Blue Screen no mouse

I have a G4 1GHz flat panel iMac running OSX 10.3.9. Earlier I had a kernel panic. Upon rebooting, the screen goes from the apple screen to a blank blue screen. No mouse, can't open up the disc drive.
I tried starting it in safe mode. When I try that the wheel merely spins a little longer and freezes without getting to the blue screen.
I then tried to start up in single user mode to use fsck. I was able to do that, but fsck was unable to discover any problems.
Is there anything else I can do?
Thanks.

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 forward

Got to figure out which which of the things dropped when you boot in safe mode is causing the problem.

Blue screen: my G5 fails to boot normally, only in safe mode

Greetings,
After a power failure my iMac G5 started to behave quite odd.
That is, when I saw the computer was off, I pressed the power button, and it turned the coolers on and showed a screen filled with colored "snowflakes" (like one an untuned TV set shows, but static).
Curious, I forced it to restart, which ended in my current problem: +it boots, shows me a blue screen with mouse arrow in topleft corner, and this is it.+
Interesting is that when I move the mouse the cursor doubles: one arrow stays in its original place, and another one moves around the screen. Five minutes (or so) later the second arrow turns into a spinning beachball. After the blue screen appears there is almost no disk activity to be heard.
My next move was to try and boot from the Leopard DVD, which took much longer as it should, but ended in exactly the same way.
After that I tried safe mode, and here at last it worked. TechTool Pro's full disk check (including surface test) did not show any problems.
Reading the logs does not provide any clues to the problem. Everything is pretty much the same; I suppose it's just I don't know which log and where to read.
(By the way, I don't have the Application Enhancer which can cause a similar problem)
Any ideas on what's going on and how to deal with it will be very appreciated.
Thanks in advance!

There may not be a problem with your disk, but there certainly could be some problems with your file system. If you have or can borrow a copy of Disk Warrior, I'd use that to rebuild your directory with a new one; it will probably show a lot of problems in the report.
If you can't do that, then at least if you're in Safe Boot mode, the first thing I'd do is Repair Permissions, and then Verify Disk. If the Verify Disk report shows serious problems, you'll need to repair those before you can get a normal working system again. You should also try rebooting with the 10.5 Installer DVD again to see if it will let you boot, after you Repair Permissions and Verify Disk; if so, you can use Disk Utility from the DVD to repair your disk.

During installation of Windows 8.1, I get blue screen and can't proceed any further..

I'm trying to install Win 8.1 via Bootcamp 5.1 on my late 2012 3.4 i7 iMac. I'm installing from a Win 8.1 OEM DVD using an optical drive.
The partitioning process is fine, I have the latest windows support software on an MS-DOS (FAT) USB stick.
The install seems to be going fine, then up comes a blue screen (with mouse functionality) but no prompt/warning/error messages.
At this point I have no other option to restart and when I hold down the al key on start up, the Windows partition is not available.
Any ideas anyone?

It looks like that the installation process of one of the applications have caused some trouble. One of them may have changed or added kext files.
For that, the Window server crashed if you try to open a non Apple application like Firefox
Start the system in safe mode by holding the shift key on power on.
If save mode is reached, perform a permissions repair with the Disk Utility.
Don't bother about upcoming warnings like "could not repair file xy" as that occur cause you use the tool on a running system and opened files can not get touched by the tool.
After repair is done reboot system to normal and try to open Firefox.
If the problem persits, please report back here.

Blue screen and no login at start up after 10.6 install

After installing 10.6, I am not able to log into my MacBook Pro, unless I do so in safe mode.
I get passed the grey apple/boot up screen, then rather than having the list of users, I just get a blue screen (the mouse is there).
I have tried the following:
1. Booted from external drive and repaired permissions.
2. Logged into safe mode and deleted all start up items.
3. Reset the PRAM ect.
4. Removed all items from the "startupitems" folder within library.
5. Tried fresh install.
Any other suggestions?

