Hi there,
It seems that the currently-provided conda environment file (here) does not build on OSX:
UnsatisfiableError: The following specifications were found to be incompatible with each other:

Package wheel conflicts for:
python=3.8 -> pip -> wheel
pip -> wheel
- Changing to python=3.10 allows the environment to resolve, but fails in
pip install pyo. - Disabling the
pyoinstall completes the conda environment setup, but I have not tested what PsychoPy functionality will be broken due to this. - Using rosetta / arch i386 instead of ARM (I’m on an M1 mac) works with python=3.10, and installs
pyo, but fails underpython=3.8.
In general I would like to request an update of the conda environment file linked from the official installation page that might work more robustly across different systems, by someone who has a better idea of compatibilities and the current recommended Python version in PsychoPy than I do.
