I was adding "Guest" account for my family/friends to use whenever they need to use my iMac.
But when they told me that the iChat and Yahoo Messenger wont open. What happened is that when they click either these applications on dock and they'd just unexpectedly quit everytime.
I deleted its .plist files and empty trash. But nothing worked. Any solution? A friend of mine said I can delete "Guest" account and re establish a new account. I knew I won't be able to use "Guest" account again unless I create a new different one.
Help. Thanks.
