Problem installing D2 on macbook

So I put in the CD and tried to run the installer.

Result?

"You can't open the application 'Diablo II Installer' because the Classic environment is no longer supported"

I just got my macbook a month ago, and it's my first experience with a mac, so I really have no clue how things work.

Help?

Well, I'm sure that it would have solved my problem. Unfortunately, China doesn't seem to have a positive opinion about the file...

Looks like I'll have to wait til I'm back in the States to download it.

Thanks for the help though.
