Power mac G4 450 won't boot past grey apple

I took trusty old Power Mac G4 450 (PCI graphics) apart for a week to paint the office. I put everything back together as before including a lot of old SCSI peripherals, but when I start it up, the fans run, i get the chimes, but it will not boot past the apple on the grey screen. I tried a safe boot, disconnecting everything but monitor & keyboard, & resetting the pram. The battery was replaced about 8 months ago. It had been freezing a lot before this, & I considered replacing it, but all I need it for is to run an old SCSI flat bed scanner that I'd like to hang on to. Any ideas?

Hi-
Will it boot to the OS X install disc?
If so, use Disk Utility to "Repair Disk" on the start up volume.

G4 won't boot past grey apple screen

Hi. I have been having the same issues with my G4 15". I'm frustrated. The whole thing started with stalling during applications. So I decided to reinstall my OS X 10.5. After reinstall, I copied my saved files from my "My Book" drive back to my hard drive. Stalling issues returned. I reinstalled again. still had some stalling issues, so I performed disk utilities. I repaired permissions. SMART status is verified. System still ran extremely slow. So, I followed directions on apple support for resetting the PRAM and NVRAM. After I did this, the computer won't boot past the grey apple screen. I have reset the PRAM and the NVRAM again. Still nothing. I rebooted up from OS install disk. I performed disk utilities repairing permissions and repairing HD. I did this for both my drive and the computers drive. I choose restart and again the grey apple screen. I have been trying to get this thing going for a week now. I'm near tears. Cornelius or anyone, can you help me? It says no errors are found, SMART is verified. But I can't get the computer to boot unless it is from the CD. Is the computer confused on where to boot from? Or is it shot? HELP ME PLEASE, before I play frisbee with my dear beloved mac!!!! It seems like this ALL started happening after I installed the update 10.5.8. I had ZERO problem prior to any software updates!!!

There have been report of some external drives/enclosures that do not work as a boot device. Not sure if the MyBook is in that category or not, just make sure that there is nothing else plugged into the Powerbook then try again.
Does the WD need its own power to be plugged into an AC power source? Try the other firewire port
I have one more question for ya... You were able to load OSX on this EHD using the OSX install disk in the Powerbook? And the installer saw the EHD with no problems?
If non of the above works try booting while holding down the x-key, this should force it to look for an OSX volume, not sure if it works the same on an EHD but worth a shot.

Powermac G4 (OS 10.4.11) won't boot past grey apple

1- My PowerMac G4 (running OS 10.4.11) won't boot past the grey screen with the apple. Any suggestions?

I found somewhere else how to hold down the mouse on starting, which opened the tray. I was able to startup with the disk, holding down the C and get to the Disk Utility window. Tried repairing the disk, but got this message:
Fist Aid failed:
Disk Utility stopped verifying "Macintosh HD" because the following error was encountered:
The underlying task reported failure on exit. <OK>
and in the info window it says,
"Verifying volume "Macintosh HD"
Checking HFS Plus volume.
Catalog file entry not found for extent
The volume needs to be repaired.
Volume check failed.
Error: The underlying task reported failure on exit (-9972)
1 volume checked
0 HFS volumes verified
1 volume failed verification
Sounds pretty ominous! Of course, the recommendation is that I backup everything , but how can I if I can't get to the desktop to back it up? (It hasn't had a lot of use for sometime, but is available as a film scanning station, and so that I can access scanned images on my iMac. I doubt that there is a whole lot on the drive that isn't backed up, but I would prefer to back it up for sure!)
Thank you again.

I need Help! Power Mac g5 computer won't load past grey screen.

Tonight my old power mac g5 computer (that I had for 8 years) has finally decided not to boot anymore. What happend was I was on my computer, and looking up something on spotlight until it froze over, (i am assuming its a kernal panic) It then crashed. I turned it off and tried to reboot it. At first, only the apple symbol appeared and no loading bar and then I turned it off again, but now I have a continuious loading bar. I've turned it off several times and rebooted but to no success (my cd drive is also broken) I fear I may have to get rid of it but I cant afford another tower right now..they're too expensive....What can I do?
Thank you, and I look forward to hearing from you.

