Default noob here, lost at rooting

hey all,

I'm a complete noob when it comes to rooting

I've been searching online on how to root a nexus 4 using a mac.. every single guide is different, some skip the unlocking bootloader part, some skip other parts, and most guides are just outdated.

I'm running on absolute stock, 4.4.2.

What's the best (and most current) guide out there? I'm interested in rooting my phone mainly so I can get LTE access.. do no care too much for non stock ROMS (not yet at least)
