There are mixed reports that the first release of MacOS Catalina 10.15 has some bugs which can impact various users to varying extents, with issues impacting things that worked fine with prior macOS versions. While many users report MacOS Catalina works great for them, there are others who report the initial macOS 10.15 release is still fairly buggy. If you aren’t sure whether or not a particular app will ever become 64-bit, your best bet is likely to contact the developer of that application directly, and inquire with them. You can find all 32-bit apps on a Mac in System Information tool as shown here if you aren’t sure. If you have any mission critical apps that are 32-bit, you’ll likely want to hold off on MacOS Catalina until those critical apps are updated to be 64-bit, or until you find a replacement app for them. 1: Waiting Until Critical Apps Updated to 64-bit So what are the options? Let’s review some of the choices available, but ultimately it will be every users own decision to make on whether or not to update to MacOS Catalina now, later, or never at all. But MacOS Catalina is different in that it no longer has support for 32-bit apps, and no longer has iTunes (instead it’s replaced by a series of apps to serve the same purpose), and those changes are different from other recent MacOS software updates. With every major new MacOS update, some users end up wondering if they should bother updating to the latest version of MacOS or not, and MacOS Catalina 10.15 is no different in that regard. If you’re not sure whether or not you should install MacOS Catalina, or you’re thinking of holding off on MacOS Catalina for a while, or even ignoring it entirely, we’ll discuss those ideas and present some alternatives here.
