vlad12 - thanks for the feedback. Yes, that is the common solution for this error, but not for the case when the name matches but with two certs (work and personal, for example, as in my case). In this case the name does match, but there are two certs that match the same (correct) name, and Xcode can't determine which to use when attempting to sign (also showing the error in organizer) unless one of them (either one) is removed from the system. If anyone has solutions for this specific scenario, I would love to hear it.

Thanks.
