Eu usei esses comandos no Terminal,

<code>    1.V******-Ms-iMac-2:~ c*****$ openssl pkcs12 -in apns-dev-cert.p12 -out apns-dev-cert.pem -nodes -clcerts
        Response : Error opening input file apns-dev-cert.p12
        Certificates.p12: No such file or directory
    2.V******-Ms-iMac-2:~ c*****$ openssl pkcs12 -clcerts -nokeys -out apns-dev-cert.pem -in apns-dev-cert.p12
        Response : Error opening input file apns-dev-cert.p12

   5.V******-Ms-iMac-2:~ c*****$ cd/Users/c*****/Desktop/A
-bash: cd/Users/c*****/Desktop/A: No such file or directory
</code>

Eu não consigo entender por que o terminal sempre dizendo "Nenhum tal arquivo ou diretório"? Onde eu preciso salvar o arquivo .p12 no meu Mac?

DivertidoTerminal app Version 2.1.2 (273.1). Mac OS X version 10.6.8.

Você pode por favor o que eu preciso fazer? Eu preciso ativar o APNS usando o arquivo .pem. Por favor me ajude. Desde já, obrigado.

EDITAR:

Eu adicionei tentado Raywenderlich.com termial código no meu aplicativo mac Terminal

<code>1. V******-Ms-iMac-2:~ c*****$ pwd
/Users/creagx
2. V******-Ms-iMac-2:~ c*****$ cd/ Users/creagx/Desktop/A
-bash: cd/: No such file or directory
