I've tried to install Mac OS Mojave on my Mac Mini (late 2012), but it has Mac OS Extended (journaled) as the file system on the main drive. This link is somewhat inconclusive and refers to retired documents.
So my question is two-folded:
- Can I change in-place from Mac OS Extended (journaled) to APFS on my boot disc (and can Mojave boot from APFS)?
- If not, how can I install Mojave on my Mac Mini (which currently runs High Sierra)?
Update: I've already tried upgrading, and it failed with a vague error message related to the file system upgrade (which I sadly can't recall).
