Ruby 2.6 on OSX 10.11+ via Homebrew

OLDER VERSION (e.g. 2.0 or less) has issues with expired certificates, and GEMS stop working. GEM INSTALL XXXXX cannot connect.

Quick & Dirty solution – if you do not depend on a specific version of Ruby:


1
brew install ruby

*If homebrew is not installed, read THIS

DON’T FORGET TO UPDATE YOUR PATHS IN .bash_profile
