[1] A pupil at Barrhead High School, where she achieved five Highers in 2022,[2] Maclean progressed through the girls' academy at Rangers (although she is a supporter of St Mirren[3] where the women's section of the club play at a low level having only been established in 2018).
She made her senior debut during the 2021–22 Scottish Women's Premier League season aged 16, making a handful of appearances as Rangers won their first championship.
[5][6] After establishing herself as a regular in the squad during the 2022–23 season, in which she also made four appearances (three starts) in the UEFA Women's Champions League, was introduced as a late substitute in Rangers' win over Hibernian in the SWPL Cup final and was nominated for the PFA Scotland Women's Young Player of the Year, Maclean signed an extended contract in May 2023.
[9] Rangers won the 2023–24 Scottish Women's Premier League Cup[10] and the 2023–24 Scottish Women's Cup[11] (Maclean missed the first final due to injury and started in the second) although they missed out on the SWPL championship again, this time on goal difference.
[14] As a midfielder with a low centre of gravity, good ball control and passing skills, her style of play has been compared to that of Andres Iniesta[15] and Erin Cuthbert.
