As a Fellow in the Harvard Leadership Initiative, MacGregor worked as a part of Harvard Business School with a distinguished group of scholars to raise the level of leadership in millions of people. Prior to his Harvard Fellowship, MacGregor helped build the desktop and notebook business for Austin-based Dell Computer Corporation in the 1990s. As the vice president and general manager of five different divisions of the company from 1993-99, he was successful in doubling the revenue of several of his divisions after only one year under his direction. While at Dell, MacGregor spent two years as a member of the 15-member Executive Committee that managed the company’s operations.

In 1992, MacGregor joined Data General Corporation as their vice president of hardware. In his effort to make Data General a more efficient organization, MacGregor re-engineered the company’s development operation by incorporating a coherent product strategy and product planning process.

Before joining Data General, MacGregor founded Solbourne Computer Incorporated. Serving as the president and CEO, he started the Japanese-based company in a partnership with Matsushita Electric Industrial Co. Solbourne relocated to the United States in Colorado and started the clone market for UNIX workstations in America. MacGregor used a management strategy that combined the best of an American company with the strength of a major Japanese corporation to create a new market.

MacGregor pursued his doctorate in Information Science at Kyoto University in Japan after completing a five-year term as a microprocessor designer at Austin-based Motorola, Inc. He completed his master’s degree in computer science at the University Illinois in 1980 after obtaining his Bachelor of Arts in history from the University of Maryland.

MacGregor has also established The MacGregor Foundation, a non-profit organization committed to support 12-step based drug and alcohol recovery in the Austin community. In 1999, MacGregor endowed the Muroga-Faiman Professorship at the University of Illinois and has been a member of the United Way Alexis de Tocqueville Society. MacGregor serves on the Board of Capital Area United Way and is President of the Board for Austin Recovery, the only agency in the central Texas area to provide drug and alcohol treatment for the working poor.
