Hi
Thanks for your inquiry and Welcome to Centrify!
When you plug your reader(with card inserted) into your Mac, does the light on the card reader flash and/or show any activity? Normally, when the card reading LED light flashes, it should mean it's loading the content within the card.
Also, may I know what issue are you experiencing when you are trying to perform the steps (Create a new folder at: /System/Library/Security/tokend/tmp/)?
Are you seeing any error? If possible, please capture a screenshot for better understanding. Please keep us posted with any updates. Thank you!
BR,
Ivan
