New Apple File System Coming in MacOS High Sierra Won't Work with Fusion Drives

So it seems this is a non issue, except for beta users who need to convert back to HFS+?

I don't see any details, but it would be interesting to know why it wouldn't work with fusion. Is there some feature breaking corner case that arises from some worst case platter latency? Perhaps the crash protection?

So the new APFS filesystem doesn't work on factory configured iMac 5Ks which are quite new still. Disgusting.

(Currently helping a friend recover data from his APFS fusion drive which started to panic on the last beta before learning it's not going to be supported)

At least it seems like it might be temporary:

> Apple says APFS will not be supported on Fusion Drives "in the initial release of macOS High Sierra," which suggests support could be added for Fusion Drives at a later date after lingering bugs are worked out.

High Sierra also does not allow backups with Time Machine to APFS formatted drives.
