I have a volume that I keep my home on as well as used it for a system backup. I no longer need to have a system backup on this volume and only need my /Users folder... So I thought I'd just go ahead and convert it today, but I got the following error: Error: -69546: Conversion to APFS of a macOS system volume is only allowed in the OS Installer Environment So my question is, what's the proper process to make the conversion tools no longer gripe about this? Do I simply rm all the other folders, etc. and then will the conversion tools understand that they can move forward with conversion to APFS or do I need to change the volumes around somehow on the drive?
