Hey Guys, I have a question regarding new OS X installation such as Snow Leopard. Hopefully I am posting this in the right forum section because it may be a switcher type of question. What is the best way to install an OS upgrade like Snow Leopard, fresh or upgrade? This will be my first OS upgrade since switching back to Mac. In the PC world, I personally found it was best to reformat and install a fresh copy of windows to avoid problems. I will assume both types of installation will be fine but I would like to know what your recommendation is. Thanks for advice and help.
