Why use a Linux Distro that mimics Mac OS X when you can have one that pirates it instead? From the glorious Democratic People's Republic of Korea, under the auspices of Grand Marshal of the Korean People's Army and the recenty-promoted (until the Recdep revises this) to the Chairman of the Workers' Party of Korea, Great Leader Kim Jong-un, comes Red Star Linux, the only Linux distribution not touched by imperialist hands! (well, except for the pirated parts).
WARNING!
This is a JOKE! See the Pro section if you don't know why this is funny. It is strongly recommend that you DO NOT TAKE THIS LITERALLY. The link does provide downloads of the 3.0 Server and Desktop versions, but again, PLEASE do not run them outside of a very tightly sandboxed virtual machine.
Specs
Pros
Pro Uses pirated Mac OSX UI
Since the great infallible leader basically pirated the graphics and UI from Mac OS X, Mac users should feel right a home with this one.
Cons
Con Watermarks your files
A small price to pay, however, for such a magnificent body of work. Besides, what's the harm in Big Brother, I mean CoWPK and GMoKPA, Great Leader Kim Jon-Un, and his trusted team of freedom warriors tracking your data? After all, someone has to be responsible for executing anyone who is watching imperialist media!
