If you’re planning to reinstall OS X or move all your data over to a new account after hearing about how an OS X installer package can gain root access without a password, then don’t. There’s an easy way to turn your admin account into a standard account that is detailed on Mac Geekery. The steps are as follows (taken from the Mac Geekery post):

• Make a new user. Call it admin (or flyingmonkey, whatever).
• Make it an admin.
• Logout or FUS to the new admin user and strip your user of administrative rights.
• Logout of the new admin.

This exploit/feature is also discussed by Adam Knight on this week’s Mac Break Weekly.
