The rumour has it that apps will be compatible between MacOS and iOS. Does that mean that we will run Mac app on iOS ? It could make sense but the apps have to be develuthat way. I’m pretty sure that there could be a way to port the older MacOS apps to iOS....the problem would be touch input.
Touch could be the mouse. Double tap/long press could right click. Otherwise, I suspect not everything may translate smoothly. May want to look into how Chromebooks can now run Android apps, as that similar to what's going to go on for here as well, and could provide some insight.
