Howard Oakley: This table summarises read and write performance of the most popular types of disk image prior to macOS Tahoe, and demonstrates how sparse bundles have consistently performed best and most consistently, and sparse images (now dropped from Disk Utility’s options) fare worst, particularly when encrypted. Howard Oakley: Although most of the test results […]

Macro Arment (Mastodon): What’s in this beta: Transcripts of most podcasts (swipe on the episode art during playback, it’s a new page past the info screen) Live-scrolling of transcripts during playback Tap to seek on any line of text Music detection All of this should work even with dynamic ad insertion… and even with private/membership […]

Ryan Whitwam (Hacker News): With its new limits on sideloading, Android phones will only install apps that come from verified developers. To verify, devs releasing apps outside of Google Play will have to provide identification, upload a copy of their signing keys, and pay a $25 fee. It all seems rather onerous for people who […]

Hartley Charlton: Apple has quietly blocked AI “vibe coding” apps, such as Replit and Vibecode, from releasing App Store updates unless they make changes, The Information reports.

John Gruber (Mastodon): One might presume that the dedicated indicator lights are significantly more secure than the rendered-on-display indicators. I myself made this presumption in the initial version of my MacBook Neo review last week. This presumption is, I believe, wrong. Later last week Apple published, and I linked to, a small update in their […]

Random Augustine (2025, Hacker News, John Gruber): The kernel shared in common between iOS, macOS, tvOS, visionOS and watchOS — named XNU — is based on a microkernel called Mach. However, the way XNU has been implemented places all system functions within the same privileged scope and it effectively operates as a monolithic kernel. The […]

John Gruber: But where I think Amodei’s remarks, quoted above, are facile is that it hasn’t played out as simply that lines of code that would have been written by human programmers are now generated by AI models. That’s part of it, for sure. But what’s revolutionary — a topic I’ve been posting about twice already today — is […]

Howard Oakley: Apple has just released its first public Background Security Improvement (BSI) for macOS 26.3.1 Tahoe, labelled as BSI (a)-25D771280a.

Jeff Johnson: The older, simpler API [NSURL URLWithString:URLString] behaves the same as [NSURL URLWithString:URLString encodingInvalidCharacters:YES] when your code is compiled with the iOS 17 or macOS 14 SDK. So much for backward compatibility! [NSURL URLWithString:URLString] continues to work fine with example 1, leaving the URL string untouched, but it mangles example 2: https://example.org?url=https%253A%252F%252Fexample.org%253Ffoo%5B0%5D%253Dbar Notice that […]

Tim Cook (MacRumors): Fifty years ago in a small garage, a big idea was born. Apple was founded on the simple notion that technology should be personal, and that belief — radical at the time — changed everything. […] At Apple, we’re more focused on building tomorrow than remembering yesterday. But we couldn’t let this […]

Drew McCormack (February): Had my Core Data sync framework, Ensembles, pretty much in maintenance mode. With Apple moving on to SwiftData, didn’t seem any point to modernizing the 15 year old ObjC codebase. But I had the thought to give Claude a shot at it, and in 2 days I’ve got a complete port: Swift […]

Wade Tregaskis: Nobody else has even tried to make a bright 6k display – in fact, every non-Apple 6k display is outright dim by modern display standards – they’re barely brighter than the original 5k display in the 2015 iMac! […] For the price of one Apple Pro Display XDR you can get four Asus […]

John Gruber: By default, the MacOS accent color in System Settings → Appearance defaults to a color that matches the Neo’s hardware — a fun trick Apple has been using for decades. David Deller: This is the first I’m learning that System Settings sometimes has a special accent color only available to a Mac with a particular […]

Greg Knauss: What I am talking about is being replaced, about becoming expendable, about machines gaining the ability to adequately perform a very specific function that was previously the exclusive domain of skull meat. What I’m talking about is that nothing I do matters. That nothing I can do matters. In just the past few […]

Adam Grossman: Fifteen years ago, we started work on the Dark Sky weather app. […] We enjoyed our time at Apple. So why did we leave to start another weather company? It’s simple: when looking at the landscape of the countless weather apps out there, many of them lovely, we found ourselves feeling unsatisfied. […] […]
