… wants to use the "login" keychain.
Every time that I start up or restart my iMac, after I have entered my system admin password, a new login box appears which states that one of several applications wants to use the "login" keychain. These apps include CalendarAgent, iCloudHelper, Messages Agent, CallHistoryPluginHelper, and idmsa.apple.com.
I can dismiss the second password box but then immediately, a new box appears with another of these various apps requesting the same thing. Interestingly, I discovered that I can do screenshots of the 2nd login box. An example is shown below.
I've poked around the Keychain preferences and not found anything which suggested a solution. I've booked a Genius Bar appointment for Friday the 10th but maybe someone already knows the solution.
My wife's MacBook Pro does not do this. It must be something in some preferences or something needs to be reinstalled. But what?
iMac, OS X Yosemite (10.10.3), 27"
