Manual Installation

How To Install:

Download
Extract to /usr/share/themes or ~/.themes (create it (in your home folder) if necessary);
Change via distribution specific tweak tool.

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)

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.

Uninstall

Run

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

Troubleshooting

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
