MasterCook is excellent software, but if you are a Macintosh user, think
twice. You can still find their Mac version on the shelves in some
stores, but it is several versions behind their Windows version and they
do not plan any updates. Sierra's website doesn't list the Mac version
for sale anymore at all, and they have not responded to Mac users'
requests to continue support. Not all the features are compatible
anymore when you share recipes across platforms - so beware!
