Cant log in even in safe Boot

My powerbook, all of a sudden, after I turned it on one morning, never arrived to the desktop. It passes the grey apple and the spinning gear sign, on to the aqua fill of Mac OS X, and then what usually appears, the desktop picture, doesn;t. It stays at a blue screen with only the mouse cursor visible.
I tried rebooting in safe mode to follow some suggestions from another article
http://docs.info.apple.com/article.html?artnum=106464
but after I type in my password to log in in safe boot, the screen turns blue and then it returns to the safe boot log in screen asking for my password again.
HELP
Mario

im sorry, but I am one of the most anxious persons you'll ever meet.
I backed up all my files on an ipod and connected my computer as an external harddrive to my friends powerbook. From his computer I opened up disk utility and I restored my harddrive, which basically erased everything. And now when I turn it on there is a question mark and an OS9 folder and icon smile. I was expecting that however.
I assume that now I have to insert my startup discs and install everything afresh (which is probably a good idea since this is not the first incident).
Is there anyway possible to install startup without the discs-- I say it because I have my start up discs in an apartment in another city that I am not in at the moment. I am going to have to wait aren't I?
But will it be possible to install start up with what I've done?
I promise Im not doing anything else to it\

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?

MBP running Mac OSX Leopard 10.5.8 cannot get past login screen even in safe boot

Help! I have a Macbook Pro purchased in 2009, running Mac OSX Leopard 10.5.8 which froze while running Adobe Illustrator. On reboot, it won't allow me to go past the login screen. I tried starting up from the disc, running disk verification and repair and repairing disk permissions, and trying to start up in safe boot, all to no avail. When the login screen comes up it gives the name of my hard drive with a (2) after it, which seems strange. Any suggestions short of reinstalling the system software? I don't want to lose my applications/data!

Is there any simple software that can boost overall performance or will I have to reformat my MBP? I have a 200gb HD with 50 gb free and 4 gb of ram.
Welcome to Apple's discussion groups.
Launch the Activity Monitor utility. Pull down the list near the top and set it to "All Processes". Click on the "CPU" column heading to put the highest CPU consumers at the top. Also click on the "CPU" tab in the lower part of the window to check the value for "% Idle". If that value is much above zero, check the other categories for signs of resource problems. If nothing there points to a possible problem, launch the Console utility and look for messages that might suggest a problem. If you see messages that you have trouble interpreting, post them here and someone should be able to help.

MacBook Pro won't sleep, even in safe boot

Hey gang,
I can't figure out what to do with this problem. I recently did an archive & install of 10.5 on my 2.33 GHz MacBook Pro Core 2 Duo, and then used software update to get to 10.5.2.
Ever since doing that, my MacBook Pro will not sleep on its own anymore. It will sleep the display, but it won't sleep the system. (I can close the lid and it will sleep. I can also choose "Sleep" from the Apple Menu, and it will sleep. It just won't sleep on its own.)
At first I thought it might be Time Machine that was preventing it from sleeping, but I turned off Time Machine and the problem persisted. I tried creating a new user, and the problem persisted. In fact, I EVEN BOOTED IN SAFE MODE AND THE PROBLEM PERSISTED!
I went through every single step outlined on this page (yes, every single step), and the problem still persisted: http://www.macfixit.com/article.php?story=20070129234938244
Does anybody have any ideas what I can do at this point? I'm pulling out my hair over here....
Thanks!
Scott

