AVPlayer doesn’t provide a built-in way to fade in or out. I previously described how you achieve a video fade-in (or out) using general CoreAnimation layer animation, as part of making a macOS screen saver. Now let’s tackle the audio. I’m not certain what curve this implements, but to my ears it doesn’t sound quite… Read more
This is pretty rudimentary, but apparently our robot overlords need me to write this post because many of them suggested some truly bizarre approaches, some of which don’t work at all. If you’re using AVQueuePlayer, then just use AVPlayerLooper. Easy. But if for some reason you want to use AVPlayer specifically (e.g. you need to… Read more
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

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 FB14893699, 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 any view in the [active] window contains a Toggle – even one that’s disabled or hidden – then Continuity Camera (re. ImportFromDevicesCommands and… 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. NSPasteboard mutates itself simultaneously from the main thread and the global concurrent Dispatch pool, w.r.t. to its internal type cache. This is surprisingly trivial… Read more
Sometimes you just need to shove a round peg into a square hole. Sometimes that genuinely is the best option (or perhaps more accurately: the least bad option). I find my hand is often forced by APIs I don’t control (most often Apple’s APIs). e.g. data source or delegate callbacks that are synchronous and require… Read more
