I'm using an iMac Retina 4k, 21,5", 2017, with Catalina 10.15.4


I saw in another post that some terminal outputs would be helpful. Please see below.


Kind regards

You are supposed to have a Fusion drive, but you do not. If you have a backup of your current macOS installation, then look at How to fix a split Fusion Drive - Apple Support. If the steps do not work, we can rebuild the Fusion drive manually.
