Juli Clover, reporting for MacRumors:
iMacs with Fusion Drives were converted to APFS during the beta
testing process in the first macOS High Sierra beta, but support
was removed in subsequent betas and not reimplemented.
With the release of the Golden Master version of the software,
Apple has confirmed APFS will not be available for Fusion Drives
and has provided instructions for converting from APFS back to the
standard HFS+ format.
I have all-flash drives in both my MacBook Pro and iMac, but I’m not in any hurry to switch to APFS. And since drives that can be updated are automatically updated to APFS when you update to High Sierra, I’m in no rush to update to High Sierra. Don’t get me wrong, I’m looking forward to APFS. This just feels like something for which I’ll wait for 10.13.1.
