Anthropic’s New Claude Mythos Is So Good at Finding and Exploiting Vulnerabilities That They’re Not Releasing It to the Public

8 April 2026 at 15:49

Anthropic’s Frontier Red Team:

Earlier today we announced Claude Mythos Preview, a new general-purpose language model. This model performs strongly across the board, but it is strikingly capable at computer security tasks. In response, we have launched Project Glasswing, an effort to use Mythos Preview to help secure the world’s most critical software, and to prepare the industry for the practices we all will need to adopt to keep ahead of cyberattackers.

This blog post provides technical details for researchers and practitioners who want to understand exactly how we have been testing this model, and what we have found over the past month. We hope this will show why we view this as a watershed moment for security, and why we have chosen to begin a coordinated effort to reinforce the world’s cyber defenses.

Our new model is so good, it’s too dangerous to release to the public” is a message that sounds like it could be marketing hype. But it seems like it’s probably true. Examples cited by Anthropic include finding and exploiting a 27-year-old OpenBSD bug (that can crash any device running OpenBSD) and a 16-year-old bug in the widely used FFmpeg media processing library.

Adobe Diddles With Your /etc/hosts File

9 April 2026 at 20:35

“thenickdude”, on Reddit:

They’re using this to detect if you have Creative Cloud already installed when you visit on their website.

When you visit https://www.adobe.com/home, they load this image using JavaScript:

https://detect-ccd.creativecloud.adobe.com/cc.png

If the DNS entry in your hosts file is present, your browser will therefore connect to their server, so they know you have Creative Cloud installed, otherwise the load fails, which they detect.

They used to just hit http://localhost:<various ports>/cc.png which connected to your Creative Cloud app directly, but then Chrome started blocking Local Network Access, so they had to do this hosts file hack instead.

(Via Thom Holwerda at OSNews.)

They didn’t have to do this, of course. In fact, quite obviously, they definitely should not be doing this. Adobe is just a third-party developer, no better, no more trusted, no more important than any other. Imagine if every piece of software on your computer added entries to your /etc/hosts file. Madness. Adobe should be ashamed of themselves. Adobe used to be a bastion of best practices for developers to follow. Now their installer/updater is indistinguishable from malware.

MacOS Seemingly Crashes After 49 Days of Uptime — a β€˜Feature’ Perhaps Exclusive to Tahoe

9 April 2026 at 22:14

Jason Snell, writing at Six Colors:

Software developer Photon, whose product requires running a bunch of Macs to connect to iMessage, discovered a pretty major bug:

Every Mac has a hidden expiration date. After exactly 49 days, 17 hours, 2 minutes, and 47 seconds of continuous uptime, a 32-bit unsigned integer overflow in Apple’s XNU kernel freezes the internal TCP timestamp clock… ICMP (ping) keeps working. Everything else dies. The only fix most people know is a reboot.

The whole story is wild (albeit technical). Photon says they’re working on a fix, but really, this is something Apple should be working on.

If you keep track of time using milliseconds, and store that in an unsigned 32-bit integer, it overflows after 49 days, 17 hours, 2 minutes, and 47 seconds. That’s the bug.

I think this bug is new to Tahoe. If you look at Apple’s open-source XNU kernel code — e.g. lines 3,732 to 3,745 in tcp_subr.c — you can see that the lines assigning the time in milliseconds to a uint32_t variable were checked in just six months ago, whereas most of the file is five years old. Also, I personally ran my MacBook Pro — at the time, running MacOS 15.7.2 Sequoia — up to 91 days of uptime in January. I even mentioned that remarkable uptime in my annual report card, in praise of Apple’s software reliability. Apple’s pre-Tahoe reliability, that is.

I was hesitant to link to this at all because the original (unbylined) report from Photon is so hard to follow. It’s downright manic — over 3,500 words with 33 section headings (<h2> and <h3> tags), with no cohesive narrative. The bug, seemingly, is not that complicated. The whole write-up from Photon just screams “AI-generated slop” to me, and I thus hesitate even to link to Snell’s piece linking to it. But I think the bug is real, and my sympathy for everyone afflicted with MacOS 26 Tahoe is sincere. (And if I’m wrong about the post being AI slop and a human at Photon actually wrote this, I would suggest taking it easy with the cocaine.)

