I bought an old Mac from a friend, but her administrator user name & password information is still on the computer. How do I change the administrator name and password?
I bought an old Mac from a friend, but her administrator user name & password information is still on the computer. How do I change the administrator name and password so I can start downloading things to my computer? IMPORTANT: This is not my iCloud information. This is the computer's administrator information.
