Development

In the press release for ''Doctors'' in March 2000, Timothy was said to be "thrilled" to be on the show, adding: "On set, there's an amazing sense of drama and commitment from everyone around. People want it to be a success".
Described as an "old-fashioned and highly-respected physician who isn't afraid to speak his mind", Timothy added that Brendan (known to his colleagues as Mac) is "

grown older."
In an interview with ''Sussex Life'', Timothy stated of his time on ''Doctors'' that he loved "the dramatic standards achieved by the fast-paced series, despite the kind of squeeze on time and resources unheard of," adding, "The budget was a joke and the pressure more intense than anything I’d ever experienced. But it was six years of great fun, and I got to direct, which I loved".
When asked if he had picked up any medical knowledge from the role, he said, "No, not really. I spent a week with a real vet in Yorkshire and a day with a real GP during his surgery, but I didn't watch procedures. The actual procedures – how to take blood pressure and that sort of thing – I picked up as I went along".

if Mac might return, to which he replied: "I don't know why we'd do that unless there were a very good reason. The show has moved on since hristopher Timothywas with us, so I don't think anyone would want the character back just out of nostalgia. But if it's motivated, impacts our characters, and makes sense dramatically, then never say never".

( Maggie Cronin), with whom he has one son, Ciaran, whose traumatic birth leads to Mac becoming an alcoholic. This marriage lasts just over 10 years when Kate has an affair with a priest, Father David Quinn ( Richard Standing). Kate leaves Mac, taking Ciaran with her, which results in Mac having a heart attack. The near-death experience leads to ex-wife Julia coming back into his life, and the two resume their relationship. Mac then remarries Julia. In December 2003, Ciaran is kidnapped by George and Ronnie’s neighbour, who has recently lost her son, while Ciaran is in the care of Julia. Mac blames Julia and, even after Ciaran’s safe return, their relationship is strained. A few months later, Kate falls in love with Mike, a locum at Best Practice, and she moves to Ireland with him and Ciaran, devastating Mac. Julia and Mac’s marriage comes under strain again when Julia’s former flame, Harry Fisher, begins work at Best Practice, and Mac becomes jealous. This jealousy leads to their temporary split, and Julia almost agreeing to set up a Super Pratice with Harry, to be in direct competition with Mac. Eventually, she sees Harry’s true colours and reunites with Mac. Further trouble arises when Julia is suspected of setting fire to the practice to claim on the insurance, but she is later acquitted when the real suspect (Jack’s ex-wife Ria) is revealed. Mac and Julia take in Julia’s friend Marcia, an alcoholic, and try and help her fight her addiction. During her stay, Marcia reveals Julia is repaying her for when she supported Julia during a difficult time: when she aborted Mac’s baby after their first marriage ended. This causes even more cracks in their marriage, and they split, again. They eventually reunite again, although Mac never truly forgives Julia.
Mac becomes friends with Peter Kendrick ( Robert Cavanah)through a mentor scheme. Peter is under considerable stress, working in a poorly funded and understaffed doctor’s practice, so Mac intervenes and tries to get him support. This fails, and, despite weeks of Mac’s support, Peter takes his own life. Mac finds him, and is haunted by his death.
Early in the eighth series (2006), Mac begins an affair with his ex-wife Kate when he visits her in Ireland off-screen. The affair is secret for a while, with the two having secret meetings in hotels for weekends away, under the guise of golfing weekends and conferences. However, when Kate and Ciaran visit Letherbridge, Mac and Kate are caught kissing in Mac’s office, by the Mill’s new receptionist Donna. Donna assures Mac she will not reveal the affair. However, a few weeks later, Mac attends a conference in The Cotswolds, with Kate. Julia, still unaware of the affair, drives down to The Cotswolds to surprise Mac, only to find Mac and Kate kissing. When Mac returns home, he begs Julia to forgive him, but she refuses. She orders him to move out and leave The Mill. At first, Mac refuses, but after speaking with Donna, announces his resignation to a shocked Faith, George, Greg, Jimmi, Nick and Donna. Kate arrives in a taxi, and leaves with Mac, with a devastated Julia watching from her office window. They divorce the following year.
Mac arrives at the Mill Health Centre 18 years after his exit, confused about why he cannot find physical patient records. Despite retiring years prior, Mac has dementia and believes he is still a doctor. He finds himself in people's offices and treating patients, with staff and patients unaware that he is suffering from memory loss. Jimmi, the only remaining staff member from Mac's time at the Mill, recognises him and contacts Ciaran, who collects Mac and assists him back to Dublin.
