macintosh HDD
    Then type passwd username with username being the username of your admin account
    It will make you type the new password twice afterwards. From then you can boot into OSX as normal and use that account to fix the rest of your passwords.

    Not saying you have to reinstall...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."

    There indeed may be something wrong with it, but we're just other users here... have you tried Apple Hardware Test? (Holding the d key down while booting from the Install Disc).

  • Macbook wont start and makes ticking noise

    The subject line says it all. My macbook wont start and it makes clicking noises from inside the case, kind of like a watch. The display turns on and the chime goes when it starts, but the screen stays white and nothing happens.

    You can run diagnostics from the OSX disc. Insert disc one and while it is booting hold down the d key. This should take you into diagnostics.
    You might also try to reset PRAM AND PMU first.

    It acts as our server and the raid drive on it had been having privileges problems. One person on another forum suggested I run Disc Utility to repair permissions. I did so, there were a couple of minor permissions fixed. After that, the Mac would not re-boot.
    I got the DVD door open and ran Disk Warrior on the drive, the files and the hardware. It claimed to repair a few minor issues and there were no problems with the hardware. It still wouldn't boot, so I reset the SMU. ?Still no start, so I reset the PRAM. Still the same.
    Any ideas?
    G5, OSX 10.5.6, 6 GB ram, approximately 100 GB free on system drive, over 800 GB free on RAID.

    I'm having the same problem though I'm running 10.4.11. After getting to about the point you are at did an "Archive and Install" but after about a day of working fine, it had a kernal panic and I couldn't boot past the gray screen again. I took it to my local Apple Store and they ran 2 hours of diagnostics w/o finding anything wrong. They told me to do an "Erase and Install." That is where I am at now because I can't get the machine to boot from my 10.3.5 Install CD--it hangs at the black screen when I try to boot from the CD by holding down "C" at boot. This is the original system software that came with the machine at purchase.
    There are many posts out there about bad RAM causing these kinds of problems. You might want to search around for those posts.
    Good luck and I'm going to watch this thread hoping that someone will have a suggestion that will help me too.
