PowerPC :: IBook G4 Won't Boot Past Apple Screen & No CD Boot

Jun 11, 2007

I have an iBook G4 1.07 GHz 30 gb 256 RAM with Panther. It was working fine until my HD got close to being full. Now I can't get it to boot past the Apple screen. It will either freeze there, or move on to the blue screen and freeze before the progress bar enters. I want to re-install Panther but I can't get any CD to boot during startup by holding "C", including the Panther OS CD, the Hardware Test CD, or the Tech Tool CD. I am able to boot to single user mode, where I type fsck -fy, and I recieve no errors with the hardware. I had this issue beore and my HD had to be replaced by Apple.

PowerPC :: IBook Won't Boot Past Gray Screen

Dec 30, 2010

I'm trying to resurrect an iBook (translucent white case, 14.1 LCD) that was long neglected, so not sure on its past service history. The following do NOT work: - won't boot up past the gray screen with Apple logo and spinning gear icon (just hangs) - same problem if I try to boot from install DVD ("c" or using "option" then selecting DVD) - same problem with safe boot with "shift" - reset PRAM It will connect via firewire target disk mode to another computer, and I used that to completely wipe the disk and do a clean install of 10.5. When I tried booting into single-user mode (cmd-s), it fills about 2/3 of the screen with normal-looking messages, but then hangs after this (no keyboard response): Got boot device = IOService... [various other stuff] BSD root: disk0s6, major 14, minor 5 I'm out of ideas. Any suggestions? The machine is old enough that it's probably not worth the diagnostic fee of the local Apple shop. Since I can't get it to boot, I can't even run TechTools.

PowerPC :: G4 Won't Boot Past Gray Screen With Apple

May 1, 2009

I recently required a Power Mac G4, and it was working fine, albeit a bit slow but I just assume that was because there's too many files on it, but that's another story. I shut it down before I left work, when I came back in the morning it was just the grey screen with the apple. I reset it, still no response. I reset the PRAM, nothing. I tried to boot in Single user mode, nothing. I tried to boot in verbose mode, nothing. I force ejected the CD and put in an OSX disk one from my laptop, asked it to force read by restarting and pressing "C" and still nothing. I am not sure if a cable inside has been jarred lose.

Software :: Ibook G4 Not Boot Past White Screen

Jun 24, 2009

I've searched this problem on google for the past hour or so and have had no luck whatsoever. I have an Ibook G4 14" and I think it's like 1.2 CPU. A while back the Ibook stopped working and left me with a grey screen and finder icon with flash quiestion mark. I searched the net for a solution for that and what came back was that I had a dead harddrive. Okay fair enough, I've just replaced the drive with the working one from my Mac Mini, i repeat the WORKING drive, I know it works. So I start up the Ibook and hear the chimes, the screen flashes black white black and then stays on white. I have reset the PRAM and eject disk works but no other key commands, I cannot boot from installer 10.4 cd (a new one I bought, not the bundled one), I can't go into target mode as I have no firewire and leaving it alone for a while doesn't help.

Software :: G4 IBook Won't Boot Past Blue Screen

Oct 4, 2009

I am trying to reformat an iBook for a friend. Everything was running, but, there was no chime on boot. I logged into the machine, and was checking files and folders when it locked up. It actyally locked up while trying to run Microsoft Word. It now boots to a grey screen the the little "spinning" thing, and then, instead of going to the login screen, it just turns blue. It will NOT boot into Safe Mode, it will NOT boot to the iBook Install CD, I just get the same blue screen using both methods. I used Command-Option-P-R without success. I booted to Open Firmware and typed reset-nvram without success. I don't know what else to try. I am copying her files right now by booting into Target Disk mode, but, once I get that done, I still won't be able to boot the install disc to get the system wiped and reinstalled. What else can I do to correct this?

PowerPC :: Installed 3rd Party RAM Then IBook G3 Won't Boot Past Flashing Folder?

Sep 30, 2007

I have an iBook G3 Clamshell 466MHz with 192mb RAM and 10GB HD. I recently updated the OS from 9.2.2 to Panther on a single partition. The upgrade went flawlessly.Then I purchased a 512mb RAM module from a 3rd Party Vendor and after fitting it discovered the iBook no longer boots past the flashing folder/?.

