Sorry for the noob questions, but I recently purchased a new Mac Pro which came with iLife 09. My MBA came with iLife 08. I'd like to do a clean reinstall on my MBA and add the 09 apps. First, what's on what DVD? Is the OS on one DVD and all the bundled apps on the other or is there a mix of apps on both DVD's? One potential snag is that I recall reading somewhere that the MP install of OSX includes optimizations/support for Nehalem... would this screw up my MBA or would it ignore that stuff? Not sure what the best approach is... any advice would be appreciated. Thanks!
