Why this works ..... I think .... help?
As far as I can tell, is important that you have an Intel mac, not PowerPC (PPC), because the Leopard-only app is designed only for Intel processors and the Leopard OS.
The Leopard API, as Tersono said, is the interface through which a program interacts-Leopard adds a lot of new features and options, but the majority is the same as the previous
That seems to be the issue-they want to only have to design it for the Intel processor (and the Leopard API), which includes almost all Macs made in the last year and a half. I bought my MBP in the spring of '07, and it was a shiny new Intel version, running Tiger, but before they released Leopard.
But the sticking point is you can also run the 10.4.11 operating system under the older PPC processors, which means that EA would have to make a PPC version to say that it works in 10.4.11.
As far as I can tell, that's what's going on. I have an email out with the tech department of EA's support team asking what the real incompatibilities are with the Leopard API, but my hour or so of testing had no problems. I plan to go out and buy the actual game next week, and try to pull the same trick. I'll let you know how it works.
Am I right here? Anyone else able to offer some insights?
