On my Mac, I have installed the required certificates and keys to develop and distribute my own personally developed iOS Apps via my own iOS Developers' License. However, my client would like me to use his License to distribute (Ad-Hoc) betas and eventually distribute the app to the app store.
Please can you tell me how I can install his developer license on my Mac without affecting my personal developer certificates and keys already installed on my Mac?
Furthermore, is this even possible?
Edit---
Sorry, I didn't mention; I don't want to have to revoke my client's pre-existing certificates on his developer account.
