OpenSim Mac M1

[Mazen Al Borno]

Hi all,

Tried installing OpenSim on my M1 mac using the conda environment, Here are the exact steps I took:

-Opened a terminal on x86_64.
-sudo conda create -n opensimEnv python=3.9
-conda activate opensimEnv
-sudo conda install -c opensim-org opensim

After opening python and importing opensim, I get this error:
ImportError: dlopen(..._simbody.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e'))

Please let me know if you have ideas on how to fix this. Thanks.

I just tried this again on Mac. Just in case it helps someone else: It worked for me when I made sure that the python version that I used (3.11) was the same as the one that downloaded the files with conda.
