Upgrading to Mac Snow Leopard

First of all, I have a few things that I needed to move from a journal to this blog so I could include screenshot. This will be explained in a minute. I work at the library and most of the computers I manage are Macs. Since the release of Snow Leopard, our department has been installing it our our iMacs and MacBook Pros. It seems really nice and faster at opening applications. One of the things I use my Mac for is for mobile development for the library. I've been working on an iPhone app for a couple months now, but since I upgraded to Snow Leopard, I can't get my apps to build in my iPhone simulator. I'm working on getting that up and running again.
