Just a head up from a problem I ran into. When installing a USB Passport drive for the Mac, Finder didn't list it and Disk Utility did see it and was able to format it but then showed 100% full. Apple support helped turn my attention to ESET, and I found one of the upgrades by default enabled "removable media blocking," which prevented me from using the Passport drive or any other. Turning that setting off solved the problem.
Tip if your Mac stops recognizing your backup disk
in ESET Cyber Security Pro (for Mac)
