Mackbook wont log in past blue screen

i have a problem which wont let me log on past this blue screen. ive tried safemode and single user mode but nothing seems to work. this has happened before and somebody used firewire to update my system or something like that. please can u help me to get my computer up and running

Welcome to the fums Kiwi!
Tough to guess on the data loss, having a good backup or two is the only way to be sure... but disk Utility will not likely destroy something not alreadymessed up.
"Try Disk Utility
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."

PowerMac g4 wont turn on past blue screen

Hi all,
Ok, I have an idea as to what caused this problem but I don't know how to fix it. Back story, I had a "snoopy" friend come over the other night and in case they got on my computer when I wasn't looking, I wanted to lock everything so they couldn't access anyhting...instead of doing the smart thing and logging out...I had the bright idea to right click my harddrive and get info and lock the privelages tab and make it all say no access...well I tried to unlock it and it wouldnt do it and now I can't access anyhting on my own computer! Talk about the ultimate backfire....anyways, I restarted my computer several times and it starts up normally but stops at the blue screen....I can see the cursor and move it around but thats it. Please help!
Thanks!
Chris

Macbook Pro won't start up past blue screen

I'm running OS X 10.5.7 on my MBP, along with a boot camp partition. My superdrive has been playing up for the past few months, and upon learning that the 2.1 firmware update could be responsible, I obtained the update and attempted to re-flash the firmware myself. To do this I had to edit a system file and spoof my version number to 10.4.9; I couldn't flash the drive otherwise.
I used textwrangler to edit the file /System/Library/CoreServices/SystemVersion.plist - I had to unlock the file to do this. I saved it, used the flashing utility and rebooted as instructed, and then encountered the issue. The screen turns from grey to blue, and the "loading" indicator appears briefly before disappearing again - this happens repeatedly until I power my computer off.
I started up in single-user mode and performed a fsck - this repaired some filesystem issues I wasn't aware I had, but did nothing to fix the problem. Running in single user mode, however, did reveal that the loginwindow.app was crashing repeatedly, and crash reports were being saved in a log directory.
Attempting to start in safe mode results in it sitting on the loading indicator at the grey Apple logo screen for upwards of twenty minutes with no results (save my computer getting increasingly warm).
I've long since mislaid the discs bundled with my MBP as well as my Leopard disc.
Windows XP still boots with no problems.
What exactly is the cause of this issue? I wouldn't have thought the file I edited and not being able to get past this blue screen were connected. Is there any way I can restore it?
I also have a Macbook at my disposal - are there any feasible solutions which would involve booting another machine in target disk mode?

Did you make a backup of the file? Always a wise thing to do when messing with system files.
Not sure if pico works in SUM but it would be worth a try to edit the file again to revert it to its proper version. If that fails, you will need to get your Leopard disc for an Archive and Install. Might be able to get a replacement one from Applecare at little cost.
Good luck and let us know what happens.
Edit:
Just saw you have another Macbook available. If both machines were running same OS you might be able to copy the file from one computer to the other. I would do this as root though then run a Permissions Repair in Disk Utility afterward

Can't get past blue screen

I tried to reinstall Photoshop Elements from a disk and upon restarting to finish the install, I can't get past the blue screen after the grey Apple screen. I've tried booting into Safe mode and can get to the login screen, but when I log in, it accepts my password, starts the login process, but then loops back around to the login screen. Any ideas how I can get past the blue screen and some place where I can clean the offending application off my hard drive and reinstall the OS?

Incidentally, how much free space was on the hard drive? I am wondering if there's some kind of insufficient space issue here, especially after installing a large program.
Adobe has this [troubleshooting information|http://64.233.167.104/search?q=cache:qzZBfqgebGUJ:kb.adobe.com/self service/viewContent.do%3FexternalId%3D332811%22Photoshop+Elements%22+osx+systemfreeze&hl=en&ct=clnk&cd=2&gl=us&client=firefox-a] on their website. (I had to provide a Google cache link because when I tried to load the page using both Safari and Firefox it gave a blank page.) What version of elements are you using? I notice you said you were "reinstalling" elements, and the help page specifically mentions doing that. Not that any of this seems to indicate why your computer isn't starting except that maybe the Elements installer damaged something in your OS while installing. At this stage you may need to try to repair the directory using Diskwarrior or consider reintalling your OS (yes, I know, flaky disk, but...).

