Apple has started providing small security updates to iOS, iPadOS and macOS devices. These are dubbed Background Security Improvements that will offer minor system updates between the larger software updates. According to the company, these are meant to "deliver lightweight security releases for components such as the Safari browser, WebKit framework stack, and other system libraries that benefit from smaller, ongoing security patches between software updates."
These updates should download in the background, as the name implies, although the device will need to be restarted to complete the process. In practice, we found that applying a Background Security Improvement was faster than a typical software update from Apple. On an iPhone, the restart was more of a power cycle taking under a minute compared with the 5 to 10 minutes a standard update takes a device out of commission.
The inaugural Background Security Improvement was released today with a patch for WebKit. These updates will be supported and enabled on devices running iOS 26.1, iPadOS 26.1 and macOS 26.1. Details can be reviewed under the Privacy & Security section of the Settings menu.
