My macbook wont startup

my macbook wont startup, i have tried using the PRAM reset and I hear the second start up chime and then it says start up disk is full and the screen stays blue. What can I do?

Prior to this, were you getting messages indicating that your start up disk was "almost" full... suggesting you you clear up some space? Was your machine running very slow or possibly frequently crashing?

Macbook wont startup or safe boot

I'm getting the blue screen and its staying there after the apple logo goes away. Can't start up or safe boot, but I can boot from a Leopard disc. I dont have disc warrior so thats not really an option. Did disk repair, and permission repair. No good. Any ideas how I can fix this? Its recommended that I wont lose my current data.
I deleted my batteryupdate bundle to update it to 1.2, but the software update on the Leopard wont restart normally after the installation, so I manually it shut it down and started it up. Since then, my macbook wont start up.
Thanks in advance for the help.

If DU pronounced the drive as OK, but you still cannot startup, then you have damaged system files. An Archive and Install should solve the problem:
How to Perform an Archive and Install
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.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
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.

My MacBook Air wont startup after login

my MacBook Air wont startup after login???

Try to boot your computer in Safe Mode: restart and hold the shift key down.
This can take some time, so be patient.
Explanation here: http://support.apple.com/kb/ht1564
If thyis leads to the computer booting, you can restart without holding the shift key down.

Reinstall OS X, either from disc or a recovery partition. You don't mention which version of OS X you're running so I don't know which it will be.

My macbook seems to be going crazy. At certain points (and for hours) I get the oh snap page on chrome, safari doesnt work, macbook wont let me create any files or for example upload music to itunes. I restored my mac so im sure its not a malware problem.

My macbook seems to be going crazy. At certain points (and for hours) I get the oh snap page on chrome, safari doesnt work, macbook wont let me create any files or for example upload music to itunes. I restored my mac so im sure its not a malware problem. The only thing that solves it is switching off and on , but sometimes I have to do that for 6-7 times before its ok or wait for a few hours. Some help please

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
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. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
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.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

My macbook wont boot up :-( HELP!!!!

Hi
HELP!!! My macbook wont boot up.
I was deleting some files off my system last night, Id put them in the trash and deleted them (there was quite alot!!) and the screen gradually went black and told me i needed to restart my computer by holding down the power key.
I tried doingt this but it wouldn't restart.
I left it a while and tried powering up, it seems to turn over once but the chimes dont kick in and nothing happens, the little light (is it the sleep light?) does come on but nothing else.
I really really hope someone can help!

Since you are still using Panther, try booting from your System Install DVD. Try running the +repair disk+ & repair permission options.
See Article http://docs.info.apple.com/article.html?artnum=301287 My computer stops responding during startup
If you have AppleCare, suggest that you contact them.

Disk Utility wont startup

I'm trying to start Disk Utility (under mac os 10.4.8, intel) but it wont startup. It bounces one time in the dock and then dissapers.
I tried a copy of an other computer, but the same problem. I Repaired Permissions in the terminal. I've reset my P ram.
This didn't work at all. Anyone an idea?

Wow, that's not good.
The first four bytes of a "Universal" Mach-O loadable object and/or executable should be (in hexadecimal representation, which is what the "0x" prefix signifies):
<pre>0xCAFEBABE</pre>
but instead, it's saying that the first four bytes are:
<pre>0xCC8B45D0</pre>
In other words, the internal data of the file has been altered or is otherwise incorrect so that it's unusable.
Before doing anything else, I would, if you haven't already done so, startup from your Install DVD/CD and use Disk Utility to make sure your disk directory checks out okay. Use the Verify/Repair Disk buttons to do this. How to repair this problem short of an Archive and Install is a bit tricky.
What exactly did you try copying from another Mac? That could work, but you need to make sure that you only copy it from a Mac of the same architecture: Intel-Mac to an Intel-Mac and PowerPC to a PowerPC Mac. Note that the Disk Utility application itself is most likely fine, there's no need to copy that. What you want to copy is the /System/Library/PrivateFrameworks/DiskImages.framework/. Copy that "DiskImages.framework" folder from another Intel-based Mac and put it into the /System/Library/PrivateFrameworks/ folder on your (damaged) Mac. Replace the existing copy. (You'll need to click the "Authenticate" button to enter your password in order to accomplish this). Then try launching Disk Utility to see if it will launch successfully.
Hope this helps....

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.

That indicates a hardware failure. Read here:

If nothing works, you most likely have a hardware failure. Make an appointment at an Apple store to confirm.

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

My macbook wont boot up, black screen and the cd drive keeps making a constant sound. What to do?

My macbook wont boot up. When I turn it on, the screen turns black right away and the cd/dvd drive keeps making a constant "ejecting" sound.
The strange thing though is that once in a while starts up propperly, but suddely goes black again (after a min. or two), and the ejecting sound comes back. What to do, and yh, I've never done a back up so would it be possible to take out the HD and regain whats in there?
Any help would be appriciated!

Hello. Try resetting the PRAM and SMC first.

My macbook wont sync the music i downloaded onto a flash drive and onto the mac book what do i do?

My macbook wont sync the music i downloaded onto a flash drive and onto the mac book what do i do?

If you subscribed to iTunes match the songs are kept in icloud. If you didn't but you did save the actual iTunes library folder which should include the music, video, etc. you should be able to just drag this file back to your machine in the same place and when you open iTunes it will give you a chance to identify the iTunes library folder.
You can test this to find out if you saved the media files or not and don't need to attach your nano to do it.
You are correct that once you connect the nano it will clear the existing files from it and sync it with the new iTunes library.
If you don't have the media files i'm not sure if/how to get them back on a windows ipod. I have everything backed up regularly because of the horror stories I have seen & heard.
