Anybody who can give a hint on the following issue. I want to take my iMac 2.66 MHz early 2008 model from Leopard 10.5.8 to Mountain Lion. According to Apple webpage I need to upgrade to the latest version of Leopard before i can jump do Lion which is the 10.6.8. The install program of this ver 10.6.8 does not start and gives a message that I need to upgrade first to 10.6.0. I cannot find this version anywhere. I will appreciate any help on this.
