I have Yosemite, and my Keychain Access only shows the login keychain, giving me no option to switch between keychains.
As you can see, my sidebar on the left is missing. I try toggling it with ⌘+K, but to no avail.
Pressing that button repeatedly, thereby supposedly hiding and showing the keychain sidebar, doesn't do anything.
What might be the problem, and how can I fix it?
