Has anyone else encountered a change in the find my mac no longer being present in nvram with 15.x (esp 15.6) ?

Hey David! We addressed this recently with a custom launcher table to call the Find My framework. Not sure if you are using launcher still these days but if you are you should be able to query it using

kolide_find_my

thanks @fritz that's great to here it's at least feasible to resolve; not presently using launcher at this moment in time however I did find the OSS'ed code here and will review and see if I can come up with an interim fix based on this; thank you once again to you and the team!
