I've got a 17" MacBook Pro on OSX 10.5.7 and a 15" TiBook on OSX 10.4.11. Can I connect the TiBook to the MacBook Pro in such a way that I can use it to extend the screen? IE: main window on MBP and menus etc on Ti? If so how? Is it easy to switch back and forth on the Ti so I can get back to it's own screen easily? Thanks.
