After hours of trying your repo and tinwhisker repo, I decided to repport that issue. While I get no issues installing it, I don't manage to get my device detected. I get this error looping in the terminal when starting the .jar ;

This exception usually occur when the architecture is different between Java and the USB library. Make sure that your JRE and the terminal used to install are both aarch64 and not Rosetta emulated. Have a look at #50

Thanks a lot for the head's up ! Same problem, but reversed situation. I had a x64 Java on an M1 system. I got to replace the arm drivers with the x64 drivers, from the install folder to the ressources folder in the *.app. And voilà !
