Two possible things are wrong either your hard drive has gone or your system has corrupted.

If your system is corrupted put your instal disk in start it up holding down the c key. Once it has started check that the hard drive exists by go to the menu bar and selecting the disk utility. If the hard drive shows it means that it is okay so run the disk utility check drive and then run the repair permissions. Then try restarting, if it works then you are back up and running again. If the drive shows up and you restart and the same thing shows up, you will need to reinstal your system. You do this by starting up with the instal disk holding down the c key and run the instal script. To keep your hard drive contents your will need to use the preserve users instal.

If your hard drive does not show up the hard drive is probably a gonner and you will have to purchase a new hard drive and then instal a fresh system.

Hope this helps

My Macbook pro turns on but then gets stuck at the Apple logo with the loading gear and never finishes loading.


See if you can start your Mac in safe mode:

Shut down your Mac and wait 10 seconds.
  1. Press the power button.
  2. Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.
  3. Release the Shift key when you see the gray Apple logo and progress indicator (spinning gear).
To leave safe mode, restart your Mac normally without holding down any keys during startup.

If you can boot in safe mode, you have something on board your computer that's interfering with startup. If you've recently installed software, system extensions or 3rd party preference panels (Adobe and Microsoft stuff is notorious), try to disable or de-install it. If you can't get booted in safe mode, you may have a hardware or memory problem that might require technical repair. Repost your progress.

Starting iMac OS 10.6.8


Hi Jan,

If you see a spinning grey earth globe, then it's an easy fix.
Starting from a shut down mac, press the start up button then immediately press and hold the Alt button until you see your startup disk appear, release the Alt button, ... select your startup disk and then hit return. The mac should boot up normally.

then immediately go into the System preferences and choose the StartUp Disk icon and make sure you select your harddrive as the start up disk. somehow, network disk was selected and it is timing out looking for it...

MacBook won't start up.


If you have your Mac OS X Install disc, insert it into the drive.
Restart the computer and hold down "C" while booting.
Choose your language.
Select "Disk Utility" from the "Utilities" in the menu bar.
Select your Macbook's hard drive in the left sidebar.
Click the "First Aid" tab thats along the top of the viewer window.
Click "Verify Disk" (not verify disk permissions)
If this shows errors click "Repair Disk"
Once completed close the Disk Utility window.
Restart the computer.
If this fails to fix it as well then your next option would most likely be recovering your files from the macbook either by booting into target disk mode (hold down T at startup) and transferring them via a firewire cable, or removing the hard drive and hooking it up to another Mac to get the files. Then do a clean install of Mac OS X using your installation discs.

Damaged 24 iMac screen - want to use ext monitor via "mirroring" in screen preferences, but cannot access system preferernce due to damaged screen...any suggestions


There is an elegant way to solve this, but it requires another compatible model Mac.
Boot the damaged Mac into FireWire Transfer mode by holding down the "T" key immediately after hearing the startup chime. Attach a FireWire cable between the two Macs. Start up the other Mac by holding down the "option" key after hearing the startup chime. Choose the startup drive from the broken Mac. Now your good Mac is booted off the drive of the broken Mac, and any configuration changes you make will be made on the hard drive of the broken Mac.
Attach the external monitor temporarily to the good Mac. Open System Preferences and set the monitors up in mirrored mode. Shut down the good Mac. Then hold the power button in on the broken Mac until the power turns off, and remove the FireWire cable.
Now move the external monitor to the broken Mac and boot it. It should come up in mirrored mode.

I have a G5 2.3 dual core running 10.4 I need to repair the system but have lost my install disc. Do you know where I can get one? Roderick Duncan


To start up in Safe Mode, hold down the shift key and then startyour Mac. Safe Mode takes a while, so don’t be alarmed when you don’tsee the desktop right away. While you’re waiting, the operating systemis verifying the directory structure of your startup volume, andrepairing it, if necessary. It will also delete some of the startupcaches that may also be preventing your Mac from starting successfully.
Once the desktop appears, you can access and run disk utility http://macs.about.com/od/applications/ss/firstaid.htm tool just as you normally would. When First Aid is finished, restart your Mac normally.
Please note that not all applications and OS X features will workwhen you boot into Safe Mode. You should use this startup mode only fortroubleshooting and not for running day-to-day applications.
Boot Into Single User Mode Start up your Mac and immediately hold down the command key plus theletter ‘s’ key (command + s). Your Mac will start up in a specialenvironment that looks like an old-fashioned command line interface(because that’s exactly what it is).
At the command line prompt, type the following:
/sbin/fsck –fyPress return or enter after you type the above line. Fsck will startand display status messages about your startup disk. When it finallyfinishes (this can take a while), you will see one of two messages. Thefirst indicates that no problems were found.
** The volume xxxx appears to be OK.The second message indicates that problems were encountered and fsck attempted to correct the errors on your hard drive.

  3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
  4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).

APPLE MACBOOK WOULD BOOT. THE BOOT CD IS


unfortunately on the newer mac computer including the macbook you cannot boot to open firmware but there are other options
option 1)simply try holding down the mouse button or track pad button during boot after the first chime is sounded this will instruct the computer to eject the cd through the firmware
option 2) you can bypass the cd boot by holding down the option key after the first boot chime another simple solution this will allow you to choose a startup disk during...startup after which you can try the eject button on the keyboard or select the disk in finder and eject via trash can or eject symbol(symbol located in the open folder view of finder)
option 3) there is also a manual eject button though it may be harder to locate as they have change placements of it over the years however it can usually be found by probing the top center or far right of the cd slot with a paper clip just be gentle you don't want to damage an expensive piece of equipment by just carelessly jamming metal in it
you may want to try searching apple with your particular model and search for manual cd eject
best wishes, Crash

Changing mac preferences in single user mode


Start your computer by holding down the option key before pressing the start button. This should give you an option to choose which startup disc to use when starting the computer. Once it's restarted, go to the System Preferences and choose the specific startup disc that you want to use.
