Power Mac :: G5 Stuck At Light Blue Screen - Will Not Even Boot In Safe Mode

Mar 22, 2012

I have a 2.0 GHz early 2005 Power Mac G5 (7,3) that won't get past the light blue screen at start-up. I've tried everything - reset the PRAM, Apple Hardware Check (on overnight loops, everything came back OK), fsck (all OK), repaired my HD and permissions on it, and then erased the drive using Target Disk Mode and another Mac, and attempted to reinstall OSX from the install disk that came with it (with OSX Tiger). I've tried switching out the RAM with no luck.

The only thing I haven't tried is a new video card (the installed one is an ATI Radeon 9600). Here's what it does: powers on with the usual chime, then moves on to the white Apple screen, the wheel spins, then it moves on to a darker blue screen, then it finally moves on to a lighter blue screen with an arrow, and it just stays there. It will boot into safe mode (pressing shift), but I can't even upgrade to Leopard in safe mode, much less figure out what's wrong.

MacBook :: Boot In Safe Mode - System Stuck At Blue Screen

Nov 30, 2010

I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?

OS X :: Freeze On Blue Screen / Can Only Start Up In Safe Mode

Sep 21, 2008

I woke up this morning and my iMac G5 (w/ Leopard) was frozen. I restarted it manually, but it would freeze on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM - any other ideas?

What can I do in Safe Mode that might fix my comp? I haven't recently installed any applications, and I have all "open at login" items turned off.

IMac :: Hang Up On Blue Screen - Only Boots In Safe Mode

Tried everything from archive and install (wouldn't read disk2 until the 9th try and ended up with 9 system folders). Then tried an Erase and Install. Still it refuses to boot. Get's hung up at the blue screen. Will only boot in safe mode. Now for the last few days even the startup chime is missing. Tried PRAM and NVRAM resets. no help. Won't boot from DiskWarrior boot disk either. Just hangs

Software :: Frozen On Blue Screen / Only Safe Mode Start Up

Dec 8, 2008

My iMac G5 froze. I restarted it manually, but it kept freezing on a blue screen without loading the OS. It can start up fine in safe mode, but that's it! I've tried repairing permissions and zapping the PRAM.
Finally I resorted to an Archive & Install. That didn't work so I did a clean install but that didn't help either. After having done everything under the sun to it to get it to work, it will still only start up in safe mode. I even tried starting up off each of my two external fire wire drives with no luck (it froze on the fire wire screen with both drives - a Maxtor and a Western Digital). I am thinking that something on the mother board has died so that normal booting is prevented but safe mode booting is allowed.

Software :: IMac G5 Stopped At Blue Screen (Safe Mode)

Sep 6, 2009

When I turned my iMac on this morning (iMac G5 PPC 10.5.8) it went through all of the "normal" steps (gong, grey screen, apple logo, progress wheel, blue screen) and stopped at the blue screen. Thinking it was just a fluke, I shut the machine down and restarted, only to have it stop at the blue screen again. After disconnecting everything going into the iMac except the keyboard and mouse, I attempted to boot into safe mode but it stopped at the blue screen again.

Next, I flashed the PRAM (big gong, single quieter gong) and afterward it came to the blue screen. I reattached my external drive and selected to boot from a 2-day old backup. Using the backup I was able to log into both my regular account and my "test" account (without login items). I still cannot login (except to my external drive backup).

Power Mac G5 :: Startup Only In Safe Boot Mode

Oct 11, 2007

We have an older model G5 Dual (no Intel Core) at the office that we tried to install CS3 on. I told them that first we would need to upgrade from 10.3.8 to 10.4.10, which they did, and then installed CS3. But they did it without running the disk utility repair permissions after the OS software installation, as I have routinely done with my Mac Mini at home, after the horror I experienced with the 10.4.9 upgrade. For a couple of days, the computer ran fine, but I noticed an increase in the fan spinning up yesterday afternoon, then quirky keyboard things -- like I'd select an item with point and click, and it would highlight everything else near it, I'd go to quit an application and it would ask if I wanted to quit all applications.

After backing up my current InDesign work files on a flash drive (but not the whole darn art folder), I rebooted and it came up in Safe Boot mode 6 times without holding any key down. Attempts to boot from disk have failed, even with holding down the "C" key. It's also not allowing us to type out full passwords at the log-in screen... you start typing and after you hit four digits, it clears, then only allows two digits. How we can:
1.) Force boot from disk, and,
2.) Hopefully fix with disk utility whatever wonkiness is occurring?

