I recently bought a Macbook Air 13" (2014 model). It is an amazing machine. Apple has done very well with this little laptop/ultrabook/netbook/whatever.

Pros

• Light and very small
• 12+ hours battery life
• Great build quality

Cons

• Mac OS is very restrictive
• No delete key, no home key, strange position of fn key
• Keyboard is not symmetric

Archlinux seemed like the best choice of Linux to put onto the Macbook. Here is the process I follwed.

Create Bootable Flash Drive

Partition

Install Archlinux

EFI Bootloader
