El Capitan update: Ruby, Rails, homebrew, VirtualBox/Vagrant, Elixir etc.
My notes from updating to El Capitan, as a Ruby/Rails developer working in VirtualBox/Vagrant.
Our dev environment currently requires us to use older versions of VirtualBox (4.3) and Vagrant (1.7.1).
It seems the new "SIP" protection messes with that version of VirtualBox.
I tried upgrading VirtualBox (to 5.0.6) and Vagrant (to 1.7.4). Those seemed to run fine on El Capitan, but we rely on Chef v. 10 and Vagrant doesn't seem to get along with it (error: "invalid option: --force-formatter").
