I love the name Mac! He's so cute. I just know that he and Tiki will enjoy each others company and soon become best friends.

Just wanted to add a clarification to this statement. With normal whitefaces (which are a mutation of a normal grey cockatiel) the males do have white faces and the females have grey faces. However not all whiteface cockatiel mutations follow the same rule. Peid-whitefaces and lutino-whitefaces (or albino) cannot be visually sexed. Mac is a normal whiteface though, so yes he is indeed a male.
