Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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 Utilities menu. 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 click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro 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. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

My computer won't turn on, it just stays on the blue screen, whats wrong?

This has happened before, but the problem was supposed to go away. A window pops up randomly and says "start-up disk is full" and i just click "OK" and move on. But then today i turned off my computer and about 30mins. later I turned it back on and it got stuck on the blue screen. WHAT DO I DO?????

Reboot holding the Shift Key down and target some large files like Movies to copy to a external storage drive, then delete them from the boot drive and reboot a couple of times so OS X realizes there is new space available and boots normally again.

IMac won't start up, can't get past the white screen

I have an older iMac, I believe it's the g5, the white one, got it about 6 years ago or so. It was acting up recently, crashing programs, taking a long time to respond etc. I figured I just had too much stuff on my hard drive so I went out and bought an external hard drive. After I copied over a bunch of files (not everything, my music and my photos aren't backed up!) I then deleted the files I transferred from the iMac to make room. It took a very long time for the trash to empty, and then I tried to restart. It shut down but never rebooted. When I press the power button it will only get to the white screen with the gray apple and gray progress wheel. It stays like that for a minute or two with the wheel turning but barely any progress on the progress bar and then it turns off. I tried unplugging everything including the power cord but nothing works. Any ideas? Thanks.

will it start in Single User Mode ? (Hold Command + S after hearing the chime)
If so, follow the fsck section at http://support.apple.com/kb/ts1417
and when/if you (finally) get a 'volume appears to be OK' message
don't restart afterwards.
then, still in single user, type the command df/ followed by enter
making sure that the result shows Capacity at some reasonable level, like 90% or less.
df means 'display free disk space', you're checking that the drive isn't so horribly full that attemoting to start might further risk your data
if Capacity is ok- reboot as per the article; if not, post back.
If you can boot in Single User & have done the above, but still can't start normally - try
Safe Mode to see if you can copy your files off.
If Single works, but nothing else, it's probably possible to copy your files in that mode, using typed commands.
if you can't start at all -
Checking your exact model at http://www.ifixit.com/ will show how hard it is to remove the HD yourself... some are pretty easy with the right-sized screwdrivers, and the drive can then be taken to anywhere with a computer & the right cable/adaptor to copy your files.
or
Target Disk Mode : http://support.apple.com/kb/ht1661
if it works for you, would let someone with a computer & firewire port access any of your files that are intact. Apple may, as mentioned, say it's too old for them to look at.
finding the dvd's/getting replacements would be best.

Help my mac won't start up all I have is a blue screen!

Last night my mac failed a security update, which I thought was strange but didn't take too much notice. Now it won't start up all I have is a light blue screen and a grey spinning circle
Help!

Nunu,
Ended up re-installing OS X all seems ok now although itunes won't work. Have downloaded system updates but now quicktime isn't current enought!
ARRRRRHHHH!
Well since you have a 450 I would suggest you keep a clone of your updated hard drive. That way if something happens you can just clone back from your update and not have to go through all the updating.
I've done that with my iBook and it's now crashed 3 times so it's sitting here waiting for me to put in a new hard drive. I have two clones of it so no problem.

Macbook won't start up at all, stuck on a black screen.

I went on my Macbook this morning, for about 20 minutes and then suddenly it turned off (whilst plugged in). I tried turning it back on but it wouldn't. It has charge (I checked the battery indicators) and help would be much appreciated as I have a lot of important information on there.

and how can I fix it without losing everything again?

Mountain Lion update, and now computer won't start up?

Writing this for a friend, as his computer is inop at the moment. Hence this message.
He has a new 27" iMac. He upgraded to Mountain Lion a few weeks ago, and then had intermittent problems with apps unexpectantly shutting down.
Now he did a ML update this morning, and his computer won't start up. It gets to the point of the Apple logo coming up, a progress bar, and then the spinning wheel, but then shuts itself down right afterwards.
A safe boot yields the exact same result.
Any thoughts out there on what he could try to get it up and running again?
Thanks much for any and all help.

