There have long been devices that allowed you to use your Mac as a speaker phone. In the long ago, you’d plug some device into a phone jack in your wall (assuming you even had such a thing), then plug another cable into your Mac. The results were spotty at best. Nowadays, you’ve got solutions like iChat and Skype, but they don’t connect to your iPhone.

With the combination of Yosemite and iOS 8, you’ll get a notification on your Mac when your iPhone rings, giving you the option of accepting the call, or ignoring it. You can answer the call from your iPhone, of course, but having the ability to minimize the interruption, keep your focus on your Mac, is a godsend to me.

From Apple’s web site:

Now you can make and receive iPhone calls right on your Mac. When your iPhone rings, you’ll get a notification on your Mac showing you the caller’s name, number, and profile picture. Click the notification to answer, and your Mac becomes a speakerphone. You can also decline the call or respond with a quick iMessage. Making a phone call from Mac is just as easy. Just click a phone number you see in Contacts, Calendar, Messages, or Safari. Dial in to a conference call from a Calendar event, and your Mac automatically enters the passcode for you. And if your iPhone rings while it’s charging in the bedroom, you can answer the call on your Mac in the living room — they just have to be on the same Wi‑Fi network. Because it works with your existing iPhone number, there’s nothing to set up. Just point, click, and say hello.

So if my phone is upstairs, and I’m downstairs on the couch with my laptop, I can still make and receive calls. Genius!
