TheMcIntosh (/ˈmækɪnˌtɒʃ/MAK-in-tosh),McIntosh Red, or colloquially theMac, is acultivatedapple variety, designated the national apple of Canada. The fruit has red and green skin, atart flavor, and tender white flesh, which ripens in late September. An all-purpose apple, the McIntosh may be eaten raw, cooked, or used to make apple sauce.
John McIntosh discovered the original McIntosh sapling on hisDundela farm inUpper Canada in 1811. He and his wife cultivated it, and the family started grafting the tree and selling the fruit in 1835. In 1870, it entered commercial production, and became common in Ontario, Quebec, New England, and New York after 1900. While still produced in large quantities, the fruit's popularity fell in the early 21st century in the face of competition from varieties such as the Ambrosia, Gala, and Honeycrisp.
Jef Raskin, an employee atApple Computer, named theMacintosh computer line—later abbreviated to "Mac" in 1999—after the cultivar.
The McIntosh, or McIntosh Red (nicknamed the "Mac"),[1] is the most popular applecultivar in eastern Canada and the northeastern United States. It also sells well inEastern Europe.[2]
A spreading tree that is moderately vigorous, the McIntosh bears annually or in alternate years.[2] The tree is hardy to at leastUSDAHardiness zone 4a, or −34 °C (−29 °F). 50% or more of its flowers die at −3.1 °C (26.4 °F) or below.[2]
The McIntosh apple is a small to medium-sized round fruit with a short stem. It has a red and green skin that is thick, tender, and easy to peel. Its white flesh is sometime tinged with green or pink and is juicy, tender, and firm, soon becoming soft. The flesh is easily bruised.[2]
The McIntosh is a general-purpose apple; it is suitable both for eating raw and for cooking.[3] It is used primarily for dessert,[2] and requires less time to cook than most cultivars.[4] It is usually blended when used for juice[2] orcider.[5] It could also be used to makeapple sauce[6] andapple pie.[5]
The fruit grows best in cool areas where nights are cold and autumn days are clear; otherwise, it suffers from poor colour and soft flesh, and tends to fall from the tree before harvest. It stores for two to three months in air, but is prone toscald, flesh softening, chilling sensitivity,[2] andcoprinus rot.[7] It can becomemealy when stored at temperatures below 2 °C (36 °F).[8] The fruit is optimally stored in acontrolled atmosphere in which temperatures are between 1.7 and 3.0 °C (35.1 and 37.4 °F), and air content is 1.5–4.5% oxygen and 1–5% carbon dioxide; under such conditions, the McIntosh will keep for five to eight months.[7]
The McIntosh is most commonly cultivated in Canada, the United States, and Eastern Europe.[7] As of the 2020s, most of Canada's McIntosh came from Quebec and Ontario.[9]: 38 South of the border, more than two thirds of McIntosh apples were harvested in New York State.[9]: 20 It is one of the top five apple cultivars used in cloning, and research indicates the McIntosh combines well for winter hardiness.[7]
If unsprayed, the McIntosh succumbs easily toapple scab, which may lead to entire crops being unmarketable. It has generally low susceptibility tofire blight,powdery mildew,cedar-apple rust,quince rust, andhawthorn rust. It is susceptible to fungal diseases such asNectriacanker,brown rot,black rot, race 1 ofapple rust (but resists race 2). Furthermore, it is moderately resistant toPezicula bark rot andAlternaria leaf blotch, and resists brown leaf spots well.[7]
The McIntosh is harvested in the middle of September, roughly at the same time as the Gala and Honeycrisp.[10]
The McIntosh is one of the most common cultivars used in apple breeding; a 1996 study found that the McIntosh was a parent in 101 of 439 cultivars selected, more than any other founding clone.[a] It was used in over half of the Canadian cultivars selected, and was used extensively in the United States and Eastern Europe as well. But rarely was it used elsewhere.[11] Offspring of the McIntosh include: theMacoun (with theJersey Black), theSpartan, theCortland (with theBen Davis);[12] theEmpire (with theRed Delicious);[13] the Jonamac, the Jersey Mac,[14] the Lobo, theMelba, the Summered, the Tydeman's Red,[7] and possibly thePaula Red.[14]
Apple trees were introduced to Canada at theHabitation at Port-Royal as early as 1606 by French settlers. Following its introduction, apple cultivation spread inland.[15]
The McIntosh's discoverer,John McIntosh (1777 – c. 1845–46),[1] left his nativeMohawk Valley home in New York State[16] in 1796[15] to follow his love, Dolly Irwin, who had been taken toUpper Canada by herLoyalist parents. She had died by the time he found her, but he settled as a farmer in Upper Canada.[17] He married Hannah Doran in 1801, and they farmed along theSaint Lawrence River until 1811,[b] when McIntosh exchanged the land he had with his brother-in-law Edward Doran for a plot inDundela.[c][1]
While clearing the overgrown plot, McIntosh discovered some apple seedlings on his farm.[19] Since the crabapple was the only native apple in North America before European settlement, it must have had European origins. The Snow Apple (or Fameuse) had been popular inLower Canada before that time; the seedlings may have sprouted from discarded fruit. Fall St Lawrence and Alexander have also been proposed, but the parentage remains unknown.[2][19] He transplanted the seedlings next to his house. One of the seedlings bore particularly good fruit.[1] The McIntosh grandchildren dubbed the fruit it produced "Granny's apple", as they often saw their grandmother taking care of the tree in the orchard.[20] McIntosh was selling seedlings from the tree by 1820, but they did not produce fruit of the quality of the original.[1]
