Have you heard the rumors about Apple’s new security updates feature on iPhone, iPad and Mac? This feature, called Rapid Security Response, can keep your devices updated when a flaw is found in a recent system update.

Let’s see what Apple Rapid Security Response is and how to enable it to improve the security of your devices.

What is the Apple Rapid Security Response Update?

Rapid Security Response is a system that Apple uses to frequently send security patches to device users. This feature was introduced in iOS 16.2, iPadOS 16.2, and macOS 13.2.

In some cases, you may not need to restart your device after these updates. However, if the fixes from Rapid Security Response affect the operating system, your device may need to be restarted.

These security updates apply to the latest version of the operating system. Thus, if the OS update is delayed, the security update will also be delayed.

Rapid response security release Includes lowercase letters beginning with “a”. For example, you might see “iOS 16.4 (a)” as the build number. If there is more than one update, it will contain more characters like “a”, “b”, “c”, etc.

While this update feature may be enabled by default on your Apple device, here is how you can check and enable it manually.
