I am having issues with my 13.3" MBP, blue screen on boot up?, cannot figure out why? If I log in as another user(from my older macbook) it will boot but I cannot get to my newer files and docs. Any thoughts?, it appears to be a permission issue as if I boot up as a target disk using firewire, the files I want to access are still on my hard drive.
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of this exercise is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login. Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode* and log in to the account with the problem. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
*Note: If FileVault is enabled under Mac OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
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(s)?
After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test. -
Blue Screen and Sound Problems, In Desperate Need of Assistance
About a week and a half ago, my computer officially stopped showing anything on the display when I tried to start it up. It had been doing it on and off for a long time, but I would eventually get it to display. Not this time...
My husband and I took our 30" Cinema Display and G5 tower to the iStore. The display was tested, and it worked fine. The associate said the problem was the video card.
After doing much research, I decided upon the flashed GeForce 7800 GS, per the suggestions of japamac on this forum. After I received and installed it, the display worked again and everything seemed great! It came with a CD with a patch on it, saying it was for *10.4.9 or later*, so I installed the patch and ran the permissions command. I had to go on a business trip immediately as the permissions command was running, so I left the computer to do it's thing, knowing it would sleep after a while.
When I got back home from my trip, I eagerly hopped on my computer. I attempted to awake it from sleep, however it froze. I was not able to tell if the permissions command ever finished completely.
I restarted the computer and everything seemed fine. A few hours later, my husband hopped on the computer about to test the new card on a game, but it froze before he could do anything. We restarted the computer, and that's when the blue screen issue started.
I tried resetting the PRAM, starting it up on the install disc (which didn't work), I tried holding down the S key (which also didn't work), and I tried holding down shift for Safe Boot.
The Safe Boot works, in fact I'm on my G5 right now. I did the permissions command again, thinking that it must've not ran all of the way and the permissions were broken. When it finished it gave me a massive list of "permissions differ"s with 10 "Warning: SUID file "____" has been modified and will not be repaired" messages at the end.
I contacted the seller on ebay, who ended up telling me the patch was only for Tiger, despite the file saying "or later". I really thought I messed up the permissions badly from that and tried running the permissions repair, but that did not help.
Thinking I had no other choice, I backed everything up and I reinstalled Leopard (choosing to Archive). After it finished reinstalling, the computer restarted and it booted up normally. I thought my problem was solved! However, once I let it sleep and came back later, it was frozen. I restarted and had the blue screen problem all over again, to my disappointment.
I tried restarting, the PRAM, the permissions (which did not list those SUID warnings anymore)... There was once that I restarted and it gave me the blue screen, I tabbed twice, hit enter, and entered my password though I couldn't see anything. I heard the computer moving like it was logging in. I pushed the power button on my display, and magically the screen displayed my desktop with the "Are you sure you want to put your computer to sleep?" window.
However, this only happened once, and afterward I noticed an issue when I tried to wake the computer from sleep. It would try to wake up, then go back to sleep, try to wake up, go back to sleep... So I contacted the ebay seller again, explaining what had happened and that it made me think it is an issue with the card itself, not permissions. (Fearing that if it is permissions, I would have to reinstall the OS again, but choose to erase the disk this time.) I asked if the seller knew anything about this.
The seller contacted me back saying, "Hello again, yes, wake from sleep is a common issue of many modified cards for Mac , so you better turn it off if you are not use it, its better for both the video card and power supply of your G5,
hope you understand about it , thanks". Well, that really would have been nice to know in advance... but regardless, the more important issue is the blue screen on startup.
On top of all of this, when I tried to watch a video tonight I noticed the sound was not working. I made sure it wasn't muted, I made sure the optical cable was connected, nothing. I restarted, nothing. I did not have any problems whatsoever with the sound before this, and I'm not sure if it has anything to do with the card (I wouldn't think so), or that something needs to be reinstalled since I reinstalled the OS. The System Prefs > Sound, Is not finding any devices.
I've restarted the computer so many times since the initial failing of the video card, I really hope all of the restarting hasn't damaged anything. As old as my Mac is, it's been working perfectly normally until the graphics card went out. After that, it's seemed like everything is falling apart. Thank you for reading my long history of difficulties, and I hope someone (maybe japamac?) can help me!Hi-
I understand why you would suspect the latest hardware addition, and the conflicting/misunderstood advice given by the seller isn't helping.
I don't know of any cards that have "known" issues with sleep from the flashed realm.
Of the 10 different makes and models that I use or have used, flashed by myself or others, I have never seen an issue with sleep.
This includes 2 different Geforce 7800 GS cards.
The most common reason for a blue screen at boot is an incompatible Login or Startup item.
These are disabled during a Safe Mode boot.
http://www.thexlab.com/faqs/startupitems.html
As for the Geforce 7800 GS, there was a patch for OS 10.4.9 only. This was to allow for the proper reporting and use of the appropriate OpenGL engine.
After 10.4.11, and in Leopard, the OpenGL engine is properly selected for the card.
Since this is simply a reporting issue, and not a performance issue, the patch is not a mandatory thing.
There is an issue with the ROMs used in some Geforce cards that causes a boot delay (a blue screen) for up to 6 minutes.
Most guys don't use those ROMs anymore, but I guess that someone may not have bothered to get the new ROM.
Removing the AppleHWSensor.kext from /System/Library/Extensions will correct this issue.
This, however, is historically a G4 issue only.
There are a couple possible scenarios that I think may apply to you:
1- The card is overheating, thus the occasional success or Safe mode only boots.
Check that the fan is spinning.
2- The auxiliary power is not connected, or has a poor connection.
Sometimes the pins on a Molex adapter (the female side) are so tight that they push out, rather than allowing the male pin in.
Conversely, a stretched out female pin would not properly contact the male pins of the graphics card.
Double check connections at the optical drive and at the graphics card.
While inside, reseat the graphics card.
3- If the card was prepared for use in a G4 by cutting the traces of pins #3 and #11, this can cause problems in the G5.
Most cards work fine, but some Geforce cards complain.
As well, if the pins were taped, the tape should be removed for use in a G5.
http://themacelite.wikidot.com/pins-3-and-11
If the traces are cut, return the card.
If the pins are taped, remove the tape. -
After getting the dreaded gray/blue screen, I tried to run disk repair on the internal disk. I got an error message saying "Disk Utility can't repair this disk and restore your backed-up files. The volume Macintosh HD could not be verified completely." What do I do now? This is an iMac and I'm running 10.6.8.
Clean Install of Snow Leopard
Be sure to make a backup first because the following procedure will erase
the drive and everything on it. See below for how to clone a drive.
1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
with your computer. Insert the disc into the optical drive and restart the computer.
After the chime press and hold down the "C" key. Release the key when you see
a small spinning gear appear below the dark gray Apple logo.
2. 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 the hard drive entry from the left side list (mfgr.'s ID and drive
size.) Click on the Partition tab in the DU main window. Set the number of
partitions to one (1) from the Partitions drop down menu, click on Options button
and select GUID, click on OK, then set the format type to MacOS Extended
(Journaled, if supported), then click on the Apply button.
3. When the formatting has completed quit DU and return to the installer. Proceed
with the OS X installation and follow the directions included with the installer.
4. When the installation has completed your computer will Restart into the Setup
Assistant. Be sure you configure your initial admin account with the exact same
username and password that you used on your old drive. After you finish Setup
Assistant will complete the installation after which you will be running a fresh
install of OS X. You can now begin the update process by opening Software
Update and installing all recommended updates to bring your installation current.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You may be able to backup your data if you have an erased external drive you can use. Before you do the above but after you have opened Disk Utility you can try to clone your drive:
Clone using Restore Option of Disk Utility
1. Open Disk Utility.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Select the destination volume from the left side list and drag
it to the Destination entry field.
5. Select the source volume from the left side list and drag it to
the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
Now this will only work if the drive is accessible and can be cloned by Disk Utility. Otherwise, you would need to access your drive from another Mac that you can connect via Firewire - Target Disk Mode. -

