Estou tentando rodar o seguinte comando no meu mac:
nu.authenticate_with_cert(...)
Mas esta retornando o seguinte erro:

O erro parece relacionado ao pyOpenSSL, mas testei todas as sugestões de lá e ainda não funciona.

Puts, não sei muito como ajudar.
Acho que tenho o mesmo mac que você e não tenho problemas.
Você poderia tentar rodar o seu código dentro de um container docker pra ver o que acontece?
algo como
# Assumindo que na pasta atual tenha uma pasta `key` com o seu certificado
$ docker run --rm -it -v $(pwd)/key:/key python:3.9 bash
$ pip install pynubank
$ python
> from pynubank import Nubank
> nu = Nubank()
> nu.authenticate_with_cert('CPF', 'SENHA', '/key/cert.p12')WittmannF commented
Via docker funcionou @andreroggeri ! Agradeço por compartilhar rapidamente os passos. Quanto ao problema com pyopenssl, é um issue aberto há 3 anos, portanto não parece trivial. Mas achei curioso que no seu Mac está funcionando. O meu é Pro 2021 M1 rodando MacOS Monterey. Para ambiente em python utilizo conda miniforge.

Opa, para atualizar, consegui resolver instalando cffi via pip:
pip install cffi
A versão em conda ainda não possui o patch que resolve a questão do pyOpenSSL
