and then take a look at Parental Controls in System Preferences.
This will enable you to tweak everything and only give him access to those things that you want him to have.
That includes LaunchPad
I am setting up an iMac with Mountain Lion for my son. He's just learning about computers and only uses certain apps. I'm obviously only putting what he would use in the dock but also I realized that LaunchPad just kind of throws everything in there. It seems it's possible to rearrange the apps/screens like on an iPhone. What I don't see is a way to remove certain apps from the Launchpad screens. It seems to even put some apps on there that are not even actual apps.
Is there anyway to remove items from LaunchPad? In a worse case if there isn't is it possible for me to remove LaunchPad completely from the system?
