editing com.apple.Boot.plist to boot Snow Leopard in 64 bit

[jamesrp]

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

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:

$ 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.
