APFS Is Not Optional (apple.com)

Posted by msmash on from the of-course dept.

From a new Apple knowledge base article: When you upgrade to macOS High Sierra, systems with all flash storage configurations are converted automatically. Systems with hard disk drives (HDD) and Fusion drives won't be converted to APFS. You can't opt-out of the transition to APFS.

    Yeah, I know: filesystems take a long time to mature and not lose data. You want your FS tested — widely — before you rely on it to not eat data.

    Here's the thing: iOS 10.3 included an upgrade to APFS. Since March, every updated iPhone and iPad has been running this in production. Most of them have no idea, because it's basically invisible. I haven't heard of any problems stemming from this change.

    So, while OS X has different (more variable, probably) use cases from the sealed systems in iOS, it's very likely that in "normal" usage, APFS is going to be reliable for folks.

    Only problem I can think of is that the drive may be inaccessible by other file systems.
    If the OS breaks down for some reason, this may make recovery of data a serious issue.
