An anonymous reader quotes a report from Ars Technica: For months, a small group of volunteers has worked to get this Arch Linux-based distribution up and running on Apple Silicon Macs, adapting existing drivers and (in the case of the GPU) painstakingly writing their own. And that work is paying off -- last week, the team released its first alpha installer to the general public, and as of yesterday, the software supports the new M1 Ultra in the Mac Studio. In the current alpha, an impressive list of hardware already works, including Wi-Fi, USB 2.0 over the Thunderbolt ports (USB 3.0 only works on Macs with USB-A ports, but USB 3.0 over Thunderbolt is "coming soon"), and the built-in display. But there are still big features missing, including DisplayPort and Thunderbolt, the webcam, Bluetooth, sleep mode, and GPU acceleration. That said, regarding GPU acceleration, the developers say that the M1 is fast enough that a software-rendered Linux desktop feels faster on the M1 than a GPU-accelerated desktop feels on many other ARM chips.

Asahi's developers don't think the software will be "done," with all basic M1-series hardware and functionality supported and working out of the box, "for another year, maybe two." By then, Apple will probably have introduced another generation or two of M-series chips. But the developers are optimistic that much of the work they're doing now will continue to work on future generations of Apple hardware with relatively minimal effort. [...] If you want to try Asahi Linux on an M1 Mac, the current installer is run from the command line and requires "at least 53GB of free space" for an install with a KDE Plasma desktop. Asahi only needs about 15GB, but the installer requires you to leave at least 38GB of free space to the macOS install so that macOS system updates don't break. From there, dual-booting should work similarly to the process on Intel Macs, with the alternate OS visible from within Startup Disk or the boot picker you can launch when your start your Mac. Future updates should be installable from within your new Asahi Linux installation and shouldn't require you to reinstall from scratch.

Despite being easily removable since it is not soldered down, the Mac Studio's SSD storage is not currently user-upgradeable due to a software block, YouTuber Luke Miani has discovered. MacRumors reports: Initial teardowns suggested that the Mac Studio's storage could be upgradeable since it is not soldered in place. Each Mac Studio contains two internal SSD slots, and the SSDs themselves can be freely swapped between the connectors. In a video on his YouTube channel, Miani tested if the Mac Studio's storage is user upgradeable in practice. Miani wiped the SSD of a Mac Studio, removed it from the machine, and inserted it into an empty SSD slot in another Mac Studio, but the Mac's status light blinked SOS and would not boot.

The Mac Studio recognizes the SSD, but Apple's software prevents it from booting, suggesting that this is a conscious decision by Apple to prevent users from upgrading their storage themselves. On its website, Apple claims that the Mac Studio's SSD storage is "not user accessible" and encourages users to configure the device with enough storage at the point of purchase. It now seems that the purpose of the easily replaceable storage is to aid repairs performed by authorized technicians, who likely will have software tools that enable the Mac Studio to boot from different internal storage. Since the prevention of user-upgradeability appears to simply be due to a software block, Apple could enable users to upgrade their own storage in the future via an update.

Tom's Guide tested a Mac Studio workstation equipped with an M1 Ultra with the Geekbench 5.4 CPU benchmarks "to get a sense of how effectively it handles single-core and multi-core workflows."

"Since our M1 Ultra is the best you can buy (at a rough price of $6,199) it sports a 20-core CPU and a 64-core GPU, as well as 128GB of unified memory (RAM) and a 2TB SSD."

Slashdot reader exomondo shares their results: We ran the M1 Ultra through the Geekbench 5.4 CPU benchmarking test multiple times and after averaging the results, we found that the M1 Ultra does indeed outperform top-of-the-line Windows gaming PCs when it comes to multi-core CPU performance. Specifically, the M1 Ultra outperformed a recent Alienware Aurora R13 desktop we tested (w/ Intel Core i7-12700KF, GeForce RTX 3080, 32GB RAM), an Origin Millennium (2022) we just reviewed (Core i9-12900K CPU, RTX 3080 Ti GPU, 32GB RAM), and an even more 3090-equipped HP Omen 45L we tested recently (Core i9-12900K, GeForce RTX 3090, 64GB RAM) in the Geekbench 5.4 multi-core CPU benchmark.

