Limited FaceBook friends show up in Contacts app in Mavericks or Yosemite I configured my Facebook account in OS X (both Mavericks &amp; Yosemite) using following article >> http://support.apple.com/kb/PH18993

I have 200+ friends on FB, but on Contacts app it just shows 38. Remaining are missing, I don't know what I have done wrong.

Moreover, I have allowed events and birthday calendar to sync as well, but not all birthday events are showing up in OS X calendar app.

Help much appreciated. Thanks.

p.s. I followed following article ( http://www.scrubly.com/blog/how-to-mac/how-to-set-up-social-media-accounts-in-mavericks-and-why/ ) as well, but result is same. Not all FB friends show up.
It is possible that only the contacts that have provided useful contact information to Facebook are showing up in your OS X Contacts app. This article suggests that Facebook would be no longer adding contacts with no contact info to to your address book: Facebook aims to declutter the iOS Contacts app by no longer syncing friends without useful contact info
