My iMac Cannot Use iMessage Unless To An iPhone...
This is really strange.
For ages, I was sending text messages using iMessage to my cousin who does not have any Mac devices including her phone.
It seems like perhaps since upgrading to El Capitan, I can no longer send to her. I get a "MESSAGE NOT DELIVERED" result after sending a text.
However, if I send a message to another family member...one who has an iPhone, it sends just fine.
While this shows that perhaps my Mac has good taste, I'd rather be able to send an iMessage no matter what the recipient is using.
Any ideas?
Thanks
Tom
