So far in this series, I have looked in broad terms at how the CPU cores in Apple silicon chips work, and how they use frequency control and two types of core to deliver high performance with low power and energy use. As I hinted previously, their design also relies on specialist processing units and co-processors, the subject of this article. Howard Oakley Another excellent read from Howard Oakley.
With the second beta of iOS 17.4, Apple disabled much of the functionality of Progressive Web Apps (PWAs) in the European Union. There was some speculation that it could be a temporary change or a bug related to some of the updates to the app ecosystem in Europe, but Apple has confirmed that PWAs were intentionally removed and won’t be returning. Juli Clover at MacRumors When users in the European Union install iOS 17.4, all functionality regarding progressive web apps will be removed from iOS. This means that when you pin a PWA on your iOS home screen, instead of it opening ‘like an application’, so without any browser chrome but with additional other odds and ends to make it feel more like a native application, it’ll just open inside the full browser instead. It’s typical Apple behaviour – vindictive and petty. Their stated reasoning – it was too hard and too much work to implement this for engines other than WebKit – is a bunch of utter nonsense, since Apple had no issues with developing like 600 new APIs and a whole bunch of new complex frameworks and administrative layers just to support their malicious DMA compliance to ensure they wouldn’t lose a single cent of protection money when a developer wants to distribute an application outside of the App Store. PWAs were the only way you could get an application-like experience on your iPhone from something not controlled, owned, and monetised by Apple, so it had to go to force developers to choose either of Apple’s new, maliciously DMA compliant monetised distribution options in the EU. Every time this company does anything, it’s just… Slimy, scummy, sleazy, and anti-user.
A number of reviews for Apple’s new VR headset have been published, but the only one I think is worth reading is, surprisingly, the one published by The Verge. Both the written and video review are excellent, and go into every possible little detail of the new device. Nilay Patel concludes: The basic gist is that the Vision Pro is simply cumbersome and unpleasant to use, exactly what many people have been suspecting since the day it was unveiled. I’ve been asking a very simple question on Mastodon nobody has been able to answer yet: is there anything you do on your phone, laptop, or desktop, that the Vision Pro can do better, easier, quicker? Now that the reviews are here, not even the people using it can provide an answer. And think about that last point in the list above. It’s a private computer that’s always looking at your hands.
In order to comply with the EU’s Digital Markets Act, Apple has announced a set of sweeping changes to iOS and the App Store in the European Union. First and foremost, starting with iOS 17.4, users in the European Union will be able to download and install applications from outside of the App Store. On top of that, alternative application stores will become possible as well. When a developer submits an application to Apple, the developer can choose to distribute the application through the App Store, alternative application stores, or both. Apple will not charge a commission on installations from outside the App Store, and it will also allow alternative payment processors, over which Apple will also not charge any additional fees. Apple will, however, charge something called a “Core Technology Fee”. Under the new terms, apps distributed through the App Store which choose to use an alternative payment system will pay a 17 percent commission (rather than 30 percent) on digital goods and services. This commission rate falls to 10 percent for any apps that currently qualify for Apple’s reduced “small business” rate. The additional 3 percent fee then applies for developers who choose to use Apple’s payment processing system. The company is also introducing a new type of fee for particularly popular apps. The new Core Technology Fee will charge developers EUR0.50 (around 54 cents) per annual app install; however, this fee only kicks in after a million annual installs in the EU. Apple estimates that over 99 percent of developers will either “reduce or maintain the fees they owe to Apple” under the new business terms and that “less that 1 percent” of developers would pay a core technology fee. Jon Porter at The Verge Overall, developers in the EU will be paying a lot less to Apple than developers in the US and elsewhere, while also gaining more options of distributing their applications outside of the App Store. I’m already seeing some serious rumblings in Apple developer circles over on Mastodon, where US-based developers are not happy these serious cost reductions will only apply to EU developers. The only kink in the cable is this “Core Technology Fee”, though, as the total bill for that nebulous cost can balloon quickly. Apple will still check applications outside of the App Store for safety, security, and privacy, though, with a system very similar to how macOS handles applications outside of the Mac App Store right now through a new – to iOS – notarisation system. This notarisation will not check applications for quality (because as we all know, the App Store is a beacon of quality) or content (hello emulators!). Another major change coming to iOS is the availability of browsers other than Safari. Right now, even if you think you’re using an alternative, non-Safari browser on iOS, you’re really just using a skin on top of a hobbled version of Safari. In the EU, starting with iOS 17.4, non-WebKit browser engines like Firefox’ Gecko or Chrome’s Blink can come to iOS, and live as equal citizens on your iOS device. Furthermore, NFS on iOS will be opening up in Europe, giving European users the ability to use services other than Apple Pay and Wallet with NFC, and even set them as default. Apple is also allowing game streaming services to come to iOS, and this change happens to be available worldwide instead of being restricted to just the EU. These are sweeping changes to how iOS and the App Store works, but much to the chagrin of US-based users and developers in my Mastodon timeline and elsewhere, they’re exclusive to the European Union. It’s unclear if Americans can import EU devices to gain access to these new features, or if they need EU-based Apple IDs. Let the grey market provide.
