"Keychain System cannot be found" After upgrading to 10.11.2 my laptop stopped connecting automatically to my WiFi network. When I manually select the network it connects, but then it pops up a dialog saying "Keychain System cannot be found to store {SSID}".

When I look at the Keychain Access app I see a System keychain, and it is located at /Library/Keychains/System.keychain. But there is also a directory /System/Library/Keychains/. Will moving the System.keychain file under /Library/Keychains/ to /System/Library/Keychains/ fix the problem?
What solved the issue for me was using First Aid on the Macintosh HD from the Disk Utility app:


Start Disk Utility
Make sure to select Macintosh HD and not the top level storage (which represents the physical disk). You want to fix the logical partition.
Click the First Aid button at the top of the window.


Hope that helps
