No matching signing identity found "Mac Developer:"

Question

I am building a project downloaded from github. this project targets iphone/ipad/mac.When i build this project, it says

No matching signing identity found 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.

When i click fix issue button it says The selected team doesn't have a Mac Developer Program membership Select a team with a Mac Developer Program membership and try again. 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?

Any help would be much appreciated.

screenshot of General settings in this project is as follows:

Answer 1

Self-Signed Codesign Certificate

It's really simple to fix this; you can create your own self-signed codesign certificate in Keychain Access. If you decide to distribute your app later, or want it to behave nicely with Gatekeeper then you'll of course need to join the Mac Developer Program.

*If it's primarily for your own usage though then you can likely choose not to codesign it at all.