John McIntosh's son Allan (1815–1899)[1] learnedgrafting about 1835;[15] with this cloning, the McIntoshes could maintain the distinctive properties of the fruit of the original tree. Allan and brother Sandy (1825–1906), nicknamed "Sandy the Grafter", increased production and promotion of the cultivar.[1] Earliest sales were in 1835, and in 1836 the cultivar was renamed the "McIntosh Red";[d] it entered commercial production in 1870. The apple became popular after 1900, when the first sprays forapple scab were developed.[2] A house fire damaged the original McIntosh tree in 1894; it last produced fruit in 1908, and died and fell over in 1910.[1][19]Horticulturist William Tyrrell Macoun of theCentral Experimental Farm inOttawa is credited with popularizing the McIntosh in Canada, praising it as "one of the finest appearing and best dessert apples" available at the time. TheMacoun, a hybrid of the McIntosh andJersey Black grown by the Agricultural Experiment Station in Geneva, New York, was named for him in 1923.[1]
The original tree discovered by John McIntosh bore fruit for more than ninety years, and died in 1910.[15] Horticulturalists from theUpper Canada Village heritage park saved cuttings from the last known first-generation McIntosh graft before it died in 2011 for producing clones.[18]
During the twentieth century, the McIntosh was the most popular cultivar inEastern Canada andNew England; it was also widely sold in the United Kingdom.[21] The McIntosh made up 40% of the Canadian apple market by the 1960s;[22] and at least thirty varieties of McIntosh hybrid were known by 1970.[1] However, its market share declined to 28% in 2014[21] and is expected to continue to do so, in part due to production cost and in part due to consumers favoring sweeter, crisper, and less tart apple varieties.[23][24] Its popularity has also waned in the face of competition from imports; in the first decade of the 21st century, the Gala (imported from Chile or the United States) accounted for 33% of the apple market in Ontario to the McIntosh's 12%,[24] and theNorthern Spy had become the preferred apple for pies.[25] Production remained important to Ontario, however, as 30,000,000 kilograms (66,000,000 lb) of McIntosh apples were produced in 2010.[24] In Nova Scotia, apple orchardists reinvigorated their businesses during the late 2000s by replacing McIntosh and Cortland with newer varieties that brought in more money per bin, namely theAmbrosia,Gala, and especially theHoneycrisp.[26] In Quebec, about two fifths of all apples harvested were McIntosh, as of 2020. Production remained relatively high in part because many orchardists were at the end of their careers with no successors, and as such were not keen to replace the McIntosh with newer varieties.[23] A significant portion of McIntosh apples harvested in Quebec was sent for processing while the average retail price of a McIntosh was only a third that of a Honeycrisp.[23] Nevertheless, the McIntosh is unlikely to disappear in the foreseeable future due to persistent residual demand for legacy varieties.[27]
In the United States, the McIntosh was one of the most produced apples during the twentieth century, behind only theRed Delicious and theGolden Delicious.[28] In the Northeastern United States, the McIntosh replaced manyBaldwin trees that were killed in a severe winter in 1933–34.[2] The McIntosh become the second most popular variety in the 1970s, after the Red Delicious.[28] According to theUS Apple Association, it remains one of the nine most popular apple cultivars in that country, as of 2025.[29] By the 2020s, however, total production of the McIntosh, measured inbushels, has fallen behind that of a new variety, theCosmic Crisp. Even in New York, which has traditionally favoured the McIntosh, production has fallen from about a quarter of the state's total volume in the 1980s to about 14 percent in the 2020s.[28] The decline of older varieties like the McIntosh and Red Delicious follows the advent of newer varieties like the Honeycrisp, offering consumers sweeter and more complex tastes. They also risk becoming mere commodities—that is, common and cheap products—making it them less profitable for farmers and distributors.[28]

The McIntosh has been designated the national apple of Canada.[31] A popular subscription funded a plaque placed 100 metres (110 yd) from the original McIntosh tree in 1912. TheOntario Archaeological and Historic Sites Board replaced the plaque with a more descriptive one in 1962, and theHistoric Sites and Monuments Board of Canada put up another in a park nearby in 2001, by a painted mural commemorating the fruit.[1]
Apple Inc. employeeJef Raskin named theMacintosh line of personal computers after the McIntosh.[19] He deliberately misspelled the name to avoid conflict with the hi-fi equipment manufacturerMcIntosh Laboratory. Apple's attempt in 1982 to trademark the name Macintosh was nevertheless denied due to the phonetic similarity between Apple's product and the name of the hi-fi manufacturer. Apple licensed the rights to the name in 1983, and bought the trademark in 1986.[32]
In 1995, theRoyal Canadian Mint commissioned Toronto artist Roger Hill to design a commemorativesilver dollar for release in 1996. Mint engraver Sheldon Beveridge engraved the image of a group of three McIntoshes and a McIntosh blossom, which adorn one side with a ribbon naming the variety. An inscription on the edge reads "1796 Canada Dollar 1996". Issued sheathed in a silver cardboard sleeve in a black leatherette case, 133,779 pieces of the proof were sold, as well as 58,834 pieces of the uncirculated version in a plastic capsule and silver sleeve.[1]
