I wonder why there isn't any equivalent of Wine for running Mac software on Ubuntu. Thoughts?
The best we got was an attempt in 2007-ish called mac on linux as a virtualization tool to run Mac OS.

1 more issue: you are not allowed to run Mac OS software legally on non Apple hardware. Someone who creates it will get sued in an instant and no one will be able to ship it with their OS.
Edit: http://opensource.apple.com/ provides the iOS and Mac OS kernels, which are licensed under free software licenses (it is legal to run on your non-Apple, since otherwise it would be non-free). Basically it is illegal to run the Mac OS itself on non-Apple hardware, but legal to run software based on Mac OS on non-Apple hardware.
Now, there's 'Darling':
In it's early stages, but it works.
