Apple has introduced a new kind of operating system upgrade that boosts security.

On iPhone, iPad, and Mac devices, the quick security responses are for iOS, iPadOS, and macOS.

According to Apple, the patches "deliver important security improvements between software updates."

For instance, they enhance the WebKit framework stack, the Safari web browser, and other essential system libraries.

According to Apple, "they may also be utilized to more quickly remediate some security issues, such as issues that might have been exploited or reported to exist "in the wild."

Only the most recent operating system versions receive the updates. With iOS 16.4.1, iPadOS 16.4.1, and macOS 13.3.1, that process starts.

The device enables automatic application of a quick security response, according to the business.

Device restarting will be essential if it's required.

Once the update has been installed, a letter is added after the software version number.

Users can look in their settings to determine whether these automatic updates are enabled.

Simply go to "general" in settings on an iPhone or iPad, tap "software update," choose "automatic updates," and make sure "security responses and system files" is enabled.

On a Mac, choose "System Settings" from the Apple menu. After that, click "general" and then "software update." Initially, click "show details" to confirm that "install security responses and system files" is turned on.

The Apple device will acquire the necessary fixes or mitigations when they are included in a subsequent software update, allowing users to disable the setting or refuse to use the available solutions.

According to The Verge, Apple first announced the quick security measures last year.
