If you are running on macOS 10.9 or later and if you have no need for compatibility with older systems, use the 10.9 variant.  Use the 10.6 variant if you are running on macOS 10.6 through 10.8, if you need to maintain compatibility with previous 3.6.x releases, or if you want to produce standalone applications that can run on systems from 10.6.  The Pythons installed by these installers are built with private copies of some third-party libraries not included with or newer than those in macOS itself.  The list of these libraries varies by installer variant and is included at the end of the License.rtf file.\
