Hey guys, I've got a MacBook, MacBook Air and 3 iMac's that all need to be set up so that they run similar to the Mac's in the Apple Store. I need them to run so that someone can use one of them, then the Mac automatically resets itself, getting rid of any changes the user has made, so when the next person uses it, they get a 'fresh' machine to try out. If this isn't possible, could I set it up so that the Mac's reset when booting up, so the previous days changes are removed? It would also be great if I could setup all of the programs and files that I want on all of the machines on the first machine, then somehow easily get that exact setup onto the other machines. Any help would be much appreciated. Cheers, Nathan.
