Apple reissues Rapid Security Response for iOS 16.5.1 and macOS 13.4.1

Apple reissues RSR patch for iPhone, iPad, and Mac

After pulling the Rapid Security Response for iOS, iPadOS, and macOS a few days prior, Apple has reissued the software updates.

Apple's Rapid Security Response (RSR) is a standard part of the company's security updates system. The whole point is to quickly address significant issues related to the software without forcing end users to wait for a full update.

However, when Apple issued the RSR for supported iPhones, iPads, and Macs, the company quickly pulled the new software following complaints that major websites were blocking Safari users from accessing content.

Apple confirmed it would reissue the updates soon, and Aaron Zollo was the first to notice the new updates being available now.

While the revised RSR is available now to download for iOS 16.5.1, iPadOS 16.5.1, and macOS 13.4.1, Apple has not updated its official security updates page as of the time of publication. It's expected the revised update will patch the same security issues the first update was meant to address.


  • Available for: iOS 16.5.1, iPadOS 16.5.1, and macOS Ventura 13.4.1
  • Impact: Processing web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited.
  • Description: The issue was addressed with improved checks.
  • CVE-2023-37450: an anonymous researcher

Apple devices are configured to implement Rapid Security Responses as the default setting automatically. If needed, users will receive a prompt to restart their device.

To enable "Security Responses & System Files" on an iPhone or iPad, navigate to Settings, then select General, followed by Software Update. From there, access Automatic Updates and ensure the toggle is turned on.

For Mac users, open the Apple menu by clicking on the Apple logo, then select System Settings. In the Settings window, click on General and Software Update, then Automatic Updates, and make sure the toggle is turned on for "Install Security Responses and system files."
