MacBook won't load past the white startup screen.

I'm going to start off by saying I'm a huge idiot.
My MacBook was being sluggish last night, so I (impatiently) force-turned it off. Whenever I turn it back on, I get stuck at the white screen for about 10 minutes and the Apple logo never loads. I must've made the harddrive corrupt by turning it off while it was doing some important background work.
Is there any way I can fix this? The data on there isn't important as I have my course work backed up, I just need it up and running for class tomorrow. Can I wipe the harddrive and do a clean install somehow?
Hopefully someone can help.
Edit: I managed to open Disc Utility with my Mac OS X 10.6 disc, and I can't even see my harddrive located anywhere.

Sorry for the double post, but I can no longer edit the main one.
I heard the most gut-wrenching sound when I held "Alt" to get to my partition, so I opened my MacBook up, removed the harddrive and reinserted it. I'm not sure if it was the harddrive that produced the noise, or the installation disc.
Now I can see my Harddrive located in Disk Utility

I'm given so many errors, but they all point to the same conclusion...
My Harddrive is fried and I need to look for a replacement. Could anyone point me in the right direction? My Macbook is really old I've even forgotten the type! It's a Black MacBook from around 2006 or 7 is my best guess. What harddrive would fit?

MacBook won't load past the gray apple screen, what do I do?

A few months ago my cat peed on my computer and despite the battery no longer working the computer its self continued working fine after letting it sit a few days.
A few weeks ago I accidentally unplugged it form the wall forcefully turning it off, when I tried to turn it back on it wouldn't go past the gray apple logo with the spinning pinwheel.
I've tried to troubleshooting it numerous times but even after letting it safe boot all night I came to no avail.
All the suggestions I've gotten on other sites say I sould re-install the OSX server, the problem being I don't know how, or which OSX I have, they also say the memory will probably be erased, I can't have this happen because I have many things I wrote on there that I have no where else. I bought this laptop in the first few days of 2009.
What do I do without erasing the memory?

Hello,
Could someone help me, please? I apologize for the long message but I want to be as detailed as possible.
My MacBook (purchased early 2006, white 13", upgraded to Leopard about a year ago with no problems until now) will not boot past the grey screen and spinning wheel.
Here' are the list of 6 steps I've followed so far and still is not working. Oh, and I do not have any peripherals attached to my MacBook:
1. Reboot in Safe Mode: tried pressing down the Shift key before the powering up sound AND after the sound. Could not get into Safe Mode. Did this several times, holding the Shift key for as much as a minute or two. Nothing but grey screen and spinning wheel.
2. Reset NVRAM/PRAM: CMDR+POption: Computer restarted but still goes into Grey Screen, spinning wheel and stays there forever.
3. CMD +S: I read this online. Gave me a black screen with a lot of information, but I don't know how to read the computer jargon, let alone know what to do with said info.
4. Disk Utility Repair Disk : Inserted my Leopard install disk. Went to Utility Disk. Performed a Repair Disk and I did get two error messages, something related to id 70000452 should be id 70000450 ( I'm sorry to say I cannot remember the exact error messages). But it showed as repaired. When I did a 2nd Repair Disk, I got the message that the volume appears to be OK. Turned off and on again, nothing but grey screen and wheel.
5. Disk Utility Repair Disk Permissions: got several error messages and this time some could not be repaired:
-Permissions differ on system/library/CoreServices/Front Row.app/Contents.... should be -rw-rw-r-- , they are lrw-rw-r--
I got this about 4 times.
-Permissions differ on System/Library/PrivateFrameworks/DiskManagement.framework/Versions/a/Resources/ DiskManagementTool has been modified and will not be repaired.
-Permissions differ on System/Library/PrivateFrameworks/DesktopServicesPriv.framework/Versions/A/Resou rces/Locum has been modified and will not be repaired.
-SIUD file has been modified and cannot be repaired also shows twice.
I've read that these messages can be ignored. Is this true? I verified permissions after that, rebooted and still the same grey screen and wheel.
6. FINALLY: I tried to hook a FireWire from my notebook to my sis, iMac, and see if my HD shows up on hers so I can try to copy and save my pics and music. I was then planning to Erase and Reinstall. But my HD doesn't show up. I turned off both Macs and turned on, pressing T on my Notebook so it acts as a drive, but nothing shows up on my sis iMac. What am I doing wrong here?
And if it cannot be repaired, what do I do?
I'm an amateur photographer and would like to save all my pics, as well as my iTunes music. Much of everything else is just docs, and I think I backed the docs up, but not iTunes or the pics lately (not enough memory available in my flash drive). It also means I do not have a lot of RAM available (I know, I should've bought an external hard drive :o) to perform an Archive and Install.
Can I save my pics and music? Is it all lost? Help please?
Thanks

My Final Cut Pro X won't load past the start-up screen....Why??