β˜… Let Us Learn to Show Our Friendship for a Man When He Is Alive and Not After He Is Dead

10 April 2026 at 21:29

For The New Yorker, Ronan Farrow and Andrew Marantz go deep profiling Sam Altman under the mince-no-words headline “Sam Altman May Control Our Future — Can He Be Trusted?” 16,000+ words — roughly one-third the length of The Great Gatsby — very specifically investigating Altman’s trustworthiness, particularly the details surrounding his still-hard-to-believe ouster by the OpenAI board in late 2023, only to return within a week and purge the board. The piece is long, yes, but very much worth your attention — it is both meticulously researched and sourced, and simply enjoyable to read. Altman, to his credit, was a cooperative subject, offering Farrow and Marantz numerous interviews during an investigation that Farrow says took over a year and half.

A few excerpts and comments (not in the same order they appear in the story):

1.

Yet most of the people we spoke to shared the judgment of Sutskever and Amodei: Altman has a relentless will to power that, even among industrialists who put their names on spaceships, sets him apart. “He’s unconstrained by truth,” the board member told us. “He has two traits that are almost never seen in the same person. The first is a strong desire to please people, to be liked in any given interaction. The second is almost a sociopathic lack of concern for the consequences that may come from deceiving someone.”

The board member was not the only person who, unprompted, used the word “sociopathic.” One of Altman’s batch mates in the first Y Combinator cohort was Aaron Swartz, a brilliant but troubled coder who died by suicide in 2013 and is now remembered in many tech circles as something of a sage. Not long before his death, Swartz expressed concerns about Altman to several friends. “You need to understand that Sam can never be trusted,” he told one. “He is a sociopath. He would do anything.”

A recurring theme in the piece is that colleagues who’ve worked with Altman the closest trust him the least. This bit about Aaron Swartz warning friends that Altman is a “sociopath” who “can never be trusted” is, to my knowledge, new reporting. Swartz’s opinion carries significant weight with me.1 Swartz is lionized (rightly) for his tremendous strengths, and the profoundly tragic circumstances of his martyrdom have resulted in less focus on his weaknesses. But I knew him fairly well and he led a very public life, and I’m unaware of anyone claiming he ever lied. Exaggerated? Sure. Lied? I think never.

Another central premise of the story is that while it’s axiomatic that one should want honest, trustworthy, scrupulous people in positions of leadership at any company, the nature of frontier AI models demands that the organizations developing them be led by people of extraordinary integrity. The article, to my reading, draws no firm conclusion — produces no smoking gun, as it were — regarding whether Sam Altman is generally honest / trustworthy / scrupulous. But I think it’s unambiguous that he’s not a man of great integrity.

2.

Regarding Fidji Simo, OpenAI’s other “CEO”:

Several executives connected to OpenAI have expressed ongoing reservations about Altman’s leadership and floated Fidji Simo, who was formerly the C.E.O. of Instacart and now serves as OpenAI’s C.E.O. for AGI Deployment, as a successor. Simo herself has privately said that she believes Altman may eventually step down, a person briefed on a recent discussion told us. (Simo disputes this. Instacart recently reached a settlement with the F.T.C., in which it admitted no wrongdoing but agreed to pay a sixty-million-dollar fine for alleged deceptive practices under Simo’s leadership.)

This paragraph is juicy in and of itself, with its suggestions of palace intrigue. But it’s all the more interesting in light of the fact that, post-publication of the New Yorker piece, Fidji Simo has taken an open-ended medical leave from OpenAI. If we run with the theory that Altman is untrustworthy (the entire thesis of Farrow and Marantz’s story), and that Simo is also untrustworthy (based on the fraudulent scams she ran while CEO of Instacart, along with her running the Facebook app at Meta before that), we’d be foolish not to at least consider the possibility that her medical leave is a cover story for Altman squeezing Simo out after catching on to her angling to replace him atop OpenAI. The last thing OpenAI needs is more leadership dirty laundry aired in public, so, rather than fire her, maybe Altman let her leave gracefully under the guise of a relapse of her POTS symptoms?

