  • OpenCore and Hackintosh are sadly dead after Apple ends Intel Mac support

    Why wouldn’t Hackintosh folk just shift to ARM64-based PC’s? How much of the instruction set is beyond ARM64 and can’t be compensated for? We should be hearing about macOS 27 on Raspberry Pi 5. 🤣

  • Which Bluetooth devices you can use with Apple Vision Pro

    Has anyone investigated the availability of 20-bit/48kHz lossless audio with the AirPods Pro 2 USB-C when used with the Vision Pro yet? Is it available now? Do you see anything in the UI about it?

  • Why the new AirPods Pro 2 are needed for Apple Vision Pro lossless audio

    For the wireless connection, Huang didn't specifically say they are running Bluetooth at 5 GHz.
    To quote the article: "Huang also says that this increased Bluetooth bandwidth". It was the article I was criticising. I haven't checked the video to see if he does say this.

    The bit depth can be whatever size, it's just a data encoding same with color. 16-bit = 65536, 20-bit = 1.04m, 24-bit = 16.7m, each increase is 16x more info.

    The lossless wireless method doesn't need to be compatible with Bluetooth, both the Vision Pro and Airpods will have special chips that can send this kind of data and other devices with revert to Bluetooth without lossless.
    If you understand currently popular audio formats and codecs, it's a moot point to say that bit depth can be whatever size because this isn't the concern. When you choose a format which is not matching the source then you have to transcode. Transcoding costs time/latency, energy and generates heat. Either the transcoding cost isn't a major concern to them or they intend to have everyone, making audio for the Vision Pro, make it to this specification. This could also include adding a 20-bit/48kHz prepared file of every track in Apple Music. All to avoid the additional transcoding cost. It is not a common audio format today and most audio software will not currently include this configuration in its standard UI. I want to know the rational behind this decision they've made. Why didn't they just opt for 16-bit/44.1kHz, if 24-bit/44.1kHz (most common lossless format on streaming platforms) was too big. It's like some kind of middle ground. Everything needs transcoded but it's less work to get from each of the common formats to this middle ground. That's all I can think of right now.

    I certainly didn't say it needed to be compatible with Bluetooth. As per above, the article associated the reference to 5Ghz with Bluetooth. As I said, Apple can't just transmit whatever it likes over 5Ghz. It must be registered with many authorities worldwide, if it is not an existing standard.

    20-bits? Where did that come from? I’d get 24-bits as that’s what most major artists release their lossless tracks in, but 20-bits? That’s a weird downscale. They’d be better off running with 16-bits. I could see them doing 24-bit/48Khz as most content is either 24/44.1 or 24/48. But nothing is 20/48. Is that a typo?

    There is no 5Ghz Bluetooth. It has to be something else, e.g. Wi-Fi or something entirely proprietary. They’ve cleared added a 5Ghz radio to the revised H2 but it can’t be Bluetooth unless they’ve got a world exclusive on a future version of Bluetooth… and that would be huge news. Anything they do with any radio frequency must be publicly declared. 5Ghz is primarily reserved for Wi-Fi. I’d need to research to discover if any other protocols are approved to use it. They appeared to hint at some new protocol. I still suspect it has to be piggybacking on an existing standard or they’d have to have declared it to the FCC and other similar authorities before shipping. They could be using some sort of ah-hoc peer-to-peer 5Ghz Wi-Fi.

    It depends what they’re doing… saying the H2 specialises in audio and somehow that prevents the tech in the current iPhone from also doing it, doesn’t make sense. Digital Audio is still 1’s and 0’s. I can’t believe they’d only deliver lossless on the Vision Pro. That’s too niche. We’re crying out for it on everything else.
