OS X will not start in Safe Boot but it does start normally

I have not been able to install updates for TurboTax or Quicken; the updater hangs. Intuit customer support suggested trying to install them while the computer is in Safe Mode. Big surprise: it brings up the Apple screen and the spinner, but after a few minutes the computer shuts down.
It starts normally otherwise; just not in Safe Boot.

but after a few minutes the computer shuts down.If your computer shuts down when attempting a Safe Boot, this means the filesystem check is failing.
You need to boot from your Install CD/DVD by holding the "C" key down while you restart. When the Installer appears you need to select Disk Utility from the menus (which menu it is on varies, do a search).
You can then choose the "First Aid" tab, and click the Repair Disk button. If you are lucky, it will report that it fixed some errors, in which case run it again until it says there are no errors. But given that Safe Boot does this automatically, you are more likely to get an error that it is unable to fix—at least you will see what the error is, and can post it here.
You may need to invest in a third party Disk Repair program like DiskWarrior to fix this. But you must fix it before attempting to install anything else.

G4 iMac will not start normally

My wife's G4 iMac will not start normally. I have used the procedures from http://docs.info.apple.com/article.html?artnum=107393 and the "Disk Utility" on http://docs.info.apple.com/article.html?artnum=106214 to no avail.
When trying to start, a message comes up saying that the computer must be rebooted. Trying to boot in "Safe Mode" fails after an hour and shuts down the computer, and the "Disk Utility" runs for an hour or two and then gives a message that it was unable to repair the "minor error" on the hard-drive.
After force starting the iMac by holding the power button until the command line appears, I tried running fsck, but the commands are unrecognized. However, if I type in "mac-boot" at the command prompt, the iMac will start. I have copied all of my wife's photos, movies and music, and Word and Excel documents, etc. to my XP PC's hard-drive using USB flash drives.
My question is two-fold:
#1. I have heard that "Disc Warrior" is excellent at resolving hard-drive errors. Can anyone comment on "Disc Warrior" and is there anything else out there that someone can recommend?
#2. I bought RAM to bring the total up to one gig, so I was thinking of upgrading the hard-drive and installing Tiger on the new and larger drive while in the "Ball" changing the RAM. What is the maximum capacity hard-drive I can put into the G4 800mhz iMac without any problems and is there any particular model hard-drive that seems to work best?

I tried reading the link that you posted http://www.thexlab.com/faqs/kernelpanics.html but I don't have a disk with the "Apple Hardware Test".
Since I made the post that you replied to, things have gotten worse. I can no longer get onto the internal hard-drive. I have tried many different methods including the methods written about in the linked article you supplied. I can get onto the Installation CD and I can run "Disk Utility" from the CD. I have repaired the file permissions, but when I run "Repair Disk", it runs for about two hours and then suspends operations with a dialog box stating, "First Aid failed. Disk Utility stopped repairing Volume because the following error was encountered: The underlying task reported failure on exit." and then in the progress box after the list of addresses, there is a message:
(in red) Incorrect number of thread records
Invalid leaf record count
Invalid Map Node
Invalid directory Item Count
Invalid directory Item Count
Invalid volume directory Count
Invalid volume file Count
Volume Bit Map needs minor repair
Invalid volume free block count
Volume header needs minor repair
(in green) repairing volume
(in red) The volume could not be repaired
Error: The underlying task reported failure on exit
(in black) 1 HFS volume checked.
(in red) 1 volume could not be repaired because of an error
(in black) repair attempted on 1 volume
(in red) 1 volume could not be repaired.
I recently bought the 1/2gb replaceable RAM and the 1/2gb "Hidden" or "Factory Installed" RAM. I was planning on installing them soon. Since the "Disk Utility" is telling me that there are faults on the internal hard-drive and I have to go into the "Ball" to replace the "Hidden" or "Factory Installed" RAM, I figured that I might as well replace the hard-drive and redo the system.
Unless someone comes up with something I can do which will not cost me much money, I figure that I might as well install the RAM and a 120gb Western Digital Hard-drive that is about a year old, but was only used for a few days in an XP PC. Will the 120gb drive be recognized? I was thinking of partitioning it as 80gb and 40gb partitions. Does that sound good? I would install the OS on both partitions so that I could always boot if there was a failure.

OSX 10.5. Will not start normally. Startup sound, then shutsdown.

