Now that Mojave supports APFS in fusion drives, how can I create a fusion drive from scratch with my SSD and HD?

I have a Mac Mini with an 128 GB SSD and a 1TB HD, already updated to Mojave and using APFS since High Sierra. How do I integrate both in a fusion drive?

  • To setup fusion drive you have to reinstall the system. Boot into a installer, follow instruction in apple.stackexchange.com/a/70113/13455 to setup fusion drive then install Mojave on it. – aleung Nov 13 '18 at 11:08

    Those questions/answers are quite old. Do they really apply to Mojave still? – lpacheco Nov 13 '18 at 11:14
  • Create fusion drive -> convert the fusion drive to APFS -> install Mojave on it. The command to create fusion drive isn't changed on Mojave. – aleung Nov 15 '18 at 6:25
  • @aleung I think the question is valid. I read all kinds of horror stories from people who had a FIY Fusion Drive and who upgraded to MacOS Mojave and APFS. It doesn't seem to be easy or feasible. – Jean-François Beauchamp Feb 9 at 17:47
