While I was waiting to see the Mac Genius about my MacBook Pro, I called up KeyChain Access and got a very strange screen when I clicked on “Show Password” (as shown in the upper pane in the attached graphic). In the lower pain, rather than wanting my machine password (as one would expect), it only seems to take the password in question, in this case that for Amazon. As you can see, the lower pain is gobbledygoop as well. I’m a little worried that the machine may have been compromised via public WiFi at Apple or via some other means, though I do run AntiVirus software. Anybody have an opinion about what has happened here? I am running the beta of 10.10.4 but I upgraded today to the most recent beta and the problem remains.
