Learn which apps are 32-bit on your Mac and why that matters.

In this lesson for What’s New in macOS Catalina, I look at how you can tell which apps are 32-bit. Why do we want to do this? 32-bit apps no longer work in macOS Catalina. Note: If you are not using macOS Catalina, this method does not work, you’ll need to see my video demonstrating this with macOS Mojave.
