Bread-Bakers v112.n003.3

I used Mastercook on a Mac for years until Sierra bought it and 
destroyed it.  I haven't found a suitable alternative on the Mac, not 
yet.  My files are ancient, I would need to import them.  Any 
recommendations on Mastercook compatible software for the Mac?  I 
tried YUM but the developer sold it and then it was upgraded into uselessness.

Thanks,
Donna Marie
