He was senior vice president of software engineering at Apple from 1997 to 2003, and then chief software technology officer from 2003 to 2006. There, he rearchitected NeXTstep to become macOS, which became iOS. He was a longtime friend of Steve Jobs.

Theranos and Dolby Labs
Tevanian left Apple on March 31, 2006, and joined the board of Dolby Labs and Theranos, Inc. He resigned from the board of Theranos in late 2007, with an acrimonious ending as he faced legal threats and was forced to sign a waiver to waive his right to buy a company cofounder's shares. In May 2006, he joined the board of Tellme Networks, which was later sold to Microsoft. On January 12, 2010, he became managing director of Elevation Partners. In July 2015 he cofounded NextEquity Partners and is currently serving as Managing Director.