However, as you can see from the chart of results below, the M1 Ultra couldn't match its Intel-powered competition in terms of CPU single-core performance. The Ultra-powered Studio also proved slower to transcode video than the afore-mentioned gaming PCs, taking nearly 4 minutes to transcode a 4K video down to 1080p using Handbrake. All of the gaming PCs I just mentioned completed the same task faster, over 30 seconds faster in the case of the Origin Millennium. Before we even get into the GPU performance tests it's clear that while the M1 Ultra excels at multi-core workflows, it doesn't trounce the competition across the board. When we ran our Mac Studio review unit through the Geekbench 5.4 OpenCL test (which benchmarks GPU performance by simulating common tasks like image processing), the Ultra earned an average score of 83,868. That's quite good, but again it fails to outperform Nvidia GPUs in similarly-priced systems.
They also share some results from the OpenCL Benchmarks browser, which publicly displays scores from different GPUs that users have uploaded: Apple's various M1 chips are on the list as well, and while the M1 Ultra leads that pack it's still quite a ways down the list, with an average score of 83,940. Incidentally, that means it ranks below much older GPUs like Nvidia's GeForce RTX 2070 (85,639) and AMD's Radeon VII (86,509). So here again we see that while the Ultra is fast, it can't match the graphical performance of GPUs that are 2-3 years old at this point — at least, not in these synthetic benchmarks. These tests don't always accurately reflect real-world CPU and GPU performance, which can be dramatically influenced by what programs you're running and how they're optimized to make use of your PC's components.
Their conclusion? When it comes to tasks like photo editing or video and music production, the M1 Ultra w/ 128GB of RAM blazes through workloads, and it does so while remaining whisper-quiet. It also makes the Mac Studio a decent gaming machine, as I was able to play less demanding games like Crusader Kings III, Pathfinder: Wrath of the Righteous and Total War: Warhammer II at reasonable (30+ fps) framerates. But that's just not on par with the performance we expect from high-end GPUs like the Nvidia GeForce RTX 3090....

Of course, if you don't care about games and are in the market for a new Mac with more power than just about anything Apple's ever made, you want the Studio with M1 Ultra.

"Asahi Linux aims to bring you a polished Linux experience on Apple Silicon Macs," explains the project's web site.

And now that first Asahi Linux alpha release is out — ready for testing on M1, M1 Pro, and M1 Max machines (except Mac Studio): We're really excited to finally take this step and start bringing Linux on Apple Silicon to everyone. This is only the beginning, and things will move even more quickly going forward!

Keep in mind that this is still a very early, alpha release. It is intended for developers and power users; if you decide to install it, we hope you will be able to help us out by filing detailed bug reports and helping debug issues. That said, we welcome everyone to give it a try — just expect things to be a bit rough.... Asahi Linux is developed by a group of volunteers, and led by marcan as his primary job. You can support him directly via Patreon and GitHub Sponsors....

Can I dual-boot macOS and Linux?

Yes! In fact, we expect you to do that, and the installer doesn't support replacing macOS at this point. This is because we have no mechanism for updating system firmware from Linux yet, and until we do it makes sense to keep a macOS install lying around for that. You can have as many macOS and Linux installs as you want, and they will all play nicely and show up in Apple's boot picker. Each Linux install acts as a self-contained OS and should not interfere with the others.

Note that keeping a macOS install around does mean you lose ~70GB of disk space (in order to allow for updates, since the macOS updater is quite inefficient). In the future we expect to have a mechanism for firmware updates from Linux and better integration, at which point we'll be comfortable recommending Linux-only setups....

Is this just Arch Linux ARM?

Pretty much! Most of our work is in the kernel and a few core support packages, and we rely on Linux's excellent existing ARM64 support. The Asahi Linux reference distro images are based off of Arch Linux ARM and simply add our own package repository, which only adds a few packages. You can freely convert between Arch Linux ARM and Asahi Linux by adding or removing this repository and the relevant packages, although vanilla Arch Linux ARM kernels will not boot on these machines at this time.
The project's home page adds that "All contributors are welcome, of any skill level!"

