Manual Installation

How To Install:

  1. Download

  2. Extract to /usr/share/themes or ~/.themes (create it (in your home folder) if necessary);

  3. Change via distribution specific tweak tool.

After the installation is complete you can activate the theme with gnome-tweak-tool or a similar program by selecting OSX-Arc-White, OSX-Arc-Darker or OSX-Arc-Shadow as Window/GTK+ theme and OSX-Arc-White, OSX-Arc-Darker or OSX-Arc-Shadow as Gnome Shell/Cinnamon theme.

System Requirements

Note: If your distribution doesn't ship separate development packages you just need GTK 3 instead of the -dev packages.

For the theme to function properly, install the following

  • Gnome Shell, GTK 3.14 - 3.22
  • The gnome-themes-standard package
  • The murrine engine. This has different names depending on your distro.
    • gtk-engine-murrine (Arch Linux)
    • gtk2-engines-murrine (Debian, Ubuntu, elementary OS)
    • gtk-murrine-engine (Fedora)
    • gtk2-engine-murrine (openSUSE)
    • gtk-engines-murrine (Gentoo)


If previous versions were installed or existed, remove them first.

sudo rm -rf /usr/share/themes/{OSX-Arc-White,OSX-Arc-Darker,OSX-Arc-Shadow}

Arc-Dark for Ubuntu Software Center

The Arc Dark theme for the Ubuntu Software Center by mervick can be installed from here. It solves readability issues with Arc Dark and the Ubuntu Software Center.


If you have Ubuntu with a newer GTK/Gnome version than the one included by default (i.e Ubuntu 14.04 with GTK 3.14 or Ubuntu 15.04 with GTK 3.16, etc.) you have to install the theme manually as described above. This is also true for other distros with a different GTK/Gnome version than the one included by default


If you get artifacts like black or invisible backgrounds under Unity, disable overlay scrollbars with

gsettings set com.canonical.desktop.interface scrollbar-mode normal
