    Hi there,

    Try holding down the alt key or option key on your keyboard to select which drive the operating system is located on.

    if that doesn't work,

    Try holding down the " comand" and "v" keys on your keyboard as it loads, this should load it in verbose mode to troubleshoot it further.

    Let me know how it goes.

    Hope this helps,

    Nathan.

If that does not work, when you turn on the computer, hold the "Command" and "S" keys, this should boot to single user mode. When finished, it will dump you to a command prompt. From there type "/sbin/fsck -fy" (no quotes) and press enter. That wil run the BSD Filesystem Check. Once that is complete, type "reboot" and hit enter.

If there was an error with the file system that was keeping you from booting, that will solve it.

You can turn off the machine by pressing and holding the Power button until the display switches off.
Then, try resetting your 'PRAM' using the following instructions;

I've used every version of OS X from 10.0 through to 10.5.6 and sometimes you get this problem after an incremental upgrade. It usually just goes away after a couple of reboots.
Please let me know how you go.
Thanks,
Sean

Macbook stuck on load up screen


When you say "load up screen", I assume you mean the Apple boot screen (it has the apple on a gray background).

You might try resetting the PRAM on the macbook.
You can do this by pressing and holding the Command-Option-P-R keys. You must press this key combination before the gray screen appears.

So, turn the macbook completely off. Turn it on and immediately press and hold the Command-Option-P-R keys until the computer reboots and chimes. Once it chimes, release the keys. Your system should boot normally.

My computer keeps shutting down irreglarly


Hey Henry,

Try reseting your PRAM and SMC.

Here's how to reset your PRAM:
  1. Shut down your machine. Yes, all the way down, not sleep or logging out.
  2. Press the power button and then press command-option-p-r. You have to make sure you get those keys pressed before the gray screen comes up or it won't work.
  3. Hold those keys down until your Mac reboots again and you here the startup chime.
  4. Let go of the keys and let your Mac reboot normally.

For SMC:


  1. Turn off your machine
  2. Keep the MagSafe adapter plugged in.
  3. Press at the same time shift-option-control (on the left side of the machine) and the power button
  4. Let go
  5. Turn your machine back on with the power button.

My apple macbook air will not reboot. it turns on but does not reboot completely then it shuts down and tries to reboot again and again. apple logo appears and the spinning icon rotates but never goes...


It may be a possibility that the hard drive has gone bad or a connection to the hard drive. The spinning wheel and apple signify the kernel boot, or in other words, the process in which the machine finds the hd and os/software.. you need to bring your machine into an authorized repair center to have a system diagnosis to verify that no other parts of the machine are bad. That model is notorious for having bad hd's.

We downloaded a programme called Snowflake and the Macbook pro froze and since we are not able to get past a snowflake screen since rebooting. We have tried everything can you advice how to troublshoot...


You need to start up in osx safe mode, and delete the application.
To start up into Safe Mode (to Safe Boot), do this:
  1. Be sure the computer is shut down.
  2. Press the power button.
  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).
It takes quite a while to start up.

Blinking file folder with question mark and a DVD is stuck in it


Hello, The blinking file folder with the question mark can happen when the computer doesn't "see" your System. It can be caused by a faulty hard drive, or by a damaged operating system. You can try to reboot the mac, hold the mouse button during 20 seconds to eject the CD, then insert you installation DVD (leopard). Reboot the Mac again, and hold the "C" key. Select english, the go to the tools menu, and Disk Utility. Go to the SOS tab, select your drive and click "repair". If something red appears, it means that it has found something wrong on your hard drive. Best regards

Completely white/gray screen


First try this: shut it down, disconnect the power cord, pull out the battery, then hold the power button for a full 10 seconds. Reinstall the battery, reattach the power cord, turn it back on.
Still doing it? Put the reboot disk that your Mac came with, or the disk to the version of Mac OS X that you're running.
To start from disk hold "C" as your Mac is first turning on from a complete shutdown.

MacBook wont run from battery


Apple does have a battery recall/fixing procedure on certain macbooks and macbook pros.

The battery of a MacBook or MacBook Pro computer may:
  • Appear to have no charge (zero percent)
  • Be unable to power the computer by itself; the computer might work only when it is connected to the MagSafe power adaptor, which only shows a green LED
  • Appear with a black "X" icon on the menu bar

  1. Shut down, then remove and reinstall the battery. Test for the issue(s) again.
  2. Connect the MagSafe power adaptor (if you haven't already) and see if the behavior continues.
  3. If the issue(s) persist, download and install the Mac OS X 10.4.9 Update.
  4. If the issue(s) persist, Download and install Battery Update 1.2.
If, after installing the Mac OS X 10.4.9 Update and Battery Update 1.2, a black "X" still appears in the menu bar, contact apple by calling 1-800-MY-APPLE (1-800-692-7753)
