Osx gtk3 Themes not working

[bksubhuti]

Hello,
I downloaded some mac themes from the suggested website on the mate themes place.
The theme applet would not select the themes I downloaded.
and when copied the themes manually to the .themes directory (and once to usr/share/themes), they also did not work. I had the theme listed in the Theme applet, but it had a question mark and would not work when I clicked on it.

I see this link here…

Help adding themes to Ubuntu Mate

Hello all I am mostly new to Linux, and to this forum, so please forgive me if I screw anything up in regards to my posting etc. or if this question has already been asked. If it has, I was not able to find it. I am having an issue with installing new themes into my Ubuntu Mate system. Firstly, I have tried to follow numerous guidelines and videos on how to do this. I download a zip folder of an icon theme from gnome-look and extract it, then I place it in the /usr/share/icons directory. …

and noticed that only gtk2 themes are supported.

1. If there is a way to install these gtk3 themes, please let me know.
2. Maybe someone should file a “usability” bug and request that the applet point one to gtk2 themes with a warning too.

If you will give me a download link, I will try it out. GTK3 is a work in progress.

Here are the two I tried (The first two I attempted to try… 100% fail)

1. http://gnome-look.org/CONTENT/content-files/175666-OSX-Arc-White.zip
2. https://codeload.github.com/rohithmadhavan/OSX-MATE/zip/master

Both fail.
Also, installing does not allow selection of zip files…I can use “all files” and see the zip, but then it will not install that way. I tried by copying, but as I said before… get the question mark icon.

Most of 16.04 is built on GTK2 with some programs that are GTK3, so there is compatibility if the theme supports GTK2 themes too (which OSX-Arc-White does).

16.10 is in development, but future releases aims to be GTK3 only.

I got OSX-Arc-White to work by clicking on Customise… and choosing the different parts of the theme – the controls and window border. The window border didn’t work under Compiz, but it does under Marco.
