Machan was born in Hungary. Machan's father hired a smuggler to get him out of Hungary when he was 14 years of age and he came to the United States three years later. By 1965, Machan graduated Claremont McKenna College (then Claremont Men's College). He took his Masters of Arts in Philosophy at New York University from 1965 to 1966, and his Ph.D in Philosophy at University of California-Santa Barbara, 1966-1971.

He was a visiting professor at the United States Military Academy (West Point) in 1992—1993 and has taught at universities in California, New York, Switzerland, and Alabama. Machan edited Reason for two years and was the editor of Reason Papers, an annual journal of interdisciplinary normative studies, for 25 years. He lectures in Europe, South Africa, New Zealand, Budapest, Hungary, Prague, Czech Republic the Republic of Georgia, Armenia and Latin America on business ethics and political philosophy. Professor Machan lives in Silverado Canyon, Orange County, California. (As a trivial curiosity, Machan is known to have a penchant for the color orange, and frequently incorporates the color into his daily apparel, often by way of an orange ring, orange socks or orange shoelaces.)

He was previously married to Marilynn H. Walther, as well as to Marty Zupan and to Jamie Andersen with whom he had daughters Kate and Erin, respectively. He also adopted Thomas, Jamie's son from a previous marriage.

Machan has written a memoir, The Man Without a Hobby: Adventures of a Gregarious Egoist (Hamilton Books, 2004).

Machan's work usually focuses on political philosophy, specifically natural rights theory. See his Individuals and Their Rights [Open Court, 1989] and also a more recent work, Libertarianism Defended [Ashgate, 2006]. He also writes frequently on business ethics, a field in which he deploys a neo-Aristotelian ethical stance whereby commercial and business conduct gain their moral standing by constituting extensions of the virtues of productivity and prudence. He also argues that the field presupposes the institution of the right to private property (one cannot trade what one does not own or hasn't been authorized to trade by the owner). (See The Business of Commerce, Examining an Honorable Profession, and A Primer on Business Ethics, both with James Chesher and The Morality of Business, A Profession of Human Wealth Care [Springer, 2007].)]Machan also writes in the field of epistemology. His main focus has been to challenge the conception of human knowledge whereby to know that P amounts to having reached a final, perfect, timeless, and finished understanding of P. Instead Machan draws on Ayn Rand's contextual conception of human knowledge (from Rand's Introduction to Objectivist Epistemology) and the insights of J. L. Austin, from his paper "Other Minds", and Gilbert Harman, from his book Thought. (See Machan's book Objectivity [Ashgate, 2004].) Machan has also argued against animal rights (in his widely reprinted paper "Do Animals Have Rights?" [1991] and his book Putting Humans First: Why We Are Nature's Favorite [2004]). His full ethical position is developed in his book Classical Individualism: The Supreme Importance of Each Human Being (Routledge, 1998) and it is applied in, among other books, Generosity: Virtue in Civil Society (Cato Institute, 1998).

Machan has also worked on the problem of free will he has defended a secular, naturalist (but not materialist) notion of human initiative (see his books The Pseudo-Science of B. F. Skinner [1974; 2007] and Initiative: Human Agency and Society [2000]) and the ethics of animal treatment (see his book Putting Humans First [2004]). He is also global warming skeptic.
