How Can I Lock My Mac OS Apps Plsss Help!!!

HI Thomas,

To my knowledge, it's not possible to "lock" or password protect Mac OS X applications.

However, you could set up another user account so that anyone with access to your computer could only access files on that account not your admin account.

may I ask why you want to do this? applications themselves contain no user data at all. why would you want to password protect them? or is this a parental controls issue? you can enable parental controls on some accounts and restrict which apps can be run on those accounts.

"...You know sometimes you might just forget to log off or shut down before leaving. I have room mates that are not family so I'm just being more careful here."

If that's the case then be careful and shut down. (And take your MacBook with you).

You can also set your MacBook to require a password on waking from sleep and coming out of the screensaver--and set sleep or the screensaver to activate after a very short period--so that if you forget to log out your roommates cannot access your files. The Security pane in System Preferences is where you can require the password; the Screen Saver and Energy Saver panes allow you to set the timing for those features.

And if you don't trust your roommates, you may want to start looking for a new place ...
