I thought Yosemite would allow iMac to text non-iphone users.
I updated my iMac with Yosemite and everything is working well. However, I am unable to use the Messages app to text non-iphone users. According to the Apple page that describes the new Yosemite features it says:
SMS
More ways to get your message across.
With OS X Yosemite and an iPhone running iOS 8, you can send and receive SMS text messages right from your Mac. So when friends text you — regardless of what phone they have — you can respond from your Mac or your iPhone, whichever is closest.2 All the messages that appear on your iPhone now appear on your Mac, too, so your conversation is up to date on all your devices. You can also start an SMS or iMessage conversation on your Mac by clicking a phone number in Safari, Contacts, Calendar, or Spotlight.
I've tried clicking on the intended recipient's number in my Contacts, and typing the number in manually, but I get the message "Your message could not be sent. XXXXXXXXXX is not registered with iMessage." Does anyone have any suggestions?
iMac, OS X Yosemite (10.10)
