macOS does in fact runs well* on Linux, see: https://github.com/dockur/macos

Edit: Well-ish, as there's no GPU acceleration as noted in the comments below.

For some values of "well". No GPU acceleration means it's incredibly sluggish and plagued with rendering issues. There's also some sort of incompatibility around clock sources, which can result in the VM crashing during startup if you assign more than one core to it. There are ways around it but if you're unlucky enough they result in a massive perf hit.

This is cool, I'd be a bit hesitant to sign into my Apple Account with it though. I've had Apple shut down my account with Hackintosh's in the past.
