A flashing question mark appears when you start your Mac Symptoms

If you see a flashing question mark when you start your Mac, it's probably because it can't find the system software it needs to start up. Usually, all you have to do to get your Mac back up and running is remind it where its software is.
Resolution

If your computer starts up normally after a brief delay, you probably just need to reselect the startup disk in Startup Disk preferences. It's normal to see the flashing question mark when a startup disk has not been selected. In most cases, reselecting the startup disk is all that is required to resolve the issue.

Sometimes, your computer may not start beyond the flashing question mark.

Tip: If your computer has a gray screen (with no flashing question mark) startup issue, see Mac OS X: Gray screen appears during startup.

Check the mouse and keyboard

This issue might occur if a mouse or trackpad button is pressed during startup. Make sure the button isn't pressed.

If the issue persists, shut down your Mac with its power button, disconnect any external mouse and keyboard, then turn on your Mac with its power button. If the flashing question mark issue persists, reconnect the keyboard and mouse.

Additional steps

If your Mac still starts to a flashing question mark, follow the steps below. If any step resolves the issue, you don't need to continue to the next one.

  1. Select your Mac OS X startup disk with Startup Manager by restarting and holding the Option key. After your Mac starts up, restart again to verify that the flashing question mark does not appear.
  2. If the issue persists, insert your Mac OS X installation disc. Be sure to either use the disc that came with your Mac, or, if you installed a later Mac OS X version from disc, use the newer disc.

    MacBook Air note: On a MacBook Air, there are two options for starting up from Mac OS X media: Either connect a MacBook Air SuperDrive to the MacBook Air via the USB port and restart the computer, holding down the C key during startup, or use Remote Install Mac OS X to startup from a system software DVD that's located on a partner computer. Once started up from Mac OS X media, skip to step 3.

  3. Restart the computer, then hold the C key during startup.
  4. From the Utilities menu, choose Disk Utility. Don't click Continue.
  5. Select your Mac OS X disk (named "Macintosh HD" by default) in the left side of the Disk Utility window.
  6. Click the First Aid tab.
  7. Click Repair Disk to verify and repair any issues with your Mac OS X startup disk.
  8. After repairing the disk, try to start up normally.

    Important: If Disk Utility finds issues it cannot repair, you may need to back up as much of your data as possible (or use Time Machine to back up to a different disk), then erase the disk and reinstall Mac OS X. You should back up important files and data before erasing a drive. Erasing deletes everything on the hard disk (including things on your desktop). Also, you can install Mac OS X onto an external disk, start from the external disk, and use Migration Assistant to transfer items from your usual internal Mac OS X startup disk to the external disk, then erase the internal disk and reinstall Mac OS X.
  9. If the issue persists, and Disk Utility didn't find any irreparable issues, quit Disk Utility, quit the Installer, select your disk when prompted, and restart.
  10. If the issue continues, reset PRAM. Note: After resetting PRAM, if the computer starts up normally, reselect the startup disk in the Startup Disk preferences.
  11. If none of these steps resolve the issue, start up from the Mac OS X Installation disc and reinstall Mac OS X.

Macbook air A1466 starts up with a question mark folder


That's the traditional Apple icon for 'Where's my hard drive?' The computer can't find the hard drive to load the operating system. Either something has come loose, or your hard drive is damaged. They are replaceable, though it would be simpler to return it to Apple, if it's still under warranty. OWC (Other World Computing) rather famously figured out how to replace the hard drives, even though they were not intended to be replaceable. They have several fairly inexpensive models, and their website has several videos that walk you through installation. If you don't want to work on it, you can take it to an Apple Authorized repair center, and they can repair it, though it may be a bit more expensive.

My apple macbook air shows a question mark when i turn it on


Resetting the PRAM may do the trick:
You reset the PRAM by rebooting a Mac and then immediately hold down the Command+Option+P+R keys, you will then hear the Mac reboot sound again, signifying your PRAM has been reset. You must hit the key combination before the grey screen appears otherwise it won't work.

you've tried rebooting, you've reset the PRAM, you've done it all, but your Mac is still behaving strangely. What next? In certain circumstances, resetting your Mac's System Management Controller (SMC) can be a solution. This is sometimes necessary to restore normal lower level system functionality to your Mac.

