Hi,
I am new to the MAC OS and trying to get the iMessage working but without any chance, once I try to send an iMessage to one of my contact, i get a request to login since the iMessage is inactive, I logged in successfully but still I am not able to send any messages as the problem is still there.
Will you please be so kind and let me know what to do in this case?
I am using MacBook Pro 13" early 2015 with Yosmite Version 10.10.5.
Looking to hear from you
MacBook Pro (Retina, 13-inch,Early 2015)