Persistent blue screen of death problems on Toshiba laptop pc; need help
hey, guys,
I was hoping you could help me out here. I have been experiencing persistent blue screen of death problems on my Toshiba laptop since December 21 of 2014. The first two times I started having theses persistent issues, I downloaded a bunch of redundant programs and games onto my computer, some of which were virus infected. I had these programs on my computer for a while before my laptop was taken in for repairs. I eventually uninstalled some unnecesssary programs from my pc, hoping it would have fixed these issues, even tried windows update. I didn't have a clue that my problems were due to virus infections/malware until the two most recent times my computer was taken in for repairs; I had always been thinking it was a defective driver. My laptop has already been in for repairs at least twice due to these perpetual BSOD problems; I had Norton Internet Security installed on my pc before the Geek Squad team (who repaired my computer and found 312 traces of malware in my system during the virus test; I was told by them that I had mistakenly downloaded infected web browsers onto my pc) switched me to Webroot SecureAnywhere (they said it was better at detecting viruses/malware than my NIS), but even after my pc has been through repairs twice in a row, I am still experiencing blue screens (this only seems to have happened once each week, and on one occasion, I went through almost two weeks without it occurring). I am pretty sure, that I haven't downloaded anything onto my computer infected with viruses/malware (each of the scans done by my Webroot antivirus have found nothing), I have only a few games/apps installed on my pc, and what I downloaded all came from Microsoft's official website. I can't afford to be wasting any more money on repairs, and I am desperately searching for any possible way to fix this myself. Any help would be appreciated. I have a copy of two of the memory dumps from my most recent crashes (I also have the dump reports from my most recent crashes dating back to March 6; I got these from an app from NirSort called Blue Screen View, if you need those) I also have my system specs:
http://1drv.ms/1I6AsaE
http://1drv.ms/1Qdsb7T
Note that many of these earler dump reports (the ones from March) came from viruses. The ones from most recently as last month, I am not sure about.

