Http://forums.macrumors.com/forumdisplay.php?f=129 Look here first as I'd need more info prior to Guestimating the cause.. (Were Swamped).. Any way post back.. Sounds like drive failure to me or similar/OS Issue but could be more. Is the flashing/Change Timed or an Intermittent thing..

Good luck!

Brand new apple dvd drive will not accept dvd


The DVD works by just pushing it in far enough till you get resistance, then the drive pulls the DVD in by itself. If after it pulls the DVD in, it just ejects it, The DVD drive thinks you are using an incompatible disk.

You can also try resetting the SMC.
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

sad 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

Start problem


Hi, Sorry to hear you are having problems,
You are describing something quite strange, normally, you get one of those 3 images.
The circle with a slash through it indicates that your system cannot boot that model Mac.
The folder with the ? flashing indicates that a Boot drive cannot be found.
And the Apple Icon indicates that the system is now Booting.
So, your MacBook Pro is suffering from multiple personality disorder.
You would do best to re-install the system right over your old system using the ( Archive and Install ) Option making sure you keep your existing users.
Also, be sure to run Disk Utilities before installing the System, run Repair Disk and Repair Permissions on your internal drive a few times until there are no more problems found, then install.
Once you have done this, your Mac should boot up properly. You will then need to run Software update a few times until there are no more updates.
Sounds intimidating, but don't fret, it's one step at a time..
