Question about Apple PowerMac G5 Dual Mac Desktop

1 Answer

My Apple Mac keeps giving me a message telling me to restart but when I do, the apple screen appears with small wavy red lines through the apple. It then goes to the blue screen and finally flips to

Using Tiger OS 10.4.11 Iniitally the computer re-started up properly and I was able to work for a short while before getting the restart message again. I was also able to access a second internal hard drive and ran Disc Warrior for the main drive from this. All repairs were completed but it was only after this that the computer failed to restart at all past the grey/red wavy line screen.

This could be anything and will take a workshop to diagnose correctly.The power-supply unit in these Macs was particularly problematic and it could easily be that but without a worksop visit it's im[possible to tell.

SOURCE: The computer comes on but is frozen on Apple screen

I would try pressing f2 or f8 when first boots up, then change bios settings from first bootup device as cd rom drive, then hard disc as second drive, then place windows disc or recovery disc in pc, then reboot. and reinstall your software.

SOURCE: Computer freezes at grey screen

  1. Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.
  2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
  3. Click the First Aid tab.
  4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
  5. Select your Mac OS X volume.
  6. Click Repair. Disk Utility checks and repairs the disk.

SOURCE: APPLE IMAC G4 - TRYING TO INSTALL OS WITHOUT DISK EJECT BUTTON

Reastart the iMac and at the same time hold down the mouse left click button. If that does not work.

  1. Restart the computer.
  2. Immediately after the startup sound, press and hold the key combination Command-Option-O-F.
    Note: The Command key has the Apple and (commandkeysymbol.gif) icons on it.
  3. Release the keys when you see a white screen that says "Welcome to Open Firmware."
  4. At the prompt, type: eject cd
  5. Press Return, then wait a few seconds. The disc drive should eject any disc that is present, and "ok" appears behind your command when the action is complete.
  6. Type: mac-boot
  7. Press Return.

SOURCE: wont boot on its own, wont boot with install disc,

As the hard disk appears to be showing up when you boot up using the install disc, I would suspect that the system is somewhat corrupted. You could reinstall the system again and if you are happy starting from scratch and wiping the hard drive select this option failing that and there is some data on the imac you could install using the preserve user data. A fresh install should sort out any problems. Hope this helps.

Download the latest iTunes to your computer and reset the iPhone. Then re-sync it.

Reset


To reset iPhone, press and hold the Sleep/Wake button and the Home button at the same time for at least 10 seconds. During this time, a red "power off" slider may appear and the screen may go black, but do not release Sleep/Wake and Home buttons until the Apple logo appears.

If iPhone won't turn on, or the display freezes or doesn't respond

  1. Press and hold the Home button for at least six seconds, until the application you were using quits.
  2. If that doesn't work, turn iPhone off and turn it on again. Press and hold the Sleep/Wake button on top of iPhone for a 10 seconds until a red slider appears, and then slide the slider. Then press and hold the Sleep/Wake button until the Apple logo appears.
  3. If that doesn't work, reset iPhone. Press and hold the Sleep/Wake button and the Home button at the same time for at least ten seconds, until the Apple logo appears


More resets:

Try This:
1. Remove Sim Card

Hard disk crashed on macbook


You can tell if your hard drive for your Macbook Pro has really crashed, if you attempt to run these 3 diagnose and repair procedures and there is no response from the hard drive:

1st Procedure:

font.f1 {font: 12.0px Helvetica} font.f2 {font: 14.0px Myriad Pro} - USING FSCK COMMAND TO VERIFY AND REPAIR DISK-
Start up your computer in Single-User Mode to reach the command line by doing this:
•Make sure your Mac is shutdown.
• Reboot your Mac
• When Mac starts up, press the Apple Command key+ S Key
- A black screen, with white text appears
• At the command-line prompt, type /sbin/fsck -fy
• Press Return.
--fsck will run through a series of tests and will return information about your disk's use and fragmentation. When completed, it will display this message if no issue is found:

The volume (name_of_your_Mac_volume) appears to be OK

If 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 at the beginning, 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, type reboot at the prompt and then press Return.
• This last command after completing the fsck process, is going to attempt to boot your Mac to the main desktop.

