What should i use with Lion? 64-bit or 32-bit kernel extension?
Whatever your heart desires.
Lion only supports 64 bit. If you're running Lion, you're running the 64bit kernel
I am confused if Lion only runs a 64bit kernel
system info for my mac on lion says
64-bit Kernel and Extensions: No
This is incorrect. My Mac Pro (Early 2008 model) ran with a 32-bit kernel by default.
your computer can only support 3GB of RAM, so 64-bit support doesn't do squat anyway.
But it's faster, right?
(please get the sarcasm and don't drop a diatribe on me thanks)
Some benchmark show that 64-bit kernel is actually faster than the 32-bit kernel with Snow Leopard.
Not sure if this is true in Lion though.
You'd need at least 8GB memory and a crisp eye on fractional gains for this to be true. On Lion it most likely is faster as they spent more time developing in 64-bit kernel rather than 32-bit kernel. I know 64-bit kernel drains my battery more Rest is placebo.
I run Lion on a 2008 MacBook, and it's using a 32-bit kernel.
