Steam Announces Steam Link for Apple Vision Pro and Releases Beta Version

The gaming ecosystem on visionOS continues to grow, this time with the announcement that Steam Link is coming to the platform. The official app will allow users to wirelessly stream games in 2D from Steam on their local Macs and PCs to their Vision Pros. According to the company, the app can stream games at up to 4K resolution and includes an adjustable, curved panoramic view. A TestFlight beta is now available for those who want to test the app before its public release.

Steam’s stature in the PC gaming market cannot be understated, so opening the platform up to the Vision Pro is a huge boon for gaming on the device. Of course, one would hope to see VR streaming support come with time, but official support even for 2D gaming is a big step.

Between an official Steam client, 4K cloud game streaming from NVIDIA GeForce NOW, console remote play via Portal, local OpenVR game streaming with ALVR, HDMI input over UVC via the Developer Strap, and native titles from Apple Arcade and the App Store, the variety of games available for Vision Pro users to play is getting larger by the day. There’s lots to be excited about in the world of visionOS gaming these days.

LunarWall: Shuffle Moon Photos from Artemis II On Your Lock Screen or Mac Desktop

LunarWall for iOS.

LunarWall for iOS.

I’ve been staring at my Lock Screen and macOS desktop a lot this week. Not because of John’s iMessage notifications or the weird handhelds we share in the NPC group thread – because of the Moon. Specifically, because of photos taken by Orion as it swung within 4,067 miles of the lunar surface during the Artemis II flyby a couple of days ago. Yesterday, NASA published an official gallery of images from the flyby, and I immediately knew what I had to do.

LunarWall is a simple shortcut that picks a random image from a curated set of 23 photos pulled from NASA’s Artemis II Lunar Flyby gallery and sets it as your wallpaper. That’s it! Each time you run it, you get a different photo. The way this shortcut works, NASA’s images aren’t re-hosted or saved anywhere on your computer: the LunarWall shortcut fetches each image directly from NASA’s CDN and passes it to the ‘Set Wallpaper’ action, which is configured to automatically crop images to fit on mobile devices, blurs the wallpaper for the iOS/iPadOS Home Screen, and uses the original widescreen images at high resolutions on macOS.

Claude Mythos Preview Will Only Secure Part of the Internet

Yesterday, Anthropic announced Claude Mythos Preview, a new general-purpose model that it says is exceptionally good at finding security vulnerabilities in code. In fact, the model is so good that Anthropic has decided not to release Mythos Preview to the general public. Instead, it’s being released to a select group of companies that control OSes and other critical software.

Anthropic found thousands of vulnerabilities across every major OS and web browser with Mythos Preview, but used these three examples to illustrate their severity:

  • Mythos Preview found a 27-year-old vulnerability in OpenBSD—which has a reputation as one of the most security-hardened operating systems in the world and is used to run firewalls and other critical infrastructure. The vulnerability allowed an attacker to remotely crash any machine running the operating system just by connecting to it;
  • It also discovered a 16-year-old vulnerability in FFmpeg—which is used by innumerable pieces of software to encode and decode video—in a line of code that automated testing tools had hit five million times without ever catching the problem;
  • The model autonomously found and chained together several vulnerabilities in the Linux kernel—the software that runs most of the world’s servers—to allow an attacker to escalate from ordinary user access to complete control of the machine.

A lengthy Frontier Red Team report brings the receipts for security researchers with an in-depth look at what Mythos Preview uncovered and the step change that the new model represents over Opus 4.6:

For example, Opus 4.6 turned the vulnerabilities it had found in Mozilla’s Firefox 147 JavaScript engine—all patched in Firefox 148—into JavaScript shell exploits only two times out of several hundred attempts. We re-ran this experiment as a benchmark for Mythos Preview, which developed working exploits 181 times, and achieved register control on 29 more.

As part of a test, Mythos Preview also managed to escape its sandboxed environment, message the researcher conducing the test, and then, outside the parameters of the test, posted about the exploit online.

The idea behind Project Glasswing, whose participants include Amazon Web Services, Anthropic, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto Networks, is to give them a head start at securing their systems before similar models emerge and are exploited for cyberattacks. If Mythos Preview’s capabilities are as Anthropic makes them out to be, this seems like the right approach. However, I do worry that with time, it could lead to a two-tier Internet where big tech companies operate in relative security thanks to tools like Mythos Preview, while those without access are left to swim with the sharks.

How Can Everybody Hate Their Weather App When There Are So Many Great Choices?→

Twitter clients may have been a design playground in the early days of the App Store, but it’s weather apps that have carried the torch. That’s because the developers of weather apps have to simultaneously contend with a vast amount of data and a wide variety of user preferences.