Simo’s LinkedIn profile lists her in two active roles: CEO of “AGI deployment” at OpenAI, and co-founder of ChronicleBio (“building the largest biological data platform to power AI-driven therapies for complex chronic conditions”). If my spitball theory is right, she’ll announce in a few months that after recuperating from her POTS relapse, the experience has left her seeing the urgent need to direct her energy at ChronicleBio. Or perhaps my theory is all wet, and Simo and Altman have a sound partnership founded on genuine trust, and she’ll soon be back in the saddle at OpenAI overseeing the deployment of AGI (which, to be clear, doesn’t yet exist2). But regardless of whether the Altman-Simo relationship remains cemented or is in the midst of dissolving, it raises serious questions why — if Altman is a man of integrity who believes that OpenAI is a company whose nature demands leaders of especially high integrity — he would hire the Instacart CEO who spearheaded bait-and-switch consumer scams that all came right out of the playbook for unscrupulous car salesmen.

3.

Regarding Altman’s stint as CEO at Y Combinator, and his eventual, somewhat ambiguous, departure, Farrow and Marantz write:

By 2018, several Y.C. partners were so frustrated with Altman’s behavior that they approached [Y Combinator founder Paul] Graham to complain. Graham and Jessica Livingston, his wife and a Y.C. founder, apparently had a frank conversation with Altman. Afterward, Graham started telling people that although Altman had agreed to leave the company, he was resisting in practice. Altman told some Y.C. partners that he would resign as president but become chairman instead. In May, 2019, a blog post announcing that Y.C. had a new president came with an asterisk: “Sam is transitioning to Chairman of YC.” A few months later, the post was edited to read “Sam Altman stepped away from any formal position at YC”; after that, the phrase was removed entirely. Nevertheless, as recently as 2021, a Securities and Exchange Commission filing listed Altman as the chairman of Y Combinator. (Altman says that he wasn’t aware of this until much later.)

Altman has maintained over the years, both in public and in recent depositions, that he was never fired from Y.C., and he told us that he did not resist leaving. Graham has tweeted that “we didn’t want him to leave, just to choose” between Y.C. and OpenAI. In a statement, Graham told us, “We didn’t have the legal power to fire anyone. All we could do was apply moral pressure.” In private, though, he has been unambiguous that Altman was removed because of Y.C. partners’ mistrust. This account of Altman’s time at Y Combinator is based on discussions with several Y.C. founders and partners, in addition to contemporaneous materials, all of which indicate that the parting was not entirely mutual. On one occasion, Graham told Y.C. colleagues that, prior to his removal, “Sam had been lying to us all the time.”

Graham responded to this on Twitter/X thus:

Since there’s yet another article claiming that we “removed” Sam because partners distrusted him, no, we didn’t. It’s not because I want to defend Sam that I keep insisting on this. It’s because it’s so annoying to read false accounts of my own actions.

Which tweet includes a link to a 2024 tweet containing the full statement Farrow and Marantz reference, which reads:

People have been claiming YC fired Sam Altman. That’s not true. Here’s what actually happened. For several years he was running both YC and OpenAI, but when OpenAI announced that it was going to have a for-profit subsidiary and that Sam was going to be the CEO, we (specifically Jessica) told him that if he was going to work full-time on OpenAI, we should find someone else to run YC, and he agreed. If he’d said that he was going to find someone else to be CEO of OpenAI so that he could focus 100% on YC, we’d have been fine with that too. We didn’t want him to leave, just to choose one or the other.

