The world of computing is very versatile. While Apple wants unsupported iOS apps to be unable to run on macOS. others get for example Linux can run almost normally on a Mac M1. There are even those who want the operating system intended only for computers to run without problems on other devices. That is what Yevgen Yakovliev has achieved with macOS Catalina and an iPad Pro.
The normal user uses an iPad for what Apple has intended it to be used for. The same goes for Macs and any other device. But there are always those who try to give a twist to the nut. This is Yevgen Yakovliev who has managed to run macOS Catalina on a 2020 iPad Pro. He has done it using the use of virtual software, something that is becoming more frequent and useful if you want, for example, to navigate safely (apart from using VPN).
Yakovliev has posted on the Internet, in Youtube, an explanatory video of about 40 minutes where it is explained How did you get macOS Catalina to work on an iPad Pro, in this case the 2020 model. One more proof of how efficient and productive virtual Hackintosh can be. More specifically, the author uses the UTM application to run virtual machines on iOS devices. Then you have employed a process to create a virtual Hackintosh with a shared method on GitHub called OSX-KVM. KVM is an open source kernel-based virtual machine utility built into Linux.
We won't know how Apple will handle this intrusion into its macOS software. We have already seen before how for similar things, the American company He has gone to court to defend what is rightfully his. We will wait to see Apple's response, if there is one. But for now, if you want to try on your own, you already know that you do it at your own risk.
