title: export public key from keychain access
body: <p>I want to archive my app for distribution on two computers. I exported the private key successfully and imported it to my second machine, however run into errors when imported the public key. </p>
  
  <p>Everywhere I search people always mention only exporting of the private key - why is that? how can I export the public key and transfer it successfully? what am I doing wrong? </p>
