You have to wonder how meaningful this news is in 2024, but macOS 15.0 Sequoia running on either Apple Silicon or Intel processors is now UNIX 03-certified. The UNIX 03 Product Standard is the mark for systems conforming to Version 3 of the Single UNIX Specification. It is a significantly enhanced version of the UNIX 98 Product Standard. The mandatory enhancements include alignment with ISO/IEC 9989:1999 C Programming Language, IEEE Std 1003.1-2001 and ISO/IEC 9945:2002. This Product Standard includes the following mandatory Product Standards: Internationalized System Calls and Libraries Extended V3,Commands and Utilities V4, C Language V2, and Internationalized Terminal Interfaces. ↫ UNIX 03 page The questionable usefulness of this news stems from a variety of factors. The UNIX 03 specification hails from the before time of 2002, when UNIX-proper still had some footholds in the market and being a UNIX meant something to the industry. These days, Linux has pretty much taken over the traditional UNIX market, and UNIX certification seems to have all but lost its value. Only one operating system can boast to conform to the latest UNIX specification – AIX is UNIX V7 and 03-certified – while macOS and HP-UX are only UNIX 03-certified. OpenWare, UnixWare, and z/OS only conform to even older standards. On top of all this, it seems being UNIX-certified by The Open Group feels a lot like a pay-to-play scheme, making it unlikely that community efforts like, say, FreeBSD, Debian, or similarly popular server operating systems could ever achieve UNIX-certification even if they wanted to. This makes the whole UNIX-certification world feel more like the dying vestiges of a job security program than something meaningful for an operating system to aspire to. In any even, you can now write a program that compiles and runs on all two UNIX 03-certified operating systems, as long as it only uses POSIX APIs.
The widely–reported “foo is requesting to bypass the system private window picker and directly access your screen and audio” prompt in Sequoia (which Apple has moved from daily to weekly to now monthly) can be disabled by quitting the app, setting the system date far into the future, opening and using the affected app to trigger the nag, clicking “Allow For One Month”, then restoring the correct date. ↫ tinyapps.org blog Or, and this is a bit of a radical idea, you could use an operating system that doesn’t infantalise its users.
We all know about the Desktop Publishing revolution that the first Macs and their PostScript LaserWriter printers brought in the late 1980s, but many have now forgotten the Desktop Video revolution that followed in the next decade. At its heart was support for multimedia in Apple’s QuickTime. QuickTime isn’t a single piece of software, or even an API in Classic Mac OS, but a whole architecture to support almost any media format you could conceive of. It defines container and file formats for multiple media types, forming the basis for the MPEG-4 standard, extensible encoding and decoding of a wide variety of media using Codecs, and more. ↫ Howard Oakley As a Windows users before I switched to the Mac somewhere in 2003 or 2004 or so, I mostly associated QuickTime with an annoying piece of crapware I sometimes had to install to watch videos, despite my Windows installation being perfectly capable of playing a whole slew of video codecs just fine. To make matters worse, Apple eventually started forcing Windows users to also install their auto-update tool that ran in the background, which would occasionally just… Install stuff without your permission. Of course, QuickTime was a whole lot more than that, especially on the Mac, where it was simply a core technology of the Mac operating system and the name of the built-in video player. It also served as underpinnings for a whole slew of related technologies, from movie editors like iMovie to the QuickTime streaming tools included in Mac OS X Server, so odds are that somehow, somewhere, you’ve used QuickTime in your life time. I’m not entirely ashamed to admit I had to check if QuickTime was still part of macOS today – I haven’t actively used macOS since, I think, the Snow Leopard days in 2009 – but it obviously has been sunset quite a while ago in favour of AVFoundation, which macOS still uses today.
