This article explains how to trigger an automatic Chromecast firmware update using the iOS and Android Google Home app. It also includes information on forcing an update on Windows, Mac, and Linux computers. These instructions apply to all generations of Chromecast and Chromecast Audio.

Google automatically releases new Chromecast firmware, so in most cases you should have the latest version available. However, these rollouts are often phased, so it may take a while to get the latest firmware version installed. Here’s what you can do to try and trigger an automatic update.

To check the latest firmware version available for your Chromecast device, visit Google's Chromecast support page.

If you haven't already, download the Google Home iOS app or the Google Home Android app.
