When our iPhones are in our pockets, we rarely miss a call, but when we’re working at our desks we don’t always hear it buzzing. Yosemite understands this predicament. A notification banner will alert you when a call is coming in on your iPhone, and you can answer it right on your Mac. And you can make calls, too; simply click a number in Contacts or Safari and it’ll start dialing, just like magic. (MacLife)