Apple yesterday released iOS and iPadOS 17.3 as well as watchOS 10.3, tvOS 17.3, and macOS Sonoma 14.3 for all supported devices. iOS 17.3 primarily adds collaborative playlists in Apple Music, and what Apple calls “Stolen Device Protection.” Collaborative playlists have been on a bit of a journey; they were promised as part of iOS 17, then added in the beta of iOS 17.2, but removed before that update went live. Now they’re finally reaching all users. When enabled, Stolen Device Protection requires Face ID or Touch ID authentication “with no passcode fallback” for some sensitive actions on the phone. Samuel Axon at Ars Technica This last feature is something you should probably turn on right away, as it serves as a reply to Joanna Stern’s investigation into an apparently common way iPhones would get stolen to gain access to users’ Apple accounts.
Chinese authorities recently said they’re using an advanced encryption attack to de-anonymize users of AirDrop in an effort to crack down on citizens who use the Apple file-sharing feature to mass-distribute content that’s outlawed in that country. According to a 2022 report from The New York Times, activists have used AirDrop to distribute scathing critiques of the Communist Party of China to nearby iPhone users in subway trains and stations and other public venues. A document one protester sent in October of that year called General Secretary Xi Jinping a “despotic traitor.” A few months later, with the release of iOS 16.1.1, the AirDrop users in China found that the “everyone” configuration, the setting that makes files available to all other users nearby, automatically reset to the more contacts-only setting. Apple has yet to acknowledge the move. Critics continue to see it as a concession Apple CEO Tim Cook made to Chinese authorities. Dan Goodin at Ars Technica The most damning aspect of this story is that Apple has been aware of this vulnerability in AirDrop since 2019, and has not addressed it in any way. The use of AirDrop by dissidents in China to spread critique of the Chinese government has been well-known, so it’s not entirely unreasonable to conclude that Apple has been weary of closing this security vulnerability in order to not offend China – as further evidenced by the sudden changes to AirDrop as mentioned above. What’s going to be interesting now is what Apple is going to do about this. Are they going to finally address this security hole, and thereby risking offending China? Will it fix the hole, but only in non-totalitarian countries? Will it just leave it open? Whatever they do, they’ll end up offending someone.
Today, Apple pushed out the public releases of iOS 17.2, iPadOS 17.2, macOS Sonoma 14.2, watchOS 10.2, and tvOS 17.2. iOS 17.2 and iPadOS 17.2’s flagship feature is the new Journal app, which Apple teased when it first introduced iOS 17 earlier. The app mimics several existing popular journaling apps in the App Store from third-party developers but leverages data from your Photos, workouts, and other Apple apps to make journaling suggestions. Other features include the ability to tap a “catch-up arrow” to scroll to the first missed message in a conversation in Messages, the ability to take spatial video photos for later viewing on Vision Pro, and several tweaks and additions to the Weather app. Samuel Axon for Ars Technica Makers of journalling applications for iOS are not going to be in a good mood today, I reckon.
Evaluating the performance of CPUs with identical cores is relatively straightforward, and they’re easy to compare using single- and multi-core benchmarks. When there are two different types of core, one designed primarily for energy efficiency (E), the other for maximum performance (P), traditional benchmarks can readily mislead. Multi-core results are dominated by the ratio of P to E cores, and variable frequency confounds further. In this series of articles, I set out to disentangle these when comparing core performance between Apple’s original M1 Pro and its third-generation M3 Pro chips. This first article explains why and how I am investigating this, and shows overall results for performance and power use under a range of loads. Articles like these will help you make an informed decision about whether or not your workloads can benefit from moving from an M1/M2 to an M3.
