First, make sure you really want to. macOS’s screen saver system is absurdly buggy and broken. It’s frustrating to work with and very difficult to make work right. If you’re determined, read on. Screen savers are basically just applications. Same bundle format and structure, just with a “saver” extension instead of “app”. Setting up the… Read more
This post is mostly to herald a pretty good Apple bug report response, which as we know is a too-rare event. But it might also help others with this confusing SwiftUI API. What’s the difference between presentedWindowStyle(_:) and windowStyle(_:)? Well, one does something, the other doesn’t, basically. I tried using the former, and observed that… Read more
This is a public reposting of FB14885505, in case it’s helpful to anyone else or especially in case someone else has seen this too and knows how to work around it.

If you’re too young to have personally lived that time, just know this key point: back then, buying or streaming music online… Read more
This morning I tested out Apple’s Vision Pro in an Apple Store. And I’ve decided to write about it, mostly for my own future nostalgia, but also because my experience was markedly different to what’s been widely reported in tech news. I had intended to just buy an Apple Vision Pro on release day, but… Read more