It’s one of the most pervasive common wisdoms shared all over the web, no matter where you go – it’s one of those things everybody seems to universally agree on: Chrome will absolutely devastate your battery life on the Mac, and you should really be using Safari, because Apple’s special integration magic pixie dust sprinkles ensures Safari sips instead of gulps electricity. Whether you read random forum posters, Apple PR spokespeople, or Apple’s own executives on stage during events, this wisdom is hard to escape. Is it true, though? Well, Matt Birchler decided to do something entirely revolutionary and entirely unheard of: a benchmark. Back in the olden days of yore, we would run benchmarks to test the claims from companies and their PR departments, and Birchler decided to dust off this old technique and develop a routine to put the Chrome battery claims to the test. After 3 days of continuous testing on a freshly installed 14” MacBook Pro with an M2 Pro processor and 16 GB RAM running the latest stable releases of both browsers, Birchler came to some interesting conclusions. In my 3-hour tests, Safari consumed 18.67% of my battery each time on average, and Chrome averaged 17.33% battery drain. That works out to about 9% less battery drain from Chrome than Safari. Yes, you read that right, I found Chrome was easier on my battery than Safari. While I did experience some variability in each 3 hour test run, Chrome came out on top in 5 of the 6 direct comparisons. ↫ Matt Birchler His methodology seems quite sound and a good representation of what most laptop users will use their browser for: YouTube, social media, a few news websites, and editing a Google Doc, in a 20 minute loop that was repeated for three hours per test. Multiple of these three hour tests were then ran to counter variability. I highly doubt using different websites will radically change the results, but I obviously am curious to see a similar test ran on Windows and Linux, x86 and ARM, for a more complete picture that goes beyond just the Mac. Conventional wisdom is sometimes wrong, and I think we have a classic case of that here. While there may have been a time in the past where Chrome on the Mac devastated battery life, it seems Chrome and Chromium engineers have closed the gap, and in some cases even beat Safari. Now, this doesn’t mean everybody should rush and switch to Chrome, since there are countless other reasons to use Safari over Chrome other than supposed battery life advantages. With Apple PR arguing that alternative browser engines should not be allowed on iOS because Chrome would devastate iOS’ battery life, tests like these are more important than ever, and I hope we’re going to see more of them. Tech media always just seems to copy/paste whatever manufacturers and corporations claim without so much as a hint of skepticism, and this benchmark highlights the dangers of doing so, in case you didn’t already know believing corporations was a terribly idea.
When you launch an app, macOS connects to Apple’s OCSP service to check whether the app’s Developer ID code signing certificate has been revoked by Apple. In November 2020, Apple’s OCSP service experienced a mass outage, preventing Mac users worldwide from launching apps. In response and remedy to this outage, Apple made several explicit promises to Mac users in a support document, which can still be seen in a Wayback Machine archive from September 24, 2023. ↫ Jeff Johnson One of the explicit promises Apple made was that it would allow macOS users to turn off phoning home to Cupertino every time you launch an application on macOS. It’s four years later now, and this promise has not been kept – Apple still does not allow you to turn off phoning home. In fact, it turns out that last year, Apple scrubbed this promise from all of its documentation, hoping we’re all going to forget about it. In other words, Apple is never going to allow its macOS users to stop the operating system from phoning home to Cupertino every time you launch an application. Even though the boiling frog story is nonsensical, it’s apt here. More and more Apple is limiting its users’ control over macOS, locking it down to a point where you’re not really the owner of your computer anymore. Stuff like this gives me the creeps.
Speaking of an operating system for toddlers: Apple is eliminating the option to Control-click to open Mac software that is not correctly signed or notarized in macOS Sequoia. To install apps that Gatekeeper blocks, users will need to open up System Settings and go to the Privacy and Security section to “review security information” before being able to run the software. ↫ Juli Clover at MacRumors On a related note, I’ve got an exclusive photo of the next MacBook Pro.
