The first macOS Tahoe beta appears to drop support for legacy FireWire 400 and 800, making it impossible to sync or mount older iPods and external drives that rely on the standard. MacRumors reports: Unlike on macOS Sequoia and earlier versions, the first macOS Tahoe beta does not include a FireWire section in the System Settings app. Of course, this could all end up being a false alarm. It is still early in the macOS Tahoe beta testing cycle, and FireWire support could return in a later beta version, or in time for the final release.

FireWire was primarily developed by Apple, but it was later standardized as IEEE 1394 and licensed for use in non-Apple devices. iPods started to transition from FireWire to USB for data transfer in 2003, so the standard is very outdated, but it would still be the end of an era if macOS Tahoe drops it. The last Mac with a FireWire port was released in 2012, so connecting older iPods and FireWire drives to newer Macs has long required the use of adapters.

Apple software chief Craig Federighi has ruled out bringing macOS to the iPad, amusingly using a kitchen utensil analogy to explain the company's design philosophy. "We don't want to create a boat car or, you know, a spork," Federighi said in an interview. "Someone said, 'If a spoon's great, a fork's great, then let's combine them into a single utensil, right?' It turns out it's not a good spoon and it's not a good fork. It's a bad idea. And so we don't want to build sporks."

The new version of iPadOS, which will ship to consumers later this year, features dynamically resizable windows that users can drag by their corners and a menu bar that is accessible through swipe gestures or cursor movement.

Some observers might consider the iPad Pro itself a "convertible" product that blurs the line between tablet and laptop, he said. However, the Mac and iPad serve distinct purposes, he asserted. "The Mac lets the iPad be iPad," he said adding that Apple's objective "has not been to have iPad completely displace those places where the Mac is the right tool for the job." Rather than full convergence, Federighi said the iPad "can be inspired by elements of the Mac" while remaining a separate platform. "I think the Mac can be inspired by elements of iPad, and I think that that's happened a great deal."

Apple's macOS 26 "Tahoe" introduces a new disk image format called ASIF, designed to dramatically improve performance over previous formats like UDRW and sparse bundles -- achieving near-native read/write speeds for virtual machines and general disk image use. The Eclectic Light Company reports: Apple provides few technical details, other than stating that the intrinsic structure of ASIF disk images doesn't depend on the host file system's capabilities, and their size on the host depends on the size of the data stored in the disk. In other words, they're a sparse file in APFS, and are flagged as such. [...]

Conclusions:
- Where possible, in macOS 26 Tahoe in particular, VMs should use ASIF disk images rather than RAW/UDRW.
- Unless a sparse bundle is required (for example when it's hosted on a different file system such as that in a NAS), ASIF should be first choice for general purpose disk images in Tahoe.
- It would be preferable for virtualizers to be able to call a proper API rather than a command tool.
- Keep an eye on C-Command's DropDMG. I'm sure it will support ASIF disk images soon.

BrianFagioli shares a report from NERDS.xyz: Apple has released a new developer tool on GitHub called Container, offering a fresh approach to running Linux containers directly on macOS. Unlike Docker or Podman, this tool is designed to feel at home in the Apple ecosystem and hooks into frameworks already built into the operating system. Container runs standard OCI images, but it doesn't use a single shared Linux VM. Instead, it creates a small Linux virtual machine for every container you spin up. That sounds heavy at first, but the VMs are lightweight and boot quickly. Each one is isolated, which Apple claims improves both security and privacy. Developers can run containerized workloads locally with native macOS support and without needing to install third-party container platforms.

Long-time Slashdot reader jaromil writes: As a fun project, we hacked together a C interpreter (based on Tiny C Compiler) that compiles C code in-memory and runs it live.

CJIT today is a 2MB executable that can do a lot, including call functions from any installed library on Linux, Windows, and MacOSX.
Slashdot reader oliwer points out "they are also including a REPL, which could be interesting." And the CJIT web page promises there's "no EULA to sign, no IDE to install... 100% Free and open source!"

It also says the project was inspired by Terry Davis (TempleOS) and Fabrice Bellard (Tiny C Compiler).

