My macbook pro will not get past the gray screen with the apple logo and a loading bar.

My macbook pro will not get past the grey screen with the apple logo after attempting to load for hours. I have already tried resetting the NVRAM/PRAM and a couple other tricks and no luck. Anyone out there have suggestions for my problem? Help would be much appreciated since i use my computer for everything at school and i am in desperate need to get this baby working again.

You didn't say which OS in your tag, but maybe you might find something here.

My Macbook Pro will not shut down, restart or sleep, with either Apple Logo at the top or the power button.

Hi, I have a 13" Macbook Pro with Mountain Lion, and I've had it for less than six months.
It has worked perfectly ever since I got it and I have been completely happy with it, until today. My computer's had a variety of problems; The screen has turned black three times now in the middle of me using it (actively typing or using the touch pad). After clicking some keys or swiping the touchpad, it comes back, but I cannot figure out why this is happening. The big problem, however, is that it won't shutdown.
I usually shut my computer down at night, and I was trying to today, but it just didn't work. I have tried shutting down by pressing the power button; no dialogue or question box comes up. I have tried shutting down from the Apple Logo at the top left of the screen; nothing happened. My computer won't sleep, restart or shutdown at all. When I close the screen, it goes darkens and lights up as usual, but it won't shut down! What's more, none of the options in the Apple Logo will work; for this post, I tried to see the About This Mac screen, and nothing happens. At best, the Rainbow Disc of Pain will appear and then just go away. The menu does pop up though when I click on it, my Wi-Fi is fine, the apps work, the keyboard's fine, the touchpad is great, everything works but that.
I have tried Command+Tab to see open applications; I have shut them all down till only Finder is left. I have tried click Force Quit, of course, nothing happened. Nothing at all, not even a dialogue box. I have tried emptying my trash, along with all the 'sketchy' applications. I have plugged my computer in, just in case. Nothing has made any difference and I am very worried!
I love my macbook pro, and have up to this point, but now I am extremely worried about it; all my important files are on it, and I have nothing to back up with.
Please, please, please, please help!
FYI; I have avast! Virus Database. I cannot imagine that that would cause a problem. Please help me!!!

Yay! Solved my own question; just did a hard shutdown, worked like a charm! Funny, didn't before. But who am I to question salvation?

TS2570 tried restart and hold c key, but still only getting white screen with grey apple logo and spinning loading icon, what do I do next?

nephew had mutliple tabs open and shut down the iMac by hitting the button on the back instead of closing everything corectly. Now the only screen i get is the white with apple logo and the loading circle icon. i have attempted restart and c key with disk in but cant even get a menu to come up. What can I attempt from home before having to haul this into the store?

wireless keyboard and mouse were working prior to safe mode attempt, i was able to eject disk. still waiting on the safe mode restart. I'm not sure what I should be looking for to confirm safe mode and what the screen should look like if successfully processing. it seems to be putting off a lot of heat. BRB

MacBook Pro will not power up beyond gray screen and spinning circle.

Hi all,
Everything was fine earlier, but later went to turn on my MacBook Pro (OS X 10.5.6) and here's what happened:
- Apple start up "gong" sounds
- Screen lights up gray with dark gray Apple logo in center
- 12 segment gray circle rotates
This goes on for about a minute or so and never advance to beyond to blue screen, login window, etc., the screen just goes black and shuts down after that. I since tried powering it up about a dozen times and the same sequence of events happen with no complete start up.
Battery is fully charged and 110VAC power supply is plugged in.
Anyone have any ideas that might help? Please let me know if I didn't provide enough info.
Thanks in advance.

You'll have to do the following if possible:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

HT1338 MacBook pro will not update past 10.5.8

What can I do if my MacBook pro will not update past OS X 10.5.8
When I check for software updates, it says there are no updates and it is up to date.

OS X 10.5.8 is the last update for that version. If you need to go to a OS X 10.6 then you are going to have to purchased a DVD for the upgrade.

What model MBP and which version of OS X? Sounds as if the hard drive may have failed. If you have an installation disc, try booting with it. If your machine came with Lion or Mountain Lion, try booting to the Recovery partition - Command and R keys held down while booting.

If the normal restart doesn't work, and you restart on the recovery hard drive, from the choices of things to do window that appears, select Terminal, and in the Terminal window type: resetpassword and then press enter. You will have a window with the users to choose from to reset the password. Select the one you want and you will be able to reset the password, double entry of course.

My MacBook Air can't get past the gray screen with the apple logo. What's the fix?

My MacBook Air can't get past the gray screen with the Apple logo, so I can't login. Does anyone know the fix for this?

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 Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
How to back up and restore your files
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 by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
How to use and troubleshoot FireWire target disk mode
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.
Before reconnecting 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.* The instructions provided by Apple are as follows:
Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
When you see the gray Apple logo, release the shift key.
If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
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.
*Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
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, 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 above for instructions.) 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 produces. Look for the line "Permissions repaired successfully" 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
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.

Macbook pro will not boot even to grey screen ??

my macbook pro will not boot even to grey screen ?? Just stopped wprking after I closed the cover.

What other indications are there, does the white light turn on, solid or pulsing?, do you hear the startup chime, or bong if you prefer. Can you hear the drive, the fans?

IMac will not get past chime & white screen

iMac will not get past chime & white screen. I have tried all the start up key combinations I can think of (d or c etc) with a start up disc, but no joy. The disc drives seems ok - you can hear it working & it will eject OK.
Any other start up ideas, please?

Have you tried a safe boot? If not, hears how (it's straight from Mac Help):
To start up into Safe Mode (to "Safe Boot"), do this:
Be sure the computer is shut down.
Press the power button.
Immediately after you hear the startup tone, press and hold the Shift key.
Tip: The Shift key should be held as soon as possible after the startup tone but not before.
Release the Shift key when you see the gray Apple and progress indicator (looks like a spinning gear).
During the startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
During the startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

We can't help you if you don't even know what you are installing. Never install anything if you do not know what it is. Installings through Software Update always have explanations which you should be reading to see if you actually need and/or want them.
That being said, it appears you attempted to upgrade to Mavarick. Although I am not positive.
Sorry, I am going to back out of this because I nor you know what it was you installed. Hopefully, someone else will chime in here.
GOOD LUCK!
