On the newer macOS Catalina, you’ll see a similar pop-up box stating your app “needs to be updated.” But after upgrading to Catalina, apps that prompt this error will not run at all. The issue has to do with Apple’s transition from 32-bit to 64-bit apps.
64-bit apps are more capable than their 32-bit counterparts because they can take better advantage of more powerful 64-bit multi-core processors, tap into larger amounts of RAM and more. “These apps can access dramatically more memory, enable faster system performance, and take advantage of technologies that define today’s Mac experience, such as Metal graphics acceleration,” Apple says in a support page explaining the transition.

What’s that mean for you? For one, if you’re dependent on a particular 32-bit app, it won’t work in macOS Catalina, as many Twitter users discovered after upgrading. Meanwhile, some popular apps, like Adobe Photoshop, appear to be suffering from temporary compatibility issues with Catalina, so it’s best to hold off on upgrading until a software patch resolves those problems.
