I am new to using a mac. I have a macbook os x that is about 3 years old. I enabled firevault recently. This computer worked great until I enabled firevault. When I try to log in it will not take my password. After multiple attempts it ques me to type in my firevault password. It then asks me to change my password. When I do this a window pops up and says " you are unable to log im to the user account at this time. I have read many threads with the same problem. All signs point to needing an update. I dont understand how I can do an update without logging in. I read something about logging in as a root, but the instructions are not simplified enough for me to understand. Does anybody know how to fix this problem and explain at about a third grade level?