"Doing this requires a tremendous amount of work, as Apple Silicon is an entirely undocumented platform," the team explains. "In particular, we will be reverse engineering the Apple GPU architecture and developing an open-source driver for it." But they're already documenting the Apple Silicon platform on their GitHub wiki. We will eventually release a remix of Arch Linux ARM, packaged for installation by end-users, as a distribution of the same name. The majority of the work resides in hardware support, drivers, and tools, and it will be upstreamed to the relevant projects....

Apple allows booting unsigned/custom kernels on Apple Silicon Macs without a jailbreak! This isn't a hack or an omission, but an actual feature that Apple built into these devices. That means that, unlike iOS devices, Apple does not intend to lock down what OS you can use on Macs (though they probably won't help with the development). As long as no code is taken from macOS to build the Linux support, the result is completely legal to distribute and for end-users to use, as it would not be a derivative work of macOS.
An interesting observataion from Slashdot reader mrwireless: It once again seems Apple is informally supportive of these efforts, as the recent release of OS Monterey 12.3 makes the process even simpler. As Twitter user Matthew Garrett writes:

"People who hate UEFI should read https://github.com/AsahiLinux/... — Apple made deliberate design choices that allow third party OSes to run on M1 hardware without compromising security, and with much less closed code than on basically any modern x86."

An anonymous reader shares a report:When Apple introduced the M1 Ultra -- the company's most powerful in-house processor yet and the crown jewel of its brand new Mac Studio -- it did so with charts boasting that the Ultra capable of beating out Intel's best processor or Nvidia's RTX 3090 GPU all on its own. The charts, in Apple's recent fashion, were maddeningly labeled with "relative performance" on the Y-axis, and Apple doesn't tell us what specific tests it runs to arrive at whatever numbers it uses to then calculate "relative performance." But now that we have a Mac Studio, we can say that in most tests, the M1 Ultra isn't actually faster than an RTX 3090, as much as Apple would like to say it is.

Apple has rolled out macOS 12.3 and iPadOS 15.4, bringing the highly-anticipated (and delayed) Universal Control feature. Engadget reports: The tool, which is in beta, allows you to control a Mac and iPad at the same time with a single keyboard and mouse (or trackpad). You can enter text on either device and drag files between them. Apple initially said Universal Control would be available last fall, but in December it delayed the release until this spring. Apple has enhanced spatial audio on M1-powered systems as well. Apple Music now has dynamic head tracking support for compatible AirPods. You'll find settings for fixed and head-tracking spatial audio in the Control Center. There's also several new emoji, more filters for the Podcasts app, optional notes for saved passwords and more accurate battery capacity readings, among other changes.

iOS 15.4 was also released today, adding the option to use Face ID while wearing a mask. "The updates also add 37 new emoji characters and they lay the groundwork for the new 'Tap to Pay on iPhone' feature that allows NFC-compatible iPhones to accept payments through Apple Pay," reports MacRumors. "There are also updates to add custom domains to iCloud Mail right on device, Siri enhancements, new Emergency SOS features, and tons more."

Does Apple have a "Pro" problem? "[Y]ears of Apple and competitors slapping the name onto wireless earbuds and slightly fancier phones have made it hard to tell what 'Pro' even means," argues The Verge's Mitchell Clark. It could be the reason behind Apple's recently-launched Mac "Studio." From the report: From the jump, Apple made it clear who the Mac Studio and Studio Display were for. It showed them being used by musicians, 3D artists, and developers in its presentation, and the message was clear: these are products for creative professionals or people who aspire to be creative professionals. You know, the same exact crowd it's targeted with MacBook Pro commercials for years. "My first thought was, 'Oh, I wonder when the iPhone Studio comes out,'" says Jonathan Balck, co-founder and managing director of ad agency Colossus, in an interview with The Verge. "Pro was exclusive, and it was about one way of doing things, but the whole culture is moving toward creativity," he adds while musing whether we could see Apple's Pro branding shift to become Studio branding instead.

[T]o me, the Mac Studio line is a clear successor to Apple's iMac Pro. Both computers are powered by monstrous CPUs and come standard with 10Gb Ethernet and a healthy crop of Thunderbolt and USB ports. I'm convinced that, had Apple released the new Studio even two years ago, it would've put "Pro" in the name. (Though, to play devil's advocate, I'm not as sure it would've done so for the Studio Display.) Some marketing experts tell me that the word "Pro" is starting to get long in the tooth, and not just from overuse. "The previous term Pro is, in my opinion, outdated and dry," says Keith Dorsey, founder and CEO of the creative marketing group and management company YoungGuns Entertainment. Balck agrees; "If you look at the word Pro, that is in many ways restrictive," he says in an interview, explaining that when you say a product is "professional," it evokes ideas like job interviews, portfolios, and standoffishness. Pro products, he says, come across as just for those who use creativity to get a paycheck.

