Yubico Forum

Hey all,

today I installed the YubiKey PIV Manager (1.4.1) on my Mac (Sierra). After the installation, I was not longer able to use my GPG combined with the YubiKey.
Checking my card status runs into the following error:



When checking the Mac console, I can see lots of entries of the process com.apple.WebKit.Networking with subsystem com.apple.securityd.


The YubiKey NEO Manager works fine. It finds my YubiKey and shows me, that the connection mode
- OTP
- CCID
- U2F
is checked.

Another important note is: If I plugin my YubiKey to a Linux system, everything is fine. So it seems to be a specific Mac problem.

I already checked this forum/web for some solutions, but wasn´t successfully so far. I don´t have an idea how to fix this.

UPDATE
Works again. What did I change? Because I installed the YubiKey PIV Manager (1.4.1) just for testing, I removed the created authentication and keyManagement certificates and restarted the machine. After I executed gpg --card-status I got the same error (Card error). I plugged in another YubiKey, executed gpg --card-status again which printed some information - as expected. Afterwards I plugged in my YubiKey and it worked again. I have no explanation for this.

Nontheless I´m very interested for the reason why I don´t want to close this ticket.

I have the same issue, but without any solution.
The same root cause.

This is how I did.

1. Delete the certificates with PIV Manager

2. Open up your Terminal
type


done!
Pull out the Yubikey and put it back, try
