When I upgraded from an Intel to Apple Silicon MacBook Pro, I couldn’t get Starry Night Enthusiast 8 by Simulation Curriculum to work. The error message indicated that the application was damaged, even after a fresh installation.

As a last resort, I deleted this folder:

Users > [username] > Library > Application Support > Simulation Curriculum

When I ran the application again, instead of reporting an error, it prompted for software licensing credentials. After entering my information, the application launched without a hitch. Just in time for C/2023 A3 (Tsuchinshan–ATLAS).
