Snow Leopard: 32vs 64 bit kernel install

[kris2999]

Hey,

Just wondering what the thoughts everybody was having regarding loading Snow Leopard with a 32bit kernel (i.e. "normal" install) or 64 bit kernel (i.e. holding down the "6" and "4" keys during reboot).

Should be getting my copy in the mail today/tomorrow and wondering which was the best way to go?


Cheers,
Kris

Best way is: just install and dont worry about 32/64bit...

All apps, as I understand it can be run in 64 bit even though your not running the 64-bit kernel, I've come to understand that you only need the 64-bit kernel if you have over 32 gig RAM.

This story about the 32 and 64-bit kernels was the worse possible piece of news that could have leaked.

Just use Snow Leopard as it is and forget about that silly business. Snow Leopard represent the insane advantage Apple has over Windows right now. They can release an OS that plants the seeds for future development and removes old and useless code.

There is a reason why the kernel hasn't gone 64-bit yet, and you are not going to get anything from booting in the 64-bit kernel. Let it be and let developers get to work. Then when everything is in place, you'll see that Apple turns the switch on the kernel.

I booted into the 6 4 and Dahmmmmm

noticeably faster. Fusion will not work though. Needs to be 32 bit so the pop up says.

I have a mid-2009 15 MBP 2.53 GHz.

also, my usb verizon air card only works in 32 bit mode.

I'm gonna say it again, this thing is way faster, noticeably faster when I boot into 64 bit mode. WOW

I wonder if that is only because some things didn't load since they are only 32bit?

Cheers for that.

Indeed, as VMware and Parallels cannot run when 64 bit kernel is active, I set the default to 32 bits (aka.... do nothing) on my Mac Pro '08, Radeon HD 4870.
