I have a MacBook Pro which has Leopard Mac OS X 10.5.8 and i want to upgrade this to Snow Leopard 10.6.2. Is it possible? If yes then give me some guidelines.

  • "iphone" is not an appropriate tag for this question. – Peter Murray Jul 7 '10 at 13:34
  • The one caveat I would add is "Don't pay too much"! ;-) I'm not sure what the best price currently is, but you can get a retail, 1 system 10.6.3 install DVD from eshop.macsales.com/item/Apple/MC573ZA for around $31 when shipped USPS. I suggest trying to get a version of the install DVD with includes as many "updates" as possible. It may make your install smoother and will save time by not having to download as large an update later. – irrational John Jul 7 '10 at 16:56

This really isn't the right forum for a question of this sort our sister site superuser.com would be. That said this is very easy; just buy 10.6 from Apple, backup your system, boot from the disk, follow the installation instructions then update your system once it's installed - it's that easy.
