10If you are attempting to install on an OS X 10.8+ system, you may
Ned Deilye1c9794952013-01-29 00:07:46 -080011see a message that Python can't be installed because it is from an
12unidentified developer. This is because this Python installer
13package is not yet compatible with the Gatekeeper security feature
14introduced in OS X 10.8. To allow Python to be installed, you
15can override the Gatekeeper policy for this install. In the Finder,
16instead of double-clicking, control-click or right click the "Python"
17installer package icon. Then select "Open using ... Installer" from
18the contextual menu that appears.

22Installing a third-party version of Tcl/Tk is no longer required
23================================================================
24
25As of Python 2.7.6, the 10.6+ 64-bit installer now
26comes with its own private copy of Tcl and Tk 8.5 libraries. For
27this version of Python, it is no longer necessary to install
28a third-party version of Tcl/Tk 8.5, such as those from ActiveState,
29to work around the problematic versions of Tcl/Tk 8.5 shipped by
30Apple in OS X 10.6 and later. (This does not change the requirements
31for older versions of Python installed from python.org.) By default,
32this version of Python will always use its own private version,
33regardless of whether a third-party Tcl/Tk is installed.
34The 10.3+ 32-bit-only installer continues to use Tcl/Tk 8.4,
35either a third-party or system-supplied version.

Ned Deily2a6f4b32011-01-30 00:18:47 +000044Python consists of the Python programming language interpreter, plus
45a set of programs to allow easy access to it for Mac users including
46an integrated development environment, IDLE, plus a set of pre-built
47extension modules that open up specific Macintosh technologies to
48Python programs.

Ned Deily2a6f4b32011-01-30 00:18:47 +000050The installer puts applications, an "Update Shell Profile" command,
Ned Deilye1c9794952013-01-29 00:07:46 -080051and a link to the optionally installed Python Documentation into the
Ned Deily2a6f4b32011-01-30 00:18:47 +000052"Python $VERSION" subfolder of the system Applications folder,
53and puts the underlying machinery into the folder
54$PYTHONFRAMEWORKINSTALLDIR. It can
55optionally place links to the command-line tools in /usr/local/bin as
56well. Double-click on the "Update Shell Profile" command to add the
57"bin" directory inside the framework to your shell's search path.

Ned Deilye1c9794952013-01-29 00:07:46 -080059You must install onto your current boot disk, even though the
Ned Deily0203a802013-10-25 00:40:07 -070060installer may not enforce this, otherwise things will not work.
Ned Deilye1c9794952013-01-29 00:07:46 -080061
62You can verify the integrity of the disk image file containing the
63installer package and this ReadMe file by comparing its md5 checksum
64and size with the values published on the release page linked at
65http://www.python.org/download/
66
Ned Deily0203a802013-10-25 00:40:07 -070067Installation requires approximately $INSTALL_SIZE MB of disk space,
68ignore the message that it will take zero bytes.