The latest Steam client drops support for operating systems older than Windows 10 or macOS 10.15 Catalina. "That means Mac users can't run 32-bit games anymore, as all macOS versions from Catalina onward only run 64-bit binaries," reports The Register. From the report: [I]f you have a well-specified older Mac, here is another reason to check out Open Core Legacy Patcher. For now, macOS 10.15 Catalina will do but we suspect it won't for long. This version of Steam uses the equivalent to Chrome 126: "Updated embedded Chromium build in Steam to 126.0.6478.183." However, versions since Chrome 128 require macOS 11 or newer. For now, Catalina will work -- but the next significant Steam update will update Chromium as well, and there's a high probability that that will drop support for 10.15.

So, if you're using OCLP to install a newer macOS, you should probably go directly to Big Sur. In The Reg FOSS desk's testing, we found that Big Sur ran reasonably well on a machine with Intel HD 520 graphics, although the same hardware ran very poorly with macOS 12 Monterey. Unfortunately, the inevitable end is in sight for older Macs. That said, the November 2024 Steam client update brings several "wins," including a built-in Game Recording feature, an upgraded Chromium browser engine, and the new "Scout" Linux runtime environment for improved compatibility and performance, especially on the Steam Deck and Linux distros. Additionally, it delivers bug fixes and enhancements for modern OS users.

An update to OpenAI's ChatGPT app for macOS adds integration with third-party apps, including developer tools such as VS Code, Terminal, iTerm2 and Apple's Xcode. 9to5Mac reports: In a demo seen by 9to5Mac, ChatGPT was able to understand code from an Xcode project and then provide code suggestions without the user having to manually copy and paste content into the ChatGPT app. It can even read content from more than one app at the same time, which is very useful for working with developer tools. According to OpenAI, the idea is to expand integration to more apps in the future. For now, integration with third-party apps is coming exclusively to the Mac version of ChatGPT, but there's another catch. The feature requires a paid ChatGPT subscription, at least for now.

ChatGPT Plus and Team subscribers will receive access to integration with third-party apps on macOS starting today, while access for Enterprise and Education users will be rolled out "in the next few weeks." OpenAI told 9to5Mac that it wants to make the feature available to everyone in the future, although there's no estimate of when this will happen. For privacy reasons, users can control at any time when and which apps ChatGPT can read. The app can be downloaded here.

Apple's latest macOS 15 "Sequoia" update, released earlier this week, has disrupted security tools from major providers including CrowdStrike, SentinelOne, and Microsoft, according to reports. The extent and cause of the disruption remain unclear.

Ryan Christoffel writes via 9to5Mac: Since the Mac doesn't have the same locked-down app distribution system of iOS and iPadOS, Apple has created other tools meant to protect users. Some of those tools include app signing and notarization. Essentially, these provide a way for Apple to perform a level of vetting for macOS apps, even ones that don't hit the Mac App Store. The intent is to ultimately prevent harmful software from being inadvertently opened by Mac users. Trying to open an app that isn't correctly signed or notarized results in some scary warnings. But until now, power users could bypass those warnings -- and Apple's overall security process -- using a Control-click shortcut. But that shortcut is going away in macOS Sequoia.

According to a new post on the Apple Developer site: "In macOS Sequoia, users will no longer be able to Control-click to override Gatekeeper when opening software that isn't signed correctly or notarized. They'll need to visit System Settings > Privacy & Security to review security information for software before allowing it to run." The post then urges developers to make sure their software is properly signed so users won't need to jump through these hoops.

At its Worldwide Developers Conference, Apple formally introduced macOS 15, codenamed "Sequoia." The new release combines features from iOS 18 with Mac-specific improvements. One notable addition is automated window tiling, allowing users to arrange windows on their screen without manual resizing or switching to full-screen mode. Another feature, iPhone Mirroring, streams the iPhone's screen to the Mac, enabling app use with the Mac's keyboard and trackpad while keeping the phone locked for privacy.

Gamers will appreciate the second version of Apple's Game Porting Toolkit, simplifying the process of bringing Windows games to macOS and vice versa. Sequoia also incorporates changes from iOS and iPadOS, such as RCS support and expanded Tapback reactions in Messages, a redesigned Calculator app, and the Math Notes feature for typed equations in Notes. Additionally, all Apple platforms and Windows will receive a new Passwords app, potentially replacing standalone password managers. A developer beta of macOS Sequoia is available today, with refined public betas coming in July and a full release planned for the fall.