OS X 10.5. Will not start normally. Startup sound, then shutsdown. Will start with startup disc inserted holding "C". 297.8gb capacity. 297.3gb used. Say's must format HD to install. How can I free up space to save my stuff? Can't access anything on HD. Disk Utility First Aid no help. What can I do?

Boot from the startup disk and run disk utility, repair permissions and repair disk as well. Reboot and see if this helps.
Your startup disk is completely full and could be why it will not boot. If you have access to another Mac and a firewire cable you can boot your broken Mac into Target Firewire mode by holding down T at the chime. This will then mean your broken Mac appears as an external drive on the other Mac allowing you to delete some files and see if it will boot once you have freed up some space.

Mac mini shut down on its own, will not restart, grey screen, spinning wheel. Unplugged everything, will still not restart. Did safe boot, will not restart after safe boot, only grey screen with spinning wheel.

Mac mini shut down on its own. Could not restart, chime, grey screen and spinning wheel. Unplugged everything but monitor, still only chime, grey screen and spinning wheel. Started in safe boot, shut Down, will not restart.
This happened a couple of months ago, unplugged everything and it restarted, now that won't work.

Hi BDAqua,
I just did the repair as you suggested. T ran the disc repair, and twice it cam back, the volume macintosh seems ti be okay, I also ran the verify and permissions repair, both came back okay.
I was actually hoping that they would find something, so they could repair. I shut the computer down, and restated with out holding a key, and I started up great. I'm baffled. I have moved 20 GB to an external hard drive, as I only had 10% open space.
I have Tech Tool 6, would you recommend to run a repair check on that, or just leave well enough alone.
I agree with you on the new Mac's, I have problems with no disc for back up, until they realize their mistake I will stay with Snow a Leopard. This is the first problem I have experienced, so I can't complain. Their last programs are not as perfected as under Steve, prior to his handling over the reins, hope this is not going to be the future we can expect from Apple.
I will wait to here back as to your suggestion regarding the Tech Tool check
Thanks for all your help.
Gratefully,
Cheri

Firefox will not start normally, but will in safemode. How can I fix this?

Everytime I go to start firefox, it never starts, and tells me it's crashed. It gives me the option to reset firefox or restart it in safe mode. Resetting firefox does nothing, but presents me with the crash again, instantly, the split second firefox tries to run.
I've reinstalled firefox, restarted my computer etc etc. I don't and never have used any addons / extensions. I've never used anything but the default theme. I do have ~12 things on my favorites list, but that's the extent of it.
This is frustrating, as I don't like to use IE. Any help is appreciated. Thanks.
Regards,
David

Itunes will not recognize my ipod touch but windows does

I use windows 7 and everything was fine until I updated to the most recent version of Itunes 10. something. Now when I plug in my Ipod windows recognizes it but I get this message from Itunes: iTunes could not connect to this iPod because an unknown error occurred (0xE800000A)
Any ideas?

I have no navigation bar and firefox will not open in safe mode to reset to default config. Reinstalling doesn't work. Any help please.

I have no navigation bar ever since I closed it to gain more space on the screen. It won't re-open. Firefox will not open in safe mode, but opens immediately in normal mode with the new improper config, so I cannot reset to default config. I erased Firefox and re-installed and it still opens with the same faulty config. Why does Firefox not give me the safe mode dialog box, why can I not re-open the nav bar, and how can I do these two things, please? Firefox is currently unusable for me without a nav bar and without access to the default settings in safe mode. I cannot research the extensions I'm running since I have no nav bar to go to Tools, Add-ons, Extensions.

Will not start even in safe boot after installing latest camera update

MacBook Pro will not start even in safe boot after installing latest camera update.
I started my machine and did a software update. Only the camera update needed. So installed and when required I pressed restart. It restarted and did install. Then restarted again. I expected to get to the login screen and it turned itself off. Tried three more times. Each time shutting off. I unplugged everything, and pressed start waiting for log in window. No it shutdown before the log in window. I then tried safe mode and that did not work either on three more occasions.

I have managed to resolve some issues. I can now restart the machine via a CD boot. If I do cmd C into something like tech tool pro, then restart from that disks menu it restarts every time.
If I try a safe start it shuts down. If I try a normal start it shuts down. I have managed to repair permissions and that cleared up some start up permissions but with no improvement to the boot problem. The only way to load is via the cmd-C boot option. Any other ideas?

MacBook will not start. I have restarted with original CD. I have used Utilities and "no problem" with hard drive. I have reset PRAM. I have tried safe boot. Nothing is work. Gray screen with Apple logo and rotating wheel. Thanks for any suggestions!

