Two pretty popular GTK3 themes have been updated to work with the latest stable GTK 3.6 recently: Zukitwo and Adwaita Cupertino (now called Gnome Cupertino).

Gnome Cupertino (previously known as Adwaita Cupertino) is a GTK2/3 theme pack based on the colors of Mac OSX Snow Leopard and Lion, each with variations optimized for either GNOME Shell or Unity.

Because Adwaita Cupertino was practically re-written from scratch in the transition to GTK 3.6 and also, since the theme doesn't uses the Adwaita Engine for several versions, its designer decided to rename it to Gnome Cupertino.





The package available in our PPA has two themes: the default Gnome Cupertino and a variant optimized for Unity, but inside the theme folder (e.g. /usr/share/themes/Gnome-Cupertino) you'll find some alternate Metacity / Unity buttons which you can use, but you must make the changes manually - see the readme.txt file inside the theme folder. In the same file you can also tweak the theme to use a custom style for Nautilus 3.4 because by default, it's optimized for Nautilus 3.6.

Since the theme has just been ported to GTK 3.6, there are some bugs. For instance, the GNOME Classic indicators have a weird white border at the bottom. Hopefully this will be fixed in future versions.

To add the WebUpd8 themes PPA and install Gnome Cupertino in Ubuntu 12.10 or 13.04, use the following commands:

sudo add-apt-repository ppa:webupd8team/themes sudo apt-get update sudo apt-get install gnome-cupertino-gtk-theme

Zukitwo, one of the most popular theme packs has finally been updated for GTK 3.6. In the process, the theme lost yet another variant (Zukitwo Dark) so there is now only one Zukitwo theme.





Just like Gnome Cupertino, Zukitwo has a few bugs and the theme doesn't look too good with the classic GNOME session panel. Hopefully they will be fixed soon. Also, the theme no longer uses the Unico GTK3 engine and the buttons have been replaced with the ones used in the Zukini theme Just like Gnome Cupertino, Zukitwo has a few bugs and the theme doesn't look too good with the classic GNOME session panel. Hopefully they will be fixed soon.

To install the latest Zukitwo GTK2/3/GNOME Shell/Xfwm theme pack in Ubuntu 12.10 or 13.04, use the commands below:

sudo add-apt-repository ppa:webupd8team/themes sudo apt-get update sudo apt-get install zukitwo-theme
