Can't send messages (Not registered in iMessage error)
Hi, I'm new with MacOS, I don't have an iPhone...
Today I signed in my Macbook's FaceTime with my AppleID, everything was OK, I could talk to a friend without problems.
After that I went to messages, I put my AppleID as account iMessage, no problem, the bill leaves me avtivada and all fine except when I try to send a message to the same friend with whom I spoke through Facetime, tell me your not registered mail, I tried using your gmail mail (the same as used for facetime) and using your iCloud mail, and does not work, nor with that friend, or any other, I hope you can help me.
A greeting and thanks!
PS. Sorry for my google transalate English.