Snow Leopard is a Mac OS X version. You say that it's the version you have in your Mac (10.6.8). Do a back up of your files, format the hard drive (using Disk Utility) and reinstall again

HT1455 What if my computer will not start up in safe mode? What next?

What is the remedy for a MacBook that will not start up in safe mode? The gray apple icon and progress wheel appear, I let go the shift key and the whole thing shuts off again. Please help. Thank you.

My understanding is that the Apple logo is produced by the disk and the spinning wheel shows that the software boot process has started.
1 - Shut down your Mac
2 - Press the power button to start and
3 - Immediately press and hold the Command (Apple) key and the S key
4 - At the prompt type the following and then hit return:
/sbin/fsck -fy
fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issues were found:
** The volume (name_of_volume) appears to be OK
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command you typed in step 4 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do). When fsck reports that your volume is OK, type the following at the prompt and hit return:
reboot
Your computer should start up normally and allow you to log in.
Good luck.

MacBook Pro has a grey screen with circle and slash and will not start up or start into safe mode.

MacBook Pro has started to get a grey screen with circle and slash and will not start up or start into safe mode. This happened once previously, however, it allowed a safe mode reboot and then worked for a week or so. While utilzing the machine, it started with the spinning beach ball for about 5 minutes, went into a shut down mode and then rebooted and came back up with the grey screen with a circle and slash after a few minutes. For the past three days it has been stuck and will not allow it to boot into safe mode. Any idea or suggestions?

Try starting the MBP with the OPTION key down. If you see two HDD icons, select the recovery Icon. From the 4 option menu, select Disk Utility. Select Disk Utility>First Aid and run Verify and Repair.
If you cannot get into the recovery partition, make an appointment at an Apple store genius bar.
Ciao.

Firefox 3.6.8 will not start. I have to go to safe start, click reset to default, ok, then the shutdown box appears, I click cancel and it will open. I have rest profile, uninstalled and reinstalled, clicked alll he boxes on safe start, tried an older version need help. in English
== This happened ==
Every time Firefox opened
== either after I last updated to 3.6.6 or .7 or reset my inernet exploerer values to default

I had same problem where Firefox 3.6.8 would not start or open. Spent many hours trying different things to fix it. Uninstall of previous version and reinstall did not make any difference. Finally, after uninstalling Firefox, I searched for Firefox folders and files on my computer, deleted and removed all Firefox folders and files - deleted anything and everything related to Firefox so that it will be as if I was going to download Firefox for the first time ever. Then, using another browser, I downloaded Firefox 3.6.8 and installed it. It could be that some Add-Ons or something else from the older version of Firefox or profile was interfering with the new one. It was easier to delete remove everything and install all over again clean than to figure out which part was causing the problem.
Keep in mind, when you delete all Firefox folders and files from your computer, you are deleting all your bookmarks and all your Add-ons. If you want to keep those bookmarks, you might want to save the URLs someplace safe to bookmark them again before deleting them. You need to re-install the Add-ons also. Upon installation, it asks if you want to import bookmarks and settings from another browser or settings you might have. I imported them from my other browser. Now, Firefox works. I also installed up-to-date Add-ons.
I hope this helps. Always keep more than one browser functioning on your computer, just in case one fails.

Firefox will not start, even in Safe Mode. Evidence suggests that this is due to an incompatibility with the latest update of Java.

Firefox will not start in WinXP. (I am sending this from an alternate browser.)
I believe that this is due to some incompatibility with the latest update of Java. I believe that one of the tabs from my previous session included a Java application, and this is causing the difficulty. In recent days, since the last update of Java, I have had difficulty in loading linked pages with Java applications into Firefox, and have needed to switch to a different browser to do this.
Now I cannot even start the browser, presumably due to the presence of a Java application on one of the restored tabs.
When I now try to start Firefox, my ZoneAlarm security s/w presents the message "Java(TM) Quick Starter binary is trying to access the Internet." I click "Allow", but Firefox will not start. If I click "Deny", the same result. The same thing happens when I try to start Firefox in Safe Mode, I cannot even start Firefox in Safe mode.
== This happened ==
Every time Firefox opened
== after recent update of Java

You can try to disable the Java Quick starter and the Java Console extension in the Control Panel > Java.
Control Panel > Java > Advanced tab > Miscellaneous >Java Quick Starter (disable)
You can also disable the Java plugin in Firefox: Tools > Add-ons > Plugins