With macOS Sequoia this fall, using apps that need access to screen recording permissions will become a little bit more tedious. Apple is rolling out a change that will require you to give explicit permission on a weekly basis to these types of apps, and every time you reboot your Mac. If you’ve been using the macOS Sequoia beta this summer in conjunction with a third-party screenshot or screen recording app, you’ve likely been prompted multiple times to continue allowing that app access to your screen. While many speculated this could be a bug, that’s not the case. ↫ Chance Miller Everybody is making comparisons to Windows Vista, but I don’t think that’s fair at all. Windows Vista suffered from an avelanche of permission dialogs because the wider Windows application, driver, and peripheral ecosystem was not at all used to the security boundaries present in Windows NT being enforced. Vista was the first consumer-focused version of Windows that started doing this, and after a difficult transition period, the flood of dialogs settled down, and for a long time now you can blame Windows for a lot of things, but it’s definitely not throwing up more permission dialogs than, say, an average desktop-focused Linux distribution. In other words, Vista’s UAC dialogs were a desperately necessary evil, an adjustment period the Windows ecosystem simply had to go through, and Windows as a whole is better off for it today. This, however, is different. This is Apple having such a low opinion of its users, and such a deep disregard for basic usability and computer ownership, that it feels entirely okay with bothering its users with weekly – or more, if you tend to reboot – nag dialogs for applications the user has already properly given permission to. I don’t have any real issues with a reminder or permission dialog upon first launching a newly installed screen recording application – or when an exisiting application gains this functionality in an update – but nagging users weekly is just beyond insanity. More and more it feels like macOS is becoming an operating system for toddlers – or at least, that’s how Apple seems to view its users.
The Macintosh was intended to be different in many ways. One of them was its file system, which was designed for each file to consist of two forks, one a regular data fork as in normal file systems, the other a structured database of resources, the resource fork. Resources came to be used to store a lot of standard structured data, such as the specifications for and contents of alerts and dialogs, menus, collections of text strings, keyboard definitions and layouts, icons, windows, fonts, and chunks of code to be used by apps. You could extend the types of resource supported by means of a template, itself stored as a resource, so developers could define new resource types appropriate to their own apps. ↫ Howard Oakley And using ResEdit, a tool developed by Apple, you could manipulate the various resources to your heart’s content. I never used the classic Mac OS when it was current, and only play with it as a retro platform every now and then, so I ever used ResEdit when it was the cool thing to do. Looking back, though, and learning more about it, it seems like just another awesome capability that Apple lost along the way towards modern Apple. Perhaps I should load up on my old Macs and see with my own eyes what I can do with ResEdit.
Howard Oakley has written an interesting history of secure enclaves on the Mac, and when he touches upon “exclaves”, a new concept that doesn’t have a proper term yet, he mentions something interesting. While an enclave is a territory entirely surrounded by the territory of another state, an exclave is an isolated fragment of a state that exists separately from the main part of that state. Although exclave isn’t a term normally used in computing, macOS 14.4 introduced three kernel extensions concerned with exclaves. They seem to have appeared first in iOS 17, where they’re thought to code domains isolated from the kernel that protect key functions in macOS even when the kernel becomes compromised. This in turn suggests that Apple is in the process of refactoring the kernel into a central micro-kernel with protected exclaves. This has yet to be examined in Sequoia. ↫ Howard Oakley I’m not going to add too much here since I’m not well-versed enough in the world of macOS to add anything meaningful, but I do think it’s an interesting theory worth looking into by people who posses far more knowledge about this topic than I do.
noTunes is a macOS application that will prevent iTunes or Apple Music from launching. Simply launch the noTunes app and iTunes/Music will no longer be able to launch. For example, when bluetooth headphones reconnect. You can toggle the apps functionality via the menu bar icon with a simple left click. ↫ noTunes GitHub page Apparently, this is such a common complaint that an application had to be made just to gain some semblance of control over what some people still refer to as “their” computer. For both macOS and Windows, there’s a giant industry – you can’t really call it a cottage industry anymore at this point – of tools, applications, and fixes just to deal with or avoid all the user-hostile, anti-choice garbage Apple and Microsoft shove into their respective operating systems. As a Linux user – and recent OpenBSD convert – I find this absolutely wild. Following any Apple podcast, or reading any Windows website, makes it so clear just how many hoops these people have to jump through and how many weirdly-shaped holes they have to contort into just to be able to gain some vague semblance of ownership of their own hardware. I’m not judging – we all have areas in our lives where we do this, they just differ from person to person – but it’s still confronting to see it so clearly, all the time.
