Environment:

Unity Version: Unity 2021.2.8f1 OS + version: Mac 11.3.1 ML-Agents version: ml-agents-release_18 Environment: Anaconda virtual environment, installed all necessary package -python version: 3.8.6

Note:

This issue appeared similar here and the person was able to solve the issue with the Mac specific configurations for the bundle file. I don't see the alert so I cannot just follow his advice.

Hi @yachty66, are you on an M1 mac by any chance?

I build with the following environment and everything worked fine now:

macOS Big Sur 11.3.1 Unity Editor = 2020.3.15f2 Unity-Hub = 3.0.1 Python = 3.8 ML-Agents Release 19
