I'm installing SEP 1.43RU1 on any Mac in Altiris that is running Catalina or Big Sur. I don't want it installed on any other OS version so I use Applicabilty rules. Catalina is easy to specify using 10.15 however I cannot get Big Sur to work. I've tried 11.x or 11 blank or 11.1, 11..2, 11.3, 11.4 and so on but nothing seems to work. Does anyone have an applicability rule setup for Big Sur that is working? Thanks!
