Apple releases its first Background Security Improvement for macOS, iOS and iPadOS

Apple has started providing small security updates to iOS, iPadOS and macOS devices. These are background security enhancements that will deliver minor system updates between larger software updates. According to the company, these are intended to “provide lightweight security releases for components such as the Safari browser, the WebKit framework stack, and other system libraries that benefit from smaller, rolling security patches between software updates.”

These updates must be downloaded in the background, as the name suggests, although the device will need to be restarted to complete the process. In practice, we found that applying a background security enhancement was faster than a typical Apple software update. On an iPhone, the reboot was more like a power cycle taking less than a minute, compared to 5-10 minutes for a standard update that takes a device out of commission.

The first 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 viewed in the Privacy & Security section of the Settings menu.
