The McIntosh (Mac) is an apple cultivar with a tart flavor and tender, white flesh, a superior eating apple and well suited for apple-sauce. It comes ripe in late September. It is traditionally the most popular cultivar in New England, well known for the pink sauce unpeeled McIntoshes make.

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.

The brand of personal computers named after the apple by Jef Raskin is spelled Macintosh.