Last week, for The New Yorker, Kyle Chayka profiled Acme Weather, the new weather app from the team behind Dark Sky that I recently reviewed.

The problem with weather apps, as Brian Mueller, who was interviewed for the story, puts it is that:

“Everybody wants their own weather app,” Mueller told me. An Angeleno may care more about air quality, for instance, whereas a Bostonian wants to know the chance of snow. Carrot’s imperfect solution is to allow users to customize their own display, choosing which information to foreground, against a backdrop of chaotic animations and snarky jokes (“The temperature is low, but my disdain for you is even lower”). Hello Weather separates various stats—on UV or wind—into separate onscreen tiles. Acme’s answer, the most elegant of the three, is to show a minimum of information based on what matters most in a given moment.

Chayka clearly prefers Acme’s approach, which overlays weather predictions from multiple forecasters accompanied by a short narrative summary. I like Acme Weather’s, too, but Chayka was too quick to dismiss CARROT Weather and Hello Weather’s approaches. The fact that all three, plus other top tier weather apps like Mercury Weather can co-exist proves Mueller’s point that everyone wants their own weather app. I’d argue the real problem is that most users haven’t found the right weather app for them or aren’t willing to pay for a better one. Acme Weather is an excellent app, but it’s just one among many great choices, and as users, we’re fortunate that there’s room for all of them.

Roadtripping with ChatGPT Voice Mode

On Saturday, my wife Jennifer and I drove to Blowing Rock, a quaint little town in the Blue Ridge Mountains. We’d been there once before, but didn’t know the town well, so as we headed west I poked at the ChatGPT icon on my dashboard to give the app’s new CarPlay integration a try. I asked:

What activities would you recommend for a day trip to Blowing Rock, North Carolina?

What I got back was a short but good list of highlights including a hike, a visit to the Blowing Rock cliffside overlook, a few restaurants, a coffee shop, and some local shops. It was similar to a list of activities I’d looked up before we left using Claude. So far, so good.

I switched back to Apple Maps and was thinking I probably wouldn’t use ChatGPT in my car very often, but that it could come in handy for similar requests, when things got a little creepy. I explained to Jennifer that ChatGPT’s CarPlay feature was new, and I had been meaning to check it out all week. Then, just as I’d said I thought it had done a pretty good job, a voice interrupted. It was ChatGPT’s voice mode saying it was glad I liked it.

You see, just like a phone call doesn’t drop when you switch apps in CarPlay, neither does ChatGPT. I supposed I should have anticipated that the mic would remain live, but I didn’t. Nor did I notice the End button in the corner of the screen; I was driving, not studying the app’s UI.

I take it as a positive sign that I didn’t expect ChatGPT to follow me back to Apple Maps. I treat chatbots like I do any app. Give it some input, and you get an output. Close the app, and you’re done. It’s not my little robot buddy. It’s a tool like any other app.

Of course, that’s not how the voice modes of these chatbots are designed to work. Chats are meant to be an engaging back and forth. But having ChatGPT jump in on our one-on-one conversation while driving down the highway was too much. Suddenly, it felt like something else was in the car eavesdropping on us.

The experience was a good lesson in the balancing of utility and social norms around AI tools. Useful as they can be in some situations, their developers need to be more mindful of user expectations and provide better cues about how they work to avoid uncomfortable surprises. The recommendations we got from ChatGPT were good, but I also don’t expect it will get a second chance on our family road trips anytime soon.

On This Day: My New Favorite Way to Revisit Old Photos

If you’ve followed my work for long, you’ve probably picked up on the fact that I’m a nostalgic person. I love to relive old memories, share old stories, and look at old pictures. It’s just the way I am.

That’s why I’m a big fan of Apple’s Memories feature built into the Photos app. You’re telling me my phone can deliver a slideshow of great pictures from my library anytime I want, and with a cheesy soundtrack to boot? Count me in. Photos is an amazing app for resurfacing pictures that otherwise might have been forgotten.

But there’s always been one feature I felt was missing from Photos: a roundup of every picture you’ve taken on a particular date in past years.1 While automatically-generated memories are great, I don’t want to limit my nostalgic photo viewing to the pictures my phone thinks are the best. I want a way to review all my pictures from the past, and an “on this day” approach is one that works well in other contexts, like journaling. Why not photos?

Enter a new app for the iPhone and iPad from developer Florian Grossmann fittingly called On This Day. It’s a simple, nicely-designed way to revisit photos you took on a particular date in previous years, and it’s quickly become a go-to for me. In fact, On This Day is now a part of my regular morning routine because it enables me to quickly do something I love to do: look at old photos and reminisce about fun moments, amazing trips, and milestones in the lives of myself and my loved ones.