Michael Larabel reports via Phoronix: Building off the recent release of Fedora 40, Fedora Asahi Remix 40 is now available for this downstream of Fedora Linux that's optimized to run on Apple Silicon ARM systems. Fedora Asahi Remix continues to be one of the best ways of enjoying a Linux experience atop recent Apple Macs making use of their in-house M1/M2/M3 SoCs. With the Fedora Asahi Remix 40 release there is now conformant OpenGL 4.6 support thanks to the upgraded Mesa. There is also improved device compatibility with its newer kernel.

Fedora Asahi Remix continues to cater to using the KDE Plasma desktop by default. With the upgrade to Fedora Asahi Remix 40 this also means now transitioning to the KDE Plasma 6.0 desktop environment for their flagship desktop experience. A GNOME variant using GNOME 46 is also available. You can learn more about the release via FedoraMagazine.org. Installation options are available at FedoraProject.org.

The macOS Sonoma 14.4 update introduces a bug affecting iCloud Drive's versioning system, where users with "Optimize Mac Storage" enabled can lose all previous versions of a file removed from local storage. MacRumors reports: Versions are normally created automatically when users save files using apps that work with the version system in macOS. According to The Eclectic Light Company's Howard Oakley, users running macOS 14.4 that have "Optimize Mac Storage" enabled should be aware that they are at risk of losing all previously saved versions of a file if they opt to remove it from iCloud Drive local storage: "In previous versions of macOS, when a file is evicted from local storage in iCloud Drive [using the Remove Download option in the right-click contextual menu], all its saved versions have been preserved. Download that file again from iCloud Drive, and versions saved on that Mac (but not other Macs or devices) have remained fully accessible. Do that in 14.4, and all previous versions are now removed, and lost forever."

Oakley said his own tests confirmed that this behavior does not happen in macOS Sonoma 14.3 or macOS Ventura, so it is exclusive to macOS 14.4. For users who have already updated, he suggests either not saving files to iCloud Drive at all, or turning off Optimize Mac Storage. To perform the latter in System Settings, click your Apple ID, select iCloud, and then toggle off the switch next to "Optimize Mac Storage." You may need to perform this action twice -- reports suggest it can turn back on by itself. For a more exhaustive account of the problem, see Oakley's subsequent post.

Hackers targeting individuals in the cryptocurrency sector are using a sophisticated phishing scheme that begins with a malicious link on Calendly. "The attackers impersonate established cryptocurrency investors and ask to schedule a video conference call," reports Krebs on Security. "But clicking the meeting link provided by the scammers prompts the user to run a script that quietly installs malware on macOS systems." From the report: A search in Google for a string of text from that script turns up a December 2023 blog post from cryptocurrency security firm SlowMist about phishing attacks on Telegram from North Korean state-sponsored hackers. "When the project team clicks the link, they encounter a region access restriction," SlowMist wrote. "At this point, the North Korean hackers coax the team into downloading and running a 'location-modifying' malicious script. Once the project team complies, their computer comes under the control of the hackers, leading to the theft of funds."

SlowMist says the North Korean phishing scams used the "Add Custom Link" feature of the Calendly meeting scheduling system on event pages to insert malicious links and initiate phishing attacks. "Since Calendly integrates well with the daily work routines of most project teams, these malicious links do not easily raise suspicion," the blog post explains. "Consequently, the project teams may inadvertently click on these malicious links, download, and execute malicious code."

SlowMist said the malware downloaded by the malicious link in their case comes from a North Korean hacking group dubbed BlueNoroff, which Kaspersky Labs says is a subgroup of the Lazarus hacking group. "A financially motivated threat actor closely connected with Lazarus that targets banks, casinos, fin-tech companies, POST software and cryptocurrency businesses, and ATMs," Kaspersky wrote of BlueNoroff in Dec. 2023.

