Mac OS X version 10.6.3 Snow Leopard (Mac computer with an Intel processor required)

Mac will tell you that you need to purchase the entire box set to go from Tiger to Snow Leopard, YOU DON'T!!! I purchased this and it was the easiest install on my mac. Took about an hour and it restarted when it finished install and it was like a brand new computer running on Snow Leopard! Saved me 5 gb of space also. - Customer Reviews