The app’s UI is a simple grid of pictures, much like the one you’re used to seeing in Photos, except instead of showing every picture in your library, the app only includes images and videos from a particular date, which is displayed at the bottom center of the screen. The grid is broken up into years by headings that stick to the top of the screen as you scroll, ensuring you always know which year you’re browsing. By default, scrolling down the screen moves you backwards in time towards older photos, though you can reverse this order in the app’s settings.

Tapping on a picture will open it in a full-screen view that not only allows you to see the photo in finer detail, but also to learn more about it and act on it. I like how much information and functionality is packed into this simple screen. At the top of the screen is the photo’s time and date (as well as a count of how many photos you took on that particular day), and at the bottom of the screen, the app shows the location of where the photo was taken on a map. If you prefer to view your photo without these overlays, a single tap will dismiss them, and you can swipe left and right to move between photos in the full-screen view.

In the upper-right corner of this view, there are four buttons: Info, Favorite, Share, and Delete. Favoriting a picture in On This Day adds it to your Favorites collection in Photos. This can come in handy since the app doesn’t have the ability to actually open an image in Photos; the developer says this is due to technical limitations of the Photos app itself. But at the very least, you can favorite a photo to refer to later in the Photos app as a workaround.

The Photo Details pane includes a variety of technical information about a photo.

The Photo Details pane includes a variety of technical information about a photo.

If you want to dig into the technical details of a picture, you can tap the Info button to open the Photo Details pane. There, you’ll find the photo’s resolution, camera and lens information, focal length, and more. It’s great to have this data close at hand when reviewing photos, especially if you want to see which iPhone you were using at a particular time in the past.

This core functionality is all I’ve ever wanted out of this kind of tool. It’s fast, it’s easy to use, and it’s designed well to help me find the photos I want and then get out of the way so I can fully enjoy them. It fits right in with current iOS aesthetics, as well, with Liquid Glass headings and buttons that blend naturally with your photos and adapt to the varying content behind them. The experience of reviewing pictures in On This Day is simply great, and I enjoy opening the app every day to see what memories it has to offer.

If you want to review photos from other days, you can do so by tapping the arrow buttons on either side of the date at the bottom of the screen or by tapping the date itself to open up a calendar to select from. Once you’ve navigated away from the current date, the app will offer a Today button above the calendar to quickly get you back to your starting point.

The app’s settings include a number of customization options, too. There, you can adjust the density of the photo grid, change how images are ordered, disable the optional streak count, and schedule notifications to remind you to review your photos each day. On This Day also offers the unique ability to decide what content the app sends when you share a photo; you can include the date in various formats, customized text, or no text at all. For me, part of the fun of looking at old photos is sending them to other people, so I appreciate the option to customize what gets shared.

Finally, On This Day also offers widgets in small, medium, large, and extra-large sizes so you can see photos from past years right on your Home Screen. You can adjust how many pictures appear within a widget, and photos can be displayed in full color even if, like me, you’re a user of the Clear or Tinted appearance for app icons.

This is the sort of app that I’ve been wanting on my devices for a long time, and the fact that it’s been made with such care and attention to detail just makes the experience of using it that much sweeter. I love revisiting old photos in the app every day, and if you’re the type of person who’s built up years of pictures in your library and delights in having them resurfaced for you, I think you’ll enjoy it, too. I recommend giving it a try.

On This Day is available on the App Store for iPhone and iPad as a free download, and the iPad version can also be run on the Vision Pro. The app displays photos from the past three years for free. You can unlock all past years and the app’s full range of customization options with a one-time payment of $4.99 or a $0.99/month subscription.

  1. You can technically achieve this by entering the current date (e.g., “April 7”) in the search bar and even automate this search with Shortcuts, as cleverly demonstrated to me recently by reader Miles Jefford. Personally, though, I think Photos should just include an On This Day collection. ↩

Apple Arcade (April 2)

Apple Arcade is debuting a trio of games this month:

Dredge+

First off is Dredge+ a Lovecraftian fishing adventure game. Federico and I had the pleasure of interviewing two members of the Dredge team at WWDC last year and were impressed with the thought and care that went into the Apple Design Award-winning game. The Arcade version includes all of Dredge DLC content that has been released, too. If you’re an Arcade subscriber and haven’t played Dredge yet, check out Dredge+ on Arcade, because it’s a treat.

Unpacking+

Unpacking, which won an Apple App Store Cultural Impact Award in 2023, is another game worth checking out this month. It’s a low-key puzzle game that revolves around removing possessions from boxes and arranging them in your home, which is surprisingly relaxing.
