Answer 2

Hope it may help you In Keychain, select three items: Your private key, public key and the cert from Apple

CMD+Click to select "export 3 items"

and you will export one .cer file. Then double click to import the file without keying any password to protect so.

or you should import cert first and then import both public and private key. Make sure you also have the Apple Developer Relations Root CA certificate in your keychain. That is what is used to verify the certificate. See in your keychain access whether it has been paired correctly.
