After a year managing the Bully Wee, he was appointed as assistant to Scot Symon at Rangers in 1967. Symon resigned just five weeks later and White was appointed manager on 1 November. His reign was generally unsuccessful and he was the only Rangers manager not to win any major honours until Paul Le Guen (July 2006-Jan 2007). With Rangers' high expectations and the success at Celtic under Jock Stein, the pressure built on White and after a Cup Winners Cup exit to Polish team Górnik Zabrze in 1969 he was sacked as manager. He was the first Rangers manager never to win a trophy.
He later went on to manage Dundee and guided them to a Scottish League Cup triumph in 1973-74. Somewhat ironically the victory in the cup final came against Celtic, the team who had caused him so many problems at Rangers. His success didn't last however, and Dundee were relegated at the end of the inaugural Scottish Premier Division season in 1976. White lasted one more year before retiring after failing to get the side promoted.