An anonymous reader quotes a report from Ars Technica: Valve Software's Steam gaming marketplace and app will drop support for macOS 10.13 (High Sierra) and 10.14 (Mojave), according to a support page post. The change will go into effect on February 15, 2024. What will happen exactly? Valve writes: "After that date, existing Steam Client installations on these operating systems will no longer receive updates of any kind including security updates. Steam Support will be unable to offer users technical support for issues related to the old operating systems, and Steam will be unable to guarantee continued functionality of Steam on the unsupported operating system versions."

"The Steam store will stop considering games that offer only 32-bit macOS binaries to be Mac compatible at the end of 2023," Valve writes. The post also notes that fewer than two percent of current Mac users on Steam are running macOS 10.14 or earlier, so this only affects the small number who are holding on to those older versions that supported 32-bit apps. To be clear, lack of support for macOS 10.14 doesn't necessarily mean Steam won't run at all on machines running that OS. It just means Valve won't guarantee it'll work, and won't lift a finger to help if something breaks in the passage of time. It also means users who continue to use the older software could become vulnerable to security risks, disincentivizing continued use.

Richard Speed reports via The Register: Asahi Linux, a project to port Linux to Apple Silicon Macs, has reported a combination of bugs in Apple's macOS that could leave users with hardware in a difficult-to-recover state. The issues revolve around how recent versions of macOS handle refresh rates, and MacBook Pro models with ProMotion displays (the 14 and 16-inch versions) are affected. According to the Asahi team, the bugs lurk in the upgrade and boot process and, when combined, can create a condition where a machine always boots to a black screen, and a Device Firmware Update (DFU) recovery is needed.

Asahi Linux's techies have looked into the issue, having first suspected it had something to do with either having an Asahi Linux installation on a Mac and then upgrading to macOS Sonoma or installing Asahi Linux after a Sonoma upgrade. However, the issue appears to be unconnected to the project. The team said: "As far as we can tell, ALL users who upgraded to Sonoma the normal way have an out-of-date or even broken System RecoveryOS, and in particular MacBook Pro 14" and 16" owners are vulnerable to ending up with a completely unbootable system." While this might sound alarming, the team was at pains to assure users that data was not at risk and only certain versions of macOS were affected -- Sonoma 14.0+ and Ventura 13.6+.

The first bug is related to macOS Sonoma using the previously installed version as System Recovery, which can cause problems when an older RecoveryOS runs into newer firmware. The second occurs if a display is configured to a refresh rate other than ProMotion. According to the Asahi Linux team, the system will no longer be able to boot into old macOS installs or Asahi Linux. "This includes recovery mode when those systems are set as the default boot OS, and also System Recovery at least until the next subsequent OS upgrade." The team noted: "Even users with just 13.6 installed single-boot are affected by this issue (no Asahi Linux needed).

"We do not understand how Apple managed to release an OS update that, when upgraded to normally, leaves machines unbootable if their display refresh rate is not the default. This seems to have been a major QA oversight by Apple."

An anonymous reader quotes a report from Ars Technica: When Apple decides to end update support for your Mac, you can either try to install another OS or you can trick macOS into installing on your hardware anyway. That's the entire point of the OpenCore Legacy Patcher, a community-driven project that supports old Macs by combining some repurposed Hackintosh projects with older system files extracted from past macOS versions. Yesterday, the OCLP team announced version 1.0.0 of the software, the first to formally support the recently released macOS 14 Sonoma. Although Sonoma officially supports Macs released mostly in 2018 or later, the OCLP project will allow Sonoma to install on Macs that go back to models released in 2007 and 2008, enabling them to keep up with at least some of the new features and security patches baked into the latest release.

At WWDC today, Apple announced macOS Sonoma, the latest version of its Mac operating system that includes new features like desktop widgets, aerial screensavers, a new Game mode, and enhancements to apps like Messages and Safari. MacRumors reports: The first feature that Apple detailed was new interactive widgets, which can now be placed right on your desktop. Widgets blend into your desktop wallpaper to not be obtrusive when you're working, and with Continuity you can use the same widgets from your iPhone on your Mac. macOS Sonoma also introduces enhanced video conferencing features, including Presenter Overlay to allow a user to display themselves in front of the content they are sharing. Reactions let users share how they feel within a video session, and Screen Sharing has been improved with a simplified process.

