upgrade from OS X 8.5 (Mountain Lion) to 10.13 (High Sierra)
Oh, and Jim. BACKUP everything to good ext HD.
When you upgrade, I see the installer apparently stall at about 75% of the way through. Think this is where the disk format is converted to APFS from HFS. I’m not sure you can stop this behaviour however, but consider it.
Oh, did I say BACKUP first? 🙂
