Apple - iMessage's from Macbook send as my email instead of phone #

You need to sign up to use you appleID for iMessage with same appleID that you use with your MacBook (@aol email) on the phone.

This can be done by going to settings -> messages -> send & receive; and tapping the option, which reads something to the effect of "use appleID for iMessage".

Once it logs in and activated, Apple will associate the phone number with your email address and it should show up on the Mac. If it doesn't, try logging out and back in from iMessage on the Mac.
