New Macbook Booting to 64Bit

[ncfuser]

Just got a the New 2.26GHz Intel Core 2 Duo Unibody Mackbook on Saturday.
I was just checking things out and I found out that it was in 64-bit mode.

Its right out fo the box, I never checked anything nor am I holding down the 6 and the 4 while booting.

Is this now standard for it to boot in 64 bit out of the box?

Thanks

Are your applications running in 64-bit or in the actual kernel and extensions running in 64-bit? To tell this, go to the System Profiler>Select "Software". Then, look at "64-bit Kernel and Extensions"- YES (true 64-bit), NO (applications).

Another way to check is to go to your activity monitor and see if the kernel is listed as Intel or Intel (64-bit).

All apps can run in the 64-bit space despite the kernel being 32-bit, so yeah...

Perhaps though they enabled 64-bit kernel support on the newest white unibody MacBooks *shrug*

is there and added benefit to running in 64 as to 32?

States No.

Got you.
I was missing reading on how to check.
I thought this was telling me I was in 64 mode:
ioreg -l -p IODeviceTree | grep firmware-abi

But only tells me I "can" boot in 64.

Sorry.

On a MacBook? No.

Basically no. There's a theoretical performance advantage, but I've never been able to measure it, even with fairly powerful analysis tools and benchmark apps that I wrote specifically to show it. It's primarily useful for very large memory systems (i.e. not a macbook).

It might help VMWare performance a bit. I haven't checked that.
