If you have installed CACKey or OpenSC prior to or since you have installed PKard, then you are probably experiencing difficulties. These programs do not work together with PKard. You need to remove them from your Mac before PKard will work effectively.
Before proceeding, Quit out of any browser you may be running.
To uninstall OpenSC, open Terminal (/Applications/Utilities) and run this command
sudo /usr/local/bin/opensc-uninstall
To disable CACKey use the Finders Go > Go to Folder option, then copy this into the window: /System/Library/Security/tokend, then delete/trash the PKCS11.tokend file
Once removed, reboot your Mac and restart the Setup Assistant, which is located from the root of your hard drive /Library/Application Support/PKard/