After I wrote about the possibility of programmable Mac ROM SIMMs in Quadras a couple of months ago, I suspected that there had been a way for developers at Apple in the 68k Mac era to reflash the ROM in their Macs during development, just like BIOS updates on PCs. The reason I believed this is because the ROM SIMM socket in the Quadras brought out pins for 12V (VPP) and write enable (/WE). I had verified that the write enable pin was going into the memory controller chip in several Mac models, so I was pretty confident that in-system programming was possible. As luck would have it, multiple people pointed out to me that an Apple internal utility used for ROM flashing had been uploaded to the Macintosh Garden. It was recovered from a prototype PowerBook 520 purchased in 2020. Of course, I had to download this utility and figure out how it works. I honestly cannot believe it’s taken this long for such a tool to become available one way or the other. Classic Macs are incredibly popular in the retro community, and being able to reflash the ROMs like this is incredibly useful. It took some work and disassembly, but Doug Brown got it working.
If you read the initial reviews of Apple’s new M3-based Macs, you’d be forgiven for thinking little had changed in their CPU cores, apart from a rejigging of numbers and an increase in the maximum frequency of their P cores. As my MacBook Pro 16-inch M3 Pro arrived three days early, this article presents a tentative first look at what has changed in their CPU cores, and from that, how you might choose the right chip for your next Apple silicon Mac. Like Apple, I’m going to make comparison between M1 and M3 chips, as in most respects discussed here, M2 CPU cores didn’t change as much from those in the M1, and I’ve had and tested four different M1 models. As the introduction suggests, there’s more here than many seem to think.
The European Union making tech better for everyone. We’ll have to wait and see if supporting RCS will be enough to prevent the EU from requiring Apple open up iMessage.
However, there was a secret weapon hidden in ANS AIX most of us at the time never knew about. Built-in to the operating system was a fully Unix-native AppleTalk stack and support for receiving and sending Apple Events, surfaced in the form of Apple’s disk administration tools and AppleShare. But Apple had a much more expansive vision for this feature: full server-client “symbiotic” applications that could do their number-crunching on the ANS and present the results on a desktop Mac. Using the Program-to-Program Communication Toolbox (“PPCToolbox”), and because AIX’s throughput far exceeded anything the classic Mac OS ever could ever handle, an ANS could augment a whole bunch of Macs at once that didn’t have to stop to do the work themselves. Well, today we’re going to write one of those “symbiotic” applications doing something this little Mystic Color Classic could never efficiently do itself — accessing and processing a JSON API over TLS 1.3 — and demonstrate not only how such an client application looked on the Mac side, but also how the server component worked on the AIX side. If you’re lucky enough to have an ANS running AIX too, you can even compile and run it yourself. But before we do that, it might be a little instructive to talk about how the Apple Network Server came to run AIX in the first place. I had no idea the ANS could do this. That’s an incredibly cool feature, and clearly fits in the whole “the network is the computer” idea that dominated the late ’90s.
Apple has been under pressure in the European Union as the Digital Markets Act antitrust legislation requires the company to allow users to sideload apps outside the App Store to increase competition. 9to5Mac has now found evidence in the iOS 17.2 beta code that the company is indeed moving towards enabling sideloading on iOS devices. The meat of the story here is not that Apple is going to allow sideloading – they were always going to if they want to keep operating in the EU/EEA – but that apparently, they intend to region-lock it to countries in the European Union and European Economic Area. This would mean that consumers in the US would, once again, not be able to benefit from consumer protection laws enacted in the EU.
Eight gigabytes has been the standard RAM load out on new MacBook Pros for the better part of a decade, and in 2023, Apple execs still believe it’s enough for customers. With the launch of Apple’s M3 MacBook Pros last month, a base 14-inch $1,599 model with an M3 chip still only gets you 8GB of unified DRAM that’s shared between the CPU, GPU, and neural network accelerator. In a show of Apple’s typical modesty this week, the tech giant’s veep of worldwide product marketing Bob Borchers has argued, in an interview with machine-learning engineer Lin YilYi, that the Arm-compatible, Apple-designed M-series silicon and software stack is so memory efficient that 8GB on a Mac may equal 16GB on a PC – so we therefore ought to be happy with it. Eight gigabyte of RAM in and of itself isn’t an issue, on a budget machine. Apple is selling incredibly expensive machines labelled as “pro” with a mere 8 GB, and charges EUR200 for another 8, which is highway robbery, plain and simple. I wonder how many people at Apple – at any level – use Macs with 8 GB of RAM. I have a feeling that number is quite low.
