how can I delete old addresses from imessage
I have deleted all the old addresses both the e-mail, contacts and iMessage on my iPhone and it worked fine, but in my MacBook Air can not I delete old deleted addresses in iMessage. When I type a letter in the address line, I get all old deleted addresses proposals, the iPhone I deleted one by one, but it is not in the computer. It belongs to the point that many of the addresses are several years and several old computers and many were admitted during the time I was using the Microsoft, now I have the Mac, but I will not cry from the old recipient addresses. Please help me.
MacBook Air, OS X El Capitan (10.11.4)
