While it has been around for over a decade, Handoff has been the gift that keeps on giving. A key part of Continuity, Handoff lets you move seamlessly between native Apple apps on your iPhone and Mac, like Notes, Safari, and more. To use Handoff between your iPhone and Mac, you'll need to fulfill some basic requirements. First, your iPhone and Mac need to run on at least iOS 8 and OSX Yosemite, respectively. Next, you'll need to be logged into the same Apple ID, plus have Wi-Fi and Bluetooth enabled. For this to work, you also have to make sure your two devices are within short proximity to each other.

To use Handoff, simply open one of the designated Apple apps on your iPhone, like Safari. Then, on your Mac, watch out for the app icon to appear on your dock with a little gray circle with an iPhone silhouette inside. When you hover over it with your mouse, it should have "From iPhone" under its app name.

Although Apple keeps Handoff on by default, you may have turned off this feature in the past. To turn it on again on iPhone, launch the Settings app > General > Airplay & Handoff and toggle on the button next to Handoff. While on Mac, go to System Settings > AirDrop & Handoff. Next, to Allow Handoff between this Mac and your iCloud devices, toggle on the button.
