Ok so I open terminal and run this command:
ioreg -l -p IODeviceTree | grep firmware-abi
and get this output:
| | "firmware-abi" = <"EFI32">
So I edit my com.apple.boot.plist file and tell it to boot in 64bit mode:
then I run terminal again but still get the<"EFI32"> output.
Then I go to system profile and it shows this under System Software Overview:
System Version: Mac OS X 10.6.2 (10C540)
Kernel Version: Darwin 10.2.0
Boot Volume: SNOW
Boot Mode: Normal
Computer Name:My Mac Pro
User Name: username
Secure Virtual Memory: Not Enabled
64-bit Kernel and Extensions: Yes
Time since boot: 16 minutes
So which is it?!?! 32bit mode or 64bit mode?!?! It seems to running snappier than Leopard.
Can someone shed some light on this?