Hi acl2009 & welcome to discussions.
1. Booted from external drive and repaired permissions.
Not recommended if that happened to be an older OS version - only use the version of Disk Utility that comes with SL. Boot from the installer DVD and use DU from there.
Any other suggestions?
Take your laptop and your SL DVD into the nearest Apple Store and ask the staff there for assistance...

Blue screen after installing

Hi,
I have a PowerPC G5 that I need to install Tiger, erase and install on the mac HD reboots a nd I get the a blue screen and mouse , that it.
Help...
Thanks
Martin

If you hold the Option/alt key at bootup do you get boot choices?
Does it boot into any of these modes?
Holding Option/alt key at bootup.
Holding SHIFT key at bootup.
Target mode...
http://support.apple.com/kb/HT1661
Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
/sbin/fsck -fy
Repeat until it shows no errors fixed.
(Space between fsck AND -fy important).
Resolve startup issues and perform disk maintenance with Disk Utility and fsck...

IBook G4, stuck at blue screen

Apple ibook G4. OSX 10.4.2
1.5 GB RAM, 512 on board, 1GB Apple RAM.
1) Blue screen at login.
2) Will boot into safe mode and works stable.
In safe mode, I was able to backup all items cared about.
After peeling back many layers of testing, including and archive and restore, I arrived at erase and install. So now I have a clean OS. No drive errors, No OS9 install.
Booted once to login screen.
Now, boots only to blue screen before login with mouse.
Safe mode works.
This configuration was my last 10.4 config:
Ibook G4 OSX 10.4.2 1.5 GB RAM, 512 on board, 1GB Apple RAM.
• Fresh from disk install of 10.4.2
• No Disk errors. Fsck = OK Disk Util from CD no errors, No permission errors.
• AHT = OK no errors.
• Will not boot to login, get blue screen and mouse.
• Will boot to safe mode.
• Creating second user and setting 2nd user autologin, or ask for login does not fix problem.
• Neither user password users high ASCII characters.
• Verbose mode rolls through, stops at same blue screen.
• Single user mode
o Time/date is off by one hour.
o Directory service loads, sees Ethernet link (or fails if disconnected), sees wireless, fails to load initCardWithStoredPrefs (no profile has been configured), AFH is supported. Ntpudate[73]: no servers can be used, exiting System stops and hangs here. Restart boot hangs at starting printing services.
I currently have this config:
iBook G4 OSX 10.5.8 1.5GB RAM, 512 on board, 1GB Apple RAM has been removed and reinstalled for testing.
• Fresh from disk install of 10.5.2 retail copy.
• No Disk errors. Fsck = OK Disk Util from CD no errors, No permission errors.
• Will not boot to login, get blue screen and mouse.
• Will not boot to login, gets stuck at starfield background, no dock
• Will boot to safe mode and works great and stable.
So problem is ?hardware?? Where do I go next? I am out of ideas.
Ken

Hi kleach,
Have you tried using Smart Utility to check your Hard Drive? If not, I would give that a go:
If your Hard Drive is failing it will let you know. Smart Utility looks at the mechanics of your Hard Drive differently than Disk Utility examines the directory structures. You can download a free trial version.

After you run the short test, try using the long test and examine the report.
Good Luck,
Randy

G5 2.7 boots to blue screen

all this happened while exporting video from final cut pro to a firewiree lacie drive. the machine went to spinning wheel for hours. had to reboot. Now boots makes the chime shows the os loading then goes to a blues screen with mouse pointer that you can move nothing elese is there.
I have to reset on the motherboard. booted to another machine and run disk utility.
still the same.
Any ideas ??

Start up the computer in Single-User Mode.
Check the volume with fsck.
Press Return.
Type: mount -uw /
Press Return.
Type: cd /Users/[affected username]/Library
Tip: Instead of "[affected username]", type the username for your account, or the account that is experiencing this issue. For example, if the username is "theta," type:
cd /Users/theta/Library
Press Return.
Type: mv Preferences Preferences_old
Press Return.
Type: mv Caches Caches_old
Press Return.
Type: reboot
Press Return.
If you can now successfully start and log in...
Corrupt plist, 3rd party startup item, corrupt directory, are all suspects, especially after a "crash" or hard freeze the directory and filesystem could be left in an unusable state. I always first reboot into single user mode to run fsck along with applejack. Did Disk utility find errors and repair them or not?