Bruce Lawson writes: This week, I’ve had the pleasure to read the post-modernist triumph that is CASES DMA.100013 Apple – online intermediation services – app stores, DMA.100025 Apple – operating systems and DMA.100027 Apple – web browsers (PDF), which details some of Apple’s attempts to avoid being regulated. I call it a “post-modernist triumph” because its prose is almost as incomprehensible as James Joyce’s Finnegans Wake, and it is so full of preposterous lies and contradictions that it can only be sanely read as a metatextual joke like the Illuminatus! Trilogy. In order to avoid having Safari being deemed a Core Platform Service (and thus falling under the remit of DMA), Apple argues “Look, those Safaris on iOS, iPadOS, MacOS, TvOS, WatchOS are TOTALLY DIFFERENT PRODUCTS and none of them have enough users in the EU for you to even think about regulating us, alright? We’re a tiny start-up! Will nobody think of the children?!?”. (I paraphrase somewhat). Entirely unsurprisingly, Apple’s legal contortions did not work – the EU basically tossed this nonsense out right away, using Apple’s own marketing claims about Safari against them.
I was yet again spectacularly wrong in speculating that we had another eight months to wait before Apple would release the first Macs with M3 chips. Another few days and the first will be upon us, and the fortunate few will start bragging or moaning about their performance. That has suddenly grown more complex: the number of each CPU core type has diversified with the M3 Pro in particular. This article looks at some of the factors involved in comparing CPU performance across Apple’s expanded range of M-series chips. As Apple’s line-up of processors grows, it’s becoming harder to keep track of all the details. This article does a good job of highlighting some of the changes coming inside M3-based Macs.
Apple is releasing a slew of updates for its latest operating systems today, including iOS and iPadOS 17.1, macOS Sonoma 14.1, watchOS 10.1, and others. The company is also releasing security updates for a few previous-generation operating systems, so that people who aren’t ready to upgrade (and older devices that can’t upgrade) will still be protected from new exploits. If you have a bunch of Apple devices, it’s going to be a busy day. You might also want to take a look at your Apple subscriptions, because the company massively increased its prices across the board without advance notice.
A director from the White House announced that Apple plans to significantly expand access to device repairs for independent repair shops and consumers across the United States. The move is part of the Biden administration’s push for “right to repair” reforms. According to a statement by National Economic Council Director Lael Brainard (via Reuters), Apple will make parts, tools, and documentation needed for repairs available to independent repair shops and consumers nationwide. This will allow third-party technicians and do-it-yourselfers to fix Apple products at fair and reasonable prices quickly. There’s going to be a gotcha. With Apple, there always is.
The Verge reports: The New York Times reports that along with concerns about some of the guests booked to be on The Problem With Jon Stewart, Stewart’s intended discussions of artificial intelligence and China were a major concern for Apple. Though new episodes of the show were scheduled to begin shooting in just a few weeks, staffers learned today that production had been halted. According to The Hollywood Reporter, ahead of its decision to end The Problem, Apple approached Stewart directly and expressed its need for the host and his team to be “aligned” with the company’s views on topics discussed. Rather than falling in line when Apple threatened to cancel the show, Stewart reportedly decided to walk. Props to Stewart for telling Apple to shove it, but this once again highlights that Apple and Tim Cook are nothing but propaganda mouthpieces for the Chinese Communist Party.
But thanks to all those other cyberdogs, Apple’s own Cyberdog — a seemingly ordinary web browser and Internet suite with some unusual capabilities — has since slid into search engine obscurity. Apple had some big plans for it, though, and even wanted to give developers a way to develop their own components they could run inside of it. Not just plugins, either: we’re talking viewers, UI elements and even entire protocol handlers, implemented using Apple’s version of OpenDoc embedding. The Apple of the ’90s is a treasure trove of weird stuff and random nonsense that never made it anywhere, and I’m always here for it.