The reason Apple may need to, though, is because it led the industry in thoroughly overusing the word "Pro" to the point where it's lost all meaning. It's hard to pinpoint where exactly this started (though, in my mind, it was with the two-port MacBook Pro model), but now the word gets slapped on everything. Want to sell wireless earbuds for even more money? Those are Pro earbuds now. Want to have a regular and fancy version of your phone? No problem, call the nice one the Pro. [...] But Apple's new word, "studio," seems to come ready-made to excite the company's target audience.

Apple has confirmed that the brand new Studio Display will work when connected to PCs, but critical new features of the display will not carry over and the experience will be lacking compared to using the display with a Mac. MacRumors adds: Features that require macOS, such as True Tone, will not work when connected to PCs. When connected to a PC, the webcam in the Studio Display will work as a normal webcam, but Center Stage does require macOS.

At its "Peek Performance" event, Apple today announced the third-generation iPhone SE, featuring the A15 Bionic chip, improved battery life, 5G connectivity, a new camera system, and more, all for a starting price of $429. MacRumors reports: The new iPhone SE features the same 4.7-inch display as the current model, but now offers the toughest glass in a smartphone on the front and back -- the same as on the back of the iPhone 13 and iPhone 13 Pro. The device's new 12MP Wide camera system offers a range of improvements and computational photography features including Deep Fusion, Photographic Styles, Portrait Mode, and Smart HDR 4.

The new iPhone SE contains the same A15 Bionic chip from the iPhone 13 and iPhone 13 Pro. [...] The A15 Bionic also gives the new iPhone SE longer battery life than the previous-generation and older 4.7-inch iPhone models despite having a compact form-factor and 5G connectivity. It continues to support fast charging and be compatible with Qi-certified chargers for wireless charging. Along with the new iPhone SE, Apple also unveiled the all-new Mac Studio and Studio Display, flagship M1 Ultra desktop processor, and updated iPad Air.

Apple has finally discontinued the 27-inch iMac. Minutes after Apple's Peek Performance event wrapped, the last of the Intel iMacs disappeared from its online store.

Apple has announced the Mac Studio, a desktop system that looks like the Mac Mini on the outside but packs a lot more power on the inside. The Mac Studio features both Apple's M1 Max chip as well as a new, even more powerful processor, the M1 Ultra. It looks a bit similar to the Mac Mini, but Apple claims that the new device will be faster than even its top-of-the-line Mac Pro. From a report: The chassis is 7.7 inches by 3.7 inches; Apple claims it "fits perfectly under most displays" and will remain quiet under heavy workloads. The rear includes four Thunderbolt 4 ports as well as a 10Gb Ethernet port, two USB-A ports, an HDMI, and an audio jack. It supports Wi-Fi 6 and Bluetooth 5.0. The front includes two USB-C ports (10 Gbps on M1 Max systems, 40 Gbps/Thunderbolt 4 on M1 Ultra systems) and an SD card slot. The Mac Studio can support up to four Pro Display XDRs and a 4K TV, Apple says. Apple claims that the Mac Studio with M1 Max will deliver 50 percent faster CPU performance than a Mac Pro with a 16-core Xeon and 2.5 times faster CPU performance than a 27-inch iMac with a 10-core Core i9. The M1 Ultra configuration purportedly has 3.8 times faster CPU performance than that 27-inch iMac and is up to 90 percent faster than the 16-core Mac Pro. The Mac Studio with M1 Max will start at $1,999, and M1 Ultra models will start at $3,999. The studio display is $1,599.

In a 15-minute-long video, YouTuber Quinn Nelson from Snazzy Labs explains how he managed to shrink the current M1 Mac Mini by 78% without harming performance. 9to5Mac reports: In conclusion, by rearranging the internals and swapping out the power supply, Nelson was able to reduce the size of the Mac mini enclosure by 78%. He organized all the parts inside a 3D-printed body with a mini Mac Pro motif.

