На маке стоит: OpenSSH 6.9_p1, LibreSSL 2.1.8
На воркстейшоне: OpenSSH 7.2_p2, OpenSSL 1.0.2h
Всё работает, с мака на воркстейшон и обратно можно ходить по паролю и без, по ключам.
Но если на воркстейшоне обновить OpenSSH до 7.3_p1, то на идентичных с 7.2_p2 конфигах с мака на воркстейшон уже не зайти:
