I am having a problem with MYM for MACintosh.

I only deal with the DOS version of MYM, but I think you can install MYM if you go to "Classic OS" mode and install from there. I’ve talked to some Mac owners and it seems the best way to go about this is finding a copy of the Mac MYM version 7.2. Try the MYM forum at http://go.compuserve.com/Money for help since I've forwarded other MYM MAC users to this forum as well. Hopefully, you can find a thread there with MYM MAC users that can offer some advice.
