Trouble deleting Boom2Device
I thought I had deleted Boom2Device, but traces of it still remain. It's not in my Applications folder, and it doesn't appear on the Activity Monitor list, but "Find Any App" found it in 15 places. As if that's not bad enough, when I started trying to delete those 15 files one-by-one, this notice appeared on my screen: “Boom2Device” can’t be modified or deleted because it’s required by macOS.
What??? Is that the final word? What's going on?
