Hi, Matt here and looking to spot your issue.
What exactly is the problem? I see your site on Apple (MacBook Pro) Safari browser quite well. The only problem I see is when I browse to few supporting pages, links show at the bottom. They show default layout with - as one page layout is used - not proper returning to home page (and other sections of it).
This issue could be simply changed by adding absolute links in all supporting pages.
If you have meant Safari on Windows, I would say to disregard it. It won't be supported, Apple does not have any interest there anymore.
Looking forward to your reply,
Matt
