View Full Version : Does the new Air run a 64-bit kernel?

Hi folks,

The previous generation MacBook Air would refuse to boot the 64-bit kernel under Snow Leopard. Just wondering if someone could run uname -a in the terminal and find out if the newest generation boots into the 64 bit kernel? If it does then the end of the resulting text will be x86_64, otherwise it will be i386

Yes, Lion defaults to a 64-bit kernel on all Macs.