I removed the new ram and replaced the 128mb module but haven't been able to boot past this flashing folder/? icon. I've zapped the PRAM, reset Open Firmware, disconnected the Keyboard then booted, reset the PMU (need to do this each boot or I see black screen only) and tried to boot from the Panther Disc #1 holding the 'C' key. I also tried TDM with my Intel Mac Core 2 Duo but couldn't boot past the flashing folder/? icon.

IMac :: Won't Boot Past Apple Screen

Mar 5, 2010

I have one of the old blue PowerMac G3 computers, and I kept getting a kernel panic, so I reset the RAM and now when I start up the computer, it stops at the apple screen without even spinning. I've tried booting it in single user mode, and for some reason it doesn't make a difference what keys I hit while turning on the computer. It still boots to the apple screen.

Power Mac G5 :: Won't Boot Past Apple Logo Screen?

Nov 23, 2007

I'm trying to repair a Powermac G5 (dual 2.0, the first model I believe, with a new Radeon 9800 graphics card) that won't boot and I'm having some problems that I can't seem to diagnose.

The machine will boot to the openfirmware prompt or target disc mode and will show the 'OS not found' icon if left to boot from the HD (which has been wiped). If I try to boot from either the included restore disc or a retail 10.4 DVD I've tried it will show the boot screen with the Apple logo on it but no spinning status indicator underneath. It just freezes on that screen. Once it showed the status indicator but it just continued to spin for about 30 mins, at which point I gave up. Same issue if I try to boot the hardware test (except it freezes on the hardware test loading icon rather than the Apple icon). The superdrive appears to work as it is accessible in target disc mode.

I've reset the SMU and reset the PRAM via the keyboard shortcut. The one thing that leads me to think it's a firmware fault is that when I run the 'reset-nvram' command it gives an OK, but when I then run 'reset-all' it freezes rather than rebooting. Any ideas anyone?

Software :: G4 Refuses To Boot Past Apple Screen

Jan 9, 2009

I have just finished moving my G4 Sawtooth from one house to another. I shut down my machine properly at the one house carefully moved everything over and re-attached the peripherals. Fired up the machine and was greeted promptly with the Apple boot screen and spinning thingy. Then it spun and spun and continued to spin some more. After about 10-15 minutes my desktop backgrounds appeared on the dual monitors, but then sat there like that and no finder ever appeared. After waiting about another 5 minutes, I shut off the machine by holding down the power button. I waited about 10 seconds and powered it on again. Same thing, but this time it just sits at the grey Apple boot screen with the thingy spinning forever. Then I noticed something unusual.

I could hear one, or both of the internal hard drives park the heads and spin down like it was going to sleep. I hadn't noticed that before, but presume it was doing it all along. Meanwhile the computer kept spinning away on the boot screen. I thought, great my drive has crashed and burned. So I removed it and attempted to mount it on my G5 using an external ATA-USB adapter. It mounted without a problem and I was able to see and copy all of the files. So then, I took a spare drive I had with a valid bootable OSX Leopard install and put it into the G4. Fired it up and lo and behold, the same problem. The drive spins up, the machine shows the apple boot screen and keeps spinning the thingy, then after a bit of time the drive parks the head and spins back down. I'm stumped and would like some assistance in resolving this problem. Any suggestions? Oh, and yes, I've tried reseating all cards and memory and disconnected all peripherals.

Intel Mac :: Boot Partition Error Message - Mid 2010 I7 Will Not Boot Past The Apple Logo

Apr 8, 2012

My mid 2010 iMac i7 will not boot past the apple logo? I'm running 10.7.3. I have tried restoring from TM backup from recovery mode (worked the last time this happened) however upon completion it returns to the recovery screen? I made a disk of Lion when I downloaded the first time (followed same instructions sourced from numerous websites) which does not seem to work when i set to start up from this disk, just gets to the grey screen and flicks between the apple logo, a folder icon with a question mark and the circle with line through? Now I can't eject the disk either, a message appears that system can't eject and to make sure all applications are closed? Not sure how to go about closing these applications without being able to start the system? When I tried booting from the Macintosh HD I got a message that the boot cache partition was faulty? I have ran disk permissions etc all ok.

