Keychain got deleted!
My keychain on my MacBook Pro (2014 or 2015) got deleted. Yes, the program 'Keychain'. Is there anyway to add that back to my System Preferences? I keep getting pop-ups and want to throw the computer out the window. Without the keychain, I cannot store my passwords. Any ideas how to add it back to my computer?
MacBook Pro 15″, OS X 10.10
