Can I use a Dongle License on my Mac?

Problem description: 

Although I have installed the dongle driver from FlexNet on my Mac, I cannot use the PLECS Dongle License.

Solution: 

Yes, starting from PLECS 4.1 you can use a FlexID 10 dongle under Mac OS X. Please see our dongle page for the necessary driver.

Older FlexID 9 dongles cannot be used under Mac OS X.
