Hello, I'm attempting to save my developer's certificate in .p12 format through Keychain Access so I may share it with another computer. For some reason, however, when I attempt to export it as .p12, the option to do so is not highlighted, unlike .cer, .pem, and .p7b. Why is .p12 the only one that is not highlighted? Can't figure this out and need to send the certificate to my senior developer. Anyone able to provide any leads? Thanks very much in advance.
