10.6: How to boot into the 64-bit kernel
Authored by: macgruder on Sep 16, '09 01:35:49AM

This is an interesting hint. People who are not really really sure of its implications should ignore it though :-)

Whether you boot into the 64-bit <b>kernel</b> or not, your 64-bit <b>apps</b> and libraries will still run in 64-bit.

So stick with the 32-bit kernel unless you are sure that all of your kexts are fine with the 64-bit kernel, and you need massive amounts of memory - dozens of gigs.

The only other reason for booting into the 64-bit kernel that I can think of is if you are the kind of person who enjoys saying my **** is bigger than yours :-)

Again,

Because of the Intel architecture, 64-bit processes gain access to more registers and will experience a speed increase.

Yes, but all users will get this speed increase for their 64-bit apps whether or not they boot into the 64-bit kernel. For the vast majority of users the kernel running in 64-bit will not make a noticeable difference - but they may well run into compatibility problems.
