I have 'disabled' the guest account on my macbook pro running Lion via System Preferences Users & Groups. However the guest account still seems to appear as an option to login at start up and when switching users. I have never used the guest account for anything, and I have tried a system restore but the guest user has returned as before. How can I get rid of it? Thanks. edit: I also just enabled and disabled the account again - but the guest option still appears at startup offering a safari only restart for a guest user.
