Hi, there are several issues with this theme in Chrome and Safari.

It works fine in firefox. I was told it does not work in Safari mac and in Chrome mac it also has issues. On chrome pc, there are problems when I tested it, and then I installed Safari PC and there are major issues. Parallax does not work.

Please look here: http://demo.megadrupal.com/?theme=birva , your demo in Safari parallax does not work.

Take a look here, my project: http://dev.madindustriesinc.com/

In safari the map also is a square not a circle as intended. I can confirm this is also the case for iPhone 5s, latest OS.

Thanks!
