Eu tenho alguns iMacs com SSDs duplos, então eles são ambos Ubuntu 16.04 LTS e MacOSX. O problema, que é bem conhecido, é que há um bug no patch de segurança do MacOSX que desativou a placa BCM57765. Eu havia seguido todas as etapas sugeridas no MacOS X, mas ainda assim a placa NÃO está habilitada. Pior que isso é que não posso mais ativar o cartão no Ubuntu. Como o Ubuntu é meu sistema operacional principal nessas máquinas, eu apenas me preocupo com a placa ethernet para trabalhar com o Ubuntu. Eu só posso fazer o wi-fi funcionar nesta máquina agora.
Tenho certeza de que muitos usuários do Ubuntu estão enfrentando os mesmos problemas com o hardware do iMac, de acordo com uma pesquisa que fiz.
Tenho algumas postagens aqui no link
Espero que alguns de vocês possam dar algumas dicas sobre como ativar essa placa novamente. Estava trabalhando antes. Eu tinha o cabo verificado, switch, etc. Ele funciona com outra máquina muito bem. São as atualizações ruins do MacOS X que desativaram essa placa. Também executei diagnósticos e não há absolutamente nenhum problema com esse cartão.
Obrigado antecipadamente!
Aqui estão alguns resultados desta máquina:
