OpenAI’s GPT-5 model went live for most ChatGPT users this week, but lots of people use ChatGPT not through OpenAI’s interface but through other platforms or tools. One of the largest deployments is iOS, the iPhone operating system, which allows users to make certain queries via GPT-4o. It turns out those users won’t have to wait long for the latest model: Apple will switch to GPT-5 in iOS 26, iPadOS 26, and macOS Tahoe 26, according to 9to5Mac.
Apple has not officially announced when those OS updates will be released to users’ devices, but these major releases have typically been released in September in recent years.
GPT-5 purports to hallucinate 80 percent less and heralds a major rework of how OpenAI positions its models; for example, GPT-5 by default automatically chooses whether to use a reasoning-optimized model based on the nature of the user’s prompt. Free users will have to accept whatever the choice is, while paid ChatGPT accounts allow manually picking which model to use on a prompt-by-prompt basis. It’s unclear how that will work in iOS; will it stick to GPT-5’s non-reasoning mode all the time, or will it utilize GPT-5 “(with thinking)”? And if it supports the latter, will paid ChatGPT users be able to manually pick like they can in the ChatGPT app, or will they be limited to whatever ChatGPT deems appropriate, like free users? We don’t know yet.
Apple has released the fourth developer betas of iOS 26, iPadOS 26, macOS 26 and its other next-generation software updates today. And along with their other changes and fixes, the new builds are bringing back Apple Intelligence notification summaries for news apps.
Apple disabled news notification summaries as part of the iOS 18.3 update in January. Incorrect summaries circulating on social media prompted news organizations to complain to Apple, particularly after one summary said that Luigi Mangione, alleged murderer of UnitedHealthcare CEO Brian Thompson, had died by suicide (he had not and has not).
Upon installing the new update, users of Apple Intelligence-compatible devices will be asked to enable or disable three broad categories of notifications: those for “News & Entertainment” apps, for “Communication & Social” apps, and for all other apps. The operating systems will list sample apps based on what you currently have installed on your device.
All Apple Intelligence notification summaries continue to be listed as “beta,” but Apple’s main change here is a big red disclaimer when you enable News & Entertainment notification summaries, pointing out that “summarization may change the meaning of the original headlines.” The notifications also get a special “summarized by Apple Intelligence” caption to further distinguish them from regular, unadulterated notifications.
This new process is fundamentally different and more secure than traditional credential export methods, which often involve exporting an unencrypted CSV or JSON file, then manually importing it into another app. The transfer process is user initiated, occurs directly between participating credential manager apps and is secured by local authentication like Face ID.
This transfer uses a data schema that was built in collaboration with the members of the FIDO Alliance. It standardizes the data format for passkeys, passwords, verification codes, and more data types.
The system provides a secure mechanism to move the data between apps. No insecure files are created on disk, eliminating the risk of credential leaks from exported files. It’s a modern, secure way to move credentials.
The push to passkeys is fueled by the tremendous costs associated with passwords. Creating and managing a sufficiently long, randomly generated password for each account is a burden on many users, a difficulty that often leads to weak choices and reused passwords. Leaked passwords have also been a chronic problem.
Passkeys, in theory, provide a means of authentication that’s immune to credential phishing, password leaks, and password spraying. Under the latest “FIDO2” specification, it creates a unique public/private encryption keypair during each website or app enrollment. The keys are generated and stored on a user’s phone, computer, YubiKey, or similar device. The public portion of the key is sent to the account service. The private key remains bound to the user device, where it can’t be extracted. During sign-in, the website or app server sends the device that created the key pair a challenge in the form of pseudo-random data. Authentication occurs only when the device signs the challenge using the corresponding private key and sends it back.
This design ensures that there is no shared secret that ever leaves the user’s device. That means there’s no data to be sniffed in transit, phished, or compromised through other common methods.
As I noted in December, the biggest thing holding back passkeys at the moment is their lack of usability. Apps, OSes, and websites are, in many cases, islands that don’t interoperate with their peers. Besides potentially locking users out of their accounts, the lack of interoperability also makes passkeys too difficult for many people.
Apple’s demo this week provides the strongest indication yet that passkey developers are making meaningful progress in improving usability.
CUPERTINO, Calif.—When Apple Senior Vice President of Software Engineering Craig Federighi introduced the new multitasking UI in iPadOS 26 at the company’s Worldwide Developers Conference this week, he did it the same way he introduced the Calculator app for the iPad last year or timers in the iPad’s Clock app the year before—with a hint of sarcasm.
“Wow,” Federighi enthuses in a lightly exaggerated tone about an hour and 19 minutes into a 90-minute presentation. “More windows, a pointier pointer, and a menu bar? Who would’ve thought? We’ve truly pulled off a mind-blowing release!”
This elicits a sensible chuckle from the gathered audience of developers, media, and Apple employees watching the keynote on the Apple Park campus, where I have grabbed myself a good-but-not-great seat to watch the largely pre-recorded keynote on a gigantic outdoor screen.
Federighi is acknowledging—and lightly poking fun at—the audience of developers, pro users, and media personalities who have been asking for years that Apple’s iPad behave more like a traditional computer. And after many incremental steps, including a big swing and partial miss with the buggy, limited Stage Manager interface a couple of years ago, Apple has finally responded to requests for Mac-like multitasking with a distinctly Mac-like interface, an improved file manager, and better support for running tasks in the background.
But if this move was so forehead-slappingly obvious, why did it take so long to get here? This is one of the questions we dug into when we sat down with Federighi and Senior Vice President of Worldwide Marketing Greg Joswiak for a post-keynote chat earlier this week.
It used to be about hardware restrictions
People have been trying to use iPads (and make a philosophical case for them) as quote-unquote real computers practically from the moment they were introduced 15 years ago.
But those early iPads lacked so much of what we expect from modern PCs and Macs, most notably robust multi-window multitasking and the ability for third-party apps to exchange data. The first iPads were almost literally just iPhone internals connected to big screens, with just a fraction of the RAM and storage available in the Macs of the day; that necessitated the use of a blown-up version of the iPhone’s operating system and the iPhone’s one-full-screen-app-at-a-time interface.
“If you want to rewind all the way to the time we introduced Split View and Slide Over [in iOS 9], you have to start with the grounding that the iPad is a direct manipulation touch-first device,” Federighi told Ars. “It is a foundational requirement that if you touch the screen and start to move something, that it responds. Otherwise, the entire interaction model is broken—it’s a psychic break with your contract with the device.”
Mac users, Federighi said, were more tolerant of small latency on their devices because they were already manipulating apps on the screen indirectly, but the iPads of a decade or so ago “didn’t have the capacity to run an unlimited number of windowed apps with perfect responsiveness.”
It’s also worth noting the technical limitations of iPhone and iPad apps at the time, which up until then had mostly been designed and coded to match the specific screen sizes and resolutions of the (then-manageable) number of iDevices that existed. It simply wasn’t possible for the apps of the day to be dynamically resized as desktop windows are, because no one was coding their apps that way.

Of course, those hardware limitations no longer exist. Apple’s iPad Pros started boosting the tablets’ processing power, RAM, and storage in earnest in the late 2010s, and Apple introduced a Microsoft Surface-like keyboard and stylus accessories that moved the iPad away from its role as a content consumption device. For years now, Apple’s faster tablets have been based on the same hardware as its slower Macs—we know the hardware can do more because Apple is already doing more with it elsewhere.
“Over time the iPad’s gotten more powerful, the screens have gotten larger, the user base has shifted into a mode where there is a little bit more trackpad and keyboard use in how many people use the device,” Federighi told Ars. “And so the stars kind of aligned to where many of the things that you traditionally do with a Mac were possible to do on an iPad for the first time and still meet iPad’s basic contract.”
On correcting some of Stage Manager’s problems
More multitasking in iPadOS 26. Credit: Apple
Apple has already tried a windowed multitasking system on modern iPads once this decade, of course, with iPadOS 16’s Stage Manager interface.