Mac Mini :: Slow Bootup With Blue Screen - Able To Enter Password In Safe Mode

Nov 28, 2009

I've been using my Intel Mac-Mini without a hitch for three years now. Previously it had been plugged into a Samsung 32" LCD TV, but I've just swapped it over for a 1080p Panasonic 37".

Now when I turn on the mac it takes a long time to boot up and then eventually settles on a blue screen. The mouse pointer is visible but nothing else. I've tried using a dvi to vga adaptor and an HDMI to vga cable and the same thing happens.I tried a 15" Samsung monitor and the same thing happens.

If I boot in 'safe' mode it allows me to type in my password but when I try to log in it fades to blue and then returns to the log in page.

OS X :: Won't Boot In Safe Mood / Only Boots To A Blue Screen

Aug 24, 2010

I just go a new Macbook Pro 13' from my school (my school made it mandatory to get a mac this year) and I was installing some of my applications. Then I got the "You need to restart your computer" message. I restarted, and all i got was a blue screen with my pointer. Then after a while it says the same restart message. Also I have tried booting from the Snow Leopard Disk, but I get the same message before the actual SL installer comes up. I have been able to get the Macbook to boot in safe mode and I repaired permissions and the disk, however that does not seem to help. I have also reset the PRAM and that did nothing. I am running out of ideas... how can I fix this? I am using 10.6.4.

MacBook Pro :: Starts With Black Screen Only - Same When Boot In Safe Mode

Dec 6, 2014

My MacBook is making the startup sound but goes straight to a black/dark grey screen. In other words you can see the screen switching on but it's blank. It's in charge mode, has no other external peripherals attached and it's updated to most recent OSX Yosemite.

I only purchased it in May of this year (refurbished). I have tried booting in to safe mode but again the screen remains the same.

OS X :: Stuck On Blue Screen And Gray Gear Spinning On Boot Up?

Mar 30, 2009

Everything was fine until this morning when i came into work, started up my Macbook as usual from sleep mode. was able to use OS X for a little while, had to leave to go onsite so i locked my screen (i use sizzle keys and made Command + L to lock my screen to the log on prompt). as soon as the cube spins to the logon screen, BOOM, all i see is the solid light blue screen just sit there. i walk away and 5 minutes later, it's still on there, can't recover or go back to my desktop, so i force shut down (hit the power button, and attempt to reboot the OS X. then thats when it all gets bad. Everytime i boot into OS X it just sits there with the blue screen and flickers back and forth with the gray gear wheel spinning and so forth.

Ok, so next check, i go to boot into my Boot Camp partition into Vista. no problems, was able to boot in my boot camp partition without any problems (im typing this in boot camp at this moment.)

So far i've been able to boot into my Boot Camp and the OS X Restore Disc without any problems.

I booted into the OS X boot disc, and ran Disk Utility, ran the perrmissions check and the disk check and both fixed problems aparently on my OS X partition. went to boot back into OS X, blue screen.

So now i do the PRAM and NVRAM reset doing Command+Option+P+R and again booted into OS X. blue screen.

Booted into Safe Mode (Safe Boot) took awhile, but again. stuck at blue screen and if i press any keys or move the mouse, the grey gear spins for like 10 seconds and just goes back to the blue screen. and the process goes over and over again.

(later on this afternoon) I even ran FSCK to check the volume for problems. "it appears to be OK"

The good thing atleast in this situation is that i can access my OS X partition in Vista (via MacDrive) without any problems, so if having to reload my previous Time Machine backup (which stupid me forgot to back up my system over 60 days ago ) or having to just Archive my OS X and reinstall it, that will have to be my final choice. But i don't REALLY want to have to do this all over again if at all possiable.

OS X :: Power Mac G5 Not Boot - Stuck On Logo Screen

I'm in way over my head after promising to fix my father in laws power mac g5. When I press the power button everything seem normal. You hear the apple sound but after a short while the fans speed up the screen turns grey with a folder icon and a flashing question mark and then the apple logo appears. I have never been past this stage. I have paired the memory installed correctly and I have tried every memory combination possible. I have reset the Pmu and I have reset the pram. I also tried to remove the battery but that didn't help either. I also tried to boot from a system disc but nothing I hear the disc spinning but nothing happens.

IMac :: One Stuck Pixel In Light Blue Colour?

