Title says it all.
I cannot find any confirmation on whether the MacBooks will run Snow Leopard in full 64 bit mode.

Anyone?

Every generation of MacBooks since the original Core 2 Duo will be able to run it in 64 bit mode.

Not in the current build (there are no Macbooks on the list). I don't think there has been any official word on what machines will be enabled.

It has a C2D. It can do it. If Apple hampers it Snow Leopard will be hacked to work with them.

I'm not arguing. Snow Leopard is still in the beta stage and IMHO has quite a way to go yet. It's just not currently supported, that's all.

Like Jim Carey would say:


YES

The build previous to that one didn't have support for any portable.

SL will have 64-bit support for almost all Intel C2D and up.

Isn't the whole point of 64-bit accessing larger amounts of RAM? So, with most macbooks shipping with 2GB and all maxing out at 4GB, isn't a 64 bit macbook not worthwhile, even if the processor is capable? Would there be any benefit to macbook owners?

64 bit doesn't mean more RAM, it means more address space for each individual process. You can have 32 GB of RAM and use ten 32-bit applications using 3 GB each and have some spare RAM. With 64 bit, a video editing application running on a machine with 1 GB of RAM can map a 2 hour video in MiniDV format = about 21 GB completely into virtual memory and let you edit it.

In addition, 64 bit means sixteen 64-bit integer registers instead of eight 32-bit integer registers, which makes some applications a lot faster, even when they don't use much memory at all.

+1. It opens up the world of 64-bit arithmetic. Question is, which apps will use it?

Almost all Apple apps will be utilizing the 64 bitness come October. It's up to the other companies like Adobe and Microsoft to come up with the other software.

I know that the C2D processor is 64 bit. But at the time the newest MacBook was released, there were some news about the NVIDIA graphics chip not being "64 bit". That and the fact that no Snow Leopard build supports the MacBook in 64 bit mode yet looks suspicious to me.

Could it be possible that Apple will support the MacBook in 32 bit mode and the MacBook Pro in 64 bit mode in SL? As a way to differentiate the pro from the consumer machines (same as omitting the FireWire port)?

the macbooks use the same chipset as the macbook pros dont they? its just that the macbook pro has an extra graphics processor. Apple wouldnt disable 64bit on a machine so new, that would make many people angry. Very angry.

Lets hope that Rambo doenst have a macbook, cause we dont want him angry do we?

Our graphics cards are not "64-bit" or "32-bit" items. Besides, we have a 128-bit bandwidth (excluding 9400M).

Exactly what I said. SL has a long way to go before it is released. Making any kind of guesses at this point is fruitless.

But I want to know whether it is safe to buy a MacBook today. I would be pissed if it were not supported in 64 bit mode in SL.

That's what this forum is about, otherwise I would have asked this question on Apple Discussions.

Don't get us wrong, we're not being rude.
We just don't know that answer since no one has info on that as of right now.
But personally I don't see why a MB wouldn't run it ok, especially if we consider that Apple is making an OS that's supposed to be more responsive and take advantage of multi core processors instead of adding lots of new features.
I'd say it will run even smother than Leopard is running right now, but take that just as a personal guess

Of course. My two year old Macbook will run it. I'm pretty sure all Intel machines will run it.

Yes a UniBody MacBook will run Snow Leopard.

If you don't believe us, go ask Steve.

will support up to 6 Gigs of ram by using one 2 gig stick and one 4 gig stick with using Leopard. I imagine when using SL 8 gigs will work fine though.

I think it's been figured out that the RAM limitation is not in software, but in firmware/hardware with the MB vs MBP--> artificial differentiation between "consumer" and "pro" lines.

fwiw the issue is more subtle than many here would think, and nobody has yet touched on what the actual requirement is. That said, I don't think there's any reason to care about this particular distinction* (yet. It'll matter for future hardware).


(sorry for vagueness, NDA)


*and I'm not referring to running 64 bit apps here. Any C2D should be able to do that fine.

I was unsure whether the core2duo in the aluminium macbooks are 64-bit,

call me a little naive or n00b but ive just switched to a mac,

does this mean the macbook aluminium 2.0ghz has a 64-bit core2duo?

thanks in advance.

If it's Core2Duo, it's 64bit architecture.

how cool is that! two weeks after having this fantastic new machine, i find out its got a 64-bit processor to boot!! :)

Not necessarily, we're still waiting on a 64-bit version of Safari to run Java 6 applets. How long have we been waiting? Oh, only since October 26, 2007.
