If you haven’t seen the alert above for months, and you are confident that you can survive in an exclusively 64-bit world, upgrade to Catalina as you see fit (making sure to have a good backup with Time Machine, or a image of your Mac with a app like SuperDuper or Carbon Copy Cloner). The team at CodeWeavers have written a great article here explaining their current progress, and the challenges that lie ahead before a solution will be available. It also presents a few challenges for those using virtual machines or emulators ( Parallels, VMware Fusion, Wine/Crossover). This has some wide-ranging implications: applications that have been giving you that annoying pop-up about your app not being optimized for your Mac will go away and you quite simply won’t be able run that application. However, there are also some significant changes coming, including the end of 32-bit applications, and support for 32-bit applications. There are plenty of new features and enhancements included in Catalina for more information, check out Apple page: While there is still no official release date for Catalina, macOS 10.15 is coming soon.