Any first crack at windowed multitasking on the iPad was going to have a steep climb. This was the first time Apple or its developers had needed to contend with truly dynamically resizable app windows in iOS or iPadOS, the first time Apple had implemented a virtual memory system on the iPad, and the first time Apple had tried true multi-monitor support. Stage Manager was in such rough shape that Apple delayed that year’s iPadOS release to keep working on it.
But the biggest problem with Stage Manager was actually that it just didn’t work on a whole bunch of iPads. You could only use it on new expensive models—if you had a new cheap model or even an older expensive model, your iPad was stuck with the older Slide Over and Split View modes that had been designed around the hardware limitations of mid-2010s iPads.
“We wanted to offer a new baseline of a totally consistent experience of what it meant to have Stage Manager,” Federighi told Ars. “And for us, that meant four simultaneous apps on the internal display and an external display with four simultaneous apps. So, eight apps running at once. And we said that’s the baseline, and that’s what it means to be Stage Manager; we didn’t want to say ‘you get Stage Manager, but you get Stage Manager-lite here or something like that. And so immediately that established a floor for how low we could go.”
Fixing that was one of the primary goals of the new windowing system.
“We decided this time: make everything we can make available,” said Federighi, “even if it has some nuances on older hardware, because we saw so much demand [for Stage Manager].”
That slight change in approach, combined with other behind-the-scenes optimizations, makes the new multitasking model more widely compatible than Stage Manager is. There are still limits on those devices—not to the number of windows you can open, but to how many of those windows can be active and up-to-date at once. And true multi-monitor support would remain the purview of the faster, more-expensive models.
“We have discovered many, many optimizations,” Federighi said. “We re-architected our windowing system and we re-architected the way that we manage background tasks, background processing, that enabled us to squeeze more out of other devices than we were able to do at the time we introduced Stage Manager.”
Stage Manager still exists in iPadOS 26, but as an optional extra multitasking mode that you have to choose to enable instead of the new windowed multitasking system. You can also choose to turn both multitasking systems off entirely, preserving the iPad’s traditional big-iPhone-for-watching-Netflix interface for the people who prefer it.
“iPad’s gonna be iPad”

However, while the new iPadOS 26 UI takes big steps toward the Mac’s interface, the company still tries to treat them as different products with different priorities. To date, that has meant no touch screens on the Mac (despite years of rumors), and it will continue to mean that there are some Mac things that the iPad will remain unable to do.
“But we’ve looked and said, as [the iPad and Mac] come together, where on the iPad the Mac idiom for doing something, like where we put the window close controls and maximize controls, what color are they—we’ve said why not, where it makes sense, use a converged design for those things so it’s familiar and comfortable,” Federighi told Ars. “But where it doesn’t make sense, iPad’s gonna be iPad.”
There will still be limitations and frustrations when trying to fit an iPad into a Mac-shaped hole in your computing setup. While tasks can run in the background, for example, Apple only allows apps to run workloads with a definitive endpoint, things like a video export or a file transfer. System agents or other apps that perform some routine on-and-off tasks continuously in the background aren’t supported. All the demos we’ve seen so far are also on new, high-end iPad hardware, and it remains to be seen how well the new features behave on low-end tablets like the 11th-generation A16 iPad, or old 2019-era hardware like the iPad Air 3.
But it does feel like Apple has finally settled on a design that might stick and that adds capability to the iPad without wrecking its simplicity for the people who still just want a big screen for reading and streaming.

Apple dropped a big batch of medium-size software updates for nearly all of its products this afternoon. The iOS 18.4, iPadOS 18.4, macOS 15.4, tvOS 18.4, and visionOS 2.4 updates are all currently available to download, and each adds a small handful of new features for their respective platforms.
A watchOS 11.4 update was also published briefly, but it’s currently unavailable.
For iPhones and iPads that support Apple Intelligence, the flagship feature in 18.4 is Priority Notifications, which attempts to separate time-sensitive or potentially important notifications from the rest of them so you can see them more easily. The update also brings along the handful of new Unicode 16.0 emoji, a separate app for managing a Vision Pro headset (similar to the companion app for the Apple Watch), and a grab bag of other fixes and minor enhancements.
