I am very skeptical of a new filesystem that is going out to users that fast. I haven’t tested the beta yet, but I would imagine we still have the option of using HFS+? Otherwise I’ll wait six months or more to even attempt it.

I hear you, but the FS has been silently deployed to millions of iOS devices already, so I'd imagine it's pretty well tested for them to bet customer data on it. I also haven't had any issues with APFS on 10.13 beta, but I haven't used it in any fancy way yet.

If you have an all-SSD Mac, the file-system will get converted during the upgrade. I think you still have the option to choose HFS+ when you perform a clean install.

Anyway: I installed the GM with an HFS+ boot volume that would fail an `fsck_hfs` (and when attempting to fix inconsistencies, it would get stuck indefinitely). Given the amount of bitrot I experience with HFS+ I welcomed the in-place conversion to something (hopefully) better and I'm surprised it worked so well.

If I'd like to stick with HFS+ for now, do I have the option to during the upgrade? I dual boot with Windows and I'm worried about something getting messed up and am not sure if there's a way to read APFS from Windows yet (I back up of course, but want to avoid potential issues)

Update: I upgraded, and everything happened automatically. No option to opt out of APFS conversion so yeah, if that effects your workflow you should know that. Went without a hitch for me though!

There is not any way to read APFS from Windows.

You do have backups, right?
