Upgrade available??
I am new to Apple computers. I have a used machine running OS X 10.4 and see that I would be benefitted by upgrading to at least 10.6 (to get Adobe Flash, among other things). Can I buy an upgrade to 10.6 or 10.7 or do I need to go all the way up to the newest version (lion?)?
Thx,