The Mac picks up two major features in the Sequoia 15.4 update. Users of the Mail app now get the same (optional) automated inbox sorting that Apple introduced for iPhones and iPads in an earlier update, attempting to tame overgrown inboxes using Apple Intelligence language models.
The Mac is also getting a long-standing Quick Start setup feature from the Apple Watch, Apple TV, iPhone, and iPad. On those devices, you can activate them and sign in to your Apple ID by holding another compatible Apple phone or tablet in close proximity. Macs running the 15.4 update finally support the same feature (though it won’t work Mac-to-Mac, since a rear-facing camera is a requirement).
Apple on Tuesday patched a critical zero-day vulnerability in virtually all iPhones and iPad models it supports and said it may have been exploited in “an extremely sophisticated attack against specific targeted individuals” using older versions of iOS.
The vulnerability, tracked as CVE-2025-24201, resides in Webkit, the browser engine driving Safari and all other browsers developed for iPhones and iPads. Devices affected include the iPhone XS and later, iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and later. The vulnerability stems from a bug that wrote to out-of-bounds memory locations.
Supplementary fix
“Impact: Maliciously crafted web content may be able to break out of Web Content sandbox,” Apple wrote in a bare-bones advisory. “This is a supplementary fix for an attack that was blocked in iOS 17.2. (Apple is aware of a report that this issue may have been exploited in an extremely sophisticated attack against specific targeted individuals on versions of iOS before iOS 17.2.)”
The advisory didn’t say if the vulnerability was discovered by one of its researchers or by someone outside the company. This attribution often provides clues about who carried out the attacks and who the attacks targeted. The advisory also didn’t say when the attacks began or how long they lasted.
The update brings the latest versions of both iOS and iPadOS to 18.3.2. Users facing the biggest threat are likely those who are targets of well-funded law enforcement agencies or nation-state spies. They should install the update immediately. While there’s no indication that the vulnerability is being opportunistically exploited against a broader set of users, it’s a good practice to install updates within 36 hours of becoming available.
As is custom, Apple rolled out software updates to all its platforms at once today. All users should now have access to the public releases of iOS 18.3, macOS Sequoia 15.3, watchOS 11.3, iPadOS 15.3, tvOS 15.3, and visionOS 2.3.
Also, as usual, the iOS update is the meatiest of the bunch. Most of the changes relate to Apple Intelligence, a suite of features built on deep learning models. The first Apple Intelligence features were introduced in iOS 18, with additional ones added in iOS 18.1 and iOS 18.2
iOS 18.3 doesn’t add any significant new features to Apple Intelligence—instead, it tweaks what’s already there. Whereas Apple Intelligence was opt-in in previous OS versions, it is now on by default in iOS 18.3 on supported devices.
For the most part, that shouldn’t be a noticeable change for the majority of users, except for one thing: notification summaries. As we’ve reported, the feature that summarizes large batches of notifications using a large language model is hit-and-miss at best.
For most apps, not much has changed on that front, but Apple announced that with iOS 18.3, it’s temporarily disabling notification summaries for apps from the “News & Entertainment” category in light of criticisms by the BBC and others about how the feature was getting the substance of headlines wrong. The feature will still mess up summarizing your text messages and emails, though.
Apple says it has changed the presentation of summaries to make it clearer that they are distinct from other, non-AI generated summaries and that they are in beta and may be inaccurate.
Other updates include one to visual intelligence, a feature available on the most recent phones that gives you information on objects your camera is focused on. It can now identify more plants and animals, and you can create calendar events from flyers or posters seen in your viewfinder.
On Thursday, Apple released the first software updates for its devices since last month’s rollout of iOS 18 and macOS Sequoia.
Those who’ve been following along know that several key features that didn’t make it into the initial release of iOS 18 are expected in iOS 18.1, but that’s not the update we got on Thursday.
Rather, Apple pushed out a series of smaller updates that fixed several bugs but did not add new features. The updates are labeled iOS 18.0.1, iPadOS 18.0.1, visionOS 2.0.1, macOS Sequoia 15.0.1, and watchOS 11.0.1.
