For anyone having the problem where after imaging a computer the only profile it is picking up is the main MDM profile then this might help you. We repair our macbooks in house so the problem we had was with logic boards that were replaced but the serial number was never put back on the board. This caused no serial number to show up in the mdm for the laptops. Because of that it caused some problem with pulling down profiles. Boot the laptop up to the AST Server and enter in the serial number and you should be good to go. Hopefully this saves some time for someone.
