We currently anticipate completing integration and testing of our data reduction software with AstroConda in November this year. In the meantime, our recommended platform is still Ureka 1.5.1 or 1.5.2.

For any users with a pressing need to try running our software on MacOS 10.12 now, an updated Ureka install script is provided below (replacing the one found on the Ureka Web page), which will recognize the new OS:
