Hey! I'm trying to split a Fusion Drive. Note I've heard the warnings; no need to advise me against it. I know what I'm doing and I have backups of everything if things go horribly wrong. Anyhow, I am following this article which states to type 'diskutil coreStorage list' into terminal while in recovery mode, and it'll output a long string of details including a UUID you need for the next step. Problem is that I simply get a 'No CoreStorage logical volume groups found' return message. The computer is a 2012 iMac with a 1TB fusion drive, running 14.2. I got shunned away over on the Apple community forums saying I shouldn't be doing this, so I'm trying here. Thanks for reading, any help is greatly appreciated!!
