Hi, Late 2015 iMac i5 3.2Ghz 5K 32GB 1TB Fusion I really need help with this. I've been having issues with kernel panics on macOS Mojave. I couldn't boot into Recovery nor Internet Recovery (Both would end in Kernel Panics). Yet no issues were detected in a disgnostics test. And so I created a bootable Mojave USB Drive from my housemates Mac to do a fresh Mojave install. However, when I was able to boot into Recovery by holding down the Option key at boot and selecting the USB Drive, then selecting Disk Utilities I saw this: It appears as though the Fusion drive has split (Container disk0 and disk1), or am I incorrect? (edit: I was incorrect, please see further down the page, it appears the drive may have unmounted) I ran First Aid on Container disk2: "Running First Aid on "Container disk2" Repairing storage system Performing fsck_apfs - y -x /dev/disk0s2 Checking the container superblock. Checking the EFI jumpstart record. Warning: Could not iterate gbitmap tree to read reaper objects (old 0x18a36c) : 22 The volume /dev/disk0s2 could not be verified completely. Storage system check exit code is 0." I tried to reformat the drive but I couldn't: So, I opened Terminal and ran the # diskutil list command: Then I tried # diskutil cs to try to create a coreStorage Group, first I tried 'list', then I tried 'create'. As you can see I am not able to create a coreStorage Group as there is nothing mounted, and of course now at boot up there's no Mac HDD displayed for selection only the USB Installer. So, I'm not sure what to do now. I want to: 1. Re-join the disks; and 2. Fresh Install of macOS Mojave Any help is honestly appreciated. Thanks.
