I'm trying to reset my keychain (Yosemite 10.10.4).
- When I enter my wifi password I get "A keychain cannot be found to store my_wifi_sid"
- I click "Reset to Defaults"
- I get "Are you sure you want to reset your keychain? This will delete all your saved passwords, keys, and certificates. You cannot undo this operation" and click "Reset"
- I get "Please enter your login password. This password will be used to create your new keychain." with a password field. Attempts to type in this field interact with whatever app is in the background (browser, desktop). I can click the "Show password" checkbox.
This issue has also been reported at https://discussions.apple.com/thread/6788761. Upgrades did not help.
Deleting keychain folders via the command line ends up with the same result (not saving passwords and the above dialog). This started about a month ago and does not appear to be associated with any system update.
Any tips on troubleshooting, logs to look at would be appreciated.
tl;dr: disabling the Guest User and upgrading to El Capitan seems to have done the trick.
Not what I'd call an answer since I can't tell you which action is the fix, but here are two things, one or both of which may have solved my problem.
I tried to log into the Guest User on this machine and learned that somehow I got a not-managed Guest User account. This Guest User was asking for a password (which I did not know). So I disabled the Guest User account.
Disabling the Guest User account seemed to solve this issue for some (but not all) of the users. Next I downloaded the El Capitan installer to a thumb drive and installed it on my MacbookPro. Now all of my keychain issues appear to be fixed.
