The following devices must be running Roku OS 9.4 or higher: To check what Roku model you have, go to 'Settings' from the Roku home screen, then select 'System' and 'About.' If you want to use it, you'll need a supported model. Or, you can mirror your entire screen to your Roku from the Control Center on your iPhone or iPad, or from the menu bar on your Mac. You can AirPlay content to your Roku from directly within apps and websites - like Hulu or HBO Max - on your iPhone, iPad, or Mac. That means you can display videos, photos, and other media on your TV. AirPlay, a useful casting feature on Apple products, allows you to stream media from your iPhone, iPad, or Mac to many different Roku models.
