Previously when my girlfriend used either Messages on her phone or the OS X Messages app, all messages were sent via her phone number and were synced between the two. Now she got a new iPhone 6 and when she messages from her phone it is sent as a message, but when from her OS X Messages app it is sent from her @icloud.com address and is not synced with her phone. How do I fix this for her?
MacBook Air, OS X Yosemite (10.10)
First, check Settings > Messages, Send and Receive, and make sure her number is selected under "Start New Conversations From." If not, select it and try deleting the old message thread and sending a new conversation.
If that doesn't work, go to Settings > Messages > Facetime, and tap your Apple ID and choose Sign Out. Do the same thing on Settings > Messages, Send and Receive. Restart the iPhone, and sign back into Facetime and Messages, and see if the number is showing under Send and Receive.
iOS and OS X: Link your phone number and Apple ID for use with FaceTime and iMessage - Apple Support
Her number is selected under Settings > Messages > Send and Receive on her phone.
I don't see how signing out, restarting and back in could help?
Sending from @icloud.com email instead of phone number?
