Running El Capitan. I have a spare partition where I test major MAS OS upgrades prior applying them on my production environment. I will update to Sierra and higher up see if that helps but doubt it.
SIP is not disabled but to my understanding there is no need for CAT for that card so not sure why disable SIP. I might be wrong.
There are lots of small variation for these cards. If you can't make it work straight away, better disable SIP and run CAT.
