Hello. I have the ‘bionic robot lizard kit’ and I’m following the instructions for MacOS, however I am unable to install the driver for the sunfounder nano board.

At the end of the install, I get the following message:

‘A program tried to load new system extension(s) signed by “Prolific Technology Inc.” that need to be updated by the developer.’

I am on MacOS Sonoma. Is there a workaround for this?

Thanks,  
-Mike
