MacOSX: Manage Programs that Automatically Launch at Startup

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;

Open System Preferences (if it’s not in your Dock, you can go to  > System Preferences at the top of the screen)

From the System Preferences screen, click the “Accounts” icon under the “System” settings.

For each account, there is a “Login Items” tab where you can add and remove programs to automatically launch at startup. If you cannot edit your Login Items there it is one of two things:

• 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.