IMac G5 PowerPC boots up and freezes at light-blue screen

PowerPC G5 20" iMac, 2.0GHz, +260 GB harddrive, 2 GB of DDR SDRAM
Leopard OS 10.5.6
Computer starts up and freezes at light-blue screen. Mouse still moves, bu no keyboard commands work. Only holding the power button will shut down the computer.
Tried the following:
- Able to boot into Safe-mode only.
- Ran OS Disk Utility to repair permissions and also MacTuneUp 3.6.0, and no change
- Tried changing start-up to boot from OS 10.5.6 DVD and still freezes with light-blue screen. Safe-mode allowed me to run Disk Utility but no difference.
- If I leave the frozen light-blue screen, eventually the iMac power-saving mode darkens the screen, until I move the mouse (then light-blue again and still frozen).
- I left my iPhone connected to the iMac, and when starting up the computer the iPhone started charging. When the light blue screen froze the iPhone stopped charging.
- tried starting computer with Options + Command keys
- tried + Options-Command-P-R untill you hear two beeps: Reset NVRAM (restart 3x)
- tried Resetting the SMU > Unplug all cables from the computer, including the power cord. > Wait 10 seconds.> Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer. > Let go of the power button. > Press the power button once more to start up your iMac.
Questions:
> When booting from OS 10.5.6 DVD, Should I run Time Machine Restore system from Backup?
> I can work fine in Safe-mode all day, but limited resources. Is this a software or hardware issue?

Based on what you have you tried I would guess it is hardware problem.
First iMac's without camera and with GeForce FX 5200 graphics card are known of having capacitor failures which can cause the machine either to become unstable in different situations or fail to boot up at all. I have repaired many of them and changing capacitors brought completedly dead iMac (no power, no nothing) up to life so capacitors mean a lot.
Second and third it's mainly the graphics card which fails, causing the machine to fail to boot, become unstable or boot with artifact patterns in picture.
There has also been power supply issues and Apple did issue a recall back then, I think you can still find article about it and check if your machine has serial number which fits to that recall problem. This way you could check if you should suspect power supply going bad.
Capacitor problem is usually easy to identify (open up the case and look if those can-like things are bulging or swollen) and quite easy to repair if you have bit experience in computers and soldering, iFixit.com provides great disassembly instructions. Graphics card problem is harder to identify because in that case it is the solder which breaks under the graphic chip so you cannot actually see the defect. It is also harder to repair atleast if you want the machine to work long time after that repair. Basically you would need to heat the GPU enough to reflow solder connections.
Because the machine can boot into safe mode I'm suspecting that you have some of these issues I described, safe mode does not utilize hardware at full power and disable full graphics acceleration for example.

Mac Freezes on Blue Screen After Installing Updates! Help!

hi
Have just done the updates that were available for my wifes mac mini. All went well and it said restart to complete. I did this but when it restarted it would not get past the blue screen, the mouse cursor is there and moving but thats all.
Now my problm is i haven't got a clue about mac's, the wife is away and don't want to tell her that i've managed to trash her Mac as she has got quite a bit on there. If it was windows it would be fine as am happy with that but it isn't and i am stuck!!!!!(read dead if i can't sort it out before she gets back!!)
Now what i want to know is how can i basically get it back to where it was before installing the updtaes or can i get back to a state of working without deleting anything progs installed etc? With windows you can use there system restore after booting in safe mode. Is there a way i can do it with the mac or something along those lines.
i know this is probably a pain post but i am stuck
Cheers in advance for any help

The only way to get back to a state before the updates is if a backup was made.
As for booting in safe mode, you can try holding the shift key.
If that works, it says that some attached peripheral needs an updated driver. Remove all third party peripherals, and see if it boots.
If It doesn't boot, it is likely the directory is damaged, or the hard drive is very full, or the hard drive might be dying. You can also try zapping the PRAM:
http://docs.info.apple.com/article.html?artnum=2238
Unfortunately there is no way to tell the difference between the above possibilities, and if you use a directory repair utility on a dying hard drive, it may speed its death. How valuable is her data to her, and is it backed up anywhere?