Here's how to reset the SMC on any type of Mac (and any version of OS X) and the type of problems that it may resolve.
When & Why Reset SMC on a Mac? Some Common Hardware Reasons

Typically it's power and hardware related issues that can be helped or resolved by resetting a Mac SMC, particularly if you're having these types of problems:

* Issues with your Mac's cooling fans and fan management: fans run constantly at high speed, fans run high despite low CPU usage and adequate ventilation, fans not working at all, etc

* Power management and battery problems: Mac isn't turning on, sleep isn't working, random shutdowns and reboots, battery isn't charging, Mac won't wake from sleep etc

* Light problems and improper lighting management: battery indicator lights aren't working, display backlighting isn't adjusting to ambient light changes, keyboard backlights not working, etc

* Video and external displays not working: display brightness functionality not working properly, target video mode isn't working properly, external display isn't working, etc

* General performance and functionality problems: abnormally sluggish behavior despite no CPU or disk usage, external ports not working, airport & bluetooth aren't showing up, external devices are not being found, etc

So now that you've concluded you need to reset your SMC (Note that the SMC is on Intel Mac's only), here's how to do it on MacBook's, MacBook Pro's, iMac's, Mac Mini's, and Mac Pro's. Notice that the reset instructions are different for MacBook and MacBook Pro's if you have an internal or detachable battery.
Reset SMC of a MacBook Air, MacBook Pro Retina, or MacBook Pro's with an internal non-removable battery

This is how to reset SMC on most modern Mac laptops:

Shutdown your MacBook Air / MacBook Pro
Connect the power adapter to your Mac
On the MacBook/Pro's keyboard, hold down the Shift+Control+Option keys and the Power button at the same time
Release all keys and the power button at the same time
Boot your Mac as usual

Here's the key sequence to hold down:

Reset the SMC of a MacBook Air or Retina MacBook Pro

Do keep in mind that by resetting the SMC you will lose power specific settings, like the time it takes to sleep a Mac and other customizations to power settings. No big deal, but if you have made many changes to your hardware behavior you will want to adjust stuff like sleep behavior again.
Reset SMC of an iMac, Mac Pro, Mac Mini

Resetting SMC is different for non-portable Macs:

Shut down your Mac
Disconnect the power cord
Press and hold the Mac's power button for 5 seconds
Release the button
Reattach the power cables and boot the Mac as usual

Reset the SMC of a MacBook or MacBook Pro's with detachable batteries

mac reset the smc Older MacBook laptops with a removable battery can reset SMC with the following approach:

Shutdown the MacBook/Pro and remove the battery
Disconnect the power adapter, hold the Power Key for 10 seconds
Release the power key and reconnect your battery and power adapter
Turn your Mac on
Let boot as usual

Hopefully that will clear up your problems, if not it might be worth a visit to the Apple Store or a certified repair center.

Happy New Year,
Kerry

I have a macbook laptop with damaged dvd cd drive. I am getting a white screen and folder with a question mark when i start up computer. What is the problem and how do i fix it?


The folder with the question mark indicates that the computer is unable to boot (start) from the hard drive. I would ordinarily tell you to put in your system disc and boot from it to use Disk Utility to fix your drive. But you say your DVD burner is broken.

1. Hold down the power button to turn off your machine.
2. Hold down Command and S together and press the power button to turn the machine back on.
3. It will boot to a black screen with white text. Once it gets done, type

fsck -fy

and press the Return key. This will check and hopefully fix your drive.
4. Once it's done, it will either say, "This disk appears to be okay." (or something like that, or "File system has been modified." If it says that the file system has been modified, return to step 3 and type fsck -fy again (and then press Return).
5. Once you see the message that the disk appears to be okay, type

reboot

and press the return key.

Hopefully your machine will boot up successfully. If so, please leave a comment so we know it worked (and please give me a good rating). If not, leave a comment with details and we'll try something else.

Good luck!

The computer cannot find the operating system files to start up. Use a start-up disk or utility disk to start the computer then re-install the system files.Hold down C key while starting from disk. DO NOT REFORMAT the disk or you will lose all your files. Just do a simple System install.

You have a disk/file system problem. Use your system install disk and in Dish Utility, repair and when OK, fix permissions. Do this after each install--can usually just use DU and verify+fix. If you must, then boot in Target mode (hold T on boot) and connect to another Mac, Use Firewire, if can, else may need to remove disk and put in external. If no fix, then will need re-install.
