I post photos from phone or computer from OS X to Facebook and all the previous comments and LIKES from previous posts attach themselves to the current post???
I'm sorry, but your comment is in the form of a question without actually being a question. Having said that, are you asking why your previous comments and likes attach themselves to your current post(s)? If so, I do not know because I don't have a Facebook account, but hopefully, someone who does will reply soon.
