En primer lugar, he buscado durante todo un día y aunque hay similar problemas alrededor, no puedo encontrar a nadie que tenga este problema exacto.
Mi hackintosh corriendo 10.12.3 tiene OpenSSH instalado vía homebrew. Se cuelga en la misma línea "rekey" sin importar a qué servidor me esté conectando, y no tengo idea de por qué.
(nota: el resultado esperado de lo siguiente debería terminar con
Permiso denegado (clave pública).
porque no he instalado el cert, en su lugar sólo estoy usando git@github.com para probar. Pero ni siquiera llega hasta ahí, y ese es el problema. Mi servidor casero con ubuntu produce el mismo punto de cuelgue).

Otros ordenadores (por ejemplo el Macbook Air) con el ssh nativo de mac no tienen ningún problema. Es sólo el hackintosh. ¿Alguna idea de dónde puedo solucionar el problema a continuación?
Gracias de antemano.
Nota: Puedo hacer ssh al hackintosh sin problemas, pero no desde él.

Ssh no encuentra un fichero_clave válido (comprueba las líneas 7-22: todas muestran la respuesta tipo -1). ¿Has probado con el
