Downloading iOS/iPadOS 18.4.1, tvOS 18.4.1, and macOS Sequoia won’t bring any new features, but will fix major security vulnerabilities and other bugs.
You can download the iOS/iPad 18.4.1. update by going to Settings > General > Software Update on your iPhone or iPad.
For the mac, selecting the Apple Menu and then About This Mac. Select Software Update to start the process. The download is large, so expect the entire process to take more than an hour.
The Apple TV update should automatically be downloaded.
If you haven’t already enabled automatic updates, you can download the software by heading to Settings > System > Software Updates > Update Software. Right next to the button to update software is the toggle switch to turn on automatic updates.
