Ok now I'm using an emulated Mac with OS 7.5.5 Now my question is this. When they go up a whole number (7.0, 8.0, 9.0, 10.0 etc.) what does that mean? I mean 10.0 moves up and names the OS something different like Jaguar, Panther, Tiger etc. Why doesn't it update to like version 11 or 12? Just curious, I use a program called Dev-C++ and they like do the same thing, when patches come out for it it updates the version (right now its 220.127.116.11 I think) but when it moves up to 18.104.22.168 they hope ot have better things integrated like the new MingW and that. But why does Mac not just go up whole numbers because they're basically new operating systems.
