Option 1: 1. Enable root (http://snowleopardtips.net/tips/enable-root-account-in-snow-leopard.html) 2. Make the edit 3. reboot Option 2 (Safer for novices): 1. copy the file to the desktop 2. edit the file 3. copy it back to the location 4. open Terminal 5. In Terminal you will need to input the following entries* (you can copy and paste the commands) sudo chown -R root:wheel /Library/Preferences/SystemConfiguration/com.apple.boot.plist sudo chmod -R 755 /Library/Preferences/SystemConfiguration/com.apple.Boot.plist 6. For good measure open Disk Utility and repair permissions. 7. reboot. The reason for either of these procedures is that the file being edited is a System file. By enabling and logging in a root you are the System and have privileges to edit system files. With option 2 since you are not the System, you must edit the file in a non System folder. After placing the file back in a System folder you have to run the above Terminal commands to change the ownership of the file back to the System. Otherwise the System will ignore the file it has no privileges to and create a new default com.apple.boot.plist file. *Note: As I recall, to input these entries your Administrator account must have a password. Terminal will not accept a blank password. You must also be logged on as an administrator.

Will not boot into 64bit, even if I edit the plist. 64bit Windows 7 works perfectly (ish, given how flaky the 64bit bootcamp stuff is) so it's perfectly capable. 17″ Macbook Pro.

The machine reports "EFI64" but whatever I do, I can't get it to boot into 64-bit mode. Tried "6" & "4", tried changing the plist. No go. Any ideas? MacBookPro 3,1.
