What's insane about this is that it's usually considered flat-out impossible because of how much has changed over time between compilers and systems but apparently I can pull off building a kernel from 2009-2011 on a 2025 kernel. (Yes, I refuse to update macOS or my iPhone. I fucking hate my country.) I don't have high hopes for a successful boot though. Just because it compiled and linked doesn't mean it'll boot. If it does, I'll probably start something with this related to IPPCM.

Like even compiling a kernel for macOS 12 or 13 on macOS 26 is usually a dead end without a lot of hacking the build system and code to cooperate, not to mention the endless barrel of dependencies. Am I the best non-Apple-employee developer to ever get multiple XNU versions running myself without scripts or online guides and even get it building on modern systems? Could I open up a path to compilation on other POSIX/UNIX OSes?