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

On startup Mac Pro I get a blue screen and a cursor on the upper left. The mouse cursor shows up independently. Is it likely a video card failure?

I managed to boot the computer and get the desktop to show. I now have a "repaired" computer. There are several problems that have cropped up. One is that I can only start up now in Safe Boot mode. Is there a way to turn it off? Also, I do not have a sound list, so I can't access anything requiring audio. Google Chrome only shows up as a white screen. Pictures that loaded before don't load in browsers, etc. Any suggestions? I figure I should reinstall Mac OS Lion for starts, maybe even do a mirror backup and reformat the drive. I think this drive has turned into scrambled eggs...what a headache!

HELP! OS X won't boot - Blue Screen at startup... No mouse, nothing...

I have a PowerMac G4 MDD running OSX 10.4.8 (or 9)... About a month ago, it suffered a kernel panic, and upon restarting, it wouldn't load OS X. Now whenever I start the computer, it displays the white screen with the Apple logo and the spinning gear, then it switches to a solid blue screen and stays there. There is no mouse on the screen and the keyboard is unresponsive.
The computer will boot in safe mode. I have tried removing login items in the account preferences and third party items from the StartupItems folders. But still, I get the blue screen.
I've tried resetting the PRAM. I booted from the install disc and repaired the startup disk. It said no repairs were necessary. I've repaired permissions on the disk as well. I also booted from the Hardware Test disc, but still, nothing.
Yesterday I did an Archive and Install from my Tiger install disc, hoping that this would fix things, but it didn't. As a last resort, I'm considering wiping the hard drive and doing a fresh install of OS X.
Does anyone have any advice? Has this happened to you too? Does this sound like a hardware or software problem?
PowerMac G4 MDD Mac OS X (10.4.8)

Do you have a firewire external drive, or other bootable backup? Try booting from another drive & see if the problem persists. Run Disk Warrior while booted from its CD, or from an alternate drive. I don't think it will help, though, because Archive & Install should create a new directory. If the problem persists when booting from an alternate system, you most likely have a hardware problem. You could install a fresh copy of OS X on your alternate drive to make sure (but not if it's your only backup!).

Installation-stuck at blue screen requesting removal of mouse batteries....

Hi - Thanks for you help in advance....
Trouble installing Leopard - here is the sequence I am stuck in - I have tried 5 times to install...
1. Turn on computer with disk in - gray screen with apple comes up.
2. Blue screen appears for a while.
3. Gray screen requesting removal of batteries from mouse comes up. I remove batteries and flick switch. The arrow prompting me to continue never becomes clickable.
4. Screen turns black and cd still runs.
I have tried looking at support articles....thank you very much for any ideas!
Paul

Get (or borrow) a USB mouse and keyboard; very useful for problems like this.

Blue screen, mouse battery image

Bought a white Macbook, just over a year old. Replaced the hard drive to a compatible 320gb WD Scorpio Blue and 4GB Ram.
Tried to install Leopard on it. Usually tone, Apple sign, then spinning circle....then it pauses a bit to a blue screen with then a picture with a grey background, and an image in white of two mice 1 and 2 asking me to replace the batteries. Firstly this is a laptop and I dont have an external mouse for it.
Either way the cursor doesnt move and the keyboard appeards not to work either.
Any ideas?

What disc are you using to install Leopard on the machine? Did the computer come with any discs?
My computer is just over a year old and came with Leopard installed.

HT1436 My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?

My Power Mac G5 will not fully boot without safe mode, it only comes to a blue screen where my cursor duplicates in to 2, (one is frozen, one can move by moving the mouse). What is my problem, and how do I fix it?

Great clue Lukas...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...
