Maclennan's academic career included lecturing at Wits University and the University of Cape Town.[2] He taught in both South Africa and the United States.[3] He began teaching at Rhodes University in 1966, teaching English there for more than 40 years,[2] although he officially retired in 1994. In later years, he continued to teach at the university, giving weekly seminars for another decade.[4]
In his final years, he self-published a number of works of poetry.[4] In his last decade, Maclennan had motor-neuron disease. He suffered a stroke in January 2009, although his mind was not affected by it. He died on 9 February 2009, in Port Elizabeth.[2]
