Call of Duty®: Black Ops Mac Edition will take you behind enemy lines as a member of an elite special forces unit engaging in covert warfare. On your Mac running Yosemite, launch the FaceTime app, open its preferences, and enable the iPhone Cellular Calls option. When you receive a call, it will be routed from your iPhone to your Mac. Make calls in FaceTime on Mac. Make a FaceTime call to one or more people (up to 32 other people) who have a Mac, an iOS device, or an iPadOS device with the FaceTime app and are connected to the internet. FaceTime calls use Wi-Fi or cellular data. For information about system requirements for using FaceTime, see FaceTime requirements.
You can, in fact, make phone calls from your Mac. Wi-Fi (WiFi) calling is one of the perks you get when you choose to go with Apple’s complete eco-system. If you own an iPhone 5c or newer devices and one of the “Wi-Fi Calling” compatible devices (Mac, Apple Watch, iPod touch or iPad), you’re one step closer to making what Apple named “Wi-Fi calls on other devices.” It’s imperative that all your devices are properly registered under one Apple ID connected to one iCloud account.

All of the four major carriers in the U.S. support this method of calling on from your Mac, or “Other Devices.” If you wish to check whether your smaller carrier supports the feature, visit the Apple Support website.
By enabling Wi-Fi Calling on your Mac, you allow yourself more options for making or receiving phone calls. This is particularly handy if you receive a call when your iPhone is in another room when it rings. (I really have to stop leaving my iPhone on the kitchen counter when I get my morning coffee…)
