    Firstly, my com.apple.Boot.plist contains the following

    Code:
    bplist00“VKernel\Kernel Flags[mach_kernel[arch=x86_64
    !-9
    Any info I've found on booting to 64 bit tells me to find

    <key>Kernel Flags
    </key><string></string>

    and change it to

    <key>Kernel Flags</key>

    <string>arch=x86_64</string>

    Is something wrong with my file? What does your com.apple.Boot.plist contain?

    no need to mess with that file
    open terminal

    and type

    sudo nvram boot-args="arch=x86_64"

    note the punctuation type it ALL in

    hit enter type in your password

    reboot

    if it plays up just reset the pram P R alt cmd and restart wait for four boings and you will be back as you was

    Your com.apple.Boot.plist is in binary format. You can convert it to text with the following command:
    Code:
    $ sudo plutil -convert xml1 /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
    .plist files can safely exist in either format, the OS loads them faster if they're in binary. There's no reason to convert it, though. Just follow Lordedmond's instructions.
