PowerPC :: Pre ISight G5 IMac Never Gets Past White Apple Screen
Aug 30, 2006
At work, we have a 17" G5 iMac from back before the iSight was put in. We're an Apple shop, so we have the new iMac actually on the floor for people to try out. The old G5 this thread is addressing is up on a shelf, but we want to turn it on as a display model. We plug a temporary mouse and keyboard into it, but the machine never gets past the white Apple screen with the "I'm thinking" animation. After a minute or two, the fan turns on full blast, but the white screen remains without any signs of moving on. What is our problem?
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.
When I turn on my computer, the wheel keeps spinning and stops on the grey apple screen. If I leave it there for a few minutes, the fan gets really loud.
I tried pressing Apple, Option, P, R, but it only chimes once.
I also tried holding down shift and restarting.
And I tried holding down option and restarting.
I even tried to take out the memory and put it back in.
Nothing is working.
I have the startup disks, but I don't know how to put them in the cd drive.
Since the computer won't boot up, I can't open the tray.
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.
My mother's iMac G5 began this just two days ago. It turns on fine, but once is reaches the apple logo with the spinning wheel, the screen begins to exhibit what is shown in the pictures below. It first started when I opened an .AVI I received in an email from my uncle. When the file opened, the whole screen(within about 2 seconds) had discoloration and macro blocking spread from the center of the screen outward. After this I rebooted, tried again, and when I opened the file, it did the same thing. Now I can not even reach the log in screen. And after the screen has been in this state for a while, it may go blank and the fans run at full blast. I've opened the same file on a PowerMac G5 and a MacBook Pro with no problems.
I've got this little problem with my 2months old iMac i5 since this morning. Yesterday everything was fine, I Watched a movie and updated some software, nothing illigal or damaging. Today I tried to boot my iMac, It showed the apple loading screen, with some kind of loading bar under it. I thought he just had to do that because of the update, so I decided to make breakfast and come back to check on it. When I came back, the bar was gone, but he was still loading! (15 minutes later). So I decided to reboot. still the same problem. I decided to boot from cd to see if this works, to select the startup drive. First I tried to fix the hard drive, but it is unable to fix it. I don't care to format my mac, but would like to know if there are other options to try first.
I have a Powerbook G4 with me and it doesn't boot up. I am suspecting it is hard disk/ software error that is stopping it from booting up. Here is what I see when I try to power it up: White screen, Apple logo with the round circle with rainbow color. Do you guys think that is is a software error that is stopping it from booting up? The last thing I did was to install Windows Messenger for Mac! I am thinking of trying to do a re-install using the disc that comes with my Powerbook purchase but I am at a lost of what to do. Can anyone please share with me the steps that I need to take? I've got a 'new' hard disk already, please advise on how can I rebuild my Powerbook!
I just moved back up to Jacksonville with my friend and now his iBook G4 is not booting. It goes to the white Apple screen and spins for about twice as long as normal, and then goes to a black screen with just a type-cursor in the top left hand corner which erases any text submitted. Now, from there I went ahead and booted from the Tiger Install disk and ran permission repair and also disk repair, without any glitches. Also, we then booted again and ran a hardware diagnostic and it turned up absolutely no problems with the computer. Any ideas? Luckily, he's still under his first year of AppleCare (and he's about to purchase an extension since you can now get it in Florida legally) and he should be covered.
It will turn on and go to the white screen with the gray apple but even after several hours it wont do anything. I tried holding down C since my copy of leopard is stuck inside and it does the same thing.
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.
I just acquired a G4 MDD Power Mac. Dual 1 Ghz processors.I pulled the HD out of my older g4, connected it, and powered the machine up. The HD has OSX 10.5 and works fine in the older G4.
The first thing I notice is that the Small fan (in the door) is spinning, but the Large fan under the Power Supply is NOT. The red light on the Motherboard is on.
What happens is that all I get is a white screen, with the Apple Logo, and the spinning circle. it never acceses the hard drive and boots into 10.5 What does this point to? I hope the Dual processors are not the problem here. But that large fan not spinning worries me.