Thank you for the fast response.
He was able to get into Disk Utility with the Command and R keys, but when he tried verifying the disk, in red it said 'Invalid Node Structure, volume could not be verified completely'.
He went ahead and verified it anyway, then proceeded to repair it. Howver, it stopped repairing, said it cannot repair, and that he should back up files and reformat the disk.
How can he back up his files? He cannot see a way to do it. Is there anything else he can do besides having to reformat the disk?
This is his first Mac (after much prompting from me to go Mac), and he's afraid he's now lost everything on there.

Computer won't start up, stuck on gray logo screen.

Hey I have been having this problem for about 2 days now. When I try to turn on my computer, it won't fully start up, it gets stuck on the grey screen with the apple logo and stays like that forever. I tried to fix the problem using single user mode, typing "/sbin/fsck -fy" as well as trying to go on recovery mode and pressing "repair" on disk utility, MacHD ect. Now I have a backup from a month ago but is there any way to fix the problem? The error is: incorrect number of thread records. Oh and I have bootcamp, windows on Mac that run fine, I'm guessing that might have messed with my computer a bit though. Please let me know how to fix this soon. Thanks!

If you want to preserve the data on the boot drive, 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, you can skip this step.
There are several ways to back up a Mac that is unable to fully boot. You need an external hard drive to hold the backup data.
1. Boot into Recovery (command-R at startup) or from a local Time Machine backup volume (option key at startup.) 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
2. 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
3. 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.

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

Ibook G4 freezes either when its on the grey loading screen or the blue screen. Sometimes I get it to my desktop but it always freezes in like a minute. Someone help I really need this computer!

It either gets stuck on the grey loading screen or the blue screen. Rarely I am able to boot past everything and get to my desktop but after about 30 seconds it freezes again.

I need more options.. Please this is the only computer I have right now! (PS: I know warranty has expired a long long time ago)

Can't Start Up: staying in the blue screen for 8 hours...

HELP!!!!
My powerbook G4 can't start up
All goes well during StartUp untill it gets to a Blue Screen
then it stays there
its been 8 hours so far...
( i can see the mouse pointer )
This is my 3rd try -- but every time it just stuck in the blue screen stage
Please help.

First, I'd review the troubleshooting procedures on this page:
http://www.apple.com/support/powerbook/
Other things to try: remove the main battery and let the PB sit with the A/C adaptor connected for several hours. This will make sure the backup battery has some charge assuming it's not completely dead.
Then try starting the computer with the SHIFT key depressed ("Safe mode"). This does some directory repair. If you get a desktop via a safe boot, do not try to use the computer just yet. Do a normal restart, then see if it is usable.
If you have your system disks or the disks you used to install Tiger, dee if the computer will boot from them by holding the "C" key during boot.
How full is you hard drive? You need a minimum of 15 percent free space for the OS to work with any efficiency.
Because there are several variants of the 17" G4 PowerBook, it would be helpful to people here if you would add the processor speed to your equipment line. Showing how much RAM you have is also useful. That way you can get help faster because people don't have to ask first.

HT1492 Start-up disk is full and can't go past the blue screen; can't delete read-only files on single-user mode. Please help.

I have had my Mac mini for about 6 years and I guess it had enough of me (haha), so the start-up disk got full and it shut down before I could empty files on my drive. Unfortunately, all these years I hadn't backed up anything and now I can't access anything since it won't boot past the apple logo (and the blue screen for that matter). I have tried rebooting (holding shift as the mac mini loads), but that didn't help since the start-up disk will still be full and stuck on the blue screen. I am now trying the single-user mode (holding command key+s), and I tried to delete files in the trash bin but all of the files are read-only and access is denied! so I basically can't delete anything on the mac mini (it says "Root device is mounted read-only"). So the key here is to change the permissions but I don't know how to exactly do that. Can someone help me figure this out? (and type the command in the unix language please!!) [ Note: We have two users on this mac mini if that helps.]

Run the following command:
mount -uw /
This isn't a permissions issue.
