Hello I have a maverick macbook air.
Previously It was another user pc. I can access to his session.
I have updated to maverick correctly, and I have installed several app correctly.
My problem is when I try to update the imovie, the system ask me to log with the first user's apple Id. I can change the apple id in the first user setting ( I have set my own apple Id in this user).
If I install another app I can log with my apple Id, but If I want to update an app (like imovie or iphoto It shows the old apple id and doesn't able to change it.
