Re: How can i update my Macbook to OS x 10.5 ????
Updates between major "point releases" (10.4 to 10.5) are paid updates. You can upgrade to minor point updates (10.4.1 to 10.4.2 or 10.4.11) by doing the software update, as D suggested... but to go to a major point update, you have to purchase the update. Prior to Mountain Lion 10.6.6), there was no Mac App Store, so you had to purchase a disk to do the update. I am not sure if they are available anywhere at this point.
