I've got two Thunderbolt arrays that mount just fine. You might want to try to figure out if it is something that was adjusted so it doesn't show up where you expect. If you Go > Computer (cmd-shift-C), does it show up there?


You have to erase and reinstall macOS to the version you want. Getting it is a bit difficult.

You have to download it with softwareupdate in the Terminal, create a bootable USB installer, boot from that installer and erase/reinstall macOS. Then, migrate you data from your Time Machine backup.
