Using your YubiKey as a smart card in macOS

[rube-de]

At the installation page of the ykman it says

Yubico strongly recommends that those who want to use a GUI for configuring individual YubiKeys choose Yubico Authenticator instead of the YubiKey Manager GUI. The Authenticator is newer and has much more functionality.

still for setting it up for macOS this isn't true.

Is there any plans to finally bring all functionality of the the ykman to the Authenticator?

While there is no "Set up for MacOS" button in the app, the same functionality is there already:

Generate new certificates in the Authentication (9a), and Key Management (9d) slots in the Certificates view will have the same effect.

You will need to enter a Subject for each one, and while this shouldn't matter for MacOS if you want them to match what YubiKey Manager GUI does you can use: "CN=Yubico PIV Authentication" and "CN=Yubico PIV Encryption" respectively. All other settings can be left at their defaults.

EDIT: The YubiKey Manager GUI also sets the expiration dates to 30 years in the future, while the default is 1 year. You can change the date when generating the certificates to a suitable value.
