iPad apps are coming to the Mac, and iTunes is being broken apart into several different apps. From a consumer perspective, those are the most significant new aspects of macOS Catalina, which Apple will roll out to Mac computers this fall. Today, the company is releasing its first public beta of Catalina. Let me say this up front: you should only install the beta on a secondary Mac you’ve got around the house; it’s been fairly stable in my testing, but it’s by no means ready to be put on your full-time laptop, iMac, or Mac mini.
