minimize, close, maximize buttons

Thanks, I tried as you said but they are still squared ( a bit different - and smaller )  I attached a screenshot
There must be a way to use the OSX style buttons
Right now I'm using a nice theme (Sierra visual style, no Icon Pack ) for Windows 10, and I love it
I do, actually, use OSX visual styles for Windows, since 2008

I tried a different theme from the Chrome web store ( black theme - Aero ) and now I have the OSX buttons, but I don't like the theme
The BOOKMARKS BAR is black
That means, the OSX buttons are not compatible with all the skins ?