The reason that theoretical space savings are so huge is because when Apple released the first round of Apple Silicon computers, they did not change the hardware industrial design at all. So the current Mac Mini enclosure is designed to fit an Intel CPU and circuit board, including having to accommodate the large fans and heat sinks the Intel chip required.

But with the power efficiency of the M1, Apple has the headroom to do something much more drastic. Indeed, a lot of the M1 Mac mini internals is just empty space. The Snazzy Labs video gives a glimpse at what is possible if Apple is more ambitious with the next-generation Mac mini design, and tries to create something truly mini. The CAD files and schematics can be viewed here.

A year and a half later, Amazon's Luna cloud gaming service has formally launched in the U.S. for Android, iOS, Chrome OS, macOS and Windows. Engadget reports: The core Luna+ service with over 100 games will normally cost $10 per month, with the kid-friendly Family Channel and Ubisoft+ Channels available for a respective $6 and $18 per month. Amazon hopes to reel in newcomers by dropping the monthly fees of Luna+ and the Family channel to $6 and $3 for anyone who signs up during March. Existing users just have to maintain their subscriptions to lock in that pricing.

The official debut comes alongside some new channels. A Prime Gaming channel, as the name implies, gives Amazon Prime members a free, rotating mix of games. The March selection will include titles like Devil May Cry 5 and Flashback. Pay $5 per month for the Retro Channel and you'll get Capcom and SNK classics like Street Fighter II Hyper Fighting and Metal Slug 3, while a similar outlay for the Jackbox Games Channel provides access to all eight Jackbox Party Pack titles. Luna's latest update also makes it simpler to stream gameplay from a Fire TV device, Mac or Windows PC on Twitch.

Apple appears to be exploring the possibility of integrating a fully functioning Mac within a keyboard, reminiscent of home computers of the 80s, such as the Commodore 64 and Sinclair ZX Spectrum. MacRumors: The concept was revealed by the U.S. Patent and Trademark Office in a new Apple patent application called "Computer in an input device," which describes a thicker Magic Keyboard-style chassis with "all the components of a high performance computer" integrated under the hood. The patent describes the premise for such a device, which could be plugged into a separate external display via a single I/O port designed to receive both data and power, and wirelessly paired with a trackpad or mouse for additional input.

Google has announced a new version of Chrome OS called Chrome OS Flex, which is designed to run on old PCs and Macs. The Verge reports: The operating system can be installed "within minutes," according to Google's blog post. Google told me that Chrome OS Flex will look and feel identical to Chrome OS on a Chromebook -- it's built from the same code base and follows the same "release cadence." It did caveat that some features may be dependent on the hardware of the PC you're using. In fact, it said this for every specific feature I asked about, including always-on Google Assistant and Android phone syncing. So, if you're going to try this, keep an eye out.

If you want to try out Chrome OS Flex yourself, you can learn more on the Chrome Enterprise website. Note that the OS is still in early access mode, so you may encounter bugs -- you can boot it directly from a USB drive if you'd rather poke around before installing it on your machine.

An anonymous reader shares a report: In 2014, Google made a remarkable offer: anyone with a Google Apps for Education account in the US got unlimited storage for free. The logic was sound at the time. Three years earlier, the tech giant had launched the Chromebook -- cheap, robust and secure, the web-browser-based kit was a natural fit for education. The cloud was its primary storage, so what could be better than making that bigger than any hard disk in a Mac or Windows PC could ever swallow? The idea was that if you catch users when they are young, they're yours for life. The axiom had already been tested by both Apple and Microsoft, with creative types and workers in jobs with sensible shoes respectively. Google played on its own strengths as the first cloud-native platform for everyone. And lo, it was good. Seven years later, Google has killed the deal.

In place of all you can stash, each institution in the scheme was getting a total pool of 100TB to give to student and teacher alike. If they wanted anything more, the cash register was open. For a small primary school with a couple of hundred pupils, this was perfectly adequate. A large science-heavy university could have a single experiment using that much, however. That announcement was a year ago, and gave existing users 18 months of grace, with new users denied the unlimited package from, well, now. Those with experience of academic deadlines won't be surprised that it has taken this long for lots of people to notice.