When I woke up this morning, I went on my macbook (which had been running overnight) and everything was running sluggish. I'd switch between programs and it would hang there for a couple seconds. So after closing all the software and it still doing that, I decided to restart. It wouldn't shut down, and eventually I had to force a hard shut down. When I turn it back on now, it won't go past the white screen. Nothing I've done will make it go anywhere. Holding down option only makes a cursor appear. I tried a tip I read about holding the power button down until the light flashes, and that hasn't helped either.
I've plugged the drive into my XP machine, and it doesn't show up in explorer, but does show up in disk utility. I installed the program TransMac that is supposed to let you access Mac formatted drives, and while the drive shows up in there, when I try to get to it, it says Error reading Mac Disk. So basically, I'm pretty sure the drive is failing. Now I need to know what I should use for recovery software. I've never had to recover a mac drive (I've been a mac convert for less than a year), and any file recovery software I have is for NTFS drives. So what software can I run on windows to recover a Mac formatted drive?
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.
Mac won't boot, starts with white apple screen and spinning wheel. Also has grey loading bar which disappears after loaded then stays at white apple screen.
Why is my Snow Leopard OSX 10.6.8 IMac screen all white when I turn it on? There is no spiral and no Apple logo and the desktop does not appear. The screen is just white.
Prior to this, we had a wind storm in our area with some power glitches today. After one of them, the dock items disappeared and just the wallpaper was there. The colored spinner began going around when I clicked on the mouse but nothing was happening. I unplugged it to try to reset it, but now the screen comes up all white, there's no apple logo that appears at start up and that's it. Now what should I do?
I am aware there are others threads of my problem however they date back years ago and after trying their solutions it still does not work.
After using Time Machine to restore my hard drive from a backup, I can't get past the white loading screen with apple logo after system restart during restore process. Ive gone into disk utility and repaired hard drive - it's fine. So I know this is a software glitch. I've also tried resetting SMC & PRAM (whatever those mean). No success and i cannot get past the white loading screen.
I'm running Mavericks (latest) on a late 2009 iMac
I have an iMac G5 iSight. When the power button is pressed there is no sound and a white light flashes, but nothing else happens. I tried the power reset method and replaced the power supply, but the same thing happens. The white light just keeps flashing.
So my 20" 2.4 Imac crashed on me twice tonight. A box popped up telling me to hold down the restart button for several seconds to restat. The second time I did this it just sits with a white screen and give three loud beeps over and over. Is there a fix for this? Is it my ram? I'm at a loss.
My step mom has an iMac. The first gen intel one and the other day out of nowhere there was a white screen with a folder on it and now when you go to start up the iMac the screen just stays white.. What would be the cause of this and what should I do to fix it .. thank you
I am having trouble with my macbook: It wont load past the Grey apple start up screen with the spining gears, iv done Zapp on the PRAM, iv run ""/sbin/fsck -fy"". And I am now starting in Verbose mode, but its taking AGES, it must be loading for an hour now, its showing "Neb-computer /System/library/coreservices/loginwindow.app/contenst/MacOS/loginwindow: Login window Application started (Over and over and over again). I don't have an install disk.
My computer wouldn't quit an application, so to shut it down I Pressed the power button until it turned off. I've tried To turn it on with cmd-v and it said <5% free audit space.I tried rebooting with cmd-s and it still hasn't worked.
I had to shut down my Mac Pro Server to move it & when I turn it back on it came back up to the log in screen. I went back into the server closet to marry an iPod Touch to it & the Mac Pro was off. So I pushed the power button to turn it back on & now it doesn't get past the Apple screen.
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?
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.
I am having a major problem with my MacBook Pro and it just wont boot past the apple loading screen at all I have tryed al lot of ways to fix this and it just wont work It does not go into safe mode, it does not boot from cd, the PRAM thing wont work, verbose mode or the comand + s mode wont work I tryed clean install but it wont boot from dvd, also it will not boot in any other way It was working perfectly last night and i just shut it down and it does not work know.
My friend was also trying to install Lion from his account but the .dmg for it did not open so we quit and that night i used it for my essay and finished and then i turned it off and next day in the morning it don't work
How to get my computer to turn on? I used it on Friday and had a normal shut down but when I went to turn it on yesterday, it gets the the gray screen with the apple and the loading bar and loads half way and then just stops and sits there until it eventually shuts itself off. I have tried turning it off and then back on and holding the D key but nothing happened.