After several days testing the latest Express 1M2 enclosure from OWC, I have changed my recommendations for the best external SSDs. Previously I had chosen the relatively reliable Thunderbolt 3 up to 3 GB/s, even though few drives ever seemed capable of achieving that up to. If you’re still needing good performance with an Intel Mac, that makes sense. But if you need best performance with an Apple silicon Mac, you’re far better off with a high-quality USB 40Gbps enclosure such as OWC’s Express 1M2, which should reliably return over 3 GB/s even through a compatible hub. I much prefer the word over to up to. ↫ Howard Oakley If you have an Apple Silicon Mac, and you’re looking for an external drive – this is some good advice to follow.
This is a contender for the World Record for Feature Creep Side Project. It is pretty high in the contender list as it’s a bolt on to another contender for the World Record for Feature Creep Side Project (the MII Apple //e emulator). It is a library that duplicate a lot of a Macintosh Classic “Toolbox” APIs. It is not a complete implementation, but it is enough to make a few simple applications, also, all the bits I needed for the MII emulator. ↫ libmui GitHub page This is absolutely wild.
About a year ago I came across the Previous emulator – it appeared to be a faithful simulation of the NeXT hardware and thus capable of running NeXTStep. While including it in Infinite Mac would be scope-creep, NeXT’s legacy is in many ways more relevant to today’s macOS than classic Mac OS. It also helped that it’s under active development by its original creator (see the epic thread in the NeXT Computers forums), and thus a modern, living codebase. Previous is the fifth emulator that I’ve ported to WebAssembly/Emscripten and the Infinite Mac runtime, and it’s gotten easier. As I’m doing this work, I’m developing more and more empathy for those doing Mac game ports – some things are really easy and others become yak shaves due to the unintended consequences of choices made by the original developers. Previous is available on multiple platforms and has good abstractions, so overall it was a pretty pleasant experience. ↫ Mihai Parparita By porting previous to WebAssembly/Emscripten, Infinite Mac now offers access to a whole slew of NeXTSTEP releases, from the earliest known release to the last one from 1997. There’s also a ton of applications added to make the experience feel more realistic. This makes Infinite Mac even more useful than it already was, ensuring it’s one of the best and easiest ways to experience old macOS and now NeXTSTEP releases through virtual machines (real ones, this time), available in your browser. I’ll be spending some time with these new additions for sure, since I’ve very little experience with NeXTSTEP other than whatever I vicariously gleamed through Steven Troughton-Smith‘s toots on the subject over the years. Mihai Parparita is doing incredibly important work through Infinite Mac, and he deserves credit and praise for all he’s doing here.
Seven years ago, on 27 March 2017, Apple introduced one of the most fundamental changes in its operating systems since Mac OS X 10.0 Cheetah was released 16 years earlier. On that day, those who updated iOS to version 10.3 had their iPhone’s storage silently converted to the first release of Apple File System, APFS. Six months later, with the release of macOS 10.13 High Sierra on 25 September, Mac users followed suit. ↫ Howard Oakley The migration from HFS+ to APFS is still an amazing feat for Apple to have pulled off. Hundreds of millions devices converted from one filesystem to another, and barely anyone noticed – no matter how you look at it, that’s an impressive achievement, and the engineers who made it possible deserve all the praise they’re getting.
It’s true that latest macOS 14 (Sonoma) still supports the latest generations of Intel Macs and it’s very likely that at least one or two major versions will still be compatible. But there’s one particular development that is de-facto killing off the Hackintosh scene. In Sonoma, Apple has completely removed all traces of driver support for their oldest WiFi/Bt cards, namely various Broadcom cards that they last used in 2012/13 iMac / MacBook models. Those Mac models are not supported by macOS for few years now thus it’s not surprising the drivers are being removed. Most likely reason is that Apple is moving drivers away from .kext (Kernel Extensions) to .dext (DriverKit) thus cleaning up obsolete and unused code from macOS. They did the same with Ethernet drivers in Ventura. ↫ Aleksandar Vacić Everybody, especially the small but active Hackintosh community itself, knew full well the writing was on the wall the day Apple switched to ARM, and we’re seeing the first signs of the impending end of the community. Sure, enough people will remain who are interested in building Hackintoshes using older, unsupported versions of macOS, kind of like retrocomputing, but the days of running the latest macOS release on non-Apple hardware are coming to an end. As a fun side note, this old OSNews article I wrote in 2009 is one of the most-visited articles on our site of all time. Hackintoshes were way, way more popular than people gave them credit for.