Graham is standing behind Altman publicly, but I don’t think The New Yorker piece mischaracterized his 2024 statement about Altman’s departure from Y Combinator. Regarding the quote sourced to anonymous “Y.C. colleagues” that he told them “Sam had been lying to us all the time”, Graham tweeted:

I remember having a conversation after Sam resigned with a YC partner who said he and some other partners had been unhappy with how Sam had been running YC. I told him Sam had told us that all the partners were happy, so he was either out of touch or lying to us.

And, emphasizing that this remark was specifically in the context of how happy Y Combinator’s partners were under Altman’s leadership of YC, Graham tweets:

Every YC president tends to tell us the partners are happy. Sam’s successor did too, and he was mistaken too. Saying the partners are unhappy amounts to saying you’re doing a bad job, and no one wants to admit or even see that.

Seems obvious in retrospect, but we’ve now learned we should ask the partners themselves. (And they are indeed now happy.)

I would characterize Graham’s tweets re: Altman this week as emphasizing only that Altman was not fired or otherwise forced from YC, and could have stayed as CEO at YC if he’d found another CEO for OpenAI. But for all of Graham’s elucidating engagement on Twitter/X this week regarding this story, he’s dancing around the core question of the Farrow/Marantz investigation, the one right there in The New Yorker’s headline: Can Sam Altman be trusted? “We didn’t ‘remove’ Sam Altman” and “We didn’t want him to leave” are not the same things as saying, say, “I think Sam Altman is honest and trustworthy” or “Sam Altman is a man of integrity”. If Paul Graham were to say such things, clearly and unambiguously, those remarks would carry tremendous weight. But — rather conspicuously to my eyes — he’s not saying such things.

4.

From the second half of the same paragraph quoted above, that started with Aaron Swartz’s warnings about Altman:

Multiple senior executives at Microsoft said that, despite Nadella’s long-standing loyalty, the company’s relationship with Altman has become fraught. “He has misrepresented, distorted, renegotiated, reneged on agreements,” one said. Earlier this year, OpenAI reaffirmed Microsoft as the exclusive cloud provider for its “stateless” — or memoryless — models. That day, it announced a fifty-billion-dollar deal making Amazon the exclusive reseller of its enterprise platform for A.I. agents. While reselling is permitted, Microsoft executives argue OpenAI’s plan could collide with Microsoft’s exclusivity. (OpenAI maintains that the Amazon deal will not violate the earlier contract; a Microsoft representative said the company is “confident that OpenAI understands and respects” its legal obligations.) The senior executive at Microsoft said, of Altman, “I think there’s a small but real chance he’s eventually remembered as a Bernie Madoff- or Sam Bankman-Fried-level scammer.”

The most successful scams — the ones that last longest and grow largest — are ones with an actual product at the heart. Scams with no actual there there go bust quickly. The Bankman-Fried FTX scandal blew up quickly because FTX never offered anything of actual value. Bernie Madoff, though, had a long career, because much of his firm’s business was legitimate. It wasn’t only the Ponzi scheme, which is what enabled Madoff to keep the Ponzi scheme going for two decades.

But the better comparison to OpenAI — if that “small but real chance” comes true — might be Enron. Enron was a real company that built and owned a very real pipeline and energy infrastructure business. ChatGPT and Codex are very real, very impressive technologies. Enron’s operations were real, but the story they told to investors was a sham. OpenAI’s technology is undeniably real and blazing the frontier of AI. It’s the financial story Altman has structured that seems alarmingly circular.


  1. In a 2005 Y Combinator “class photo”, Altman and Swartz are standing next to each other. Despite the fact that Altman was sporting a reasonable number of popped polo collars (zero), Swartz was clearly the better-dressed of the two.* ↩︎
    * Aaron would’ve loved this footnote. Christ, I miss him.