I have been using FCPX for about 3 months now and I have had no problems. Out of NOWHERE today when I tried to open up FCPX it loads everything except for one project and it gets stuck. The start-up screen simply says "reading project 1". I have no idea what to do. I use FCPX everyday for editing videos and now I have nothing. I need someone's help.

Not too many fans of FCPX here. Wrong forum. You'll have better luck here. https://discussions.apple.com/community/professional_applications/final_cut_pro_ x

IMac makes a loud beep on start up, won't load past the blue screen and the black ticking dial appears every few seconds in centre of screen.

Urgent help!
Out of the blue my mac lost the mouse cursor even though it had connection so I rebooted only for the mac to make a loud beep on start up then get stuck at the blue loading screen. It won't load past the blue screen. I've tried to reboot holding down the shift key but no change. I've also shut down, unplugged the main for 15 seconds, re plug and wait 5 seconds before starting up again but no change. Does anyone have any suggestions?
PS: I'm not too sure which systems I am running without being able to check in about this mac. I bought my imac in January or February 2011 if that helps.

The power on self-test resides in the ROM of the computer. This test runs whenever the computer is turned on after being fully shut down (the power-on self-test does not run if the computer is only restarted).
If a fault is detected during the test, you will not hear a normal startup chime. Instead, the system will beep as explained below. If you experience one of these beeps, you may call your Apple Authorized Service Provider for additional troubleshooting assistance.
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable

My macbook air won't get past the white apple screen. I've tried power cycling the batter but won't help

my macbook air won't get past the white apple screen. I've tried power cycling the batter but won't help

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.

IBook G4 suddenly won't boot past the "booting OSX" screen.

My iBook G4 suddenly died and now won't boot past the "Starting OSX" screen. The blue bar goes all the way across but never moves to the next screen. I have my original disks, containing OS 10.4.5. I am trying to boot from the disk, but just keep getting the Installer program. When I try to choose a startup disk, it still won't start. Any help or ideas? This is urgent.
BTW, I am a photographer and was workig in PhotoShop7 -- a program I use all day, every day.

Start from the install disc again and choose Disk Utility from the menu. Highlight the drive on the left and click Repair Disk. If it reports errors and repairs made, repeat the process until no errors are reported.

My Macbook won't get past the start up screen

Hey everyone
I have a Macbook that's about 3 years old. I did an software update yesterday and since doing it the computer won't get past the start up screen. There's just the Apple logo and the rolling ball thing. It's been stuck there for around 30mins and nothing changes. I'm not really sure what has happened but I was wondering if there is any way I can fix it.
Thanks for your time.

Hey Lyssa
I don't have a back up but I'm not to worried about that as it's my traveling computer and I only use it for the web and some word processing.
I don't have the disks with me right now as I'm away from home. I'm not sure what I had updated, I think there was a lot because I hadn't don't it in a long time.
If I can start it in safe mode what should I do?
Thanks.

Upgraded my iphone 4S to 8.0.2 and it won't go past the Hello startup screen or accept my Apple ID Sign in!!! Help!!! What do I do to fix this??

Upgraded my iphone 4S to 8.0.2 and it won't go past the Hello startup screen or accept my Apple ID Sign in!!! It just restarts itself!!!
Help!!! What do I do to fix this??

I doubt that your data have been lost, the hard drive should be fine. Too bad that you're going to sell it, you could have used the hard drive in an enclosure to back up your new computer to. Please remember to make frequent backups/clones, I use SuperDuper! and it works perfectly. I have used it to re-clone a drive from the external when things have gone bad, you can also boot from a SuperDuper! clone.
Anyway, let us know how things go, I'm pretty sure your drive will be fine.

