    My MacBook intel core duo won't star up. I turn it on and I get the Apple sign and then the loading cycle doesn't stop. I've already tried going into my install disk and disk utilities and then repair the disk but it didn't help. Is there anyway to get it to work without wiping my entire harddrive?

    tried taking my battery out and putting it back in... no gold...

    i had just used software update to install an update... could that be a part of the problem?

    How long are you letting it run for before manually shutting it down? If you've just installed an update, it could be installing the update before booting and you're just canceling it over and over.

    i let it sit through my entire math recitation (somewhere near 50 minutes) with the load wheel spinning the whole time...

    do i need it to sit longer?

    HEre's what I'd do then post the results. Press and hold CMD+OPT+O+F when you boot up your mac, before the chime, and hold it till a white screen with grey text comes up. Type in these commands:

    Now once that is done, it'll restart. After that if it still doesn't load up, boot into single user mode: CMD+S before the chime. And when it loads it'll tell you the commands to type in, type those in and it'll log the OS as it loads, let us know what it says in there if the prior doesn't work.

    I'm stuck...again...

    Here's where i am at..

    1. i downloaded the update and put it on a usb memory stick. I put the memory stick into my mac.

    2. i inserted my tiger instal disc and used it to run terminal.

    3. in termial i inserted

    cd "/volumes/<my HD name>"
    "/volumes/<My HD name>/usr/bin/open" /volumes/<Mymemorystickname>/MacOSXUpdCombo10.4.11.dmg

    this opened my disk utility which caused the MacOSXUpdCombo10.4.11.dmg to show up on the left hand side with a hard drive icon.

    i don't know what to do from here....

    (i am trying to finish what is assumed to be a failed update)

    -slookster- i couldn't get the command "CMD+OPT+O+F" to work nor did i recognize the commands told to me in single user mode.. sorry.. i am kind of new to this...

    any help would be great!

    (insult to injury: in desperation i went to the mac store today to see the genius bar, but they were completely booked and couldn't see me... you are my geniuses now! help!)

    this is what you'd execute next from that point:
    "/volumes/MacBook HD/usr/bin/open" /volumes/<mounted dmg volume name>/MacOSXUpdCombo10.411Intel.pkg

    i was installing 10.5 on my friends MBP. all went fine until we updated to 10.5.1 through software update. Something happened in the middle of the new files overwriting the old ones. The only fix i got was to insert the leopard install disk and boot the computer from the cd and do a fresh install. ...glad it wasnt either of my computers, but his mbp needed it.

    Okay, I fixed mine after much stress. I had to reinstall Mac OS 10 by doing an Archive and Install and then started kind of fresh, good God that was scary!

    Call me curious. But what did you do to your Mac prior?
    Did you force shutdown via the powerbutton? Download some updates? Shut down the system using the Apple Menu... What?

    Just to note in this thread:
    As much as I enjoy google products, DO NOT install Google Desktop for Mac OS X, as it will hamper/slow down/kill your computers startup. I had Google Desktop on my iBook and tried to upgrade to Leopard, it crashed it, the launchdaemon's get stuck so you have to boot into single user mode (SUM) and remove them from the launchdaemon's (anything google) and launchagents in /Library/ folder, I think it may also embed itself into /System/Library as well.

    same trouble..

    Hi guys,

    I'm now starting to freak out since my 6 month old MBP doesn't start anymore. Well it successfully started but I didn't have an internet connection and I restarted it from the apple menu and it never starts anymore.. It just got stuck in a white background (with apple logo in the center) and this rolling wheel and that's it.. I've tried tips from the manual like disk utility and booting it up and pressing CMD+OPT+O+F to no avail.. Please help...

    Thanks in advance,

    Search around on here, there's some useful stuff. Probably a software fault, not hardware. Try
    - resetting the SMC
    - booting into safe mode
    - booting from your install DVD (insert it, press option and select DVD)
    - booting from your backup if it was made with SuperDuper (you have a backup.... right?)
    - Hardware Test on the DVD

    The Apple site or searching here will tell you how to do these things.

    If it boots from DVD you've got a corrupted file system or hard disk failure. If it doesn't boot from DVD come back on here and let us know.
