Just got a new Macbook, my first Mac in 5 years, and I'm having trouble getting it to save my Wifi network information. If I remember correctly, I was able to connect to the network at the office with no trouble, but when I try to connect to my home network, I get the error in the title: A keychain could not be found to store "<network name>".
I then get the option to Cancel or Reset to Defaults. When I select Cancel, it connects just fine, but won't reconnect if I leave the house and return, or shut wifi off and turn it back on. If I select Reset to Defaults, a dialog box pops up asking for my login password, but I can't type in the box. I click on the text box, but typing does nothing.

The issue was resolved by removing the network from the list of Preferred Networks: System Preferences --> Network Preferences --> Advanced --> Find network and click "-" to remove from list of networks. After that I restarted the computer, and was able to connect and save the network without issue.
