I have an original license from new and S4 mk1 Controller on 2012 MBP El Capitan 10.11.6 - it still works well but due to its age i have been steadily replacing parts on the MBP - as i had to replace the keyboard i stupidly thought i'd replace the motherboard at the same time (its pretty much had everything else changed apart from the unibody case ) now am trying to reactivate my software but cant get Native Access to install (tried the closest few legacy installers ) all have same error - "No Compatible Update Found" - have signed out of iCloud and cleared cache etc etc problem remains - is there a way i can get native Access to run on this old machine? Is there a min requirement for OS that Pro2 and S4 mk1 will both be compatible with? - im going to try putting the old motherboard back in case this might work for now but if it doesnt i really do need to figure out how to get Pro2 and S4 working again - please help