Thrashing about this way gets us nowhere.
Best to restore the hard disk to its original out-of-the-box contents.
Settings > Change PC settings > Update and recovery tab > Recovery tab > Remove everything and reinstall Windows
Use the freshly restored machine for a day or so before any installations of hardware, software, or updates of any kind. If you get no crashes, the problem is not likely due to hardware.
Then add updates and other things slowly, keeping track of them. If you get crashes after that, give us the corresponding dmp files.

X200 with OCZ ssd blue screens when booting from docking station
The x200 blue screens when booting from the docking station. If I take the laptop out of the docking station to boot and then dock once booted the laptop is fine.
The issue started happening when you I upgraded the laptop form xp to windows 7 and installed an OCZ vertex 2 solid state drive.
I have tried updating the firmware on the ssd using this utility
http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-69806
The program showed that my ssd was running firmware version 1.29 and did not need to be updated.
I have also tried updating the x200 to the latest BIOS. Nothing seems to work.
Any ideas or suggestions are greatly appreciated.

Big problem with plain blue screen on boot (not related to Leopard install)
Hi - eventually I have worked out how to post to this forum!
I have had a major disaster with my iMac this weekend. It began with a lock-up when I was working happily away in Blender. I got a beachball and the machine froze. I had ssh set up so I tried to go in from my iBook to kill a few processes to try to get it back on track, but without success, so eventually I had to hold down the power button to power off the machine.
When I tried to reboot, I got the grey screen and the spinning wheel, then a plain blue screen with no mouse, no beachball and the machine just seemed to stop. I could hear the CPU going like the clappers and was able to ssh in again and check top to see what was going on, and the WindowServer(?) process was maxed out at 100%. I wasn't able to kill it and again nothing happened and on a further reboot I just had a plain blue screen.
I have since spent a few hours trying various things to sort this out, so far to no avail.
- Single User mode, fsck -fy: reports everything fine, no change
- Reset PRAM, no change
- Tried booting off my backup Firewire drive (SuperDuper) but it won't boot to it, same blue screen hang
- Ran Disk Utility from Leopard Install DVD - permissions, checked disk, etc - no change
- Ran DiskWarrior in Target Disk mode from iBook, no change
- Ran Tech Tool Deluxe, no change
- Removed RAM (not third party), put it back in, no change
- Reinstalled Leopard using Archive & Install, no change
- Reinstalled Leopard again, using Erase & Install, no change
- I think I'm running out of options.
I'd have been on the phone to Apple by now but it's Sunday tomorrow and a Bank Holiday in the UK tomorrow so it will be Tuesday at the earliest, and I know I'm going to be frustrated by having to go through all this with them again!
A weird thing is - I CAN get logged in in Safe Mode now and again, and when I do, the mouse pointer has a small, almost transparent rectangular graphic attached that follows the pointer around. Barely perceptible but it's there - it looks like a Leopard icon for a txt file but barely visible. Has anyone ever seen anything like this?? It really feels like something has corrupted, but with a totally clean OS install, is that possible?
As it stands, I'm sure this is a hardware issue but I'm not sure. I had a couple of power outages lately which I suspect are behind this.
I'd be really grateful for anyone's thoughts on this - it's been a really frustrating couple of days.
Cheers.As far as I can see, resetting the power manager on this model of iMac involves resetting the SMC, which is unplugging all cables for 15 seconds, plugging back in and powering up. Tried that too, same result. In terms of third party software, nothing. Clean Leopard install is the lot.

