| This package will install Python $FULL_VERSION for Mac OS X |
| $MACOSX_DEPLOYMENT_TARGET for the following architecture(s): |
| $ARCHITECTURES. |
| |
| **** IMPORTANT **** |
| |
| 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 |
| ================================================================ |
| |
| As of Python 3.3.3, 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. |
| |
| 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. |
