Some students are having difficulty with pop-up boxes asking for a keychain and no matter what students do or password they provide the popup box does not go away.
To solve this problem the students must delete their keychains and restart their computers. To do this please check out this video.
When they restart their computer they may have three options (see image below). They must select “Create New Keychain”
This should solve the problem.
Another way to really deal with it is open up Keychain (spotlight) click on login, and then press delete—delete the lot, reset and start again. You know all your passwords.. right?
