title: No matching signing identity found "Mac Developer:"
body: <p>I am building a project downloaded from github. this project targets iphone/ipad/mac.When i build this project, it says </p>
  
  <p><strong>No matching signing identity found</strong> 
  <code>No signing identities (i.e. certificate and private key pair) matching the value specified in your build settings, "Mac Developer:", were found. Xcode can update your build settings to their recommended values.</code></p>
  
  <p>When i click fix issue button it says <strong>The selected team doesn't have a Mac Developer Program membership</strong> <code>Select a team with a Mac Developer Program membership and try again</code>. I only have an iOS developer program membership, no mac membership. I've change the Code Signing Identity in Build Settings Tab, but the issue still exist. Can i build the project? How can i fix this issue?</p>
  
  <p>Any help would be much appreciated. </p>
