Cannot boot Snow Leopard into 64-bit mode

[celticpride678]

I installed Snow Leopard last night and since, I have been trying to boot it into 64-bit mode. I have tried holding down the "6" and "4" keys at startup, but that did not work. Any ideas? Thanks.

Are you sure your Mac is on the capable list?

MacBooks have problems booting into 64-bit kernel. IMO there's no reason to boot 64-bit because it won't make it faster

I read that it is. It is running the EFI-64-bit firmware.

I have heard of it being the same, but wanted to try it out myself.

You may want to download an utility such as this one...

If it works, you can download this one if you want (I personnaly prefer preference panes to apps...).

They're both free, so enjoy

I would echo the responses from others, unless you are 100% certain that your Mac is fully able to run everything hardware and software wise in 64 bit, I would advise you just use 32 bit mode for compatibility purposes and the fact that you won’t really gain anything as an end user performance wise. 64-bit programs work just fine in 32 bit mode.
