it comes up with diff outputs:
FreeBSD: Version is 8
Linux: Version is 8
Mac OS X: Version is 134217728

download md2.c, md2.h, tris.md2 and then type "cc -o run md2.c" then "./run"
Any help would be very very very appriciated

And on to the problem...
The problem is that the file stores data on disk in little endian byte format, whereas Macs use a big endian byte format. Here's what happens:
The version is stored as a 32 bit number as this is the size of ints on most computers today. On a little endian machine, 8 when extended out to be 32 bits is stored as:
0x08 0x00 0x00 0x00
On a PowerPC machine (big endian), 8 is represented as:
0x00 0x00 0x00 0x08
Hence when you read that top number in, it is, in big endian format actually 134217728.
You'll need to come up with a way convert from little endian to big endian to read it on any big endian machine, such as SPARC, PowerPC, Motorola 680x0, or basically anything but i386/VAX/IA-64.
