Jeff Johnson:

At their recent Worldwide Developers Conference, Apple announced macOS 10.12 (Sierra), the next major version of the Mac operating system. Sierra is scheduled for official release in the fall, and we’re hard at work on getting our software ready for it. For now, however, we recommend that if you can’t live without our software — which we love to hear! — you should stick with 10.11 (El Capitan) or lower. We’ll be releasing fully compatible updates for 10.12 as soon as possible. For more detailed information, please see our Status page.

I’d like to take a few minutes now to talk directly to fellow software developers about Sierra, specifically about a new Sierra security feature called “Gatekeeper Path Randomization” (GPR) that has serious implications for software delivered outside of the Mac App Store.
