I started at a new client in Portland today and they gave me a 13" MacBook Pro. This is the first time I've actually used a Mac for a significant amount of time. I'm coming from using Linux machines exclusively for 5+ years, so it's a bit of a departure for me. I'm struggling most with keyboard shortcuts and missing keys. I use keys like, home, end, page up, and page down quite a bit and this keyboard has none of them. I've had to adapt to using two or three key combos to replicate what a normal keyboard does with a single keypress.
I installed homebrew and cask, which is fairly similar to a *nix package manager and seems to work well enough.
After using this for a few days it will probably be awful to go back to one of my Xubuntu machines.
