How do you disable click events from the contextmenu event when using Ctrl+Click in Safari for Mac?

You could make use of the ctrlKey property of the MouseEvent :

var div = document.querySelector('div');
div.addEventListener('click', function(e) {
  if (e.ctrlKey) return;
  e.preventDefault();
  alert('click!');
}, false);

div.addEventListener('contextmenu', function(e) {
  e.preventDefault();
  alert('context menu!');
}, false);

div {
  border: 1px solid red;
}

<div>hold ctrl+click in safari, chrome, etc</div>

So if you want to patch the context.js yourself, just add if(ctrlKey) return; l24.

l23    $(document).on('click', 'html', function (e) {
l24    if(e.ctrlKey) return;
l25    $('.dropdown-context').fadeOut(options.fadeSpeed, function(){
l26     $('.dropdown-context').css({display:''}).find('.drop-left').removeClass('drop-left');
l27     });
l28    });
