The App for MAC Students under the direction of SAC. This application will keep all students up to date. There are pages dedicated to updates regarding school events and athletics. A teacher directory and links to Mackenzie's social networks can be found in the app. In addition, the calendar has all important upcoming events so it's easy to see what's next at MAC. Note 1: When calling for absences, press "1" after being connected. Your parent or guardian must call the school to inform them of your absences. The same applies when calling teachers about missing a test during that absence. A written note to the teacher must still be provided the following day.
