These warnings may be difficult for the end-user to understand, mainly being included to aid developers and admins in tracking down applications and scripts that require updating. In addition to the written warning to developers in the macOS release notes, Apple has gone the extra step to display informational messages when users attempt to use deprecated Python 2 runtimes in macOS Monterey. One simply cannot replace the runtime with a newer version and expect everything to ' just work.' The same is even true for the various minor versions of Python 3 that are currently supported in parallel, as evidenced by Python 3.7-3.10 being currently supported (as of this writing) while Python 3.11 is in beta. While Python 3 is the official successor, updating Python code from version 2.x to 3.x is not a trivial undertaking. This means that updates, bug fixes and security updates will only support Python 3.x moving forward, as Python 2 has reached end-of-life. Why the need for this change?Īs of January 2020, the organization that oversees Python development and releases officially sunset Python as of version 2.7 in favor of the newer, more secure Python 3 and subsequent versions. The guidance for developers being to include any runtimes their solutions are dependent on within their apps. Furthermore, Apple stated that scripting runtimes, such as those for Python, Ruby and Perl would no longer be included with future versions of macOS either. And Apple has been warning that the pre-installed Python 2 binary, which has been part of the Mac system since Mac OS X Jaguar 10.2, will be removed in a 'future version of macOS' since the initial beta release notes for macOS Catalina were released. You have Python3 installed on your Mac.Yes.

Now, about Python 3, once Homebrew is installed simply type brew install python3Īnd there we go.

Homebrew will place its 'Cellar' (the set of all the packages you installed with Homebrew) in /usr/local/Cellar. Then install Homebrew by typing ruby -e '$(curl -fsSL )' If you want to give this a try, first of all make sure you have the XCode Command Line Tools installed on your Mac. I personally use Homebrew, which is a very nice package manager.
