I have just upgraded to El Capitan and after connecting Passport it is not visible in Finder, but I can feel the drive is rotating. In Disk Utility I can see WD Unlocker, but when I click “mount” nothing happens.
Too bad, because I cannot even revert to Yosemite, as Passport is my backup disk.
Don’t panic.
In the worst-case scenario–if nothing else ultimately works–there’s always the option of installing a new copy of Yosemite to a new disc and then accessing your backups on the Passport.
