Why are some apps already on my Launchpad and how do they know my user name?

Version 3

    Your company's IT administrator may have added a number of apps to your Launchpad because these apps are already provided to you by your company. In cases where IT created a user account for you, they populated it with your user name and password to make it that much easier to use.

     

    When your employment status or job title changes, the apps on your Launchpad might change automatically based on changes to your access and permissions.