OK, a number of things, sort of in order:
1. Does it boot from an install disc? You may need to hold the left button of a wired mouse down at boot to get the optical tray to open, or you can use open firmware to open and close the tray. (see below) Can you run Disk Utility from the install disk to check and/or repair your boot volume?
2. How about the PRAM battery? How new is it? If it is the original, you need to replace it for sure. If it if more than a couple of years old, it should be replaced preemptively as it is likely weak enough by now to have caused some mischief (more so if the machine has been off power and unplugged for any significant amount of time).
3. Have you tried a PRAM reset? (Hold down cmd-option-P-R key combination at boot until you hear the boot tone a second time).
4. Have you tried a PMU reset?
So what is happening is that something is getting hosed early on in the boot process. You might be able to see what is going on by doing a verbose boot (hold down cmd-V at startup until you get to the gray screen with Apple embossment) and hopefully getting the Unix terminal screen with its output detailing the boot process. Were I a betting man, I would have to guess a problem with the boot volume's directory structure. That's why I listed the booting from the install disc first. If it boots from the install disc, then most of the system is probably in good shape but there may be problems with the boot volume's directory.
Opening the disc tray using open firmware:
You boot into open firmware by holding down the cmd-option-O-F keys until you get the white open firmware terminal screen. You are not really using the hard disc or any really advanced capabilities of the system. Now, type the following command to open the optical drive tray:
eject cd <enter>
Repeat the command after inserting the install disc and the tray should close. Then enter the following command:
reset-all <enter>
and the machine should restart. You can either hold down the option key at boot to bring up startup manager to select the optical, or more simply, hold down the C key as the machine restarts and keep it held down until you see the system loading.

Another G5 iMac won't boot past grey Apple screen!! HELP!!!

Last night I tried to put my iMac to sleep. it took about 3 times, and it finally went to sleep. Today I tried to wake it up but I got the little spinning disk, and it would not wake up. I could not restart it from the screen, so I pulled out the power cord as I have had to do a few times in the past with no problems. Today when I plugged it back in it got to the grey Apple screen, but no little progress circle. I waited & waited, nothing happened so I cycled power again. This time I got the progress timer circle, but again after about 20 minutes nothing happened. I then put the install disc in and booted from that. Tried verify disc, but it failed saying it could not un-mount the volume. Tried verifying permissions, but it seemed to get stuck with just a fraction left on the progress bar, so I quit & tried again (basically where I'm at now). I have also noticed that if I choose the "start up disc" (while running from the disc) the only thing that shows in a network icon. My HD does not show up as an option. For about the past 5 months I have noticed my HD has been a bit noisy. Kind of a whirling sound that seems to get louder then quiet down & repeat....not real loud, but loud enough so I have noticed it. I have been worried that something like this might happen.
update: while repairing permissions I just got a "Disc utility error" says Disc utility has lost it's connection with the disc management tool and cannot continue. Please quit and relaunch Disc Utility. This is the same message I got the last time I tried to run it. I also have an OSX Leopard install DVD...should I be starting from that disc, or the install disc that came with it? If I should be using the newer disc, how would I get the other disc out of the machine?
So....am I up the creek with out a paddle, or is there anything I could try?
any advise would be greatly appreciate as ALL my data is on my iMac and not this POS PC I have to use now.
Thanks,
Jeff

Using Target Disk Mode is an excellent, idea, you should be able to drag your data on to the new machine.
Let us know how you made out,

Macbook won't boot past grey Apple logo.

Hello! 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?
Thanks!

P.S. The one or two times it did get past the mentioned screen, it moved it horribly slow speeds. It took near an hour to get the spotlight feature to open!

Won't boot past grey Apple logo

I have tried presing c but it wont load from the cd drive and ive also tried shift and it wont boot into safe mode. I dont know what else to do.

Your profile doesn't say anything about what model iMac you have, the OS version installed, or any other details about how or when the issue started. If you can give us a bit more detailed information we might be able to provide additional assistance.
How long have you been using this system? Did you recently make any changes to the operating system or install any updates? Do you have your data backed up in case you need to reinstall the OS or reformat the hard drive? Do you have the original install DVD that came with your system so that you can attempt to reinstall the OS?
The issue you described indicates a possible problem with the software on your hard drive which could be due to a variety of reasons including corruption, unsupported sotware, etc. You indicated that the 'c' key didn't allow you to boot from the optical drive. What happens if you hold down the option key when you power on the system? Does it provide you with a list of boot options (eg hard drive, install disk in optical drive, external hard drives connected via USB, etc)? If you get a list of boot options then try booting from the installer disk. The installer disk gives you the ability to run Disk utility so that you can verify whether the hard drive is OK.
Target Disk Mode may provide a method for you to backup your files even if the hard drive no longer boots.

My iMac won't boot past grey screen and it didn't come with a os x disk

My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start 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 the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 10
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 11
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 12
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

PowerBook Won't Boot Past the Apple and Spinning Flower Screen...

