Does anyone actually know for sure if Apple ever updated the APFS preview code since WWDC seed? I feel like we're like 2-3 years behind of Apple right now on the status of APFS for macOS. The fact that it's booting right now on iOS devices with 10.3 Beta with zero issues should tell us that the current APFS build at Apple is already way ahead of what we know about it and Apple did announce that all platforms will be using APFS this year. So I'm wondering if they're going to release the final preview in 10.12.x at all or it'll be in 10.13 and auto-converted like iOS 10.3.