As is usual with macOS updates, Safari is getting numerous new features within Sonoma. There's an update to Private Browsing that provides greater protection from trackers and from people who might have access to the user's device. Profiles within Safari offer a way to separate browsing between topics, like having one for work and one for personal browsing. There's also a new way to create web apps that work like normal apps and let you get to your favorite website faster.

When you're not actively using macOS Sonoma, the new screen savers feature slow-motion videos of various locations worldwide. They shuffle between landscape, Earth, underwater, or cityscape themes, similar to what you'll see on tvOS. For gamers, there's a new Game Mode in macOS Sonoma that delivers an optimized gaming experience with smoother and more consistent frame rates. It dramatically lowers audio latency with AirPods and reduces input latency with game controllers, and it works with any game on Mac. A beta version of macOS Sonoma is now available via the Apple Developer Program, with a public beta launching next month.

As Ars Technica notes, the macOS Sonoma update will only run on a couple generations of Intel Macs. "[I]f you're using anything made before 2018 or anything without an Apple T2 chip in it, you won't be able to run the new OS."

An anonymous reader quotes a report from Ars Technica: Apple has made a tiny bit of progress in the last year when it comes to getting games running on Macs -- titles like Resident Evil Village and a recent No Man's Sky port don't exactly make the Mac a gaming destination, but they're bigger releases than Mac users are normally accustomed to. For getting the vast majority of PC gaming titles running, though, the most promising solution would be a Steam Deck-esque software layer that translates Microsoft's DirectX 12 API into something compatible with Apple's proprietary Metal API. Preliminary support for that kind of translation will be coming to CodeWeavers' CrossOver software this summer, the company announced in a blog post late last week.

CrossOver is a software package that promises to run Windows apps and games under macOS and Linux without requiring a full virtualized (or emulated) Windows installation. Its developers announced that they were working on DirectX 12 support in late 2021, and now they have a sample screenshot of Diablo II Resurrected running on an Apple M2 chip. This early DirectX12 support will ship with CrossOver version 23 "later this summer." The announcement is simultaneously promising and caveat-filled; getting this single game running required fixing multiple game-specific bugs in upstream software projects. Support will need to be added on a game-by-game basis, at least at first.

"Our team's investigations concluded that there was no single magic key that unlocked DirectX 12 support on macOS," CodeWeavers project manager Meredith Johnson wrote in the blog post. "To get just Diablo II Resurrected running, we had to fix a multitude of bugs involving MoltenVK and SPIRV-Cross. We anticipate that this will be the case for other DirectX 12 games: we will need to add support on a per-title basis, and each game will likely involve multiple bugs." In other words, don't expect Steam Deck-esque levels of compatibility with Windows games just yet. There are also still gameplay bugs even in Diablo II Resurrected, though "the fact that it's running at all is a huge win."

joshuark writes: Yikes, gadzooks, and shiver my timbers! Elastic Labs has found surprisingly that 50% of malware comes from one app: MacKeeper, ironically. Ironic in that MacKeeper claims to "keep your Mac clean and safe with zero effort." MacKeeper also has a tainted reputation for being difficult to completely uninstall and as a malicious antivirus.

A new spin on the biblical phrase, "Am I my brother's keeper..." Well, when the inmate is running the asylum. The findings appear in Elastic Security Labs' recently released 2022 Global Threat Report. As Neowin reports, MacKeeper "can be abused by threat actors because it has extensive permissions and access to processes and files."

With that said, the report found that only 6.2% of malware ends up on macOS devices, compared to 54.4% and 39.4% on Windows and Linux, respectively.

Starting with macOS Ventura, released this week, the built-in Preview app on Mac no longer supports PostScript (.ps) and Encapsulated PostScript (.eps) files, according to a new Apple support document. MacRumors reports: Preview can still be used to open these files on macOS Monterey and earlier. Apple did not provide a reason for the change. Apple recommends using other third-party Mac apps that can view or convert PostScript files. It also remains possible to print .ps and .eps files by dragging them into a Mac's printer queue [...].

Developed by Adobe in the 1980s, the .ps and .eps file formats were once widely used for desktop publishing/printing purposes. PostScript was the basis of rendering on the NeXT operating system, and was mostly replaced by the PDF format in Mac OS X.
