osx: installer should copy and launch tuntap driver
I'm thinking about using homebrew, or better, homebrew-cask https://github.com/caskroom/homebrew-cask/tree/master/doc
it's been reported than the regular homebrew drivers won't work on yosemite:
14:02 < ivanalejandro0> ➜ brew install tuntap 14:02 < ivanalejandro0> tuntap: Building this formula from source isn't possible due to OS X 14:02 < ivanalejandro0> Yosemite and above's strict unsigned kext ban. 14:02 < ivanalejandro0> You can install with Homebrew Cask: 14:02 < ivanalejandro0> brew install Caskroom/cask/tuntap 14:02 < ivanalejandro0> You can download from: 14:02 < ivanalejandro0> http://sourceforge.net/projects/tuntaposx/files/tuntap/
