I often have messages "not delivered". I have the correct number and can send it from my phone but not from my iMac. The recipient is in my contacts. Help.
Some messages I try to send from my iMac are not delivered. They are marked "not delivered". These same messages can be sent from my phone just not from my computer. The messages are to people who are in my contacts and the numbers are correct. They just don't deliver.
