I want to change my contacts so they are all in first letter first name order like they are on my phone. I have googled similiar questions but people have said look up a file and drag it into your desktop. I dont understand this. only just bought a mac and its very confusing. Where are such files? when i open the address book where is the preferences tab or option as I cant even see it?? any help appreciated, spent far too much time on this already.
