hi i bought my macbook 13 inch 2.0 core 2 duo one's about 4 month before they refreshed the line and expanded the ram and slapped pro behind it. now am hearing about the whole snow leopard not running in 64 bit at boot up on the macbooks. i know that the chip is design for 64 bit os'es and i know that the hack with 6 and the 4 key won't work on my computer. but am wondering if the macbook line will ever be able to run mac os x in 64 bit. i mean isn't 4 gb or ram the minimum you need . i know that's how it was on window 7 to run it in 64 bit. i was just thinking now i know why they upgraded the macbook line right before snow leopard. one thing i have noticed is that all the apps that are wrote for 64 bit load much quicker then 32 bit apps.so that got me thinking if apple will ever let snow leopard or above run in 64-bit on the non pro macbook? and if it could be done though an upgrade though software update or though the operating system ? what are you guys/girls thoughts on it?
Got a tip for us?

Will macbooks the 13 inch aluminum one ever be able to run in 64-bit?

Unless your macbook is going to have more than 4GB RAM, you really don't need to worry about the whole 64bit thing, seriously, just have fun with your macbook and stop worrying about little petty things.
I'm pretty sure he knows that he can run 64-bit apps on a 32-bit kernel. Thats not really what hes asking though.
As for me, i'm not sure, it definitely has the hardware but it is up to apple to decide.

Are you so sure, no offense to the OP but people seemed so wrapped up about 32bit vs. 64bit with many of them not realizing that SL is 64bit
If you want to run K64 it IS possible on a MacBook. I am running it on my whitebook now...

or just press the 6 and 4 keys on boot up, although there is no point, as maflynn said, SL is already 64bit, regardless of whether or not the kernel is 32 or 64 bit, all other apps can be either regardless of the kernelIf you want to run K64 it IS possible on a MacBook.

Right, as I understand it, only the Macs in this chart...

Can boot into 64-bit kernel without modification. So if I understand right, even the MBP13" is out, even though it can be upgraded to 8GB of memory? I mean, all debate of whether there is any point in doing this aside, I'm not sure there's any more point in doing it on a 15" MBP with 8GB of memory than on a 13" MBP with 8GB of memory...
I REALLY wish somebody would write up a definitive "64 bits and Snow Leopard - What you need to know" and sticky it... This has to be like the 100th thread posted where the OP is confused about 64 bit-ness and what it means with Snow Leopard... If I didn't have 50 other things to get done today, I'd write it up myself...
This is just getting insane!

Quick question, if you hold down "6" and "4" to boot into 64-bit kernel, does that reset once you restart the computer or do you have to press another set of keys to get back to the 32-bit kernel?
I think that should be unless you have more than 32GB RAM. Apple has been selling Macs with dozens of GB RAM for a while now with Leopard's 32Bit kernel.
By using PAE Snow Leopard's 32 bit kernel supports a maximum of 32GB RAM. Considering you won't be able to physically fit more than 32GB in any Mac apart from an Xserve memory constraints are not an issue under de 32Bits kernel.
The 32-bit kernel is limited to supporting 32GB RAM. More than you will ever be able to fit in any of the current laptops. There is a reason the Xserve is the only machine defaulting to the 64bit kernel, it is the only machine that could realistically benefit from supporting more than 32GB RAM at this stage.
You're quite right that there is no point in doing it unless you are developing 64 bit kexts (which being kernel extensions, have to match the kernel). The modification I made to my boot.efi allows me to boot into K64 for that very purpose with the method you described. I still boot into K32 as default.

Just did this on my 13" unibody macbook 5,1 with 4gb of ram. it works. yea. don't see any improvement though. yea.

Could you tell me how you did it? I didn't understand a word of the tutorial, so would be nice to have someone who did it walk you through it. I have the same MacBook as you. And for the tutorial, my SHA sum didn't correspond to the one he had posted...

Check your PM...
WTF KIND OF ANSWER IS THIS, IT'S 5 YEARS LATER I'M SO HAPPY I GOOGLED AND FOUND AN ANSWER AND ALL I GET IS THIS ****.
I believe there's a relevant XKCD for this situation