I recently bought a Macbook because more and more people are asking me how to use Nix in certain situations under MacOS. In this article, we walk through installing Nix on MacOS and see how pleasant the experience is these days. After that, we show how to go declarative on MacOS with nix-darwin to enable compilation for Linux and Intel Macs, as well as some other nice features. ↫ Jacek Galowicz You can’t click on a single link without tripping over people talking about nix.
We may have been using APFS for nearly seven years, but some of its features remain thoroughly opaque. On Christmas Day, I posed the puzzle of 60 TB of snapshots being removed from a 2 TB disk. While we all accept that may be “technically correct”, for ordinary users it makes no sense. Suggestions that they should be “educated” miss the point that the Finder has to be accessible to all users, whether or not they have a degree in Computer Science. If my eleven year-old granddaughter can’t make sense of it, then the Finder is a failure. Today I turn to another thorny issue raised by the ingenuity of APFS: the size of its special file types, sparse and ‘clone’ files. As usual, I start with a practical demonstration. ↫ Howard Oakley I feel like I should ring a little bell while posting a link to this article.
Running macOS virtual machines (VMs) on Apple silicon Macs may not seem popular, but it has long been one of Apple’s important goals. Yet, if you do use a virtualiser on an M-series Mac, you’ll know how different it is from those that virtualise macOS and other operating systems on Intel Macs. This article explains why virtualisation is so important, and how it has become so different. ↫ Howard Oakley Excellent read, as always from Howard Oakley.
So what can you do with it? Well, let’s first address the elephant in the room – the internet is still lousy on OS 9. Despite Cameron Kaiser’s genius effort put into his Classilla browser project, he’s pretty much squeezed every ounce of usability from the now 20+ year old underlying networking frameworks. A lot of websites still render “ok” in the browser, but most of the modern web will simply cause it to spit back an error. Also, file sharing with other machines on your network takes a bit more forethought these days as OS 9’s implementation of AppleTalk will only work with OS X versions up to 10.4 Tiger. In Mac OS X 10.5 (Leopard) and later, AppleTalk will not function at all without some difficult technical workarounds, so a “bridge” Mac is generally recommended (for those not familiar with that term – bridge Macs are machines that can handle both legacy and modern technologies and can be networked between both old and new hardware). It is also possible to wring out a bit more usability by setting up a web proxy such as macHTTP and running a small Netatalk server on one of your modern Macs (this is something I’d like to feature in the future). ↫ Adam Goff at Low End Mac Running Mac OS 9 today has become somewhat of a rite of passage for retrocomputing and operating system nerds (…2006), and every few years a new article about the experience makes the rounds. For good reason, too – OS 9 is fun, quirky, has tons of software to play around with, and still looks and feels great.
Even if you’ve used the Mac for decades, I suspect you have never fully understood the Fn key. Not helping is the fact that Apple sometimes calls it the Function key, but all Mac keyboards already have 12 or more numbered F-for-Function keys! The Fn key first appeared in 1998 in the PowerBook G3 Series (Wallstreet) and has become a fixture in the lower-left corner of laptop keyboards ever since. The Fn key migrated to standalone keyboards only in 2007 with the release of the Apple Keyboard with Numeric Keypad, where it occupies a spot between the Delete key and the Home key. On Apple’s compact desktop keyboards, it reverts to the lower-left corner. ↫ Adam Engst at TibBITS This article made me wonder when the Fn key first appeared, but searching for it leads to a lot of SEO spam that is clearly all wrong. As the article notes, Apple first introduced it in 1998, and IBM already it in on the monochrome ThinkPad 300 in 1992. It’s much older than that, though; the IBM PC Convertible from 1986 also had one, as did the IBM PCjr from 1984. At this point I’m starting to think it was actually a fairly common key, but with the explosion of IBM compatibles in the early ’80s it’s basically impossible to check them all, and, of course, there’s the possibility it may have existed on earlier systems, or third-party keyboards long lost to time. This would be an interesting mystery to solve.