I've been reading a lot of these forums, but still haven't figured out how to fix it on my laptop. So, I made my own topic.
Anyways. My dad gave me this laptop since he got a new one, so it's a hand-me-down which means I don't have this startup disk that I keep seeing talked about. I've tried Safe Boot, but when I do it with Command + V, it says all sorts of things that I just don't understand, and there is a lot of talk about the Apple Power Management? Such as:
com.apple.driver.AppleIntelCPUPowerManagement isn't a valid mach-o (magic is cefaedfe)
error mapping module file com.apple.driver.AppleIntelCPUPowerManagement
can't map com.apple.driver.AppleIntelCPUPowerManagement in preparation for loading
couldn't alloc class "AppleIntelCPUPowerManagement"
Etc, etc. And then the last lines that it ends with say:
BSD root: disk0s3, major 14, minor 2
[HCIController][configurePM] power parent ready after 1 tries
And it just stays there and doesn't boot up.
I honestly don't know what any of this means, or if it is even relevant to why my PowerBook won't boot past the Apple screen. If you have any information on how I could fix it, that'd be great. Also, if you have any questions that would help you figure it out, ask away and I will answer them.
Thanks a lot.

MixtapeChick:
Welcome to Apple Discussions. Congratulations on your "new" PowerBook. I suggest that you begin with this combination procedure:
• Shut down the computer.
• Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
• Turn on the computer.
• Press and hold the Command + Option + P + R keys immediately after the startup chime.
• Hold keys down until you hear the startup chime for the third time.
• Release the keys and immediately hold down Shift key to start up in Safe Mode.
• Log in and empty Trash.
• Restart normally and log in.
Let us know how it goes.

Macbook won't boot past main apple screen

I was using my computer this morning (13" black Macbook that I've had since December) and it was working fine until I closed it to go get something to eat.
When I got back and opened the lid again, the screen was black, as if it was off, but I could make out the outline of the Apple logo in the centre. So I turned it off, gave it some time and turned it back on. Now it won't boot past the main Apple screen, where the little timer thing spins and spins and spins while apparently nothing else happens.
I left it alone for a couple of hours, thinking maybe it was overheated, but that didn't make a difference. I tried taking the battery out and restarting it, but that didn't work either. I called Apple, but my parents opted for Future Shop's warranty instead of Applecare, so they told me to search the website as "the issue is well-documented," since I have no tech support with them.
I've searched around to see where this is posted or if it's been answered a billion times before, but it's 35C in here, and my rage/frustration are ruining my ability to be rational, haha.
Anyone experienced this before / is there a resolution that doesn't involve me being without my computer (which is like sweet, sweet crack to me) for an undisclosed amount of time?
Thanks in advance,
Emy
Oh, and I'm not sure about the operating system version beyond that it's OSX and I regularly install whatever updates they tell me to.

Maybe Disk Utility can repair the disk this way:
-Search your installation DVD's.
-Insert the disc 1 and sthut down your Mac
-Start your Mac again while holding down the C key
-Now your Mac should boot from the CD, this can take some time.
-After a while you will see a installation screen where you can chose a language.
-Chose English and continue.
-Then click some time's next and agree with the "Software Agreement".
-Open Disk Utility. Top menu bar --> Utilities --> Open Disk Utility.
-Select your hard disk in the list of disks and volumes on the left side
-Go to the First Aid (tab somewhere on the right).
-Click the button to verify the permissions.
-Then Click the button to repair the permissions.
-Click the button to verify the disk.
-Then Click the button to repair the disk.
-Exit the Disk Utility

G5 won't boot past grey screen

G5 2.0 Dual will not boot past grey screen. Running 10.5.8 on an old maxtor 160gb drive, drive is available as a startup disc in StartUp disk in system preferences. But when it is chosen the machine shuts down in the usual manner then switches to the maxtor disk and only gets to the grey screen with the apple log no progress clock appears. Using disk utility from install disk reports that drive is ok, running techtool pro 4.6.2 reports the drive is fine and all file structures, volume structures and directories are fine. So of course i am keen to find out what the issue is and wether it can be resolved without resorting to a clean install. When booted from another internal drive the icon for the errant drive is visible and all files and folders are visible and readily accessable.
It would be great to get back to booting from this drive as it is the main drive I use and has so much more on it than the secondary drive.
Any help will be of immense use
Thank You

