I just upgraded to Snow Leopard and everything seems to be working fine (and fast ) except for System Preferences. Whenever I double click the icon on my desktop, it says I need to upgrade System Preferences and that I am currently using version 5.2. So how do I upgrade System Preferences? Edit: Never mind, I figured it out. The 6.0 version of SP was in the Applications folder, while it kept the 5.2 version on my desktop. Problem solved.
