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.

  • Emily's Favorite Mac Accessories

    I am the kind of gal that admittedly likes gadgets and accessories just because they are cool, I don’t even need to have a use for them to make me want one! If there is a new iPad case, a new speaker, a new product announcement from Apple, I want it. This has resulted in a vast collection over the years of all kinds of gadgets, gizmos and some stuff that I just hang onto for no good reason other than I might need it one day. Some things have been a bit of a fad, others have stood the test of time. Over the years I have found that I few items in my collection of gadgets that have either become invaluable or the kind of item that really stands the test of time.

    My first must have and favorite gadgets are portable bluetooth speakers, and I have had several over the years. The battery powered speakers from Skullcandy I had were one of my most favorite pocket sized speakers! It took up little room in my bag and I could have my music wherever I wanted. You never realize how much you miss having music wherever you go until you start to use these kinds of speakers and then suddenly don’t have them! I eventually outgrew my little Skullcandy speakers and upgraded to a larger but still portable Altec system. This speaker system went everywhere with us. In fact, it still travels with us in our camper even though it features a 30 pin connection for our phones. What I loved most about this set up was that it had a rechargeable battery, so unlike my little Skullcandy speakers I didn’t need to worry about carrying around spare AA batteries. It also allows me to use a 3.5mm headphone cable and an FM radio. I recently started to use the “**Outdoortech Turtle Shell**”:http://www.smalldog.com/product/85338/outdoor-tech-turtle-shell-2-0-rugged-wireless-boombox-electric-blue speakers to replace the old Skullcandy speakers for immediate portable sound, and as a huge bonus this speaker is bluetooth, something none of my previous portable units had. I will admit, I still haven’t found a better replacement for my aging Altec portable speaker as far as sound quality goes, but I will also admit finding a newer solution would require my having to let go!

    My second must-have gadget is an airport express base station. You might be surprised that it is not the Airport Extreme. Why do I love the “**airport express**”:http://www.smalldog.com/product/80932/apple-airport-express-base-station-802-11n-wi-fi so much? Well part of it might be a bit nostaglic. It was my first introduction into wireless speakers. How cool was it to plug in my Harmon Kardon speakers, simply tap my iPhone while sitting on the couch, and my speakers came to life like magic? But the great features don’t stop there. It’s a really powerful and inexpensive wireless router. For many, we don’t have huge areas we need to cover with wireless. Maybe it’s just a small apartment, or perhaps your house just isn’t that big. When I first started to use the airport express the one draw back was that the only ethernet port had to be designed (in most cases) for your internet modem, but in recent years Apple has added a second ethernet port allowing for more flexibility and versatility with this little gem.

    iPad and iPhone cases are another huge weakness of mine. I probably have no less then five cases for my phone and for my iPad. You could say I collected cases like some girls collect shoes! But on a serious note, this is a very important accessory for your iPhone or your iPad. Some folks prefer form fitting and minimal, others prefer a more rugged case. I have come to prefer several cases. However, I think cases that combine both slim form factor and serious protection are the “**Lifeproof**”:http://www.smalldog.com/wag900002119 cases. I have one for my phone and one for my iPad. What I love most of them is that they come off easily! I don’t always want a heavy duty case on my devices, but have found that many cases that offer greater levels of protection end up being very difficult to take off your device.
