  Support for Multiple TeX Distributions
New versions of TeX Live are produced approximately once a year. The previous version of MacTeX contained TeX Live 2016; the new version contains TeX Live 2017. Installing the new version preserves the old version, and it is easy to switch back to that version if the new TeX Live has a bug. To understand how that is accomplished, read the document on support for Multiple TeX Distributions.

Uninstalling MacTeX
