"failed to execute PosixPath('dot'), make sure the Graphviz executables are on your systems" PATH on mac in sage math

I want to use graphviz for graph vizualisation. I would like to use source from graphviz:

def display(self, verbose=False):
        '''
        Prints the QMDD as a dot graph.
        '''
        filename = '.tmp.dot'
        self.save_as_dot(filename, verbose)
        s = Source.from_file(filename)
        s.view()
        os.remove(filename)
        # Can't manage to properly remove file .tmp.dot.pdf

I always experience this error message : ""failed to execute PosixPath('dot'), make sure the Graphviz executables are on your systems' PATH.""

I'm using a mac and a sage math in a jupyter notebook. I've already tried to do pip3 install graphviz and brew install graphviz. Furthermore I had the path : "/Library/SageMath/local/lib/python3.9/site-packages/graphviz" to the system path but each solutions didn't work.
