Installing CubicSDR using Homebrew

Run brew tap dholm/homebrew-sdr followed by brew install cubicsdr --HEAD. Assuming your Homebrew prefix is in your path you should be able to launch CubicSDR simply by running CubicSDR from a terminal.

To upgrade CubicSDR, since it is a head-only formula, simply remove it and then install it again.
