I believe their main reasoning for not supporting AV1 would be the lack of hardware decoding on their chips. I doubt it. Apple Silicon is more than fast enough to decode AV1 in software. Sure, the battery life won’t be as good but there are other trade-offs that can be made. Their latest chips were developed before AV1 had gained enough traction to be concerned about. I suspect that future M2 and M3 and A-series SoCs will have hardware decoding for AV1 built-in. In the meanwhile, a future version of macOS Ventura and iOS 16 will have AV1 support; it’s just going to take a little longer. They probably want to roll it out simultaneously on iOS, macOS, tvOS, and iPadOS.
