It’s common knowledge that iMessages can sync between Apple devices. This feature isn’t just restricted to Apple’s iOS devices. You can get iMessages and even text messages pushed to your desktop. Much like iMessages, you can also get incoming call alerts from iOS on macOS. In fact, you can answer these calls on your Mac too. It’s a feature that needs to be enabled. Here’s how.
In order for this feature to work, you need to make sure you have iCloud enabled on the iPhone, and the Mac. You must also be using the exact same Apple ID on both these devices.
To double check the connection/Apple ID, open the Settings app on your iPhone and tap your ID at the top. Scroll down and your Mac should appear as a listed device.
On your Mac, open the System Preferences app and click Apple ID. At the bottom of the left column, your iPhone should be listed as a connected device.
Once you’ve made sure that the devices are using iCloud and the same Apple ID, make sure you have iMessages, and FaceTime enabled on both/all of them.
On your iPhone, open the Settings app, and tap Phone. Look for the ‘Calls on Other Devices’ option, and tap it. Turn on the ‘Allow Calls on Other Devices’ option, and select the device(s) you want to get call alerts on.
Once you’ve done that, you will get call alerts on your Mac. You will be able to see who is calling, accept the call, and dismiss it from the alert. If you miss a call, the alert will stack in Notification Center and you can view it there.
You don’t have to enable Calls on Other Devices for every single Apple device you have. If you have more than one Mac, or an iPad, you can forgo enabling the feature for those devices. The setting for it is on your iPhone. That’s where you decide which apps can and cannot get call alerts from your iPhone.
If the feature doesn’t work, i.e., you’re unable to get call alerts, go to the Settings app on your iPhone, select Phone, and tap on the Calls on Other Devices option. Check if Wi-Fi calling is enabled. If it is, turn it off, and the alerts should appear. This isn’t a bug. Apple has designed it to work this way. If you want call alerts on macOS, you have to forgo using WiFi calling.
