A new and distinct apricot variety is described. The variety results from selection among a population of seedlings derived from controlled crossing of the varieties ‘Bhart’ (not patented), marketed as Orangered™, and an unreleased selection (not patented) which was the result of crossing ‘Cluthagold’ (not patented) and ‘Late Moorpark’ (not patented). The new variety is distinguished from others by the deep rose over color of the mature fruit accompanied by deep orange colored firm flesh with high soluble solids content. Fruit of ‘Mac12/45’ matures in early February in Otago, New Zealand and is notably precocious, fruiting in the second year after planting in Otago, New Zealand.
