Mac App Store Search Not Showing Mac Apps

Jeremy Provost: When you search for Morpho, the App Store automatically flips you over to iPhone & iPad Apps, even though there’s a perfectly good Mac app that matches the search.

Mac App Store Design in Tahoe

Tony Arnold: The attention to detail in Apple’s App Store app is just… not there. I draw your attention to the “Available on” subtitles below each app in the grid — they’re inconsistently truncated, some not even indicating that they are truncated. The spacing and padding also seems to be “best efforts” (check the device […]

App Store Comparison Shopping

Jeff Johnson (Mastodon): Hot on the heels of my previous blog post My collected App Store critiques, I have yet another critique. It’s undoubtedly old news to many people, my critique coming years too late, but in my defense, I almost never shop for apps in the App Store. Rather, I merely download apps in […]

Swift Testing With Event Streams

How to Replace Time Capsule

Howard Oakley: Tahoe no longer lets you start a new backup on a Time Capsule, nor it appears to any other store requiring HFS+ (Mac Extended) format. Time Capsule support is expected to end with macOS 26 Tahoe, as macOS 27 is unlikely to support AFP any more, so those Intel Macs compatible with Tahoe […]

TextEdit Love

Kyle Chayka (Hacker News): What I’ve accrued the most of by far, though, are TextEdit files, from the bare-bones Mac app that just lets you type stuff into a blank window. Apple computers have come with text-editing software since the original Mac was released, in 1984; the current iteration of the program launched in the […]

That complaint continued through the release of the second-generation Vision […]

Building Zavala 4.0

Maurice Parker: Adding data syncing to any application is hard. iCloud helps with that somewhat, but it is still really hard to get right.