Arguably, the two most important fixes come in iPadOS 18.0.1 and iOS 18.0.1. The iPad update fixes an issue that bricked a small number of recently released iPads (those running Apple’s M4 chip). That problem caused Apple to quickly pull iPadOS 18 for those devices, so Thursday’s iPadOS 18.0.1 release is actually the first time most users of those devices will be able to run iPadOS 18.
On the iPhone side, Apple says it has addressed a bug that could sometimes cause the touchscreen to fail to register users’ fingers.

Apple’s newest iPhones and Apple Watches don’t come out until later this week, but the rumor mill is already indicating that Apple is planning a product announcement for October to refresh some of the products that didn’t get a mention at the iPhone event. Apple scheduled its release calendar similarly last year, when it announced and released new iPhones in September and then launched the first wave of M3 Macs around Halloween.
Bloomberg’s Mark Gurman believes that the event will mainly focus on the first wave of Macs with M4 processors, following the standard M4’s introduction in the iPad Pro earlier this year. As he has reported previously, he expects new MacBook Pro models with the M4 and “pro-level M4 chip options,” presumably the M4 Pro and M4 Max. He also expects an M4 version of the 24-inch iMac.
But the most interesting of the new Macs will still be the redesigned Mac mini, which hasn’t gotten an M3 update at all and has been using the same basic external design since 2010. This Mac mini is said to be closer in size to the Apple TV than the current mini, but still uses an internal power supply so that owners won’t have to wrangle a power brick. At least some of the current device’s ports will be replaced by USB-C and/or Thunderbolt ports, something that MacRumors apparently confirmed earlier today when they found a reference to an “Apple silicon Mac mini (5 ports)” in an Apple software update (some of those ports are reportedly on the front of the device, a nice Mac Studio design upgrade that I’d like to see on a new Mac mini).
The “five port” descriptor does imply that there will be another model with either more or fewer ports—Apple used similar terminology to distinguish the two- and four-port versions of some MacBook Pro models in the Intel days. The current M2 Mac mini models have fewer ports than the models with the M2 Pro chip, because the more powerful processor also has more I/O capabilities—assuming we get one Mac mini with an M4 and an upgraded model with an M4 Pro, we’d expect the Pro version to have more ports.
Gurman says that other Mac models, including the Mac Studio, Mac Pro, and MacBook Air, will see M4-series updates throughout 2025. Of those, the Mac Studio and the Mac Pro have gone the longest without an update—they’re all still using M2-series chips.
Apple is also said to be planning some new lower-end iPads for the October event—not the first time that Macs and iPads have shared billing for one of these late-fall product announcements. The $349 iPad 10 and the iPad mini have both gone over a year without any kind of hardware update; it seems likely that they’ll both get newer chips, if not significantly updated designs.
Today is the official release date for the public versions of iOS 18, iPadOS 18, macOS 15 Sequoia, and a scad of other Apple software updates, the foundation that Apple will use for Apple Intelligence and whatever other features it wants to add between now and next year’s Worldwide Developers Conference in June. But for those who value stability and reliability over new features, you may not be excited to update to a new operating system with a version number ending in “0.”
For those of you who prefer to wait for a couple of bugfix updates before installing new stuff, Apple is also releasing security-only updates for a bunch of its (now) last-generation operating systems today. The iOS 17.7, iPadOS 17.7, and macOS 14.7 updates are either available now or should be shortly, along with a security update for 2022’s macOS 13 Ventura. An updated version of Safari 18 that runs on both macOS 13 and 14 should be available soon, though as of this writing is doesn’t appear to be available yet.
Apple has historically been pretty good about providing security updates to older macOS releases—you can expect them for about two years after the operating system is replaced by a newer version. But for iOS and iPadOS, the company used to stop updating older versions entirely after releasing a new one. This changed back in 2021, when Apple decided to start providing some security-only updates to older iOS versions to help people who were worried about installing an all-new potentially buggy OS upgrade.
Eventually, iOS and iPadOS users will need to install iOS 18 and iPadOS 18 to keep getting security updates. But for the handful of older iPads that can’t run iPadOS 18, Apple will usually keep supporting those specific devices with security updates for a year or two. Apple was still providing new security updates for 2022’s iOS 16 as recently as August, keeping older devices like the iPhone 8 and the first-generation iPad Pros reasonably secure even though they were incapable of running newer operating systems.
