Hi, I am setting up Mavericks from scratch. I want to set up an Admin account that will only be used to administer the new machine. I want to set up 2 user privilege accounts that myself and my wife will use to do our work. Question: Do I need to be logged in to my Admin account to install Photoshop, Lightroom 5 and MS Office or should this be done from my user accounts? If we both want access to use MS Office do I need to install it in each user account? How should this be done? Thanks.
