Mac Os X Upgrade Python

Posted : admin On 13.08.2021

Installing applications on macOS and OS X computers is easy to do when deploying the apps as packages through the Terminal using the Installer command for quiet deployments across your network. Release Date: Sept. 19, 2017 Python 3.3.x has reached end-of-life. This is its final release. It is a security-fix source-only release. Python 3.3.0 was released on 2012-09-29 and has been in security-fix-only mode since 2014-03-08. 'The basic premise of all Python development is to never use the system Python. You do not want the Mac OS X 'default Python' to be 'python3.' You want to never care about default Python.' How do we stop caring about the default? The first release of the new OS — Mac OS X Server 1.0 — used a modified version of the Mac OS GUI, but all client versions starting with Mac OS X Developer Preview 3 used a new theme known as Aqua. Aqua was a substantial departure from the Mac OS 9 interface, which had evolved with little change from that of the original Macintosh operating.

Release Date: July 20, 2020


This is the fifth maintenance release of Python 3.8

Lnx-update-tools.cmd – retrieves latest OS X guest tools; Mac OS X: On Mac OS X you will need to be either root or use sudo to run the scripts. This is really only needed if you want to use client versions of Mac OS X. You may need to ensure the OS X scripts have execute permissions by running chmod +x against the 2 files.

Note: The release you're looking at is Python 3.8.5, a bugfix release for the legacy 3.8 series. Python 3.9 is now the latest feature release series of Python 3. Get the latest release of 3.9.x here.

3.8.5 has been released out of schedule due to important security content. For details please consult the change log. Please upgrade at your earliest convenience.

Mac Os X Upgrade Python 3

Windows users

  • The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the 'x64' architecture, and formerly known as both 'EM64T' and 'x86-64'.)
  • There are now 'web-based' installers for Windows platforms; the installer will download the needed software components at installation time.
  • There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.

macOS users

  • For Python 3.8, we provide one installer: 64-bit-only that works on macOS 10.9 (Mavericks) and later systems.
  • Please read the 'Important Information' displayed during installation for information about SSL/TLS certificate validation and the running the 'Install Certificates.command'.

Mac Os X Python Version

And now for something completely different

Mac Os X Python Virtualenv

Our universe itself keeps on expanding and expanding,
In all of the directions it can whiz;
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere out in space,
'Cause there's bugger all down here on Earth!

Release Date: Sept. 19, 2017

Python 3.3.x has reached end-of-life. This is its final release.It is a security-fix source-only release.

Python 3.3.0 was released on 2012-09-29 and has been in security-fix-only mode since 2014-03-08. Per Python Development policy, all support for the 3.3 series of releases ended on 2017-09-29, five years after the initial release. This release, Python 3.3.7, was the final release for the 3.3 series.

Mac Os X Upgrade Python

After 2017-09-29, we no longer accept bug reports nor provide fixes of any kind for Python 3.3.x (third-party distributors of Python 3.3.x may choose to offer their own extended support). Because 3.3.x has long been in security-fix mode, 3.3.7 may no longer build correctly on all current operating system releases and some tests may fail. If you are still using Python 3.3.x, we strongly encourage you to upgrade to a more recent, fully supported version of Python 3; see

Python 3.3 includes a range of improvements of the 3.x series, as well as easierporting between 2.x and 3.x.
