Byobu no funciona en la nueva instalación de OSX

Estoy tratando de migrar de linux a osx, pero aparentemente byobu no funciona out-of-the-box en mi máquina. Las teclas Fn funcionan parcialmente. Puedo ver el mensaje de error "no hay ventanas anteriores" y "no hay ventanas siguientes" cuando presiono F3 y F4, pero presionando F2 no logra crear una nueva ventana en la terminal de byobu.

No encuentro el atajo correcto para dividir el terminal. Estoy tratando de reconfigurar byobu para especificar mi secuencia de escape. Desafortunadamente, no puedo deshacerme del siguiente error:

(base)   ~ byobu-config 
ERROR: Could not import the python snack module

A mí me parece que el módulo snack es antiguo, ya que los errores que veo están relacionados con que las funciones de impresión no tienen paréntesis (que se hicieron obligatorios en python3).

(base)   ~ which python3
/opt/homebrew/bin/python3

(base)   ~ python3 -m pip install snack

¿Tienes alguna idea de cómo hacer que byobu funcione en osx?

Gracias.
