I did not get a Mac until Panther was released, but I am sure the consensus is that Cheetah was a beta/RC and Puma was the first “true” version of OS X. Theoretically, you could go to 10.4982734000, the “four billion, nine hundred eighty-two million, seven hundred thirty-four thousandth” minor release of major version 10. After 10.9 comes 10.10 (not to be confused with 10.1), if they choose to stay on the same major. We will see after Mac OS X 10.9 who is right 😉 (th22)
