Another proprietary filesystem? I was really hoping they'd adopt ZFS fully.

ZFS on OSX was doomed the moment Oracle bought Sun.

If you want to know why, just contemplate the smoking wreckage of the Oracle/Google Java API lawsuit.

Shipping in 2017? So it won't even be ready for Sierra?

It's present as a developer preview in Sierra, but isn't the default filesystem and can't be used as the boot drive.

Which is probably how it should be. I'd rather not lose data to a new filesystem because Apple rushed the thing out without proper testing.

Just saw a comment in another thread, stating Apple had slipped in improving their Unix layer, and here comes this. New file system is not a joking matter: Microsoft failed to deliver their new FS; Linux took years to go from ext2 to ext3 to ext4, and btrfs is in forever testing; most of *BSD still use their old ones; zfs took decade to become mainstream...

The information currently is very scarce on this one, but I hope they would at least test it REALLY WELL.

I was excited to until I read the limitations section. Can't be used as the startup disk and doesn't work with time machine. Hopefully this with change in the next macOs release.

Sure, this is a developer preview. Final release in 2017 will surely make this FS the default.

Apple says they intend to open-source the file system in the docs. Open Source : "An open source implementation is not available at this time. Apple plans to document and publish the APFS volume format when Apple File System is released in 2017."

Source of the quote is this page:

https://developer.apple.com/library/prerelease/content/docum...

Releasing a new filesystem is already surprising. And they plan to open-source it. Huh.

Didn't Microsoft introduce ReFS with many modern FS features?
