I got a refurbished Mac laptop from what I was told was a reputable site. Sadly, I cannot update any software because it wants a password for the administrator account. The account is user, but I cannot guess the password. The OS is 10.5.8. Thanks.
Thanks. I really would like to just be able to upgrade the software without spending more money.
I have a very similar problem, got a MacBook Air 11.6 1.6GHz 2GB 64GB SSD MC968LL/A OS X version 10.7
Use Recovery Mode
A final option for resetting your password is to use Apple’s recovery tools. This will perhaps be the easiest approach in most cases, and can be done with the following procedure:
Reboot into Recovery mode or Internet Recovery by holding Command-R at startup.
Choose Terminal in the Utilities menu.
Enter resetpassword (all one word, and lowercase) in the Terminal window and press Return.
Select your boot drive in the utility that appears.
Choose your user account from the pop-up menu.
Click the button to reset the account’s password and supply a new one when prompted.
You need to get a friend to make you a USB thumb drive installer, then erase the drive and install the new OS.