If unable to reach your Desktop with the fsck procedure, go to the next step.
----------------------------------------------------------------------
Procedure # 2
font.f1 {font: 13.0px Myriad Pro}
-RUN DISK UTILITY WITH STARTUP DISK-

Insert your Mac OS X Startup disk
•Reboot your Mac
•At the Apple Chime, press the C key and hold it until you see a White screen, gray Apple and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.
•Mac will boot from the startup disk to the Installer environment
• From the Installer Menu bar, click Utilities > Disk Utility and open up Disk Utility application.
• Click on on the hard drive at the top of the window in the left sidebar and
• Select "Repair Disk"
**Let Disk Utilities run this repair the disk until completion
• At the end of this process, reboot your Mac

* If you have still not gotten a successful boot to your main desktop, try this final step.
----------------------------------------------------------------------
Procedure # 3
My recommendation for this issue, is that you use the Archive and Install procedure to resolve this issue.

What this process consists of (using your Mac OS X install disc),is removing the damaged or corrupted Mac OS X directory and replacing it with a brand new directory.

This procedure also allows you to save your applications, files and folders without the old directory interferring with you then accessing those files.

-ARCHIVE AND INSTALL-

• Start up from your Mac OS X Install Disc 1 or Install DVD. Please remember to use the install disc that matches the current operating system your system haves.

Usually, you can start from the disc by putting it in your computer, restarting, and holding the C key.
• Hold the C key until you see a White screen, with a Gray Apple icon and eventually a Spinning gear.
• Release the C key only after you see the Spinning gear.

-Your mac will now boot from the disc and load into the Installer environment.

• Select your language. The Welcome to the Mac OS X Installer window appears.
• Click Continue. The Important Information window appears.
• Follow the prompts until you get to the licensing agreement screen
• An agreement sheet appears. If you agree with
the license agreement, click Agree. Then Select a
Destination window appears.
• Click the volume that you wish to install to (your primary hard drive).
• Click Options. The installation options sheet appears.
• Select Archive and Install.
• Select the volume which already has Mac OS X installed.
• You should also select Preserve Users and Network Settings, to preserve network and Home directory settings.

• Click OK.
• Click Continue to begin the installation.
• Once the Archive and Install is completed, when you reach your desktop be sure to run all Software updates to bring your new Mac OS X directory back
up to current.

Also, if you look inside your Macintosh HD icon on your Desktop, look for a folder entitled "Previous System Folder" which will have all of your previous Home folder files prior to the Archive and Install.

Here is the link (below) from Apple for more information about how to locate the Previous System Folder

How to locate Previous System Folder (after Archive and Install)
----------------------------------------------------------------------
If there is still no responsiveness of the hard drive after this last procedure, your best option would be to take your Macbook Pro in for repair or replacement of the hard drive, to your local Apple retail store Genius bar or local Apple authorized service center.

Best Regards,

Stuck on the restart your computer screen.


You may have installed something in the startup items folder that your mac isn't liking. 
When you turn the iBook on, press the shift key as soon as you hear the startup tone. hold it down until you see the gray apple screen. This will get you into safe mode, hopefully then you'll be able to fix whatever you did from there. If you are still at a loss, get in touch.

Repated start up requests from the computer


That means Hardware Error. It is a gray iron curtain with a black dialog box. Most likely bad Ram/Memory, but If warranty, call Apple. Otherwise there should be a diagnostics CD or DVD that came with your recovery Disks. It should tell you what's wrong if it can boot before the Iron Curtain comes down again.
You can try swapping ram with a recent age mac or pc laptop and see if it repeats.
