bugs computers software OpenSC breaks GnuPG/SC on OSX Sep 4, 2016 CeDeROM 0 Comment If you happen to work on OSX with MacPorts and GPGTools using SmartCard for SSH then installing OpenSC (0.16.0 in my case) will break your smart card access for GPG/SSH. If you remove OpenSC with an uninstall utility things get back to normal.
