Hi, I'm on a MacBook Air 2.13GHz/128GB SSD. I just have a few questions regarding the 64-bit Snow Leopard First off, would a 64-bit kernel benefit me, particularly with my system with fixed memory? I've just realized that most of my core operating system processes run in 64-bit even if I am running in a 32-bit kernel. I don't quite understand how that would affect my performance. Should I force all my apps to run in 32-bit mode? And if so, how would I go about doing that? Thanks everyone.