Mid 2010 MacBook Pro won't boot past blue screen

I've been having problems booting up my MacBook. I can't get past the blue screen. It went from booting slow at the grey apple logo screen to not booting up at all. Is it a problem with my hard drive? I also have boot camp running as well, but I can still see the boot camp drive for windows and my OS X drive, as well as my installation disk when I have it inserted when I hold the option key at start up.
I'm still able to run windows on it without any problems when I pick the windows drive. I tried different methods from different forums but I'm just not getting through. I tried holding 'c' to boot up from cd and I let it run over night but it never got past the grey apple screen with the gradient wheel (still spinning). I had already used time machine to back everything up before this happened since I was able to boot up properly (but slowly). Can anyone help? It's driving me nuts, and I can't remember what os/firmware version I'm running.

n your signature you said you are running 10.6.3. So let’s assume you are running Snow Leopard.
It sounds like your diagnosis of disk problems is correct. The OS X partition may be corrupt.
Try booting in Safe Mode.
http://support.apple.com/kb/HT1564
Try again to boot in normal mode.
If it will boot in Safe Mode but not in normal mode then you could have some 3rd-party software preventing the boot or you could have a corrupt disk or OS.
Boot as from the startup manager (Boot - option) and then select the installation disk.
Hopefully that will work better than starting with the Boot-C option.
Then try to repair the system disk.
Start the Disk Utility.
Perform the steps in http://support.apple.com/kb/PH5836.
If it repairs OK but still won’t boot reinstall OS X.

After software update, will not boot up past blue screen

I just did a software update and after restarting, the computer will not go past the blue screen with the spinning wheel at the bottom. Please help! I've tried everything under troubleshooting in the manual. Any other ideas?

Thanks, I was able to fix my problem. It was a software issue. Luckily I did a pretty good backup...I just forgot to back up 2 of my most used applications: iPhoto and Appleworks. They were on my laptop before I did the erase and install, and now they are gone. I thought they would be on the iBook install discs or the OSx software install disc...but no. They had to come from somewhere and I just cannot find them! I know I didn't pay for them. Any thoughts on where they may be? I am so mentally exhausted from these computer woes...I can't think anymore!!! Please help me!

Will not boot past blue screen

The present status is that my ibook g4 will no boot past the spinning wheel screen which hangs for a few minutes and then goes to the "Mac OS X" screen with the progress bar.
My first goal is to back up all of the data. I have a second IMac. Plus, I just purchased an external 500 gig hard drive just prior to when the error started. FYI the error started when I was going through the install process of the backup program supplied with the external hard drive. The program just asked me to restart the computer and that is where we are now.
The second goal of course is to fix the start-up issue. I have tried a number of the suggestions in previous posts including the following the install disk utilities to repair the disk.

I am having the exact same problem. I was just surfing the Internet this weekend and it completely froze and now it won't boot up. I no longer get a grey screen, at boot up, it goes from black to blue and then it hangs at the blue screen.
I have a TimeMachine and a Retrospect back up of my data but I can't boot to the Leopard Install CD which would let me restore my data.
I have tried just about everything, including booting in firewire target disk mode and connected to my old clamshell iBook G3. I was able to access my files, and I even reinstalled Tiger (couldn't use Leopard because it's not compatible with the G3). So there is a fresh copy of 10.4 running on my iBook G4 but it still will not boot up on its own.
No idea what to do at this point, but I would suggest not reformatting as it really didn't seem to help.

PowerBook G4 won't boot past blue screen

I've read a couple of posts with similar problems. The jist is, I did a security update/restart earlier and now my laptop won't boot past the blue screen after the white screen with the gray apple. I think I'm on Mac OS 10.4.11 but I had it on auto-update so that could be incorrect.
I've booted from the install disk and run a diagnostic from the First Aid bit in the Disk Utility. It says that there are no errors found and the S.M.A.R.T. status says "verified" as well. It won't let me boot into Safe Mode (although, I could be doing that wrong as I'm not exactly clear on how to do it - pressing S doesn't seem to do anything, but if I press Command + S it takes me to a text listy thing and I've run the "fsck -f" system check (which seems like the same as the disk utility check?) from there and also gotten the "volume is ok" message. There was also a suggestion to run some kind of diagnostic after booting with the D key from the install disk, but I was never able to get the disk to boot from the D key, only the C key.
I'm sure that this is kind of the "same song, different verse," kind of post, but I've not read about volumes registering as okay. I'm a little wary of a archive-and-reinstall as I've not ever done that before (so, if that's the suggestion you have, I would really appreciate loads of specifics on how that works so I don't mess up!)
I've read in several instances suspicion of a hard drive problem but I've not had any slow downs or any crashing. I did travel to the UK for about 10 days, but I didn't even change the time zone on my laptop while there, so I don't think that's it (but I suppose it could be.)
Lastly, I did recently replace my keyboard. A few keys had become non-responsive so I replaced it and have had the new keyboard for a bit over a month.
Suggestions? Ideas? Sorry if it's a repeat post -- just felt like the circumstance was a teensy bit different. And also, thanks very much for any info you can give.

