How do I split Fusion drive on Mojave / APFS?
I have a 2013 iMac that has a Fusion drive. I want to replace its internal HDD with an SSD. My understanding is that I should split the Fusion drive before performing this.
I referred to the article https://www.macworld.com/article/2015664... which discusses the use of diskUtil and Core Storage to get the GUIDs and split the drive.
However, invoking disktutil coreStorage list returned ‘No CoreStorage logical volume groups found’. I then tried diskutil list, which returned more information, apparently showing the fused drives as ‘synthesized’. I read a bit about this in other discussions, and it seems like this is perhaps a Mojave/APFS version of a Core Storage Fusion config.
I’m wondering what I need to do to split my Fusion drive. Is there something else to use, or do I not even need to split the HDD/SSD before replacing the HDD?
I wonder if I need to downgrade it to High Sierra, and setup the drive as HFS?
Es esta una buena pregunta?
