Apple Creator Studio and the App Store

Adam Engst: The transition from version 14.4 of Pages, Keynote, and Numbers to version 15.1 has been confusing, to say the least. In late January, Apple released version 14.5 of all three apps, with the App Store claiming “This update contains bug fixes and performance improvements” for all three. I wonder if even that is […]

Apple Creator Studio Icons

BasicAppleGuy: A comparison between the original icons, the pre–Creator Studio icons, and the non–Creator Studio icons. Adam Engst: I have to wonder whether the Numbers icon expresses the designer’s disdain for Liquid Glass or the community’s criticism of it. It looks like it’s giving the finger. Ezekiel Elin: I thought that the new Creator Studio […]

Retrocade 1.3

Craig Grannell (Mastodon): Still, I did write ‘Why I want Apple Arcade to include classic arcade games – and why that’ll never happen’. But now it has happened, thanks to Retrocade. And here’s the bit that genuinely surprised me: Retrocade is good to the point I think it’s the best entry point for normal people […]

Apple XNU: Clutch Scheduler

Apple (via Hacker News): The traditional Mach scheduler attempts to achieve these goals by expecting all threads in the system to be tagged with a priority number and treating high priority threads as interactive threads and low priority threads as batch threads. It then uses a timesharing model based on priority decay to penalize threads […]

NetNewsWire 7

Brent Simmons (2025): With retirement imminent — this is my last job, and June 6 is my last day (maybe I’ve buried the lede here) — I want to thank my team publicly for how they’ve made me a better engineer and, more importantly, a better person. Brent Simmons (Mastodon): I’m not retiring from writing apps — […]

Apple News Scam Ads

Kirk McElhearn (Bluesky, Hacker News): I use Apple News to keep up on topics that I don’t find in sources I pay for (The Guardian and The New York Times). But there’s no way I’m going to pay the exorbitant price Apple wants for Apple News+ – £13 – because, while you get more publications, […]

LLMs and Software Development Roundup

Colin Cornaby (Mastodon): Certain tasks have worked well for me. These tasks tend to fit the LLM model well. […] It’s probably not surprising that there is a relationship between the sunk cost fallacy and gambling. Gamblers get a huge dopamine rush when they win. Sunk cost fallacy feeds that. No matter how much they’ve […]

AEQuery

Mark Alldritt (Mastodon): I’ve released a new command-line tool called AEQuery. It queries scriptable macOS applications using XPath-like expressions, translating them directly into Apple Events. The short version: you describe what you want using a slash-delimited path, and AEQuery resolves the SDEF terminology, constructs the Apple Events, and returns the results as JSON. […] The […]

Time Machine in Tahoe

Howard Oakley: Time Machine had happily gone that long without backing up or warning me that it had no backup storage. […] I think this results from Time Machine’s set and forget trait, and its widespread use by laptop Macs that are often disconnected from their backup storage. […] If you do just set it […]

Accessing the Unified System Log From a Standard User Account

Rich Trouton: Using the log command line tool doesn’t require root privileges or require admin authorization, but it needs to be run by a user with admin rights. […] What this does is create a sudo configuration which allows all members of the staff group on the Mac, which is a group that has all […]

Tahoe SwiftUI Table Bugs

Todd Heberlein: The first bug report, FB21850924, covers a terrible memory leak in SwiftUI’s Table view, a feature our program uses a lot. […] Despite the rapid updates to the data, the sample program only keeps 1000 records in a deque, so the memory usage should bounded. Strangely, switching to another view triggers Swift to […]

Xcode 26.3

Apple (RC xip, downloads, Hacker News): Xcode 26.3 introduces support for agentic coding, a new way in Xcode for developers to build apps, powered by coding agents from Anthropic and OpenAI. With agentic coding, Xcode can work autonomously toward a developer’s goals — from breaking down tasks to making decisions based on the project architecture, […]

Testing Tip: Always Show Scrollbars

Marcin Wichary: This scrollbar serves no purpose, so it will become visual noise for a lot of your users. But when you yourself use “shy” scrollbars, you might not even realize. Of course, the scrollbar is just a symptom of a bigger problem – an accidentally scrolling surface that will be janky to everyone regardless […]

Tahoe NSTableView Scrolling Bug

Sarah Reichelt (Mastodon): [When] I scrolled down from the top, the content rows would scroll into the header, making the top messy and unreadable. This sort of overlapping and unreadable text is a feature of the various OS 26s, but in this case, there wasn’t a hint of transparency, so it looked like a bug […]

Sinofsky on Cook and Forstall

Richard Lawler: Emails released by the Justice Department on Friday appear to show that former Windows boss Steven Sinofsky not only consulted Jeffrey Epstein for help in securing his $14 million “retirement” package in November of 2012, but also in working on future career steps at other companies like Samsung or Apple. One document appears […]

The Fallen Apple

Matt Gemmell (Mastodon, Hacker News): Executives, experts, engineers, and designers are all leaving for more lucrative positions at even less scrupulous companies. Apple is currently the GUI laughing stock of the industry, a position once firmly held by Microsoft for decades, and the walking-back of poor decisions in followup point-releases has become normal. Liquid Glass […]

DFU Port on the 16-Inch MacBook Pro

Jeff Johnson: This [Apple documentation] is wrong, a discovery that took me about a half dozen attempts to update macOS on an external disk. I have a 16-inch MacBook Pro with an M4 chip, specifically an M4 Pro chip, and the DFU port seems to be the USB-C port on the right side of the […]

iOS 26.3: Limit Carrier Location Tracking

Juli Clover: Mobile networks determine location based on the cellular towers that a device connects to, but with the setting enabled, some of the data typically made available to mobile networks is being restricted. Rather than being able to see location down to a street address, carriers will instead be limited to the neighborhood where […]

Apple and Kakao Pay Fined Over Privacy

Proton’s Tech Fines Tracker (via Ben Lovejoy): While $7.8 billion in fines sounds substantial, it represents little more than a rounding error for Big Tech. Based on free cash flow, Alphabet, Apple, Meta, and Amazon could collectively pay off all 2025 penalties in just 28 days and 48 minutes. Alphabet alone — fined more than […]
