Macos Catalina 10.15 4 Update Download
Invalid private key and certificate pairing
If you receive an error message saying, 'Xcode could not find a valid private-key/certificate pair for this profile in your keychain,” the Keychain Access application on your Mac is missing either the public or private key for the certificate you’re using to sign your app.
This often happens when you're trying to sign and build your app from a different Mac than the one you originally used to request your code signing certificate. It can also happen if your certificate has expired or has been revoked. Ensure that your app’s provisioning profile contains a valid code signing certificate, and that the Keychain Access application on your Mac contains that certificate, the private key originally used to generate that certificate, and the WWDR Intermediate Certificate.

For instructions on how to resolve this and other code signing errors, review the Code Signing Support page.
