Code Signing

[Paul Dupuis]

To code sign a macOS app, I think you need an Apple issues developer 
certificate.

Apple Developer membership is something like $99 USD per year (or around 
that). You can sign up if you don;t already have an account at 
developer.apple.com. A code signing cert is then "free" for anyone with 
a developer account.

I downloaded Xcode, and also Trevor DeVore’s code signing app. I chose the app I want to sign, but now it’s asking me the name of the certificiate. I know I have a code signing certificate because when I digitally sign PDFs, that’s the certificate I have. I found it in my Keychain, and made sure it was valid for code signing. They only problem is it is a self signed certificate.
