Visit https://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. |

| Ned Deily | af62790 | 2014-11-14 18:57:13 -0800 | [diff] [blame^] | 14 | As of Python 2.7.9, installer packages from python.org are now compatible with the Gatekeeper security feature introduced in OS X 10.8. Downloaded packages can now be directly installed by double-clicking with the default system security settings. Python.org installer packages for OS X are signed with the Developer ID of the builder, as identified on the download page for this release (https://www.python.org/downloads/). To inspect the digital signature of the package, click on the lock icon in the upper right corner of the Install Python installer window. Refer to Apple’s support pages for more information on Gatekeeper (http://support.apple.com/kb/ht5290). |

| Ned Deily | af62790 | 2014-11-14 18:57:13 -0800 | [diff] [blame^] | 21 | With the change to the newer flat format installer package, the download file now has a .pkg extension as it is no longer necessary to embed the installer within a disk image (.dmg) container. If you download the Python installer through a web browser, the OS X installer application may open automatically to allow you to perform the install. If your browser settings do not allow automatic open, double click on the downloaded installer file. |

| Ned Deily | af62790 | 2014-11-14 18:57:13 -0800 | [diff] [blame^] | 28 | The Python installer now includes an option to automatically install or upgrade pip, a tool for installing and managing Python packages. This option is enabled by default and no Internet access is required. If you do not want the installer to do this, select the Customize option at the Installation Type step and uncheck the Install or ugprade pip option. |

| 31 | Binary installer support for OS X 10.4 and 10.3.9 discontinued |
| 32 | [CHANGED for Python 2.7.9] |
| 33 | ============================= |
| Ned Deily | e1c979495 | 2013-01-29 00:07:46 -0800 | [diff] [blame] | 34 | |
| Ned Deily | af62790 | 2014-11-14 18:57:13 -0800 | [diff] [blame^] | 35 | As previously announced, binary installers for Python 2.7.9 from python.org |
| 36 | no longer support Mac OS X 10.3.9 (Panther) and 10.4.x (Tiger) systems. |
| 37 | These systems were last updated by Apple in 2005 and 2007. As of 2.7.9, the |
| 38 | 32-bit-only installer supports PPC and Intel Macs running OS X 10.5 (Leopard). |
| 39 | 10.5 was the last OS X release for PPC machines (G4 and G5). The 64-/32-bit |
| 40 | installer configuration remains unchanged and should normally be used on OS X |
| 41 | 10.6 (Snow Leopard) and later systems. This aligns Python 2.7.x installer |
| 42 | configurations with those currently provided with Python 3.x. If needed, |
| 43 | it is still possible to build Python from source for 10.3.9 and 10.4. |

| 50 | will not conflict. Python 2 command names contain a 2 or no digit: python2 (or |
| 51 | python2.7 or python), idle2 (or idle2.7 or idle), pip2 (or pip2.7 or pip), etc. |
| 52 | Command names for Python 3 contain a 3 in them: python3, idle3, pip3, etc. |