I assume you have already tried a PRAM reset. If so, then the following three items may yield a clue.
Number one thing to try is a Safe Boot by holding the shift key down at boot. You may have a something in the non-minimal Apple kext set that is causing the hang. (If it safe boots, you may have a problem in kext caches which can be cleared. See below.)
Second is to disconnect all peripherals except monitor, keyboard and mouse and see if something there is contributing to the hang.
Third is to use verbose boot (hold down cmd-V at boot until you see a black Unix terminal screen come up) and see where the system is hanging.
Clearing the kext Caches (if indicated)
This is probably easiest done booted from the other drive, so I'll describe that method.
Open the Maxtor's System folder, then open the Library folder and drag the following two files to the trash:
Extensions.kextcache
Extensions.mkext
Empty the trash.
Open a Terminal session from the Terminal application in the /Applications/Utilities folder.
Type cd followed by a space in the command line and then drag the icon for the Maxtor into the window, which will put a properly formatted Unix path into the command line, then press the return key. Type the following three commands
cd System <cr>
cd Library <cr>
sudo touch Extensions <cr>
then give your password when requested and close the terminal session. Select the Maxtor as the statrup drive in System Preferences and give it a go.

Mac Pro 2008 won't boot past spinning wheel

I have a Mac Pro from late 2008 which turns on, makes the startup sound, and remains on the spinning wheel for about 30 seconds before the wheel freezes. I have Windows 8 installed on another internal drive and I can't boot past their version of the spinning wheel, either. I've tried booting off of the install disc (Snow Leopard, which is what the machine is running) and off of a USB stick with a Snow Leopard .dmg on it, neither of which have worked.
I've done all the steps to fix a drive error, so I don't think it's that. I've read that it could be a graphics card error; has anyone else experienced trouble with theirs? Mine was a GeForce 7300, if I remember correctly. Thanks in advance.

It certainly sounds like a graphics card problem.

Power Mac G4 (MDD) Won't Boot, Gives Error Screen "You need to restart..."

Hey guys, I got this Power Mac G4 (Dual 1.42GHz, 2GB Ram) from a neighbor about 3 weeks ago and it has been smooth sailing since I got it. However today my brother was using it, and got the rainbow loading mouse for a long time, nothing would open, I couldn't force quit any of the programs. So I just told him to hold the power button and restart. Well on reboot you hear the tone, then the Apple Logo appears then the screen shows up and says "You need to restart your computer..."
It happens no matter how many times I restart my computer. I've reset the RAM and the PRAM but it does the same thing. Any suggestions?

Oh man, I'm so confused now. I don't know what could have happened.
I put in my Leopard Disc (that I got with my MBP) and booted it from disc, and it said I couldn't install 10.5 because 10.4 or later couldn't be found. That *****, could it be because I was running 10.5.4 and maybe it doesn't recognize it because 10.5.4 came out after this disc was made?
Also, since there are 3 hard drives, I don't know which one I have Leopard on, it's one of the 120gbs, but since this is handed down I don't know which drive is which and I don't know how to take the hard-drives out from the bracket, is there instructions for removing/installing hard drives.
Once again, I appreciate the support, you guys really are helping me!
EDIT: I talked to the guy who gave me this computer, he said that there was a problem with the battery, he said he replaced it about a year ago. Do you think that the battery could be a culprit in this problem?

Help: iMac won't boot past Grey logo screen with spinning lines

My fiance's iMac (intel based) running snow leopard (upgraded from Leopard a couple months ago) will not boot past the logo and spinning lines. This started after at attempting to restart after installing updates to Safari and iTunes.
When booting in verbose mode I get these lines:
Launchctl: Dubious permissions on file (skipping): /Library/LaunchDaemons
Launchctl: Dubious permissions on file (skipping): /System/Library/LaunchDaemons
Launchctl: Dubious permissions on file (skipping): /etc/mach_inid.d

AppleYukon2: RxRingSize <= 1024, TxRingSize 256. RXMAXLE 1024, TXMAXLE 768, STMAXLE 3328
Then it just stops and does nothing.
I've unplugged everything except the apple keyboard and mouse. Ethernet is not connected.
She doesn't seem to have the original disc that came with the computer, but I do have the Snow Leopard upgrade disc.
What do I do? It won't boot in Safe Mode either, freezes at the same spot.
I'm not a particularly savvy Mac user as I recently embraced them when we moved in together.
Any help would be greatly appreciated

Repairing permission is not the first answer. Should try to run fsck and reset the PRAM
Start up your computer in single-user mode to reach the command line.
Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
At the command-line prompt type:
/sbin/fsck -fy
Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:
** The volume (name_of_volume) appears to be OKIf fsck found issues and has altered, repaired, or fixed anything, it will display this message:
***** FILE SYSTEM WAS MODIFIED *****
Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
When fsck reports that your volume is OK, typerebootat the prompt and then press Return.
Your computer should start up normally and allow you to log in.
Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
