There seems to be a never-ending stream of Linux distributions based on Ubuntu 14.04 and you can add Deepin 2014 to that list. Instead of just using GNOME, KDE, LXDE or Xfce, Deepin has built its own desktop environment which has a definitive Mac OS X feel.
Deepin was originally known as Linux Deepin, but the developers decided to rename the operating system to simply Deepin.
