(DC) [Import] Digital Certificate (macOS)

Before installing your digital certificate on your Apple iOS device, please consult with the ISO page

and ensure your device has been secured. After installing a your digital certificate on your device, anyone with physical access to your device will have the ability to decrypt and view sensitive information within email or other applications on the device. PLEASE ENSURE that you have protected/hardened as it very important to keep sensitive information away from prying eyes.

macOS utilizes a tool called the Keychain Access, that globally manages certificates for the entire operating systems and applications that utilize this feature (AppleMail, Outlook, etc..). This means that you can import the certificate once, and have it recognized and utilized without any special configuration.

NOT ALL applications utilize the Keychain Access, please make sure you have access to third-party application documentation to assist you using your digital client certificate with that application.
