Então eu tentei instalar o Windows 10 usando o BootCamp, mas de alguma forma o instalador do Windows não permitiu que eu escolhesse a partição, tentei formatar um novo dentro do instalador, mas ainda sem bloqueio ...
então decidi cancelar a instalação, tudo correu bem, mas o aplicativo de mensagem me deu este erro:
Messages cannot be opened because of a problem.
Check with the developer to make sure Messaes works with this version o OS X. You may need to reinstall the application...
Como reinstalar isso?
