I am getting "Unknown Error = -2,147,414,007" on creating a certificate through the Keychain app.
Steps to Recreate:
Open the Keychain Access application. Select Certificate Assistant > Create a Certificate in the application menu (Keychain Access). Only Modified Parameters are listed. The remaining options are kept with default values.
Name of Certificate = gdbcert
Identity Type = Self Signed Root
Certificate Type = Code Signing
Check the Let me override defaults checkbox, and click Continue.
- On the next page, leave Security Number to be 1, and set Validity Period to 3650.
- Then click Continue once again, and keep doing so to skip the next six screens until you see the one entitled Specify a Location For The Certificate.
- For the only property, Keychain, choose System from the drop-down list. Lastly, click Create, type in your password, if prompted, and click Done.
Update: I'm able to create certificates to the Login Keychain. The issue is only when I try to create certificates for the System Keychain.
