Searching for Apps With Spotlight

Brent Simmons: Spotlight has recently become terrible for launching apps after being so good for years. Now when I type something like Cal or Calendar or even Calendar.app I have to manually select the actual app in the list, if it even appears. I’ve never used Spotlight for this on macOS (preferring LaunchBar) but have […]

Versioning Your SwiftData Schema

Mohammad Azam: We started with a simple model. Then we added a new property and transformed existing data. Then we introduced a uniqueness constraint and cleaned up duplicates before enforcing it.

Juli Clover (release notes, security, enterprise, developer, full installer, IPSW): According to Apple’s release notes, macOS Tahoe 26.3 focuses on bug fixes and security updates rather than new features, so it is a smaller update than some of the other releases we’ve had.

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 […]

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.

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, […]

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