  2. With rare exceptions, I continue to think it’s a sign of deep C-suite dysfunction when a company has multiple “CEOs”. When it actually works — like at Netflix, with co-CEOs Ted Sarandos and Greg Peters (and previously, Sarandos and Reed Hastings before Hastings’s retirement in 2023) — the co-CEOs are genuine partners, and neither reports to the other. There is generally only one director of a movie, but there are exceptions, who are frequently siblings (e.g. the Coens, the Wachowskis, the Russos). A football team only has one head coach. The defensive coordinator is the “defensive coordinator”, not the “head coach of defense”. It’s obvious that Fidji Simo reports to Sam Altman, and thus isn’t the “CEO” of anything at OpenAI. But OpenAI does have applications, and surely is creating more of them, so being in charge of applications is being in charge of something real. By any reasonable definition, AGI has not yet been achieved, and many top AI experts continue to question whether LLM technology will ever result in AGI. So Simo changing her title to (or Altman changing her title to) “CEO of AGI deployment” is akin to changing her title to “CEO of ghost busting” in terms of its literal practical responsibility. ↩︎︎

My thanks to Typotheque for sponsoring last week at DF to promote Zed, their incredible new font superfamily. Zed is a type system that was developed with one question in mind: what do readers actually need? Not what looks good in a type specimen, but what works for the widest possible range of readers. Typotheque tested Zed with visually impaired patients at a French ophthalmology hospital and found that Zed Text outperformed Helvetica in terms of reading speed across all patient groups. Designed from scratch to perform different functions, it comes in two optical versions — Text and Display — with four variable axes and support for 547 languages, including endangered ones.

Zed is extremely practical, both in terms of its extraordinarily broad language support and the stylistic variations available via its adjustable width, weight, roundness, and slant. It even offers Braille characters and an icon font. But Zed is also simply beautiful. It’s a font family and type system that exemplifies the belief that rich accessibility and pure aesthetic appeal are not at odds.

When you purchase a license for Zed, you’re buying it directly from the designers. It’s just lovely, and you should check it out. (Don’t miss the short introductory video, either.)

Viktor Orban Loses Election in Hungary, Concedes Defeat, Congratulates Opposition Winners

12 April 2026 at 21:59

The New York Times:

In a surprisingly early and gracious concession speech in Budapest, Mr. Orban congratulated the opposition saying, “The responsibility and opportunity to govern were not given to us.” But, he also made a vow: “We are not giving up. Never, never, never.”

His defeat paves the way for Peter Magyar, a former Orban loyalist and the leader of the main opposition party, to take over as Hungary’s prime minister once the newly elected Parliament meets.

Political Wire:

Orban said the “election results, although not complete, are understandable and clear. They are painful for us but unequivocal.”

There we have it: Viktor Orban — a MAGA star and general anti-democratic corrupt dirtbag — is a better and bigger man than Donald Trump, who still refuses to concede the 2020 election that he unequivocally lost to Joe Biden.

MacOS Tip: Enable the Zoom β€˜Peek’ Gesture

13 April 2026 at 17:43

Marcin Wichary, at Unsung:

Go to Settings > Accessibility > Zoom, and then turn on “Use scroll gesture with modifier keys to zoom.”

Then, at any moment, you can hold Control and swipe with two fingers (or use a scroll wheel) up or down to zoom the entire screen.

I’d also recommend turning off “Smooth images” under “Advanced…” so you see individual pixels better.

This is one of the very best MacOS tips. No third-party software. Built into MacOS for several (many?) years now. Incredibly useful.

But I had no idea it existed until last June at WWDC. It was Monday, after the morning keynote and just before the afternoon State of the Union. Beautiful sunny day at Apple Park. I ran into my old friend Cabel Sasser, and, maniac that he is, he’d already installed the first Tahoe developer beta on his MacBook Pro. So I sat next to him and we started examining the UI changes in detail. And Cabel was zooming in and out instantaneously. I was like, “Whoa, how are you doing that?” And Cabel was like, “You don’t know about the Accessibility Zoom gesture? Here, let me show you!” And my mind was blown. Cabel emphasized the importance of going into the “Advanced…” dialog to turn off “Smooth images”, and I agree. This is a fantastic feature, but Apple has the default setting wrong for smoothing (a.k.a. blurring) the zoomed image. I honestly can’t imagine why anyone would want the zoomed image blurred.

