Till now, I've been the sole and proud owner of an iMac. I've always logged in as an administrator and I've also installed a bunch of software following the standard procedure of dragging and dropping it into the Applications folder.

This is about to change, as sharing it with a friend makes a lot of sense now that I only have time to use the computer in the mornings, and she can only use it at nights.

I thought this was going to be really easy: Just create a user account for her and that's all, I thought.

Unfortunately, this is not the case. When she logins into the computer using her username and password, she has access to the same applications I've installed. Even the same applications that I setup to automatically start when I login start for her when she does.

How can I setup a user that has only access to the applications that she has installed, but none of the ones installed by other users?

Many thanks
