With any device that runs software, be it a smartphone, tablet, or computer, sometimes the easiest way to fix an issue is to restart the device.
Apple’s latest set-top box is no different. We’ve already shown you how to force-close problematic apps using a multitasking interface that’s reminiscent of iOS 8. But if you find your Apple TV is suffering from poor overall performance, you can try restarting the device by going Settings > System > Restart.
Alternatively, if the device is unresponsive you can use the Apple TV remote to force restart the unit.
To force restart the new Apple TV, press and hold both the Menu and Home buttons. (The Home button has the silhouette of a TV or monitor on it.)
After holding in both buttons for roughly 10 seconds, the white light on the Apple TV box will begin flashing. Once that happens, let go of both buttons and the Apple TV will restart.
