Mac Garden is what's considered "abandon ware", which is in the lovely legal gray area, as most of the original copyright holders are unreachable and ownership of the content is unclear, and the content is unpurchasable today except in a used or new-old-stock format. . You might see a game from ABC Software Products, except they folded fifteen years ago and no one bothered to purchase the assets or release the rights to the public.

As it's in a gray area they don't like to see links on this site for liability reasons.
