Thanks to Dion for pointing out how to get your MacBook to hibernate! When I wrote about switching to the MacBook Pro one of my complaints was that upon shutting the lid the laptop doesn’t hibernate, it sleeps, and they offer you no easy way to switch it via the GUI.
I don’t mind waiting a for my laptop to start when I open the lid and the little white sleeping light drives me nuts, especially if I forget and leave it in our bedroom before going to bed. That sucker lights up the room at night!
So I added the two aliases that Dion suggest, sourced my bashrc, ran hibernateon, shut the lid, and off goes the light… amen!
alias hibernateoff='sudo pmset -a hibernatemode 0'
