This article is about the apple; there is also the small town of McIntosh, Alabama

The McIntosh (Mac) is an apple cultivar with red and green skin, a tart flavor and tender, white flesh. It becomes ripe in late September. It is traditionally the most popular cultivar in New England, well known for the pink sauce unpeeled McIntoshes make. Many consider it a superior eating apple and well suited for applesauce, cider, and pies.

The McIntosh apple was developed from the trees in the orchard of John McIntosh near Dundela , in southeastern Ontario (near Williamsburg and Prescott). He transplanted wild saplings in 1801, which were nurtured and developed into commercial potential over the next few decades by his son.

Offspring include the firmer Macoun (a Jersey Black cross), Spartan apple (a Newtown Pippin cross), Cortland, Empire, Jonamac, maybe Paula Red, Jersey Mac, and others.

Jef Raskin, a computer scientist, is credited with naming the Apple Macintosh, a computer system, after the fruit.