Liliputing reports: When Valve's Steam Deck begins shipping to customers later this month, the handheld gaming PC will be running a Linux-based operating system called Steam OS. And that could give gaming on Linux a bit of a boost.

While Valve's game client has been able to run on Linux for years, as of last month just over 1% of Steam users were running Linux (and fewer than 3% were using macOS, with Windows holding a 96% share). It'll be interesting to see if that starts to change once the Steam Deck hits the streets. And if it does, maybe we'll see more game makers add support for Linux... but one of the most popular games around isn't going to add Linux support anytime soon: Epic CEO Tim Sweeney says the company has no plans to port Fortnite to Linux.

He says it's because Epic doesn't "have confidence that we'd be able to combat cheating at scale under a wide array of kernel configurations including custom ones," but it's an interesting take since Epic has already ported its anti-cheat software to support Mac and Linux devices including the Steam Deck.

Popular video conferencing platform Zoom this week released an important update to its macOS app following user reports about the microphone not being disabled after ending a conference. Luckily, according to the company, this was just a bug that has now been fixed. 9to5Mac reports: Since December last year, a number of users have been complaining about this bug in the Zoom Community (via The Register). According to them, the Mac's microphone stayed active even after ending a Zoom conference -- which certainly raised privacy concerns.

Zoom has confirmed that there was a bug in its macOS app that could cause the orange microphone-in-use indicator to appear even after leaving a call. According to a company representative, the latest version of the app no longer has this problem: "We experienced a bug relating to the Zoom client for macOS, which could show the orange indicator light continue to appear after having left a meeting, call, or webinar. This bug was addressed in the Zoom client for macOS version 5.9.3 and we recommend you update to version 5.9.3 to apply the fix."

According to tech reporter and Apple leaker Mark Gurman, Apple is preparing to launch four M2 Macs throughout 2022. MacWorld reports: The first models will likely arrive later in the year, with the redesigned MacBook Air leading the way, followed by a new 13-inch MacBook Pro, 24-inch iMac, and entry-level Mac mini. A DigiTimes report on Tuesday said the 13-inch MacBook Pro may launch at Apple's spring event to usher in the new chip. Like 2021, Apple will be releasing Macs with several different chips in 2022. The M2 will be a successor to the M1, likely with the same 8-core design (four performance cores and four efficiency cores), and the M1 Pro and M1 Max will make their way into more high-end Macs. The first of those, the 27-inch iMac, could arrive at Apple's spring event, with a Mac mini coming later in the year. [...] There's also a new Mac Pro due in 2022 as the culmination of the Apple silicon transition. That would mean every Mac line is due for a refresh this year and nearly every model, with only the recently released 14-inch and 16-inch MacBook Pro escaping without a refresh.

According to CNBC, Apple "beat analyst estimates for sales in every product category except iPads and overall revenue was up 11% annually." This is despite global supply chain challenges caused by the covid-19 pandemic. Here is how Apple did in the quarter ending Dec. 25 versus Refinitiv consensus estimates (via CNBC): EPS: $2.10 vs. $1.89 estimated, up 25% year-over-year
Revenue: $123.9 billion vs. $118.66 billion estimated, up 11% year-over-year
iPhone revenue: $71.63 billion vs. $68.34 billion estimated, up 9% year-over-year
Services revenue: $19.52 billion vs. $18.61 billion estimated, up 24% year-over-year
Other Products revenue: $14.70 billion vs. $14.59 billion estimated, up 13% year-over-year
Mac revenue: $10.85 billion vs. $9.52 billion estimated, up 25% year-over-year
iPad revenue: $7.25 billion vs. $8.18 billion estimated, down 14% year-over-year
Gross margin: 43.8% vs. 41.7% estimated

[Apple CEO Tim Cook] said that the company's supply issues were improving. He said that in terms of supply challenges, the December quarter was worse than Apple's September quarter, but that he is projecting the March quarter to improve. "Our biggest issue is chip supply, it's chip supply on legacy nodes," Cook said. "And we're doing okay on the leading edge stuff." [...] "What we expect for the March quarter is solid year-over-year revenue growth," Cook said. "And we expect supply constraints in the March quarter to be less than they were in the December quarter."
