No. MiniVend will not run on a Macintosh running System 7 or other ``Finder'' operating system. If some technically-oriented user would port it, or someone will give MiniVend's author a PowerMac, then it might. 8-)
MiniVend's *files* can be manipulated by any computer. As long as uploads/downloads of database source, pages, and configuration files are done in ASCII mode, there is no reason you can't edit them on your Mac. And with MySQL or other ODBC databases on your UNIX-based ISP, you can even directly interface to the database you use with MiniVend -- provided you have the scarce ODBC middleware needed for the Mac. But you must run it on UNIX or another Mac operating system. MiniVend does run on MkLinux, Linux PPC, and OS/X.