Stuck on dark blue screen on boot up Macbook Pro
I was opening emails and my computer froze and a dark blue screen came up with no words. Then I tried rebutting in safe mode, while holding command r, and in recovery mode. Nothing will boot. Every time the computer gets past the gray screen with the apple logo it goes back to the dark blue screen. I was able to use a lightning cable to get the data i need off the computer in target mode. Any ideas?
How full is your HD? I had this same problem and the Genius Bar guy thought that the lack of space on the HD led to file corruption during virtual memory swapping. After deleting ~10 GB of files (backed up, of course), I re-installed the OS from the install disk and everything seems fine now.

HELP! iMac G5 hangs at blue screen, but boots in Safe Mode
Please can anyone guide me to recover my iMac G5 PowerMac 8,2 running OS X 10.4.11.
Problem; Mac hangs on start-up at blue screen after grey Apple screen. Mouse pointer eventually appears but that is all.
Actions taken so far without success:
1. Disconnected the printer and rebooted - no success.
2. Booted in Safe Mode - first time the screen was completely scrambled but with safe mode log on screen showing through.
2.1 Rebooted in Safe Mode OK This has not occurred again and I have entered Safe Mode twice more without problems. But worrying!
2.2 In Safe Mode I ran disk Utility and verified and repaired Permissions, mostly old EpsonPrinter files.
2.3 I also verified the Disk, which was reported OK.
2.4 I was able to save critical documents to USB............ Phew!
2.5 Reboot in Normal Mode - no success
3. Reset PRAM
3.1 Reboot in Normal Mode - no success
4. Reboot in Safe mode - works fine. NOTE: time and date appear to be correct and dont need resetting.
4.1 Run Disk Utility again and Verify Permissions - OK. Nothing needed fixing.
4.2 Run Disk Verify - Passed OK
4.3 Reboot in Normal Mode - no success. Hangs at blue screen with mouse pointer visible and working. Then pointer vanishes.
I would be most grateful for your help in moving this forwardGot to figure out which which of the things dropped when you boot in safe mode is causing the problem.

Qosimio G30-116 with blue screen on boot
I have a Qosmio dule boot Qosmio G30-116, booting in windows generates a blue screen of death, which is quickly cleared before I can read what is displayed.
Boot it in windows safe mode results in a long list of files being displayed the last one being Mup.sys
Booting the machine in Linux and running everything that I can think off does not generate an error.
Running the on board Toshiba dignostics from the BIOS does not generate an error.
Running the linux memory check does not generate an error.
Viewing the file system does not generate an error.
So I don't think I have a hardware problem, I think something is matter with windows
Does anybody have any idea how to stop my clearing the screen so I can actual find out what the problem is ?
There is a lot of valuable software on this machine, I have no desire to trash the entire disk to attempt to repair what seems to be a specfic windows problem.Hi,
I am sure its not a hardware problem. Its a pure windows related problem but its like one of these bluescreens which try to tell you that your memory is gone. :(
First of all, try to remember which software youve recently installed. Which drivers were updated and how many microsoft KBs were automatically installed.
I would really recommend you to google for "Mup.sys" and check the site "hardwareanalysis" which is the second entry when searching for that term.
This problem has many reasons and there are many different solutions..because the reasons are so different. So, if you want to keep your "valuable" programs and dont want to reinstall your system (what could be btw. the easiest way after backing up your "valuable" software) then check the forum Ive suggested and you will find hopefully the enlightment.