My powerbook won't load past the grey apple logo screen

I had been away on business for a few weeks and yesterday I decided to run the latest updates for my powerbook. In the middle of it the computer froze for what I think is the first time since I bought it 2 years ago. I ended up having to shut the computer down with the power button. When I turned it on it wouldn't and still won't advance past the grey apple logo screen with the progress indicator. It just sits there for hours on end if I let it.
So far I've tried the following, all to no avail.
Booting in safe mode I get the same result.
Zapping the Ram
Resetting the PMU
Reinstalling OS X, during which the computer either randomly shuts down or goes to sleep and then shuts down and requires me to reset the PMU in order to start again.
Running the hardware diagnosis. I did this once and it froze during the logic board test, 1 minute 6 seconds in to it.
Anyone have any ideas that don't involve spending 900 dollars on a logic board? Thanks a lot for any help.

joeuu, thanks for the reply. i checked the airport and the ram and both seem to be seated properly.
i ran the quick hardware diagnosis and it came back showing everything was fine.
when i ran the extended one i got more progress than i did the first time. it got to the RAM diagnosis (about 6:45 seconds in) and then froze - i let it sit like this for an hour and a half to make sure it was actually frozen.
i also tried to run the disc utility from the installation disc and it just sits there with the progress wheel spinning, but nothing else is going on.

My Powerbook doesn't load past the grey apple screen

my powerbook doesnt load past the grey apple strart up screen, after that it sais I need to reboot my computer.
I've tried to boot from my install disk to get disk utillity to run, but the computer will crash again at the gray screen, before it starts running from the cd.
I've also tried to reset PRAM and NVRAM and PMU, it all won't work, and crash on the gray screen.
I dont care about loosing stuff, cause its just been formatted 3 days ago, it started crashing first when my laptop was in the middle of its software (maybe firmware) update.
help! is there any way to get life back to my laptop?
thank you.

sorry, a correction
my computer does start up from the instal disk (finally), and the Disk Utility program sais there are no errors, (in green).

My Mac Mini won't get past the initial startup screen with the Apple logo. What can I do?

After a long distance move, my Mac Mini won't startup past the logo screen. What can I do?

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, boot 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 Fusion Drive or 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 10. 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.

Curve 8900 won't get past the T-Mobile screen on start-up

I am hoping that someone out there can help. My T-Mobile BlackBerry Curve 8900 does not make it past the T-Mobile screen on start-up. The battery was fully charged when this happened. Personally, I think it has to do with iHeart Radio crashing, but I could be wrong. I have tried to plug the USB cord into a rear port on my laptop and launch the Blackberry Desktop Manager to see if I could do anything, but nothing happens. The BB Desktop Manager does not connect to the phone, because it is not getting past the T-Mobile screen on start-up. Not sure what to try.

Hey VTX1300R,
Do you have a recent backup of you device? If so the you may want to try to do a reset to factory on the device. Have a look at this article to see how to do it. http://bit.ly/98bCNO

My G5 shut down + when it restarted it won't go past the grey apple screen

here's a general rundown of how I got to this point...
last yr the hard drive on my '05 G5 went, so i had it replaced (6-7 months ago) and for the last 2-3 months i've had problems with involuntary shut downs (cut to black) it started happening once a day and then there were days where it would happen more often and then less often and eventually got to a point where it was happening every 5-20 minutes, so i brought it in to get looked at and was told that it was the power supply that was malfunctioning. I mentioned that I would likely be buying a new mac in the coming weeks ( i did yesterday) and was told that I should be ok between now and then without having it fixed and then when i did get my new computer they would transfer all of my old data onto the new computer and would be installing the new power supply before selling it to a local school. then, 3 days before I was going to get my new mac, it shut off yet again, but when it rebooted it never went past the grey apple screen. after 4 or 5 minutes the fan comes on and is amazingly loud and this is where it stays until i shut it off. i'm not sure if this is simply the power supply finally going going gone or if this has something to do with the very new hard drive or who knows what else; i just want to get my info from the old computer onto the new and hopefully get the couple hundred dollars that i was told my g5 was worth. is there something i can do to get past the grey screen before i bring it in?
thanks in advance,
Jeremiah

I doubt that your data have been lost, the hard drive should be fine. Too bad that you're going to sell it, you could have used the hard drive in an enclosure to back up your new computer to. Please remember to make frequent backups/clones, I use SuperDuper! and it works perfectly. I have used it to re-clone a drive from the external when things have gone bad, you can also boot from a SuperDuper! clone.
Anyway, let us know how things go, I'm pretty sure your drive will be fine.

My laptop won't load past the main blue screen
