Fritz, for example, will allow you to store a complete game plus
variations all at once. As you move through the game, you have the
option of either entering a variation or continuing with the main
line. When you enter a variation, you don't lose the main line, but
can go back to it, later.

Is there anything comparable to Fritz for the Mac?

I guess I could run Fritz via Parallels (although I would prefer to run
a native Mac program), assuming it will work okay like that. Any Mac
users out there who have tried this? Otherwise, what are you using?
