Menu doesn't stretch properly in Safari

My web address is www.poipubeachestates/wordpress. The top menu stretches and shrinks perfectly in all browsers except for Safari on Mac. In that browser, all of the menu items overlap even though the screen resolution should allow for them to stretch farther.

Unfortunately, I don’t own a Mac and the last version of Safari made for Windows was in 2013, so I only confirmed this via TeamViewer on my client’s Mac. Chrome on his Mac rendered the menu fine.

Can anyone with a Mac load the site and confirm the issue? Is there code I can add so the menu will render properly in Safari?

I’m using Menu Images plugin (Menu Image, Icons made easy – WordPress plugin | WordPress.org) with WordPress 4.8.1 and the latest version of Travelify

Quick follow up, I installed Safari for Windows 5.1.7 (the last version of Safari for Windows) and the menu doesn’t even show up. I was thinking div min-width might help, but not if the menu doesn’t even show up.
