HI I am new at this so bare with me. I have a mac and I inputted all my contacts. Names, address, numbers etc.. Last names are in the last name category. However, I can't seem to get my address book to alphabetize a-z according to last name. All the names are just all over the place by first name that isn't even alphabetized. What did I do wrong and how the heck do I fix it. Any help would be great. Thank you.