I see you've done your homework. I have this no auto-sleep problem on my Mac pro and none of those things worked for me either but I thought you should give them a shot.
I made a little sleep program of my own. You are welcome to try it. It's a very simple shell script that checks system idle time and if it's bigger than the sleep timer you set in system preferences it puts your computer to sleep. It will work so long as you can manually put your computer to sleep from the apple menu.
You'll also need to create a launch daemon to periodically run the script.
here are the steps to do it.
1. copy and paste the following into TextEdit.
#!/bin/bash
idl=$"`ioreg -c IOHIDSystem | awk '/HIDIdleTime/ {print int($NF/1000000000); exit}'`"
sleeptimer=$"`defaults read /Library/Preferences/SystemConfiguration/com.apple.PowerManagement "Custom Profile" | grep "System Sleep Timer" | awk '{print $5}' | sed -e 's/;//g'`"
st=`expr $sleeptimer \* 60 `
if \[ $idl -gt $st \]; then
shutdown -s now
fi
2. Format it as *plain text* (shiftcommandT in TextEdit) and save it as sleep.sh (don't use the .txt extension) at the top level of your hard drive.
3. make it unix executable by entering the following command in terminal.
*chmod 755 /sleep.sh*
4. Download and install [Lingon|http://lingon.sourceforge.net>.
5. Open Lingon and create a new *Users Daemon*
Call it,say, com.sleep.launchd (the name is not important)
On line 2. enter /sleep.sh
and in section 3 set it to run every 30 seconds.
Click save (you'll have to enter your admin password).
6. Restart.
That's it. Once this is done you can forget about it. The sleep settings are still controlled from system preferences. The sleep agent will work with every user and even over the login window.
To uninstall it, open Lingon, select the launch daemon you made and uncheck the box "Enabled" in the upper right corner. save and restart.

Got capital A for all letters in a box. Now it is taking over 15mins to start up even in safe boot.

Not starting now.

That's probably some sort of font problem, either a font that's required by OSX has been removed, or is damaged.
If you haven't made any progress, post back and I'll see if I can find a font guru for you.

Can't get past Log-In window--Safe Boot

I'll try and keep this easy/short: My iMac g-5(first Gen i-sight), when upon startup, the wheel would just spin and then the fans would blow turbo while stuck on the spinning wheel. Was running on Tiger but was able to salvage the h/d and all on it, no damage to it. So we erased all on my iMac and tried booting from disc. No good. Tried starting from another laptop; No good. Then cloned from working Leopard laptop, did basic install and got to the Log-in widow--in Safe Boot mode and cannot get past the Log-in window. I get a dialogue box w/an applications icon that says, " You are unable to log in to the user account "..." at this time. Logging in to the account failed because an error occurred." I hit okay and the dialogue box shakes a frustrating no at me.
What do I do now?
Any ideas? Thanx to all.

Try an Archive and Install now, it will put a fresh copy of the OS but keep, your data and preferences. Cloning from a different system is not a very good idea, you run into the problems you have, and probably other ones as well.
If the A&I doesn't work, you may have to wipe your drive and perform a clean install of Leopard.

Does Safe Boot clean font caches?

I found this in the OS10.4.11 Help file under Safe Boot:
"Mac OS X 10.4 Tiger only: It moves to the Trash all font caches normally stored in /Library/Caches/com.apple.ATS/(uid)/ , where (uid) is a user ID number such as 501."
Someone in another forum tells me that it isn't true. Is it?

So, if there were more than one user account, safe boot will only clear the font cache for the user who logs in while in safe boot. And if you then logged in as another user, it would clean out that cache (not that this is what people would normally do, but I'm just trying to understand all of this).
But, the system font cache is not affected, right? So if I suspect a font cache is causing problems, leaving the system cache unchanged might not relieve the problem.
You've got it!
Rather than trying to track all of the various font cache (and other cache files) yourself, there are free utilities you can download that do all of the work for you. Font Finagler clears just font cache files. If you want to clear other cache files at the same time, OnyX can do that.

Upgraded memory from 4Gb to 8Gb on June 28th.
Tried to write on my external HD (previously written on a windows based PC) with no success.
Upon reccomendation from a Mac assistant, copied all my external HD contents into my Mac Hard drive.
Then formatted my external HD and copied back all my information to it.
deleted all the information from my MacBook Pro HD.
Attempted to repeat the same operation with another external HD, but got a message saying there was not enough epace on the computer HD (even though I have a 750Gb Hard Drive.
Looked in the trash bin and there it was, all the information previously deleted..
Could not empty the trash bin, although I got a message asking me to safely delete all the information from the trash bin,
Could not get enough space released, after several attpempts the trash bin was finally emptied.
All happy getting acquainted with my new MacBook Pro. Two days later, got a gray screen and not able to start the computer.
Looking in to Mac support I found article http://support.apple.com/kb/TS2570 and followed instructions to perform a safe boot:
"Perform a Safe Boot
Simply performing the Safe Boot may resolve this issue.
Shut down your Mac. If necessary, hold your Mac's power button for several seconds to force it to power down.
Start your Mac, then immediately hold the Shift key. This performs a Safe Boot. Advanced tip: If you want to
see the status of a Safe Boot as it progresses, you can hold Shift-Command-V during start up (instead of just Shift).
Note: A Safe Boot takes longer than a typical start up because it includes a disk check and other operations.
The following is the script that appears on the screen upon safe boot. and halt after the last line.

