When formatted in HFS+, those use CoreStorage to manage the constituent SSD and hard disk, and that made fscking in SUM a much bigger gamble. SUM started to get more tricky when Macs shipped with Fusion Drives. One important difference between SUM and Recovery Mode are the tools available to you: unless you mount your normal startup volume in Recovery Mode, the only command tools you can access are those supplied as standard in the Recovery Volume, and that’s a deliberately very small sub-set of what you normally have available.

It has been some years since I last did that, and – on this iMac Pro at least – I won’t be able to repeat it. It’s not that long ago that, every few days, I’d have to restart my Mac in single-user mode (SUM).
