Apple is bringing SMS text messages to the Mac. iMessage (Messages) works fine between Apple’s devices but neither Mac nor iPad can handle text messages to a phone number the way an iPhone can. OS X Yosemite on a Mac changes that.
With OS X Yosemite and an iPhone running iOS 8, you can send and receive SMS and MMS text messages right from your Mac. So when friends text you — regardless of what phone they have — you can respond from whichever device is closest. All the messages that appear on your iPhone now appear on your Mac, too. You can also initiate a text message conversation on your Mac by clicking a phone number in Safari, Contacts, or Calendar.
Which means you still have to have an iPhone to send SMS text messages (non-iMessage) from a Mac.
Most of the folks I interact with work with iMessages, but when I run into someone who doesn’t my workflow grinds to a halt. I have to pull my phone out of my pocket, type a response, perhaps wait for their response, all while switching between my phone and Mac.
What about iPad users?