Blue screen when booting from USB drive in UEFI mode (2013.07)
SOLUTION for me was to update the firmware on my ASRock mb as thatu pdate changed the EFI software (by American Megatrends) version from 2.00 to 2.31. However, other users are still experiencing the blue screen.
SHORT VERSION
When I try to boot Arch Linux 2013.07 with an USB drive in UEFI mode (for installation), I get a blue screen (which is rather a literal description and not a hint towards the old Windows' one) with the message
Failed to install override security policy (14): Not found
LONG VERSION
I made an USB installation media (product: Intenso Rainbow) by following this advice on the wiki.
I used the july release of Arch for that. First of, after installing the image to the USB stick I found that I needed to correct the label in the archiso-x86_64.conf file to ARCH_201307 (or was it the label of the usb stick, can't remember right now). (Pretty sure it was the same problem with "Linux Live USB Creator" which I used 3-4 months ago...)
After doing that, I rebooted and selected the entry
UEFI Intenso Rainbow
from this list of entries:
SATA HDJ ... something (the hard drive where Win 7 64 bit is installed with all programs)
SATA something (hard drive which only contains data)
Windows Boot Manager
USB: Intenso Rainbow
UEFI: Intenso Rainbow
It went to a blue screen with a message in white text saying
Failed to install override security policy (14): Not found
Below that was an OK button which had a black rectangle over it.
After I experienced the bluescreen, I tried booting the
USB Intenso Rainbow
entry and the boot process then worked fine, I got to that Arch menu where I could choose
Boot Arch Linux (x86_64)
Boot Arch Linux (i686)
Boot existing OS
Run Memtest...
and so on...
But just to make sure, I then did the check for UEFI mode according to this and only saw a folder acpi and ... something else I can't really remember, but it definitely was not efi. Thing is, I needwant to boot into UEFI mode as I have Win 7 already installed in UEFI mode.
Some info about my motherboard: it's from ASRock and is called H67M. The BIOS is dated to 2011-10-26 and is version 1.7.
So far, I only found a mention of the problem here at superuser.com.
Last edited by jones (2013-07-15 07:15:18)Ok then, so this thread has also become about the blank screen problem when booting (in this particular case, Arch 2013.06 since 2013.07 seems to be worse).
srs5694 wrote:Typically, you adjust kernel boot options using your boot manager or boot loader. In GRUB, you hit the "e" key to open an editor. In rEFInd, you hit F2 or Insert twice. I don't recall offhand what key does the job for gummiboot (which I'm pretty sure the Arch installer uses), but I'm certain it's got the feature.
You are right. Thanks. I realized I had the gummiboot config right in front of me all the time. It's the file 'archiso-x86_64.conf' in \loader\entries (on Windows).
An addendum: I think the USB: Intenso Rainbow boot option takes me into a GRUB menu. Hitting 'e' in this "big" and fully designed menu didn't do anything IIRC. Hitting 'Tab' did the trick to get into editing the boot command line.
Hitting 'e' worked in the gummiboot menu though.
So I tried booting with the following options (also by combining some of them)
nomodeset
acpi_backlight=vendor
radeon.modeset=0 (I have a Gigabyte 7870 card in this desktop machien)
i915.modeset=0
but it did not help.
To be rather safe than sorry: I should mention that there are two grey-ish bars visible on the top and bottom of the screen after I try to boot the first entry, Arch Linux archiso x86_64 UEFI USB. Always has been with those two older Arch version (2013.05+2013.06). I also found another thread where one user talks about using the VGA port of the monitor, which I am currently not, I am using the DVI one, so that's worth a try too. EDIT It did not help either. What I did was setting the primary graphics adapter in the UEFI north bridge configuration menu to 'onboard' which worked immediately when rebooting (I hit the button labeled "Source" on my monitor and it showed it is using the "Analog" mode), but the problem just stayed the same. Adding aforementioned boot options or a combination thereof did not change anything.
Thanks for the e-mail addresses, I sent one to James Bottomley.

