I've not installed the beta of macos Sierra, but I do have some questions on the new Gatekeeper function. I'm hoping those who have more knowledge on this can chime in. From the keynote, it seems that Apple tightened up Gatekeper, and in some cases not allowing a given app to run. How will this prevent apps downloaded from outside of the MAS running? What circumstances will cause it to prevent those apps from running? Can I disable it, or at least lower its level of control (like have it behave under 10.11). Thoughts on the new Gatekeeper - is a good thing what apple did? To intrusive? or on the opposite side of things, not enough?
