-- Posted by MushroomSatsujin at 8:29 pm on Jan. 4, 2009 Ive been having trouble with my macbook. Out of no where, it refuses to boot. I tried running the utilities from the install disk and I get something about an invalid node structure. I check many forums and one solution is to buy a $100 program. That will be a last resort. I bought an external HD to move my files so I can wipe the HD  but I dont know how. I tried terminal but Im not familiar with it. Its locked in var/root and I dont know how to change it or even where that is. Summary: I need to copy my files to and external HD through my install disk.  Mac gurus. help would be appreciated if you could help me fix my laptop. -- Posted by r o c 2 at 8:32 pm on Jan. 4, 2009 nigga you haven't been on here in like........66 years -- Posted by Dr Gregory House at 8:37 pm on Jan. 4, 2009 Here's something, hopefully it'll help: If you have a friend w/another Mac & a Firewire cord, hook up your Macs via the Firewire cord, boot up your friend's Mac, then yours, but hold down the "T" key.  This will make your MacBook a hard drive that you can access with your friend's Mac. If you want to move your stuff to the external HDD, just plug it into the USB on your friend's Mac. After you move everything, you can easily wipe your MacBook HDD with the Leopard install disks. Hopefully I covered everything.  Let me know if it works. -- Posted by MushroomSatsujin at 9:12 pm on Jan. 4, 2009 Quote: from r o c 2 at 8:32 pm on Jan. 4, 2009 nigga you haven't been on here in like........66 years This is why And I dont know anyone with another mac -- Posted by Dr Gregory House at 9:18 pm on Jan. 4, 2009 Quote: from MushroomSatsujin at 12:12 am on Jan. 5, 2009 Quote: from r o c 2 at 8:32 pm on Jan. 4, 2009 nigga you haven't been on here in like........66 years This is why And I dont know anyone with another mac You could TRY it with a PC then...but I don't know how well it would work since they're a bit shoddy anyway. Sorry, that's the best advice I have for you.  :/ You can't access it at all? -- Posted by drifting at 4:23 pm on Jan. 5, 2009 Ok, so heres something you could do. You could make a disk with Ultimate Boot CD or even use a Linux Live CD, and then copy your files over to your external HDD. Another thing you could do is just take it into an Apple store and make them help you with it. Avoid letting them charge you anything by just getting someone in the store to walk you through it.
