APFS Questions

[Ray2]

I just started a fresh install from El Capitan to Mojave on an optioned out 2014 MBP. Not smooth but issues, so far, were Dropbox and 1Password related.

I have a 2 partion spinner I loaded the Mojave install on. I do not see the Mojave partition in Finder when I boot from El Capitan. Is this normal? (I do see the partition when I boot holding down the option key).

If I clone the Mojave partition back to the internal, will it be APFS or do I need to do something to the internal first?

El Capitan ignores APFS partitions, so you won’t see them when running El Capitan.

Before upgrading our Mini from El Capitan to Mojave, I did a clean install of Mojave on a 128GB micro SD card. The Mojave installer converted it from HFS+ to APFS. After installing key 3rd party apps & testing I cloned this now-not-so-clean install of Mojave onto the System partition of our Mini’s spinner using Carbon Copy Cloner. FWIW before I cloned Mojave, I booted from an SD card with a clean install of High Sierra* and used the HS Disk Utility to erase & convert the HDD’s system partition to APFS. I don’t know if that was necessary, but it worked

*I keep an SD card with a clean install of every OS that our Macs can run.

Thanks. Best I can tell, the correct way is to convert to APFS first then clone an HFS system to it. What you did. What I'll end up doing.
