title: Codeigniter : vcf mime type not detected in mac safari
body: <p>I am facing problem while uploading vcf file on mac safari.</p>
  
  <p>I have added the vcf required mime types in config/mime.php. </p>
  
  <p>The upload functionality works very well in Mozilla and other browsers but on mac safari it is giving error: "The filetype you are attempting to upload is not allowed".</p>
  
  <p>I searched lot but all are saying regarding mime type that I have already added.
  I have added following mime type:</p>
  
  <p>'vcf' => array('application/octet-stream','text/x-vcard', 'application/vcard', 'text/anytext', 'text/directory', 'application/x-versit', 'text/x-versit', 'text/x-vcalendar')</p>
  
  <p>Do I need to do some thing extra for mac safari.
  Please let me know what I need to do.</p>
