It is not really so.


I have a similar model computer, and High Sierra installed. "macOS High Sierra introduces APFS (Apple File System) to Mac computers. APFS replaces Mac OS Extended (HFS+) as the default file system for solid-state drives (SSDs) and other all-flash storage devices."


APFS will not be installed on your Fusion Drive.

Yes, How to download macOS High Sierra - Apple Support lists compatible hardware.


You should also consider using RoaringApps to help you determine software compatibility.


Upgrading macOS without fear by John Galt is also a good source of information.

Thank you so much. I have searched your suggestions but found no answer.

FWIW, I have High Sierra installed on two iMacs with Fusion drives and it works just fine.
