Some Mac users may have seen problems with Safari 9 especially after upgrading to El Capitan OS.
The problems seems to specifically affect some WordPress themes, thankfully the fix is an easy one.
Simply go to your theme options and in the custom css section add the following code
html:not(.mobile-true) #main img:not(.animate-element, .ls-s-1),
html:not(.mobile-true) #header img,
html:not(.mobile-true) #bottom-bar img {
opacity: 1 !important;
}
Click save and then visit the site to check.
