| |
| 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 **** |
| |
| Update your version of Tcl/Tk to use IDLE or other Tk applications |
| ================================================================== |
| |
| To use IDLE or other programs that use the Tkinter graphical user |
| interface toolkit, you may need to install a newer third-party version |
| of the Tcl/Tk frameworks. 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. |

| Binary installer support for 10.4 and 10.3.9 to be discontinued |
| =============================================================== |
| |
| Python 2.7.7 is the last release for which binary installers will be |
| released on python.org that support OS X 10.3.9 (Panther) and 10.4.x |
| (Tiger) systems. These systems were last updated by Apple in 2005 |
| and 2007. As of 2.7.8, the 32-bit-only installer will support PPC |
| and Intel Macs running OS X 10.5 (Leopard) and later. 10.5 was the |
| last OS X release for PPC machines (G4 and G5). (The 64-/32-bit |
| installer configuration will remain unchanged.) This aligns Python |
| 2.7.x installer configurations with those currently provided with |
| Python 3.x. Some of the reasons for making this change are: |
| there were significant additions and compatibility improvements to |
| the OS X POSIX system APIs in OS X 10.5 that Python users can now |
| take advantage of; it is increasingly difficult to build and test |
| on obsolete 10.3 and 10.4 systems and with the 10.3 ABI; and it is |
| assumed that most remaining legacy PPC systems have upgraded to 10.5. |
| To ease the transition, for Python 2.7.7 only we are providing three |
| binary installers: (1) the legacy deprecated 32-bit-only 10.3+ |
| PPC/Intel format, (2) the newer 32-bit-only 10.5+ PPC/Intel format, |
| and (3) the current 64-bit/32-bit 10.6+ Intel-only format. While |
| future releases will not provide the deprecated installer, it will |
| still be possible to build Python from source on 10.3.9 and 10.4 |
| systems if needed. |
| |
| 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. |
