17\b \cf0 **NEW**
18\b0 For Python 3.6, the python.org website now provides only one installer variant for download: one that installs a
19\i 64-bit/32-bit Intel
20\i0 Python capable of running on
21\i Mac OS X 10.6 (Snow Leopard)
22\i0 or later. This ReadMe was installed with the
23\i $MACOSX_DEPLOYMENT_TARGET
24\i0 variant. By default, Python will automatically run in 64-bit mode if your system supports it. The Python installed by this installer is built with private copies of some third-party libraries not included with or newer than those in OS X itself. The list of these libraries is included at the end of the License.rtf file.

33\b \cf0 **NEW**
34\b0 This variant of Python 3.6 now includes its own private copy of OpenSSL 1.0.2. Unlike previous releases, the deprecated Apple-supplied OpenSSL libraries are no longer used. This also means that the trust certificates in system and user keychains managed by the
35\i Keychain Access
36\i0 application and the
37\i security
38\i0 command line utility are no longer used as defaults by the Python
39\f1 ssl
40\f0 module. For 3.6.0, a sample command script is included in
41\f1 /Applications/Python 3.6
42\f0 to install a curated bundle of default root certificates from the third-party
43\f1 certifi
44\f0 package ({\field{\*\fldinst{HYPERLINK "https://pypi.python.org/pypi/certifi"}}{\fldrslt https://pypi.python.org/pypi/certifi}}). If you choose to use
45\f1 certifi
46\f0 , you should consider subscribing to the{\field{\*\fldinst{HYPERLINK "https://certifi.io/en/latest/"}}{\fldrslt project's email update service}} to be notified when the certificate bundle is updated.\
47\
48The bundled
49\f1 pip
50\f0 included with the Python 3.6 installer has its own default certificate store for verifying download connections.\

55\b0 \ulnone \
56\
57To use IDLE or other programs that use the Tkinter graphical user interface toolkit, you need to install a newer third-party version of the
58\i Tcl/Tk
59\i0 frameworks. Visit {\field{\*\fldinst{HYPERLINK "https://www.python.org/download/mac/tcltk/"}}{\fldrslt https://www.python.org/download/mac/tcltk/}} for current information about supported and recommended versions of
60\i Tcl/Tk
61\i0 for this version of Python and of Mac OS X. For the initial release of Python 3.6, the installer is still linked with Tcl/Tk 8.5.\