Satellite L300-1AP will not boot even in safe mode

After trying to boot in safe mode I get (after 10 minutes or so) the following.....
Windows failed to start. A recent hardware or software change might be the
cause. To fix the problem:
1. Insert your Window installation disk and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disk, contact your system administrator or computer
manufacturer for assistance.
File: \Windows\system32\config\system
Status: 0xc00000e9
Info: Windows failed to load because the system registry file is
missing, or corrupt.
As the the OS was pre installed, no Windows disk is available. Have tried Windows repair, but get a similar message. Have tried F8 upon boot and have tried to restore to most recent working state but get the same as above. Is there any other way of repairing this or is this a hard disk issue? Help!

Thanks for your reply Horwath, unfortunately after about 15 minutes I get this instead:

Macbook fails to boot and safe boot won't log in

Hi All,
This is my first post here after owning a mac for about 2 weeks and then having a serious problem that needed a good dose of Unix know how to fix!
Symptoms are:
1. If you try an boot the Macbook you get a blue screen with a working mouse pointer but nothing else and none of the shortcut keys work
2. If you try and boot in to Safe Boot it won't accept a user name and password (not even root) and gets into an infinite loop.
Cause:
Something called ypbind is trying to contact a Domain that doesn't exist so it gets into a loop and fails. This problem seems to be fairly easy to achieve by playing with the Directory Utility (I was trying to connect to a Windows work group).
Solution:
Boot the macbook into Single User mode (by holding Command-S during start-up). You may need to do a hard reboot by holding down the power button to get it to restart.
At the command prompt locate /etc/defaultdomain and clear its contents using Vi or Pico. Some people have suggested that you can delete the file but clearing it works as well. Then reboot (type exit). The machine should reboot fine. Other things I did to be on the safe side were to check the hard disk and check the permissions using the diagnostic tools on the OSX install CD (it's bootable).
This took me ages to sort out so I hope this helps someone else in the same position.
Regards,
Mark

I have just managed to get duped into getting re-infected with that same PC Optimizer Pro virus.
Ordinarily, System Restore does not remove all the damage from a virus.
Now that you're able to back up your important files, it seems best to to restore the hard disk to its original out-of-the-box contents and reload the applications.
   Settings > Change PC settings > Update and recovery tab > Recovery tab > Remove everything and reinstall Windows
If that doesn't work, you can obtain recovery media from Toshiba. Scroll down to Get Recovery Media here. For instructions, see the section Restoring from recovery media, which begins on p. 57 of the User's Guide.

Can't Boot after crash, even in safe mode!

My Mac froze while idle with Lightroom open. It may have hung while remotely copying something off an external hard drive.
But now it won't boot even in safe mode with all USB peripherals detached (including the hard drive that I might have been copying from).
In and out of safe mode, I get the same behavior. After the sound and the grey apple appear, there is also a progress bar, which I don't recal seeing before. It takes about 30 seconds and the progress bar advances about 10-15% of the way and then just power's off.
Is it the main disk drive?
This is an iMac that is several years old with all of software update applied. I don't believe that any software updates were applied recently. I assume that the 10.6.3 update was installed.
Is it the main disk drive?

