John Giannandrea’s Retirement From Apple Announced

Today Apple announced the retirement of John Giannandrea, the company’s senior vice president for Machine Learning and AI Strategy. Giannandrea will remain at Apple as an advisor until next spring.

News of Giannandrea’s retirement was paired with an announcement that Apple has hired Amar Subramanya as vice president of AI. Subramanya, who worked at Microsoft since this past summer, previously worked at Google for 16 years on projects including the company’s Gemini Assistant. Subramanya will take the lead on Apple Foundation Models, ML research, and AI Safety and Evaluation, while other areas of Giannandrea’s work will be inherited by Sabih Khan and Eddy Cue.

Apple CEO Tim Cook thanked Giannandrea for his tenure at the company:

We are thankful for the role John played in building and advancing our AI work, helping Apple continue to innovate and enrich the lives of our users. AI has long been central to Apple’s strategy, and we are pleased to welcome Amar to Craig’s leadership team and to bring his extraordinary AI expertise to Apple. In addition to growing his leadership team and AI responsibilities with Amar’s joining, Craig has been instrumental in driving our AI efforts, including overseeing our work to bring a more personalized Siri to users next year.

Given the troubled history of Apple’s AI efforts, the retirement of Giannandrea isn’t surprising. It will be interesting to see if Subramanya settles into his new role given the frequency with which top AI talent tends to turn over in the tech industry.

Why is ChatGPT for Mac So Good?→

Great post by Allen Pike on the importance of a great app experience for modern LLMs, which I recently wrote about. He opens with this line, which is a new axiom I’m going to reuse extensively:

A model is only as useful as its applications.

And on ChatGPT for Mac specifically:

The app does a good job of following the platform conventions on Mac. That means buttons, text fields, and menus behave as they do in other Mac apps. While ChatGPT is imperfect on both Mac and web, both platforms have the finish you would expect from a daily-use tool.

[…]

It’s easier to get a polished app with native APIs, but at a certain scale separate apps make it hard to rapidly iterate a complex enterprise product while keeping it in sync on each platform, while also meeting your service and customer obligations. So for a consumer-facing app like ChatGPT or the no-modifier Copilot, it’s easier to go native. For companies that are, at their core, selling to enterprises, you get Electron apps.

I don’t hate Electron as much as others in our community, but I can’t deny that ChatGPT is one of the nicest AI apps for Mac I’ve used. The other is the recently updated BoltAI. And they’re both native Mac apps.

The AI App Experience Matters More Than Benchmarks Now

Different experiences with app connectors in Claude, Perplexity, and ChatGPT.

Different experiences with app connectors in Claude, Perplexity, and ChatGPT.

I was catching up on different articles after the release of Claude Opus 4.5 earlier this week, and this part from Simon Willison’s blog post about it stood out to me:

I’m not saying the new model isn’t an improvement on Sonnet 4.5—but I can’t say with confidence that the challenges I posed it were able to identify a meaningful difference in capabilities between the two.

This represents a growing problem for me. My favorite moments in AI are when a new model gives me the ability to do something that simply wasn’t possible before. In the past these have felt a lot more obvious, but today it’s often very difficult to find concrete examples that differentiate the new generation of models from their predecessors.

This is something that I’ve felt every few weeks (with each new model release from the major AI labs) over the past year: if you’re really plugged into this ecosystem, it can be hard to spot meaningful differences between major models on a release-by-release basis. That’s not to say that real progress in intelligence, knowledge, or tool-calling isn’t being made: benchmarks and evaluations performed by established organizations tell a clear story. At the same time, it’s also worth keeping in mind that more companies these days may be optimizing their models for benchmarks to come out on top and, more importantly, that the vast majority of folks don’t have a suite of personal benchmarks to evaluate different models for their workflows. Simon Willison thinks that people who use AI for work should create personalized test suites, which is something I’m going to consider for prompts that I use frequently. I also feel like Ethan Mollick’s advice of picking a reasoning model and checking in every few months to reassess AI progress is probably the best strategy for most people who don’t want to tweak their AI workflows every other week.

Just the Best: MacStories’ Black Friday 2025 Picks

Black Friday deals started very early this year, and we’ve covered a lot of ground on the MacStories Deals Mastodon and Bluesky accounts since publishing our Early Black Friday Picks. A lot of those deals are ongoing, so it’s worth revisiting that story as you start your holiday shopping in earnest.

However, today, I wanted to hit the highlights of what we’ve covered over the past week on MacStories Deals and add some new deals to the mix that you probably haven’t seen yet, so buckle up, it’s time to go shopping.

MacStories Pixel Icons

All three MacStories Pixel Icon sets are 40% off until Monday, December 1.

Two of the icon sets are specially-designed for Shortcuts. We’ve all been there. You work hard on a shortcut and want to give it the perfect icon, only to realize that Apple doesn’t offer what you want in the Shortcuts app. The MacStories Pixel Icons fill that gap with an extensive set of painstakingly hand-crafted icons with multiple color options created by MacStories’ long-time designer, Silvia Gatta. We also offer a set of Perspective icons that are perfect for OmniFocus Pro and other uses.

Visit our dedicated MacStories Pixel page today to preview all three icon sets and purchase them for 40% off until Monday, December 1.

