Apple Starts Releasing Rapid Security Responses for the iPhone, iPad, and Mac

ByEmily Dolloff

By now, you’ve probably seen a new form of update for iOS, iPadOS, and macOS: the Rapid Security Response. Early in May, Apple released the first instances of these updates, which the company had promised for iOS 16, iPadOS 16, and macOS 13 Ventura when those operating systems were first announced. Let’s answer some of the questions we’ve been hearing.

What are Rapid Security Responses?

Rapid Security Responses are security updates that Apple wants to distribute as quickly and broadly as possible. Users often delay installing standard operating system updates because they’re huge downloads, interrupt work for a long time while installing, and occasionally cause new problems.

To address these concerns, Rapid Security Responses are much smaller, install far more quickly (sometimes without a restart), and can easily be removed if they cause problems.

What security vulnerabilities do Rapid Security Responses address?

Apple released no security notes for its first set of Rapid Security Responses, and we don’t anticipate that changing for future releases. The point of a Rapid Security Response is to block a serious vulnerability that’s likely being exploited in the wild, and Apple doesn’t describe such fixes until it has patched vulnerable operating systems, including older versions, tvOS, and watchOS, none of which can take advantage of Rapid Security Responses. If this last set of updates is any indication, Apple will identify the Rapid Security Response fixes in security notes for the next full operating system update, which will also include the same fixes.

How do I install a Rapid Security Response?

Rapid Security Responses use the same software update mechanism as Apple’s other operating system updates. You can and generally should let Rapid Security Responses install automatically. That’s the default, but check to make sure.

  • iOS/iPadOS: Go to Settings > General > Software Update > Automatic Updates, and look at “Security Responses & System Files.”
  • macOS: Go to System Settings > General > Software Update, and click the ⓘ next to Automatic Updates. Then look at “Install Security Responses and system files.”

On recent iPhones and Macs, the installation time was quick, with the device being ready to use again within 2–4 minutes, including a restart. Older devices took longer, and future Rapid Security Responses may take more or less time.

How can I revert if a Rapid Security Response causes a problem?

Apple makes this easy in both iOS/iPadOS and macOS, with the amount of time being roughly similar to how long the Rapid Security Response took to install:

  • iOS/iPadOS: Go to Settings > General > About > iOS/iPadOS Version, tap Remove Security Response, and confirm the action.
  • macOS: Go to System Settings > General > About, click the ⓘ next to the macOS version, click Remove & Restart, and confirm the action.

How can I tell if I’m running a Rapid Security Response?

With this first Rapid Security Response, iOS and iPadOS both posted a notification informing the user of the update; macOS did not.

More generally, devices updated with a Rapid Security Response will have a letter after their version number, such as 16.4.1 (a), and the letter will disappear with the next full update, such as iOS 16.5. To determine what version your devices are running:

  • iOS/iPadOS: Go to Settings > General > About, and look at the iOS/iPadOS Version line.
  • macOS: Choose About This Mac from the Apple menu, and look at the macOS line.

Given what we know now, we recommend that everyone install Rapid Security Responses as soon as they’re available. If you notice a problem afterward, you can remove it. The only caveat is that if your employer manages your device, they may prefer to delay the Rapid Security Response installation until they’re comfortable with the changes.

Social Media: In an effort to protect users from security vulnerabilities that are being actively exploited, Apple has introduced Rapid Security Responses, which are security updates that are quick to download, quick to install, and easily removed if necessary.

  • _Dear Friends,_

    I tuned into the Apple special “Let Us Loop You In” event on my Apple TV. We will talk about the new hardware and software but there were a few things that caught my attention that really help to define Apple as a truly different company.

    The first was Apple’s environmental commitment. They now boast that 90% of their operations, worldwide, are powered by renewable energy and 100% in the USA. This is a unique accomplishment that is made even more remarkable by Apple’s size. While Small Dog Electronics is proud to power our Waitsfield headquarters and S. Burlington store by solar energy, we have not yet reached the point of powering all our operations which is something Apple has done both by purchasing renewable energy and installing large scale solar arrays at their locations both in the USA and China.

    Their environmental commitment goes further with an awareness of the impact their products have on the waste stream. They made a point to describe the materials used which have lower impact and talked about their recycling program, too. The robot, Liam, that disassembles iPhones into its component parts was very cool and is a further demonstration of Apple’s leadership in environmental stewardship.

    The other part of the announcement that caught my eye was the extension of Apple’s altruistic Research Kit tool that has helped researchers gather data on several chronic diseases. CareKit takes that a step further, offering tools that help patients and their medical providers manage those chronic diseases. They already have several new apps in development, including one that provides post-surgical care monitoring and another for diabetes monitoring. Research Kit and CareKit are both open-source software that do not necessarily provide any revenue stream for Apple but provides the tools to improve health. I am very proud of Apple for its initiatives in these areas.

    Last week a typo slipped by our proofers. Command+M is not open a new document but that command is Command+N. Sorry about that. To make up for it here are a couple more keyboard combinations you might find handy:

    **Command-Option-Esc** – If an app stops responding, you might need to force it to quit. You can do that with a right click on the app icon in the dock, but it’s even easier if you hit this keyboard shortcut. This will bring up the Force Quit dialog, which you can then use to make that non-responsive app quit. You might need to Command-Tab you way out of an active frozen app first, though, or use **Command+Shift+Option+Esc** to quit the currently active app.

    **Command-Option-P and R** – Here’s one that might challenge your fingers dexterity. Fortunately, you will hardly ever have to use it but it is used to reset your non-volatile random access memory (NVRAM). Information stored in NVRAM can include speaker volume, screen resolution, start-up disk selection and recent kernel panic information. If you are asked to reset your P-Ram or NVRAM here’s how you do it.

    1) Shut down your Mac
    2) Turn on your Mac
    3) Immediately after you hear the start up sound, hold down the command, option, P and R keys
    4) Hold those keys down until you hear the start up sound again and then release them.