I had the same problem on my MacBOOk Pro and iMac on 14th April - i had to reformat the harddisk and could restore from my Timemachine backup to the last 10.6.2 state only. Both happended after updating to 10.6.3. But my laptop was sluggish. Based on feedback, I reformatted my hard disk and carried out a fressh installation from my snow leopard disk (10.6) and updated it to 10.6.3 using the 10.6.3v1.1 combo update about a week back. The machine was definitely faster - but yesterday, the same problem reoccurred - the machine froze and would not boot even in safe mode. Repairing the hard disk using the boot CD did not work either. Just now I reinstalled Snow leopard from the OSx CD - it has replaced the OS and left all apps and data intact. I have upgraded it to 10.6.2 only.
My desktop iMac has been running without problems on 10.6.2 for the last 3 weeks. In my opinion, the problems of freezing (reported by others) and this one here are all related to boot sector corruption due to some problem in 10.6.3. There have been some reports suggesting that after 10.6.3, the CPUs are heating up more. The CPU temp was close to 70 deg C when on 10.6.3 - it maybe that some change after the update makes the processor overrun leading to this boot sector corruption - it generally happens slowly over days or weeks slowly accumulating to a break down point.
My suggestion from my experience over the last one month, is stick to 10.6.2 - don't update to 10.6.3. I am hoping Apple will fix the problems in 10.6.3 update soon.

OS 10.2 Won't boot even in safe mode

I was having problems with the Finder on my work i-book so reinstalled the OS. The first disc was fine, though the second wouldn't be recognised. Since it said that this disc could be installed later, I quite the installation and rebooted.
I went to the log-in screen and discovered that my password would not be recognised.
So I used the install disc again to reset the passwords, though didn't actually do the installation again (and since it wouldn't let me shut down properly within the Installer I had to reset the computer by just holding down the power button).
Upon restarting the password now worked, though when I logged in I got taken into Darwin. Since I didn't really know what to do I restarted again by holding down the power button.
And now nothing happens. I get to the grey screen where the apple logo is visible and the little spinny icon goes round but nothing happens after that; I've tried with and without the install discs installed (holding down c obviously) and have also tried to do a safe boot following apple's instructions with no joy.
Anyone got any further suggestions?
Many thanks,
t

Sometimes when the 'C' key doesn't work, you can try the Startup Manager described below:

Hope this helps.

HT201250 my mac froze on a grey screen after i tried to login so i tried a safe boot, but now i am stuck in the startup utilities program and i cant get out of it

My mac froze and wouldnt startup because it was forced to sleep while a complex program was running, and simply ended up on a blank grey screen, and this happened upon every startup. so then i tried to use a safe boot but this ended me up on the startup utilities thing. i have realised that none of the options: restore from time machine backup, reinstall osx mountain lion, and repair disk are available to help me startup, and i cant select a startup disk either as it says none are available. so i am stuck on this program and it reapears every time i restart or shutdown and reboot, so i cant do anything. Please is there any way i could either quit startup utilities or get back to my computer desktop as i have lots of non-backed up image and video files that i cant afford to lose. please help!

Maybe this will help.

2007 Mac Pro will not boot, even in safe mode

Hello,
I have a Mac Pro purchased in 2007 that had been working well up until a few months ago. I had trouble with Microsoft Word 2008 repeatedly crashing; I repaired the hard disk and moved up to Word 2011, and the problem seemed to resolve.
Yesterday, the machine crashed, and I am not able to start it up, even in safe mode. I have tried resetting the SMC and NVRAM/PRAM, removed and cleaned the graphics card (NVIDIA 7300 GT), and removed the 3rd party RAM I installed at least 2 years ago.
When booting to the internal hard drive, the Apple logo will show, then a blue screen followed by a gray screen with a frozen cursor. When I boot to an external hard drive or the OSX Leopard install DVD, the screen flickers like below:
When I tried to boot in safe mode while holding shift + command + V, the safe boot froze after reading:
panic (cpu 2 caller 0x2abf6a): kernal trap at 0x0029a4bc, type 14= page fault, registries:
[4 lines of 2-3 letter acronyms and numbers]
Error code: 0x00000000
I am thinking of buying a new graphics card (ATI Radeon 5700), but I want to be sure (as much as possible) that will solve the problem I am having. Any suggestions would be very much appreciated!
Thank you,
Cheryl

replace the system drive
always clone your system
yes dump the 7300 if you plan to keep using it and use Lion
A clean install would be nice start, on say 120GB SSD or something too
And 2x2GB FBDIMM set is $30 if you need a set
AHT is on your OEM DVD from 20007
dust, temps and air flow is also important
