That's why a large portion of users still prefer Catalina even if their device is compatible with Big Sur. Probably the most important change is the deprecation of iTunes into three separate entities for Music, TV, and Podcasts. The same is true of Catalina as well, but Catalina is a more mature version and brings a lot of features to the table, such as the improved Siri, customizable smart lists, the new AI-based Photos app, better Notes search, refreshed Safari, and so on. You have to upgrade macOS to Catalina in such a case if the app is very important for you. You will receive the following messages if you try to run an app that only supports Catalina and later versions. But there's also another reason: Big Sur is only meant for certain models of MacBooks and iMacs.Īnd some of the apps can not work on an old version of macOS, such as High Serria or Serria. Not all Mac users will install Big Sur so soon after its release because they'll be waiting for all the major bugs to be fixed in an 11.x update. MacOS Catalina is the last iteration of the macOS series, after which Apple has now moved to macOS 11 Big Sur.
