You don't have permission to use the application "CredentialStore"
I set up a child account on my MacBook however when I login into the account for the first time the error message comes up with options okay? Allow once allow always if I select okay? It comes up again if I select once it asks for an administrator username and password, but it won’t allow me to enter the details because as soon as I click into, the username field it flips back to the error message. I persevered however and found that if I was quick I could type one letter at a time I did this until I finally got my username and password entered and pressed okay. Thing happened for the next application that the computer wanted to use this time I did the same thing but I copied my username so that I could just , paste it in. I had to do this about 10 times for about three or four different applications and now finally the error messages have gone away.
