Personally, I voted no because I think iPadOS should remain distinct in certain UI aspects compared to macOS. macOS was designed for cursor/keyboard input, iPadOS was designed for touch-first input. This difference becomes very clear when you connect to a Mac via VNC from an iPad. The system simply isn’t optimized for touch input, and I wouldn’t really want to use macOS on the iPad for the majority of the things that I do. Now, that said, I do think the functionalities of the two softwares could merge. And iPadOS 16 seems to indicate that that is already happening. I think iPadOS should remain a distinct, touch-first OS, but gain more macOS functionality. I wouldn’t necessarily oppose a way of porting mac apps over to the iPad. I actually kind of think the chances of this happening might be pretty good. Apple could create a sort of reverse Catalyst 2.0 that allows developers to readily port their mac apps over to the iPad. I think one thing is for sure, now that both platforms can run the same apps, any new software will probably be written to run on both. It just makes sense. If you’re a software developer and you have the choice of writing one app that can run on two platforms or 2 separate apps, which would you be more likely to pick? Also, with sideloading becoming required on iPadOS, I could see Apple working to make cross-platform App Store apps to unify their systems and strengthen the appeal of the App Store. Maybe Catalyst 2.0 is attached to the new App Store submission system, so the only way to reap the benefits of the system is to publish in the App Store and the system then automatically adjusts the UI of your app for each Apple platform. Apple is already making big strides in this area with Swift Code, so I think that’s not to unlikely. Besides, eventually, even if Apple hasn’t implemented a system like that, AI coding softwares will be able to automatically alter your Mac app to a form that could run on the iPad. Or, alternatively, more of these desktop apps could become web-hosted progressive web apps as that technology matures, and then you could create one app that could run on any platform. Personally, I think the signs are already there that Apple wants a unified App Store experience across their platforms, it just might be hard to get some developers to play nice. Also, if iPadOS supports sideloading, there’s not necessarily a reason a third party couldn’t make some type of emulation app that could run Mac apps on iPad, though maybe that would run afoul of some licensing or something. Of course I don’t know for sure if any of these things are going to happen, but that is my hunch, and I could be wrong, but I think the foundation is already in place, and I think I see signs that this is what Apple wants to do with the two platforms, keep macOS a desktop OS with a little more familiarity for iOS and iPadOS users, and give iPadOS (Apple’s modular/modern software solution) most or all of MacOS capabilities in a way that makes sense for touch-first input. And this idea even makes sense when you look at the hardware. The iPad now has hardware that could just about replace the low-end MacBook line, while the MacBook Pros and the Mac Desktops will always have an advantage in how much computing power they’re able to pack. Even if the software was nearly identical, the iPad wouldn’t completely kill the Mac, the Mac would just become a bit more niche, being used predominantly by professionals who need more computing power. And I think we’re almost there already. Sorry for the long comment, but these are the things I’ve been considering about this debate lately.
