Once you have a WebView, there is an undocumented method which can enable WebGL:

WebPreferences *p = [webView preferences];
if ([p respondsToSelector:@selector(setWebGLEnabled:)]) {
    [p setWebGLEnabled:YES];
}

In this example I have protected it with respondsToSelector: to ensure the code will not abort if later versions remove this specific option.

Note that I understand that an application containing code using undocumented interfaces may be rejected if submitted to Apple's Mac App Store.

Another option is to use a different embedded renderer which officially supports WebGL (where Apple's WebKit as demonstrated in Safari only has it as a developer option, presumably intended to be experimental). Since both Firefox and Chrome support WebGL, have a look at Gecko and Chromium Embedded Framework. (Note: I have not been able to confirm whether whether embedded Gecko supports WebGL.)
