Ok so i loaded on snow leopard and days later my hard drive crashed. so to be safe when i got a new hard drive i loaded my computer to normal leopard. i want to fully try snow leopard again to see if some of the up dates fixed some of my programs working but if not i want to be able to go back to leopard. and i know you cant down grade. but if i were to time machine right before i put on snow, if i wanted to go back would it work to wipe my hard drive and reload everything from that time machine back up that had leopard on it? or no? what is the easiest way for me to try snow and if i dont fully like it then go back?
