I should install something more? Maybe there are some drivers? \r\n\r\nWhen I plug in my key I have something like that in my logs:\r\n```\r\n11/20/15 8:45:11.000 PM kernel[0]: considerRebuildOfPrelinkedKernel prebuild rebuild has expired\r\n11/20/15 8:45:11.000 PM kernel[0]: com_driver_GxxxDriver::probe fails\r\n11/20/15 8:45:11.000 PM kernel[0]: com_driver_GxxxDriver::probe fails\r\n11/20/15 8:45:12.394 PM com.apple.SecurityServer[83]: Token reader Yubico Yubikey 4 U2F+CCID inserted into system\r\n11/20/15 8:45:12.394 PM com.apple.SecurityServer[83]: reader Yubico Yubikey 4 U2F+CCID: state changed 0 -> 34\r\n11/20/15 8:45:12.394 PM com.apple.SecurityServer[83]: token in reader Yubico Yubikey 4 U2F+CCID cannot be used (error 229)\r\n```"},"comment":{"url":"https://api.github.com/repos/Yubico/yubikey-personalization/issues/comments/158533915","html_url":"https://github.com/Yubico/yubikey-personalization/issues/71#issuecomment-158533915","issue_url":"https://api.github.com/repos/Yubico/yubikey-personalization/issues/71","id":158533915,"user":{"login":"noose","id":438968,"avatar_url":"https://avatars.githubusercontent.com/u/438968?v=3","gravatar_id":"","url":"https://api.github.com/users/noose","html_url":"https://github.com/noose","followers_url":"https://api.github.com/users/noose/followers","following_url":"https://api.github.com/users/noose/following{/other_user}","gists_url":"https://api.github.com/users/noose/gists{/gist_id}","starred_url":"https://api.github.com/users/noose/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/noose/subscriptions","organizations_url":"https://api.github.com/users/noose/orgs","repos_url":"https://api.github.com/users/noose/repos","events_url":"https://api.github.com/users/noose/events{/privacy}","received_events_url":"https://api.github.com/users/noose/received_events","type":"User","site_admin":false},"created_at":"2015-11-20T21:47:28Z","updated_at":"2015-11-20T21:47:28Z","body":"Thanks for the reply :-)"}}
