Is it ? I checked your link and they separate clearly which features comes to which OS, here's how I read it : - Communication safety in Messages > "This feature is coming in an update later this year to accounts set up as families in iCloud for iOS 15, iPadOS 15, and macOS Monterey." - CSAM detection > "To help address this, new technology in iOS and iPadOS" - Expanding guidance in Siri and Search > "These updates to Siri and Search are coming later this year in an update to iOS 15, iPadOS 15, watchOS 8, and macOS Monterey." So while the two other features are coming, the CSAM detection is singled out as not coming to macOS. But ! At the same time, and I saw that after the editing window closed, the GitHub repo clearly states that you can get the models from macOS builds 11.4 onwards : > If you have a recent version of macOS (11.4+) or j

ailbroken iOS (14.7+) installed, simply grab these files from /System/Library/Frameworks/Vision.framework/Resources/ (on macOS) or /System/Library/Frameworks/Vision.framework/ (on iOS). So my best guess is, they trialed it on macOS as they did in iOS (and put the model there contrary to what I had assumed) but choose not to enable it yet, perhaps because of the rounding error issue, or something else. Edit : This repo by KhaosT refers to 11.3 for the API availability but it's the same ballpark, Apple is already shipping it as part of their Vision framework, under an obfuscated class name, and the code samples runs the model directly on macOS : https://github.com/KhaosT/nhcalc/blob/5f5260295ba584019cbad6...
