How To Import A Certificate Into Mac OS

Depending on the circumstance you may need to import an SSL or Code Signing Certificate into a Mac system.

Typically all Mac OS systems refer to the Mac’s Keychain Access for all things pertaining to digital certificates, unless by a different design on whatever application the you are using.

Mac Systems use pfx/p12 files that contain both the public & private key to perform its signing, encryption, etc.. similar to Microsoft.  Therefore, if you need to import a functional SSL or Code Signing certificate into Mac you will need a .pfx/.p12

To import your SSL or Code Signing Certificate into you Mac system perform the following.

Importing your  PKCS#12 .pfx/.P12 file on Mac OS X

1. To open Keychain Access, start by clicking on Go in the Finder menu and the select Utilities.
2. When the Utilities window opens up, look for and click on the icon named Keychain Access.
   Note: Alternatively, you can open the Keychain Access by typing “Keychain Access” in the Spotlight search field at the top.
3. Within the Keychain Access menu select File > click Import Items.
   
4. Browse to the .p12 or .pfx file that you want to import and open it.
