Now the theory behind this whole thing is that iPad developers will be able to check a single box in Xcode and then magically that application will be ready to go in Mac OS in reality it doesn’t work that easily but there is a nice handful of applications that are already available and there will no doubt be many more coming down the pipeline. Some of the top changes and features to Mac OS Catalina I think you’ll agree is catalyst apps and these are applications previously iPad apps that have been migrated over to Mac OS.