Hanging on blue screen during boot (but Safe Mode OK)
Strange stuff with my iMac G5 -- machine boots normally, gets through Apple icon and spinning spiral, then hangs on blue screen and stays there. Mouse cursor moves but that's it.
Safe boot works normally, all safe-mode functions good. But need network, other services back.
History: Spent most of past week downloading huge, multi-gig file. It eventually downloaded successfully, but during process my wife put computer to sleep a couple of nights without halting download.
Didn't have adverse effect first time, but it froze Finder second and third times, necessitating reboots. Also killed wireless connections for all PCs in network those two times iMac needed reboot, had to reboot gateway as well.
Morning after download finished (Friday), iMac failed to wake up from sleep, wouldn't boot normally, had to go into Safe mode.
Additional RAM was recently installed, but has worked well. Safe mode shows full two gigs in use.
Solutions I've tried, without success:
-- Trashing network preferences in both user and system
-- Re-installing Finder and NetworkInterface apps using Pacifist
-- Removing recently installed extensions in System (extensions put back after that failed to resolve issue)
-- Removing recently installed Startup items (again, put back after that failed to resolve issue)
Clearly it's got something to do with the network interface, but I've tried everything I know how to do. Any ideas? I'm out of them.
Thanks in advance.The Airport card is not removable in this model -- 2nd rev G5 iMac, with automatic light sensor.
But -- I think I've found what's wrong. Unfortunately there's no easy fix ...
It's most likely the bad-capacitor issue that plagued the 1st rev of G5 iMacs. (This particular machine was a refurb bought direct from Apple in the fall of 2005, so it's possible bad caps were put on during the refurbishing.)
I first heard about the problem a couple of days ago but figured a hardware diagnostic test would catch it. More online research reveals that the hardware test doesn't.
When I popped the case this morning to yank the new RAM, there were definitely a few capacitors that had domed tops. Nothing spilling out anywhere, which was what I was looking for, but I've since found out that even contained bulging is a sign of failure. The capacitors should be instead perfectly flat-topped.
So ... I'm gonna call Apple tomorrow morning and see how much it would cost to replace the mobo. There have been reports in forums that Apple sometimes offers to do it for free, even in cases occurring within the few months.
See this link for examples of Apple picking up the tab for complete mobo replacement: http://www.macosxhints.com/article.php?story=20090314071508354
If that offer isn't made, I will look into having the capacitors replaced. This is at the edge of my own technical abilities so I will first ask my techie friends if they can do it for $100 or so, plus parts ... and if not I'm gonna try to do it myself.
This guy shows you how and sells inexpensive parts to do it with: http://jimwarholic.com/2008/07/how-to-repair-apple-imac-g5.php
There is also a guy out in Missouri who replaces bad capacitors on motherboards for a living: http://www.badcaps.net/ Looks as if he'll charge between $80-120 including shipping and parts. So I may go that route.
In any case it turns out Apple did know about this issue back in 2005 and even instituted a program to fix iMacs that had problems stemming from it for free. (Dell Optiplex machines also had the same problem, which was traced back to a few Taiwanese manufacturers.)
Unfortunately there was no recall (Apple would never have lived that down) nor was the issue highly publicized. You had to wait until your own machine acted up, and then the free-repair program expired at the end of 2008.
I myself never knew about it until a few days ago, and I usually keep up on this stuff -- which is something I will make very clear when I'm on the phone with Apple tomorrow. -
Blue screen - after booting into Darwin/BSD
Hi,
after I had the problem of my iMac G5 only booting into Darwin/BSD (which I posted here: http://discussions.apple.com/thread.jspa?threadID=1093517&tstart=0), I followed the instructions for recreating the user accounts, as described here: http://discussions.apple.com/thread.jspa?threadID=320663&start=0&tstart=0
Now I'm able to get to the blue screen, and the system doesn't exit into Darwin/BSD any longer. However, the Setup Assistant doesn't start either.
I only see an empty blue screen (I guess it's the GUI base screen) and the menu bar. The menu bar only has to items: one menu 'loginwindow', which doesn't have any entries. And the Apple-logo menu, which has the following menu entries:
- About This Mac
- Software Update...
- Mac OS X Software...
- System Preferences...
- Dock >
- Location >
- Force Quit...
- Sleep
- Restart...
- Shot Down...
- Log Out System Administrator...
The 'Restart...' entry doesn't work. I can, however, launch the System Preferences window.
Tail command of /var/log/System.log shows:
configd[41]: WirelessConfigure: 88001003
kernel[0]: Registering For 802.11 Events

Any recommendations on what to do next?
Thanks!
TorstenApologies, was a little vague. and as far as my profile goes i have loads of mac's here in the studio.

2. shut down windows and re boot in OSX
