A friend of mine brought me his MacBook to see if I could bring it back to life, and I have to say I failed. This is what happens. On booting, the Apple icon comes up, and then the spinning wheel starts up . . . and keeps going and going and going. My friend says he's let it run for hours, and it doesn't get beyond the spinning wheel.

This is what I did. First, I reset the P-RAM. No joy.

Then I booted into single user and ran fsck. No joy.

Then I connected to my laptop via T-mode and ran DiskWarrior. No joy.

Then I did the same and ran TechToolsPro, fixing the volume structures. No joy.

A SMART check showed the HD was OK.

I then booted the MB from the TechToolsPro disk--and it booted fine, and ran the RAM check, which showed that the RAM was ok too. Still no joy.

I can't figure it out. The software checks say things are OK, and the hardware checks say things are OK.

My friend has left, but I'm wondering if there's something else he could do.

Since a MacBook maybe got dropped ? so could be a lose transistor or controller connection ?

Sometimes, the hard drive will pass all the checks and still be going bad. Since it boots from the CD/DVD drive, I'd suspect the HD or the HD controller.

The spinning grey wheel means that the operating system is going through checks, maintenance and corrections. Something in the operating system is out of whack and cannot be corrected. Have you tried a clean system instal on a reformatted HD?

It's either that, or it cannot find the needed files on the HD. Is there a bootable DW disk handy? Sometimes, a complete rebuild of the disk directory will fix it if the HD isn't going south.

I ddi the complete rebuild with DW, and that didn't work. I thought of doing a clean install, but he hadn't backed up the drive, so . . . .

Does the drive mount on the desktop when booted from the CD/DVD? Maybe you could boot from the CD/DVD drive and connect it via ethernet to another computer and mount the drive on that computer to get the needed files off it?

Yeah, I mounted the drive via target disk. So it's definitely possible to get the documents. It'll just take a while to do it, and he had to leave. I wish I'd asked if he wanted to leave the computer with me--I could be doing it now.

Connect the MacBook via Target Disk mode to an Intel machine and run the latest combo updater on the MacBook.

Worth a try, I've fixed 'em that way before.
