Mac Os X operating system has different options to manage startup items. If you have already installed skype, some messengers, orb or some agents, you may not want to use them at the startup of your computer. To inactivate these processes, actually you should remove your login accounts related to corresponding process. So;
- You do not have proper access to edit the person’s account you are looking at.
- You have proper access, but you need to “Click the lock to make changes.” Just look at the padlock icon at the bottom-left corner of the page. If it’s locked, that’s what you need to do.
