I have an external hard drive enclosure, which contains two 3.5'' HDDs in a Raid 1. Windows and Ubuntu are playing nice with it, however, my MacBook (13.2.1) does not recognize it. It isn't even showing up in the Disks utility, let alone in Finder.
The drive is formatted with exFAT, since NTFS is apparently read-only for MacOS.
I am very unfamiliar with MacOS, so please treat this as a total newbie question.
