I somehow stumbled upon Mario is Missing Deluxe Mac OS ISO.
For old times' sake, I played it for you all.
For new times' sake, 60 FPS and HD.
The Mac OS version somehow has a lot of changes.
As far as I remember, the photograph didn't have such a calm voice in the DOS version, and the intro has suffered from some changes that made it more confusing. Mario also uses the lower pitched voices that were in the Deluxe DOS version but never used there.
I may try to finish the game and see if there's more changes...
Also, some music sounds either better, or worse. I don't know if I can rip them, considering how unfamiliar I am with Macs...
If anyone owns any Mac OS versions of other Mario Educational games, I don't mind having them.
