Last time I applied Mojave theme on KDE Plasma and this time I want to apply similar thing onto GNOME 3. I use Fedora 29 as the basis, however, you can do it on any other GNU/Linux distro. As the composition, I use here McMojave as both Shell and GTK3 themes, and then Mojave-CT icon theme, plus two additional GSEs namely Desktop Icons and Dash to Dock. Don't worry even if you have no experience in desktop tweaking, as I have published GNOME customization preparations article before this tutorial. Go ahead, have fun, and enjoy!