Aug 19, 2009

Yesterday I received my first brand new iMac 24". After a few hours I notice that it has one stuck pixel (in light blue colour, so I think it's not dead).I read Apple policy about 7+ stuck/dead pixels

My question is what can I do? If I want to return it, I will have to wait 1-2 weeks and then again play lottery with panel and HW (also that option would cost me additional EUR - I received 10% discount as a student and this is the only store where I have discount (and only for one computer per year I have 10% discount) - If they won't want to switch it, I would get back 1300EUR, while new one is 1500EUR in other stores).

Second option is to try fix that myself. I read tutorial on the net and the author claims 90% success with stuck pixels (with "massaging" pixel). The only problem here is the glass, I know how to remove it, but probably there would be a lot of new dust after doing that between panel and glass - and the imac is only one day old . I try with softwer and "epileptic" videos unstuck that pixel but it didn't worke (I try this for one hour).And the third option to simply forget that exists (is there a bigger chance to get another stuck pixel if I already have one???).

MacBook :: It Won't Boot After Trying To Repair With Disk Utility, Cannot Boot In Safe Mode

Jun 11, 2012

I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.  

I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc". 

I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.

OS X :: Can't Boot In Safe Mode?

May 17, 2010

I have a 08 MacBook pro (not unibody) and it is now not booting up. I recently installed a Hitachi 500gb hard drive on the computer and restored through time machine and it worked fine for about 2 weeks and now wont boot and I'm wondering if its probably the hard drive. When I click power the light on the front of the computer will come on and it will sound like it is about to boot then a clicking noise seems to come from the computer and it instantly shuts off. I have gotten it to turn on a couple times since it happened by slamming the comp on the bed then for some reason it will work but as soon as I shut it, it wont turnback on. Any ideas?

Oh and PS the screen never comes on and can't boot in safe mode.

IMac PPC :: It Will Not Boot Out Of Safe Boot Mode

Apr 22, 2012

I have a Imac PPC with a 2Ghz processor and 1GB of Ram.  I am running leopard 10.5.8.  Recently i woke the PC from sleep mode to find a blue screen with only the cursor working.  Using the internet, I determined how to get the PC booted in safe mode.  I have used all the disk utilities at my disposal along with onyx and cocktail to try and fix what I believe is a startup problem. I hae booted the PC in single user mode and tried the fskc codes, which i believe is just the same as the disk utility. Based on my computer all permissions are correct and there is nothing wrong with the HD.  The PC still will not boot normally.  I have even done an archive and re-install of Leopard.

MacBook Pro :: What Can I Do In Safe Mode To Fix Boot

Jul 5, 2012

MY MBP is giving me the "NOT" sign on start-up. This comes after initially displaying the Apple logo.This MBP had a new logic board installed by Apple just two weeks ago -- and I know I can take it back but I'd like to fix this myself. I put in a different hard drive after getting the MBP back. It has worked fine for several days. Don't know if these points are relevant, but:

1. First thing I noticed today is that neither of the USB ports would read a flash drive. The port would, however, work mouse and keyboard.

2. The initial non-boot episode took place when I had external hard drives daisy-chained in via Firewire. But, again, this had worked previously, as recent as this morning.This may be significant:

3. The last tasks performed on the MBP were -- for the first time -- to edit video in FCE, make DVD in iDVD, burn IMG file.

4.I have connect this MBP as a target FW drive to another MBP and run "disk verify" and "disk repair" in Disk Utility. It says the drive and permissions are okay.

5. I have booted to a copy of Disk Warrior (latest version, version 4, I believe) and rebuilt directories and files along with verify/repair permissions (everything DW will do). And when re-starting, it still won't boot.

6. When I boot off Snow Leopard DVD and run Disk Utility"verify disk" says "the volume appears to be ok.when I "repair disk" it reports "Volume repair complete." and "Updating boot partitions for the volume as required."

7. I'm able to boot in SAFE MODE, but when I try to restart in normal mode, it won't boot (so nothing was automatically fixed)What can I do in safe mode to address my problem?

OS X :: Unable To Boot Into Safe Mode Or Use Install DVD

May 11, 2010

I am using a Late 2009 Mac Mini. This afternoon I did a software update, it was 4 programs that were updated. I didn't take a look at what was updated, which was a mistake, I know. But anyways, they installed fine, and the Mac rebooted, it got to just before the user select/login screen and hanged there. I was able to move the mouse around, but nothing else, and after a long period of time, I powered off my Mac, and now it is hanging at the Apple logo.

I tried booting into Safe Mode, and the grey progress bar would appear but and get half way through and then disappear. Next I tried inserting the Install DVD, hold down C while it was booting up but that wouldn't do anything.
