1) Need a USB to USB-C Adaptor
2) New dongles that come in the form of USB-C
a) you can use a Adapter or Hub - we also do this on mac systems because there a very few USB Ports.b) you can also order a CmStick/D with USB/C port https://www.wibu.com/products/codemeter/cmdongle.html
Flexera does not support code meter dongles yet. So option 1 can be used by customers.
