[Qgis-user] QGIS 4 Mac - Install additional python packages

Hi QGIS User List,

I am developing a python based QGIS processing script which is working great on a Windows installation.  However, when I try to run it on my Mac I get an error stating the Matplotlib package is not installed in the python environment.

How can I install additional packages into the QGIS python environment?  I have found a few old StackOverflow threads mentioning installing via Pip3 from within the QGIS Application Package.  However, Pip3 doesn't seem to be contained there any more.

Any thoughts? Thanks,