PowerPC :: G4 Silverdoor Does Not Get Past Gray Boot Screen

Feb 6, 2008

At the tech dept we have this G4 that refuses to boot past the grey screen with the rotating wheel. The logic board has been replaced, we've removed all sticks of RAM save 1x512, we've tried a known working optical drive, replaced ribbon cables (optical cable was frayed on one end) No dice. Option booting works, but once we select the DVD we can't boot from an install PPC CD either, it just gets stuck at the grey screen. We also have a tech HD inside that the computer does not boot from either.

PowerPC :: G4 15" Won't Boot Past Gray Screen

Jul 17, 2010

I was given a PowerBook G4 15" today. I need to fix it, but I can't find out what exactly is wrong. I've used MROOGLE and I can't find any problem quite like what I'm experiencing. In my case, the laptop will turn on, make the chime, and stay stuck on a white/grey screen. No apple, no spinning gear, no nothing. Just a blank white/grey screen. However, when I insert the Leopard DVD and hold down "C" the apple appears as well as the little spinning gear. That goes on for a few minutes. BUT, after those few minutes are up the small gear still spins, but the Apple logo is replaced with a prohibitory sign (like what you would see on a non-smoking or no parking sign) and it sticks there and sometime says that I need to re-start my computer. The same happens with the Tiger disk. Also, when I place the Leopard or Tiger disk in the SuperDrive and hold down "option" so that I can boot OS X from the DVD, I click the little continue arrow and nothing happens. I've reset everything there is to be reset, and I've opened up the computer and re-seated everything that could possibly be re-seated. RAM, HDD, all connector cables, etc. There isn't any visible physical damage inside of the computer either.

The most recent thing I've tried was to boot off of a PPC-specific Ubuntu disk. It does some stuff and lets me run the kernel, but after that the computer gets stuck on a black screen and does nothing at all. I'd really appreciate it if you all could offer some advice as to what may be wrong. All suggestions and ideas are welcome too.

MacBook :: Won't Boot Past Gray Screen With Apple Logo And Then Shuts Off

May 29, 2012

This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

Power Mac G5 :: MacBook Pro - Tiger Won't Boot Past Grey Apple Screen W/ Spinning Gear

Nov 12, 2007

I have a 1.83 Ghz MBP with 512 mb of RAM (lame I know). The other day someone was using my computer to burn a CD on iTunes when all of my programs began failing. On instinct I rebooted my computer to solve the problem. Alas, now I cant boot past the grey apple screen, and the gear is spinning away. Saddest part of the story is that I had time set aside to back up my computer the day after this happened . Anyway what is the best thing to do from here? I haven't made any moves to fix it yet really, so what is the best thing that I can do to try and get my files back?

PowerPC :: IBook Goes To Grey Screen - Won't Boot / How To Fix It

Sep 15, 2006

I have seen this talked about a fair bit, but i thought i'd start my own thread because it seems slightly different.

To start, when the computer was last running, the (what sounded like fan) started making a terrible noise, then stopped, and the computer turned off.

After that, when booting, it just goes to a grey/blue screen and sits there.

I have an iBook G4, 1064mhz, 256/30.

I dont know what model that makes it, but from the Mac website, I have tried to reset the PRAM to no avail. All of the methods listed do not seem to do anything on my ibook.

I tried using this link to reset the [URL]

I dont know which one is for my model, but i see no reset button under the keyboard, or on the case. There is a little tiny hole on the case beside the LCD???

I have tried the shift-ctrl-opt-power but it doesnt do anything.

As well, i did hold down the "option" button when booting, and it brings me to a screen which shows an image of a hard drive with a green "x"

I dont know if the green means good or the X means bad..

I have read that resetting PRAM and/or changing the resolution seem to help the problem, but I do not know how to do either.

PowerPC :: IBook G4 Won't Boot Beyond Blue Screen?

Dec 13, 2007

After installing an app ('Detour') I was asked to (or it was suggested that I should) restart my computer. I did so, and now my 1.33GHz iBook G4 turns on - but it will not go any further than a blank blue screen (after the initial grey screen that appears.) Thankfully, all my data is on an external drive. I keep my music and footage which I have shot on there amongst other things. I also have a backup on my external via Time Machine of all my data which I keep on the iBook drive, so nothing should be lost.

