And Python 4.x will be out soon, but it will be completely backward compatible. The entire Python community has now moved on to using Python 3.x (the current version as of writing this is 3.9). But it's Python Version 2.7, which is now deprecated (abandoned by the Python developer community). So far I am enjoying my BigSur experience.MacOS comes with Python pre-installed. Special thanks to v for this post in dev.to and to Ernest Ojeh for this post pre- 2.60 homebrew, and of course to all the folks at Apple and Homebrew.

Python, Anaconda, Homebrew, Git & GitHub, my antivirus software, among others.

Pay attention to what the developers of your most frequently used tools say about a new big release.

However, I wanted to add some content to my website, and that is where I hit the jackpot. When I finally updated to BigSur, I was happy that I delayed my update because Sophos, Anaconda, and Git were all working correctly. I knew I would have to fix several things in my development environment, so I backed up my computer to an external drive just in case I needed to revert to my previous OS for any reason. However, it is finally winter break, and it was time to update to the newest OS.

So when Apple rolled out its latest macOS (BigSur) back in November 2020, I decided to wait, especially since the University of Arizona warned its employees that there might be some compatibility issues regarding Sophos security software (which I use). When a new version of an operating system comes out, I usually don’t install it right away unless it’s absolutely necessary.
