Upgrading to latest Git & Github tools to latest 2.2.1

gistfile1.man

--------------------------------
 Check Git version:
--------------------------------
git --version

If you don't see one of the following, you should to update:

v1.8.5.6, v1.9.5, v2.0.5, v2.1.4, and v2.2.1, 


Notes: 
1.9.3 - MAC  Apple used to distribute a git client as part of 'developer tools'. It is installed as part XCode and for iOS development. If your terminal is using that mac-version, you will see: 1.9.3 - MAC or some number

If you are using Git Mac-client all-the-time (and never use command line), you should be good using just LATEST GitHub for Windows(https://windows.github.com/) and GitHub for Mac(https://mac.github.com/).  These clients comes with bundled Git + UI so you should be good by simply installing them.