Apple Hardware

There are a lot of Black Friday deals on Apple hardware, but most of them are good, not great. I’m picky, so I’m only going to focus on just the great deals.

One of the best deals on Apple hardware during Black Friday is the M4 13” MacBook Air with 16GB of memory and 256GB of storage. If you want more memory or storage than that, you’ll have to settle for a smaller percentage discount, but even with more memory and more storage, you’re still doing better than any other deal this year. The 15” M4 MacBook Air with 16GB of memory and a 256GB SSD is a good deal, too.

Among the many iPad deals, the best is on the 128GB iPad mini with an A17 Pro chip. I’ve had a mini since they were released and love it. The size makes it an excellent reading and video-watching device.

AirPods 4 are also heavily discounted for Black Friday. Apple’s most affordable wireless earbuds come with active noise cancellation and without. The model with no active noise cancellation slightly edges out the model with ANC as far as the discounts are concerned, but both models are a bargain.

However, the very best deals available from Apple in terms of the percentage discount are a 4-pack of AirTags and the Apple Pencil Pro. If you need either, now is the perfect time to buy them.

Smart Home

The holiday season is a great time to catch up on projects and start new ones. For me, that’s often tuning up my smart home setup and setting up some new devices thanks to Black Friday sales. Here are the best ones I’ve seen:

Aqara already makes some of the most affordable smart home devices out there, so you really can’t go wrong with their Black Friday deals. One of my favorites is the FP2 Presence Sensor. It’s far more sophisticated than a simple motion sensor. To start with, it can tell when you’ve left a room, which motion sensors can’t do. I’ve used an FP2 Sensor in my office to control lighting for a couple of years, wrote about it for Club members, and have been really happy with it.

Other great deals from Aqara include its U100 Smart Lock that works with Apple Home Key and HomeKit, the Aqara M3 Home Hub that I recently set up at home and love, and 4MP Camera Hub G5 Pro, an outdoor HomeKit camera that I reviewed earlier this year.

My Aqara 4MP Camera Hub G5 Pro is paired with an Ecobee Smart Video Doorbell, which is also on sale for Black Friday. I’ve used various Ecobee smart home products for years and have never been disappointed. The same goes for its smart doorbell. I’ve had it installed for over a year, and it’s been reliable despite facing the sun on some very hot summer days.

Black Friday is also a great time to buy a robot vacuum and mop. There are lots of deals, but the model I’ve tested for the past couple of months and love is the Narwal Freo X10 Pro. It handles vacuuming and mopping, navigating via LiDAR and does an excellent job compared to other robot vacuums I’ve tried. I’ll be reviewing the Freo X10 Pro about it soon, but now’s the time to get it at a steep discount.

Festivitas Brings Fresh Whimsy to Your Mac, iPhone, and iPad for the Holiday Season

Last year, Simon Støvring released Festivitas, a Mac app that lets you string holiday lights from your menu bar and across the top of your Dock. This year, Simon is back with an update to the Mac app and a new version for the iPhone and iPad.

The default set of lights consists of traditional multi-colored bulbs that blink on and off as you use your Mac. That’s the set I use the most, but Festivitas offers many more options. You can control the lights’ opacity, whether they appear along both the menu bar and the Dock or just one of them, and the colors of the lights and the cable from which they hang. You also have more than a dozen light styles to choose from, including round holiday lights, bats, clovers, eggs, stars, hearts, snowflakes, cocktail glasses, beer mugs, “2026,” “WWDC,” and more, covering a wide variety of holidays and festive events. Plus, you can control how the lights blink. It’s a lot, but it’s also just plain fun to tweak everything to suit your tastes.

This year, the Mac app adds a virtual snowstorm that you can start from the app’s settings or menu bar item. It’s a great addition that looks amazing against a dark backdrop like the Obsidian theme I often use to write. A fun touch is that the snowflakes avoid your pointer, and you can adjust the sensitivity of this feature in settings. You can also use your pointer to push around the lights hanging from the menu bar, which is handy for those times when they obscure Safari’s menu bar or other content.

The snow is lovely. I highly recommend pairing it with the Animal Crossing Snowy Day soundtrack on Nintendo Music. It’s an incredibly peaceful and relaxing combination.

Festivitas supports Shortcuts, too. Simon has created some fun example automations that you’ll find in the app’s settings to do things like turning on the snowstorm when snow is forecast and activating your lights when you play music.

Festivitas on iPhone.

Festivitas on iPhone.

New this year is a Festivitas app for the iPhone and iPad. The app lets you build small, medium, and large widgets to place on your Home Screen. You can either frame a photo with twinkling lights or create a transparent-style widget so the lights frame an element of your Home Screen. I love that the lights framing the photos are animated, an effect I know isn’t easy to do with a widget. You can also add text and make other adjustments to each widget.

Festivitas isn’t going to help you get more done. In fact, it might even slow you down a little bit, and maybe that’s the point. Taking a moment to enjoy the app’s lights and be mesmerized by the falling snow is a good reminder to slow down a little and have some fun.

Festivitas for the Mac is available directly from the app’s website for any price you want to name between $3.99 and $9.99. The iPhone and iPad version is a free download on the App Store with a range of in-app purchases from $3.99 to $9.99 to create a similar name-your-price system.