Anyway, then we both laughed ourselves silly and made ourselves a little queasy examining, in detail, just how bad the Tahoe UI was. And I thought to myself, I need to post this as a tip on Daring Fireball.

Well, it took 10 months, but Wichary posting it on Unsung reminded me that I never posted about it here. [Update: Actually...] Turn this on, start using it, and you’ll find yourself using it every day if you care about design details.

Bonus tip: Subscribe to Wichary’s Unsung in your RSS reader. He’s only been posting there since early December, and it quickly became one of my favorite blogs in the world. One of those blogs where I’m excited every time I see there’s a new post. I would read a post from Wichary describing what it’s like to watch paint dry, because I know he’d only write about it if he noticed something interesting and nuanced. Because he’s only been writing Unsung for a few months, you can catch up on the whole thing.

John Martellaro, RIP

Bryan Chaffin, two weeks ago:

John Martellaro was good man. He was not only a better man than me, he was one of the best people I knew. It is with a heavy heart that I tell you Mr. Martellaro passed away today.

He rose to the rank of Captain in the U.S. Air Force, and he was a NASA scientist. He worked for years at Apple, and most importantly to me, he was a columnist and the voice of reason and humanity at The Mac Observer. He wrote SciFi and a variety of tech columns for several other Mac sites, too.

Michael Tsai:

He wrote for many Mac publications. Just his author page at TMO has 83 pages of article summaries.

One of Martellaro’s columns I most remember was one I linked to in January 2010, “How Apple Does Controlled Leaks”:

Often Apple has a need to let information out, unofficially. The company has been doing that for years, and it helps preserve Apple’s consistent, official reputation for never talking about unreleased products. I know, because when I was a Senior Marketing Manager at Apple, I was instructed to do some controlled leaks.

The way it works is that a senior exec will come in and say, “We need to release this specific information. John, do you have a trusted friend at a major outlet? If so, call him/her and have a conversation. Idly mention this information and suggest that if it were published, that would be nice. No e-mails!”

Inexplicably, the original piece is no longer hosted at The Mac Observer, but thankfully the Internet Archive has it. What’s interesting about this particular leak, to The Wall Street Journal, is that it came just three weeks before the introduction of the first iPad, and this was the story that pegged the price of the “new multimedia tablet device” at “about $1,000”.

The actual starting price of the iPad was $500, which made the purpose of the leak — if indeed it was a deliberate strategy from Apple leadership — pretty obvious. A $500 price looks pretty good if everyone is expecting a $500 price. But a $500 price is cause for celebration if everyone is expecting it to cost $1,000. It’s a way of under-promising and over-delivering without ever having promised a damn thing.

Another one worth revisiting is this post from December 2011, where I linked to a Martellaro column in which he declared that the success of the Amazon Kindle Fire necessitated that Apple build a 7-inch iPad. “Noted for future claim chowder,” I wrote. Well, Apple debuted the iPad Mini in October 2012.

I never did revisit Martellaro’s accurate prediction. Rest in peace, and enjoy the posthumous Being Right Point.

Tahoe Nitpick of the Day: β€˜Reduce Transparency’ Makes Layers Harder to See, Not Easier

Tahoe looks like Huawei’s rushed rip-off of what Tahoe should be.

  • Memory, They Say, Is the First Thing to Go
    Welp, turns out I wrote an entire post about the Control-scroll zoom-in-and-out feature all the way back in 2006, when it was a new feature in Mac OS X 10.4 Tiger. Somehow, between 2006 and last year, I completely forgot about it. I don’t think it helps that the settings moved from the Mouse panel to the Zoom sub-section inside Accessibility. But I’ve used it so much in the last year, since rediscovering it, that I can’t believe I ever forgot it. Anyway, after I posted about i

Apple Frames 4

Federico Viticci:

Today, I’m very happy to introduce Apple Frames 4, a major update to my shortcut for framing screenshots taken on Apple devices with official Apple product bezels. Apple Frames 4 is a complete rethinking of the shortcut that is noticeably faster, updated to support all the latest Apple devices, and designed to support even more personalization options. For the first time ever, Apple Frames supports multiple colors for each device, allowing you to mix and match different colored bezels for each framed screenshot; it also supports proportional scaling when merging screenshots from different Apple devices.

