Hello, Yubikey Manager for macOS (slug:

yubico-yubikey-manager/darwin

) has been deprecated since February 2025. It has finally been removed from homebrew which means we can no longer support it in our FMA catalog. Releasing FMA updates for all other apps are blocked until this is removed, so we plan to take action on this today. If you've got Fleet deployed via GitOps, you'll need to remove this from your yaml. You can try to use the old installer URL as a custom package (but we are unsure how long that will work). Please let us know if you have any questions!