MacBook :: Won't Boot Past Grey Apple Logo

Apr 22, 2012

My mother's unibody white MacBook will not get past the grey apple and spinning gear when you first boot up the computer. This was after she opened a link in an email from a friend who had her email compromised. Now I'm getting spam emails with the same link from my mother's hacked email, and her computer won't even get to the login screen. I took it to the genius bar only to be told it was likely HD failure, but the windows partition works without a hitch! What could this be? A trojan? Is there any way to retrieve data (really just pictures) before I attempt to reinstall OS X?

I'm a film composer in the middle of a deadline, and my G5 crashes won't boot again, only get grey screen with Apple and spinning logo.Boot from Applecare disk, run tech tool, hardware fine, disk is corrupted. Catalog B-tree stuff. Cannot re-build without destroying data.Of course I have a clone of my system drive and try to boot from that, but IT is corrupted too of course!Go to Apple Store (I have ProCare), then run diagnostics and find the same. Advice? Wipe the drive and start from scratch.I do just that. I own about 35 plug-in instruments for Logic 8, so it took two days. The same thing happens. Disk won't boot.

OS X :: Can't Get Past Loading Bar In Boot Screen

May 24, 2010

My mac was shutting down and it took sooo long (blue screen with the spinning loader). I never experienced this, cause normally the dock would vanish and my mac would shut down instantly. But this time it kept showing a blue shutdown screen, so I decided (after about 2 minutes) to hold the power button and force a shutdown. The next time I booted the mac it showed me the gray boot screen, with the spinning wheel and a gray loading bar, which I think is indicating a firmware update or something that has to do with my forced shutdown. But the bar gets to about 1/8 and then vanishes. The spinning wheel stays, but nothing else happens. It just hangs and keeps spinning forever.

OS X :: Macbook Won't Boot Up Past Blue Screen

May 16, 2009

I hardly ever turn off my Macbook unless i need to - I just close it and use it whenever i need to. I let the battery run dry as Apple suggests to do every now and again, and turned it on the next day. It started to boot and took a little longer to get past the grey apple logo and loading circle and then froze on the blue screen. I can control the mouse, but every few seconds it changes to a darker blue, cursor disappears but returns after a second or two. I've tried:

- Booting into safe mode (Same thing happens)
- Booting from CD and repairing permissions (Said everything was ok, same thing happens when I booted)
- Single user mode (used some commands from an Apple page and restarted)

I can however boot into windows perfectly fine, which leads me to suspect it's a corrupt log in item. I'd like to know for sure it's not a hardware problem so I don't have to take it into an Apple Store.

MacBook :: Why Can't Boot Past The Grey Screen With An SSD

Apr 1, 2012

My wife has a Macbook with an Intel Core 2 Duo processor (Macbook4,1).  I am trying to replace the original SATA hard disk (160 GB) with an SSD.  I have two SSDs here with me: 

1) Intel 320 series, 160 GB

2) Crucial M4, 128 GB 

In both cases, after replacing the hard disk with the SSD, I am unable to get the Macbook to get any further than the "Mac sound" and grey screen. 

In my first attempt, I cloned the original disk to the SSD on another computer, verified the data got on there OK, and installed the SSD into the Macbook.  In subsequent attempts, I just formatted the SSD to see if the Mac would recognize it at all. 

When the original hard disk is installed, and my Snow Leopard install DVD is in the DVD drive, during the boot, I can hold down the option key and get a boot choice of booting from the hard disk or the DVD.  With either SSD installed, when holding down the option key I get no choices at all, it just sits there (it does access the DVD for a few seconds but then nothing). 

I have another 160 GB "regular" hard disk here as well and when I install that I also get the choice to boot from the hard disk or the DVD (although booting from the hard disk does not work since it's a hard disk from a PC). 

combination of Macbook and SSD, installing into the hard drive bay?  I've seen many posts from people who have had success putting an SSD into their Macbook so I am assuiming it's possible. 

Some more information about the Macbook:

Boot ROM Version: MB41.00C1.B00

SMC Version: 1.31f1