But that’s not all. In addition to an updated shortcut, I’m also releasing the Apple Frames CLI, an open source command-line utility that lets developers and tinkerers automate the process of framing screenshots directly from the Mac’s Terminal. And there’s more: the Apple Frames CLI is also designed to work with AI agents, and it comes with a Claude Code/Codex skill that lets coding agents take care of framing dozens or even hundreds of screenshots in just a few seconds, from any folder on your Mac.

David Smith:

I’ve been using this recently and it is super helpful. I must frame dozens of screenshots a week and always looking for more efficient workflows for it.

  • Steven Soderbergh Twice Pitched James Bond Projects
    The Playlist: The first pitch, he said, goes back to 2008, and it was already pretty radical by Bond standards. “I had pitched in 2008 the idea to Barbara Broccoli of a parallel franchise,” Soderbergh said. “Set in the ’60s, R-rated, violent, sexy. Fictional backstory to real historical events, different actor, different universe.” [...] That version was designed to open up a different, more lo-fi, stripped-down, and cost-effective way of making Bond movies, b
     

Steven Soderbergh Twice Pitched James Bond Projects

The Playlist:

The first pitch, he said, goes back to 2008, and it was already pretty radical by Bond standards. “I had pitched in 2008 the idea to Barbara Broccoli of a parallel franchise,” Soderbergh said. “Set in the ’60s, R-rated, violent, sexy. Fictional backstory to real historical events, different actor, different universe.” [...]

That version was designed to open up a different, more lo-fi, stripped-down, and cost-effective way of making Bond movies, but not a replacement for them. “[It would be] cheaply made, where you get people like me, who are interested in that approach to do one of these things,” Soderbergh explained. “It’s just another lane that exists totally separate from the normal Bond movies.”

Broccoli and company, he said, were at least open enough to hear it out. “They were intrigued,” Soderbergh said. “But didn’t move forward.”

This hurts — it hurts to ponder what could have been.

Glider Is Back in the Mac App Store

John Calhoun, on Bluesky (and also a new blog):

I re-made Glider some years back for MacOS/iOS. It broke at some point (perhaps an Apple change for Retina displays?) so I pulled it from the App Store.

(Claude looked at the code — found some minor coordinate issues. Thanks!) Glider Classic for MacOS is back on.

11 years between version 1.0.4 and yesterday’s 1.1 looks like a long time. But when you consider that Calhoun shipped the original Glider back in 1988, that puts things in perspective. If you’ve never used Glider, it remains an all-time great procrastination utility. There aren’t many Mac apps still in development from that era.

(Calhoun, you will recall, in addition to making a slew of early Mac games, went on to a long career as an engineer at Apple, where, amongst other things, he worked on Preview for many years. He now makes cool personal projects like SystemSix and this excellent model of the Pan Am Orion that was in some old movie.)

Richard Moss’s 2010 Interview With John Calhoun on the Origins of Glider

Richard Moss, back in 2010:

John Calhoun’s Glider games hold a special place in the history of Mac gaming, acting almost as an icon of the platform through much of the 1990s. They spawned a hugely dedicated fan base, which produced a ridiculous amount of original content both for and about Glider — especially Glider 4 and Glider PRO, the later versions.

I caught up with Calhoun over email recently, and quizzed him on the origins and development of the series. This is the first part of that interview. Read on to discover where the idea for Glider originated, how the game came to exist, and how it dramatically altered Calhoun’s future.

Here’s the updated working link to part 2 of the interview, and to Moss’s feature story, “Dreaming of a Thousand-Room House: The History and Making of Glider”. The links to those pages in part 1 of the interview are both out of date and result in 404s.

Moss, of course, is the author of the excellent book The Secret History of Mac Gaming, which features an entire chapter on Calhoun and Glider, aptly titled “Quintessentially Mac”.
