Apple released macOS Big Sur on Thursday. It’s a really nice upgrade, but I advise most people to not install it right away. Wait a few weeks or even a few months. But what if you missed upgrading to macOS Catalina, last year’s upgrade? Don’t worry, Apple still offers it for download, you just can’t search for it on the Mac App Store. Apple provides links to download many prior versions of macOS:

Just keep in mind, Apple only releases security patches for the most recent OS plus the two prior which means the following OSes are secure through:
- macOS 11Big Sur: 2023
- macOS 10.15 Catalina: 2022
- macOS 10.14 Mojave: 2021
- macOS 10.13 High Sierra: 2020
- macOS 10.12 Sierra: 2019
- OS X 10.11 El Capitan: 2018
- OS X 10.10 Yosemite: 2017