Linsey:
If you can boot your computer into Firewire Target Disk Mode and you have access to a second Mac that supports firewire, you may be able to back up items that have not been backed up previously.
If you are able to back everything up successfully, and you have tested your backup to be sure it is sound, then we can proceed with re-installation of the OS. The best option is to completely reformat and erase the HDD and then install the OS from disk. (I will post complete step by step directions). This will enable you to start with a clean slate/HDD. Your other option would be to use the Archive and Install option. Think it over and let me know how you want to proceed.

MAC DUO won't go past BLUE SCREEN on start-up.

Please help!
My mac duo has crashed after a mac software update. Now it won't logon past the blue screen!
I've tried everything online like DISK UTILITY on Mac os x disc and SAFE MODE but no joy whatsoever.
SAFE MODE won't work now after doing it three times. Is this typical?
Should I re-install the MAC OS X using the option to copy existing files and applications?
Any help would be greatly appreciated.

There are two major problems out there right now. That is also part of the problem. We are not used to two problems in our domain.
I own 20 Mac's in my office, and I only did the latest updates on my MacBook Pro 17-inch portable and my G5 Dual 2.3 GHz desktop that has two 30-inch Cinema Displays. Both machines had the Adobe CS 2 Professional Suite with Acrobat Professional.
I had both of the prevailing update problems on my MacBook Pro—1) unable to restart and 2) Acrobat crashing the system.
On the G5, I only had the 1) unable to restart problem.
I won't update the other machines until these problems are resolved by the OEMs.
1) Unable to Restart. Of the two major hiccups out there, the link below indicates Quicktime's update is the source of the 1) unable to restart problem, fixed by deleting startup items, I believe. Again, I had this 1) unable to restart problem on both operating systems (PPC and Intel versions). Recovery of the 1) unable to restart problem is done in in Safe Mode by holding down the Shift key when restarting. This may take a long time to reboot, so keep holding down the shift key until the grey screen and startup wheel is seen. Then delete all startup items and Adobe Version Cue if you have it. (Use Version Cue Uninstaller.)
http://www.macworld.com/news/2006/05/24/cs2quicktime/index.php
2) Acrobat Crashing the System. Acrobat's freezing the entire OS 10.4.6 system is a result of the Security Update 2006-003, fixed by rolling back to a pre-Security Update state using Archive & Install for re-installation of the OS. Archive & Install does not erase your files or network settings. Printers may need to be re-added.
Apple has released two products (QT 7.1 and SU 2006-003) that fouled these systems. Bad Quality Assurance, I think. I am not sure if the Security Update problem is an Apple or an Adobe software problem, i.e., Adobe may have not followed some software guidance from Apple in Acrobat 7.07 or earlier versions. I am certain both companies are aware of the problem, but I am uncertain of the fix for Acrobat. We probably do need to update for security, but I can't live without Acrobat. So I will wait it out sans Security Update 2006-003.

HP dv9740us not going past blue screen with page_fault_in_nonpaged_area error

I have had very few problems with my laptop until recently. I have had a couple of minor crashes that I could fix by doing a hard restart. Last night, I was playing an online game and suddenly my game started to bog down then it froze up completely. I tried to ctrl+alt+delete to restart and nothing happened. So I ended up holding down the power button until it shut down. As soon as it started to reboot, it went into a black screen asking for start up repair or start windows normally. I tried repair, and it took me to the screen, did a little running of the program, then went black. When I was ready to hit the power button it flashed several windows in both blue and black and finally ended up with the blue screen telling me I had the page_fault_in_nonpaged_area error. I tried several things: restarted again, ran disk tests on both disks(passed), a memory test(passed), and am now backing stuff up to an external drive. It will not get past that error or that blue screen. Both my husband and I have decent experience with this kind of thing, but neither of us are able to fix it. I also tried to follow the instructions for reseating the memory. Nothing works. I don't want to lose my important files, especially all of the pictures of my son's first year. Please Help!!!
I want to add that I have not added any new programs lately. The only thing causing problems has been a PC Matic add-on to do real time protection. That stops working everytime I open windows.

This Stop message occurs when requested data is not found in memory. The system generates a fault, which normally indicates that the system looks for data in the paging file. In this circumstance, however, the missing data is identified as being located within an area of memory that cannot be paged out to disk. The system faults, but cannot find, the data and is unable to recover. Faulty hardware, a buggy system service, antivirus software, and a corrupted NTFS volume can all generate this type of error.

Old iMac was sluggish and now won't go past blue screen.

