I tried updating to snow leopards by downloading the file and burning it onto a DVD. The update was installing and then my computer restarted.


It was stuck on the rotating wheel and apple logo for the longest time. I tried restarting the PRAM and that seemed to work to bring me to my login screen. However, now my mouse is stuck in the top left corner of the screen and my key board is unresponsive.


Please help!

MacBook (13-inch Aluminum Late 2008), Mac OS X (10.5.8)

    Can't do it that way.   You basically have now installed a corrupted Snow Leopard, if you downloaded it off the internet.  Snow Leopard is Mac OS X 10.6.    Snow Leopard is not available from Apple for internet download.  Any internet download site having it is likely filled with malware.    I hope you backed up your data before doing that.    Apple offers Snow Leopard on DVD still at their store:



    Additionally there are these pitfalls to watch out for when installing Snow Leopard:


    To recover lost data if you didn't backup, see these directions:

    The 1-800-MYAPPLE store will sell you the 10.6 installation CD. If your data is backed up, just simply boot the installer disc, and run disk utility to reformat the hard drive. Then install 10.6 from scratch, and restore your backup.


    If your data is not backed up, use a data recovery tool mentioned in my tip 1689 above to recover the important data to an external drive, before erasing the internal drive, and installing 10.6 from scratch.

    Once you have verified all your applications work with 10.6, then you can go ahead and upgrade to 10.6.6 or later to use the Mac App Store.

    Your machine is the minimum MacBook that can install 10.8, but you'll need to upgrade to 10.6.8 first, and make sure all your applications are Universal and have no PowerPC requirements, and make sure you have a minimum of 2 GB of 2 GB of RAM, and 15%+8GB of hard disk space free.

    For more on 10.7 compatibility see: https://discussions.apple.com/docs/DOC-2465 and 10.8: https://discussions.apple.com/docs/DOC-3761


    Don't ever use torrents, limewire, or other peer2peer software to download operating systems.  Their safety can't be guaranteed.

    Hi a Brody,


    thank you for all your help.


    Can you please let me know how to boot the installer disc and run disk utility if my key board doesnt work?

    You need a wired Apple USB keyboard.  See my tip on using the startup manage which is both in the 2455 and 3761 page. Disk Utility is part of the Intaller menu that appears after you select the language for the installer.
