This package will install Python $FULL_VERSION for Mac OS X

Installing on OS X 10.8 (Mountain Lion) or later systems
|
|
========================================================
|
|
|
|
If you are attempting to install on an OS X 10.8+ system, you may
|
|
see a message that Python can't be installed because it is from an
|
|
unidentified developer. This is because this Python installer
|
|
package is not yet compatible with the Gatekeeper security feature
|
|
introduced in OS X 10.8. To allow Python to be installed, you
|
|
can override the Gatekeeper policy for this install. In the Finder,
|
|
instead of double-clicking, control-click or right click the "Python"
|
|
installer package icon. Then select "Open using ... Installer" from
|
|
the contextual menu that appears.
|
|
|
|
**** IMPORTANT changes if you use IDLE and Tkinter ****
|
|
|
|
Installing a third-party version of Tcl/Tk is no longer required
|
|
================================================================
|
|
|
|
Beginning with Python 3.4 alpha2, the 10.6+ 64-bit installer now
|
|
comes with its own private copy of Tcl and Tk 8.5 libraries. For
|
|
this version of Python, it is no longer necessary to install
|
|
a third-party version of Tcl/Tk 8.5, such as those from ActiveState,
|
|
to work around the problematic versions of Tcl/Tk 8.5 shipped by
|
|
Apple in OS X 10.6 and later. (This does not change the requirements
|
|
for older versions of Python installed from python.org.) By default,
|
|
this version of Python will always use its own private version,
|
|
regardless of whether a third-party Tcl/Tk is installed.
|
|
The 10.5+ 32-bit-only installer continues to use Tcl/Tk 8.4,
|
|
either a third-party or system-supplied version.
|
|
Since this is a new feature, it should be considered somewhat
|
|
experimental and subject to change prior to the final release of
|
|
Python 3.4. Please report any problems found to the Python bug
|
|
tracker at http://bugs.python.org.
|
|
|
|
Visit http://www.python.org/download/mac/tcltk/
|
|
for current information about supported and recommended versions of
|
|
Tcl/Tk for this version of Python and of Mac OS X.
|
|
|
|
Using this version of Python on OS X
|
|
====================================
|
|
|
|
Python consists of the Python programming language interpreter, plus
|
|
a set of programs to allow easy access to it for Mac users including
|
|
an integrated development environment, IDLE, plus a set of pre-built
|
|
extension modules that open up specific Macintosh technologies to
|
|
Python programs.
|
|
|
|
The installer puts applications, an "Update Shell Profile" command,
|
|
and a link to the optionally installed Python Documentation into the
|
|
"Python $VERSION" subfolder of the system Applications folder,
|
|
and puts the underlying machinery into the folder
|
|
$PYTHONFRAMEWORKINSTALLDIR. It can
|
|
optionally place links to the command-line tools in /usr/local/bin as
|
|
well. Double-click on the "Update Shell Profile" command to add the
|
|
"bin" directory inside the framework to your shell's search path.
|
|
|
|
You must install onto your current boot disk, even though the
|
|
installer may not enforce this, otherwise things will not work.
|
|
|
|
You can verify the integrity of the disk image file containing the
|
|
installer package and this ReadMe file by comparing its md5 checksum
|
|
and size with the values published on the release page linked at
|
|
http://www.python.org/download/
|
|
|
|
Installation requires approximately $INSTALL_SIZE MB of disk space,
|
|
ignore the message that it will take zero bytes.
