Help with the spinning startup icon on Macbook Pro

Hi,

I'm working on a Macbook Pro A1278 and upon startup get the spinning icon with the apple logo in the center.  What is the best way to approach a fix for this?

Thank You

Try a safe boot by holding down the shift key.

Well it started to show a progress bar while holding shift then about a third of the way through it went away and continued with the original issue.  Also tried just get the bar started and releasing SHIFT, same result.

Do you still have the original startup CD? If so, start from the CD by holding down the c key. Then pull down the Utility Menu to Disk Utility and run Repair Disk.

try the procedure below.

turn OFF. restart by holding apple+S key. keep the buttons held down until you see black screen with loads of white text.

next on root: type     /sbin/fsck -fy   (remember the spaces)

after that completes (may take some time),  type /sbin/mount -uw /
you will see the shell prompt again, now type rm -rf /library/caches


then press reboot once it finishes. make sure you put spaces right in the above command or just copy it from here.


see if that helps

Try putting the CD back in and this time boot while holding down the option key until the boot picker comes up. If the CD does not show in the boot picker, either you are using the wrong CD (i.e. not the one that came with your particular Mac), or there is a problem with your CD drive, or you have a hardware problem with your computer.
