Hey guys I'm new here and to the mac world but I was wondering if any of you could help me out. Currently my iPhone connects to my old windows computer. What I am afraid of is whether or not when I plug it into my new mac, will I lose all of my music, videos, contacts and apps or will it just transfer it into iTunes and everything will work just as it did before on my other computer. Regardless if it will erase everything or it will work perfectly, I would like to now the best course of action. Thanks in advance for all the support.
