how I got FlatCAM 8.1 working on OS X [a long time ago — see comment thread for lots of good tips from others!]

install_flatcam.sh

brew update
brew install pyqt geos spatialindex
easy_install pip
pip install virtualenv

cd Development/Others\'/
mkdir FlatCAM
cd FlatCAM
virtualenv env
source env/bin/activate
pip install numpy matplotlib rtree scipy shapely simplejson
# copy contents of FlatCAM_8.1.zip into FlatCAM folder
python FlatCAM.py

anyone know about this error ?

Traceback (most recent call last):

^^^^^^^^^^^^^^^^^^
AttributeError: 'FileFinder' object has no attribute 'find_module'

I presume you are trying to run flatcam with python 3.12, because FileFinder.find_module, which has been deprecated since python 3.4 and removed in 3.12 (see https://docs.python.org/3.11/library/importlib.html#importlib.abc.PathEntryFinder.find_module).

So you can either switch to python < 3.12 or try to fix that line by using load_spec instead.