Apple has some minor updates for all its operating systems, and the releases include iOS 17.6, iPadOS 17.6, tvOS 17.6, watchOS 10.6, and macOS Sonoma 14.6.
Apple’s notes for these updates simply say they include bug fixes, security updates, or optimizations. However, there are a few hidden features.
macOS 14.6 reportedly enables multi-display support in clamshell mode on the M3 MacBook Pro, allowing users of that device to use two external displays at once. That was already possible on the M3 Pro and M3 Max variations. Apple had previously released a similar update to bring that functionality to the M3 MacBook Air.
iOS 17.6 and iPadOS 17.6 have added a feature called Catch Up, which is targeted at sports fans who use Apple’s TV app.
The feature allows users to watch a quick sequence of highlights that have been produced so far from an in-progress Major League Soccer game before joining the live feed.
That’s about it, though. These are minor updates, and they are likely the final ones other than security hotfixes until Apple begins rolling out its annual updates, such as iOS 18 and macOS Sequoia 15, later this fall.
Those updates are expected to include several new features, though the biggest—Apple Intelligence, a suite of generative AI features—will not arrive until iOS 18.1, which was just released as a developer beta for the first time.
iOS 17.6, iPadOS 17.6, tvOS 17.6, watchOS 10.6, and macOS Sonoma 14.6 are available to download and install on all supported devices now.
Apple’s next-generation operating systems are taking their next step toward release today: Apple is issuing the first public beta builds of iOS 18, iPadOS 18, macOS 15 Sequoia, tvOS 18, and HomePod Software 18 today. Sign up for Apple’s public beta program with your Apple ID, and you’ll be able to select the public beta builds from Software Update in the Settings app.
We covered the highlights of most of these releases when they were announced during Apple’s Worldwide Developers Conference in June, including more home screen customization in iOS and iPadOS, window tiling and iPhone mirroring in macOS,RCS text messaging support across all of Apple’s platforms, and more. But Apple still isn’t ready to show off a preview of its Apple Intelligence AI features, including the text and image generation features and a revamped Siri. Many of these features are still slated for “later this summer” and will presumably be available in some form in the final releases this fall.
Most devices that can run iOS 17, iPadOS 17, and macOS 14 Sonoma will be able to update to the new versions, including owners of the last couple generations of Intel Macs. But a handful of older phones and tablets and the 2018 MacBook Air are being dropped by the new releases. The watchOS 11 update is also dropping the Series 4 and Series 5 models as well as the first-generation Apple Watch SE.
Apple is also not releasing a public beta build of VisionOS 2, the first major update to the Apple Vision Pro’s operating system. Users who want to try out new Vision Pro features ahead of time will still need to opt into the developer beta, at least for now.
Beta best practices
The first public betas are similar—if not identical—to the third developer beta builds that were released last week. Apple usually releases new developer betas of next-gen OS releases every two weeks, so we’d expect to see a fourth developer beta early next week and a second near-identical public beta build released shortly after.
Apple’s developer and public beta builds used to be more clearly delineated, with a $99-per-year developer account paywall put up between general users and the earliest, roughest preview builds. That changed last year when Apple made basic developer accounts (and beta software access) free for anyone who wanted to sign up.
Apple still issues separate developer/public beta builds, but these days it’s more of a statement about who the betas are ready for than an actual technical barrier. Developer betas are rougher and visibly unfinished, but developers likely have the extra patience and technical chops needed to deal with these issues; public betas are still unfinished and unstable, but you can at least expect most basic functionality to work fine.
Regardless of how stable these betas may or may not be, the standard warnings apply: Make a good backup of your device before updating in case you need to restore the older, more stable operating system, and don’t install beta software on mission-critical hardware that you absolutely need to work correctly in your day-to-day life. For iPhones and iPads that connect to iCloud, connecting the devices to a PC or Mac and performing a local backup (preferably an encrypted one) can be a more surefire way to make sure you keep a pre-upgrade backup around than relying on continuous iCloud backups.
