I got a new MBP running Mavericks. I used Migration Assistant to transfer my personal data from old MBP (Lion) to new MBP. Everything seems to be working except for Mission Control. When I click Mission Control from Dock or press the Mission Control key (F3), nothing happen. I used Space on the old MBP and Mavericks has replaced Space with Mission Control. Is that the problem? Did my Space settings mess up Mission Control? How can I fix it?
