In this episode, Tyler shows us how to automatically delete messages on iOS, iPadOS, and macOS.

By default, the Messages app on iOS, iPadOS, and macOS retains messages and conversations until you delete them. However, particularly if you receive a large number of attachments, messages can occupy a significant portion of space on your device. To automatically delete messages after a set amount of time after they've been received on iOS and iPadOS, go to Settings > Messages > Keep messages, and choose an option. To do the same on macOS, open Messages, choose Messages > Settings, (or press Command-Comma) click the General button in the toolbar, and choose an option from the "Keep messages" popup menu.