We have a pretty old iMac, it will be 7 years old next month. I totally expect for it to slow down and have issues being that old, but was hoping I could maybe get a few more years out of it for my in-laws. We gave it to them 2 years ago and now it's going downhill. It has been sluggish for quite awhile and now will not turn on past the blue screen. No spinning wheel, just a blue screen and an arrow.
Is there anything we can do? Could we perhaps completely wipe the computer as there is nothing important saved on there? Would that even help? We are probably at the end of it's life here, but just thought I'd come for suggestions first.

I suspec the machine has had a hardware failure. If you can run Apple's Hardware Test, you will need the original install discs that shipped with the computer to do this. Run the test in Extended Mode at least 2-3 times back to back. The reason to run it multiple times is AHT is not 100% reliable however if it detects an error the error is correct. If you get an error that means a trip to the local Apple Store or AASP for repair, based on the vintage of the machine I woudl recommend an AASP. If you are aware of AHT then please click Apple's instructions located at:
Using Apple Hardware Test
Good luck!

Hp dv6t won't go past blue screen blinking cursor

Hello,
Please help me figure this out! I have looked at the boards for days and weeks but cannot solve my problem. No matter what i have tried so far, I cannot get past the blue screen with blinking cursor. A couple months ago I was out of town and blue screen came up i was able to hit F4 rapidly and eventually get it to work several different times that trip. Now however, I cannot get anything but blue screen and blinking cursor. Thanks in advance for any help! Heidi

Hi @heididmn1800000,
Welcome to the HP Support Forums!
I am sorry to hear that you cannot get passed a blue screen on your HP dv6t PC. I will try my best to help you with this. To better guide you, could you please tell me the full model or product number of your computer and the operating system that is running on it. Here are some guides for How Do I Find My Model Number or Product Number? and Which Windows operating system am I running?.
In the meantime, here is a document for Troubleshooting Error Messages on a Blue Screen that may Occur During Startup or Boot, that may have a solution for you.
I hope this helps, please let me know how it goes.
Thank you and have a great day!
I worked on behalf of HP.

Cant get past blue screen

I've tried all the troubleshooting options on the site and none have worked so far. My computer will not start up in safe mode. I get past the gray screen with the apple logo. But when i get to the blue screen, it just goes from dark blue, to light blue, and back, forever. at one point i left it on all day to see if it went anywhere, and it did not. So safemode doesnt work, and there is no way for me to get into my computer at all. Beyond frustrating. If anyone can help, I'd be much obliged, because I want to catapult it out the window.
thanks

It sounds like there is a problem with the OS on the hard drive. Try starting the MB from the DVD that came with it. Then you can run Disk Utility from the DVD and see if it can repair the HDD.

Can't log into account, blue screen

I shut down my computer earlier, and when i booted back up a couple hours later I cannot log into my main account (the admin/first account created). It goes to a light blue screen, and the cursor on screen responds to my mouse, but it just sits there until finally jumping back to the login window. I have tried disk permissions, shutting down, tried safe boot (but can't seem to get to the safe boot login window). I can log into the 3 other accounts fine, and can access everything through command line from in one of those accounts so at least my data is ok (also backing up time machine to an external) but I really don't want to reinstall the entire OS. I don't understand how this even happened, as I didn't do anything any differently than normal. Is there any other trick that I haven't stumbled across that might fix this? I want to make sure that I don't jump the gun if this has happened before and is easily fixed.

Well I did a silly thing - I installed the Unsanity APE on Leopard 10.5.2. A beta. And a warning.
Did I care? No, betas just mean uninstalling if they don't work right? Nope.
I go the interminable blue screen, couldn't login, couldn't solve it via Terminal. All I deserved! How you mock me with your betas. HOw I mock myself by using RAID 0 for speed. Luckily for all my reckless grappling with the latest thing and an obsession with speed, I use Super Duper Drive clone, idisk and mail backups weekly - So I was up and re-installed in a couple of hours. But oh dear me, what a lesson to learn.
SO, perhaps you did do something insignificant that caused it to fall over and blue screen, and perhaps APE didn't cause my problems - But I can't recall having so much trouble with any previous OS X release ever. In fact I can't ever remember having any trouble since 10.0.
No matter, I have decided to use a test machine for meddling with stuff now, and leave my MacPro eating the food it knows and loves without 3rd party additives. And I suppose - That's fine too.
And then last night I caught myself looking at some hastily written 3rd party Ati graphics drivers and wondering if that might be an idea. And then I threw a bucket of water over my head and calmed down again.
We probably did something to muck up our systems, I'm just glad we have archive and install, CCC, Super Duper and all the other safety nets that doesn't make using a MAc like the heart stopping use of a PC when you're just faced with a completely broken machine and nowhere to start.
Oh, and no it doesn't answer your question, just a ramble in terms of forum solidarity.
