    Exactly which line did you change? You can probably fix it in single user mode.

    Change it back with single user mode then fix permissions. Once done, reboot to exit single user mode.

    You, deleted it? Start it up in single user mode, Command-S right after the chime. Then, run the following commands:
    Code:
    /bin/mv /System/Library/CoreServices/SystemVersion.plist /System/Library/CoreServices/SystemVersion.plist.brk
    Press enter, you may get an error about file not found. Ignore it. Then run this command, substituting the name of your flash drive in the %FLASHDRIVE% area. This command assumes that your backup SystemVersion.plist in at the root of your flash drive.

    Code:
    /bin/cp /Volumes/%FLASHDRIVE%/SystemVersion.plist /System/Library/CoreServices/SystemVersion.plist
    Press enter. Then restart it with:

    Code:
    /sbin/reboot

    Where on your USB flash drive is the file stored and what is the exact name of that flash drive?

    You could possibly pull the one off of the reinstallation disc and correct it's versions to be what the system really is.
