I love that I can text from my Mac and I use it all the time. Over the past week I've had trouble sending texts to two of my friends (individually). The texts say "Not Delivered". It's only two of my contacts.
I've verified their information. I've quit Messages, rebooted, then rejoined Messages. I've followed instructions that I got from Google. The problem is that all other texts go through just fine.
Help?!?!? (And thank you).
