iOS/iPadOS has way more optimizations under the hood than macOS does in order to keep heat/battery life/performance not poor, the most obvious feature being the way apps and tabs get killed or refreshed in the background.

I don’t think Apple should or even would allow any sort of bare metal macOS mode on their mobile devices, but at least for iPads with M chips I could see them offering macOS via VMs. We know hardware acceleration works, there’s a working virtualization app that runs macOS at native speeds on jailbroken iPads.

I get why they do it, but it sucks that at least at minimum we don’t have a mode that turns it into basically iPadOS when connected to an external monitor, even if the performance and heat problems would be worse. But making that feature available and exclusive to the Duo would have made it more appealing.
