i/Text Messaging on a Macbook Pro
In addition to our iMac, my wife also has an iPhone and a Macbook Pro. She is able to send i/text messages on both our iMac and her iPhone, but not her Macbook Pro. Is this because she can only send from two devices, or can you send from more than two devices, which means there is another issue that needs to be addressed?
Thank you and regards,
