The plugin is not signed, i dont have a apple developer account to sign either.

What you can do is to de-quarantine the plugin. You can read more about over the internet on how to de-quarantine a app/plugin based on your mac os version.

Apple asks developers $100 dollars a year just to let you sign the app just to say "it is secure now", and since its a opensource project and you can read the code or even compile it your self i see no means on paying then each year $100 just to sign it.

I will update the documentation asap with notes about sign and de-quarantine since this could be a common question for mac users.

Thank you for the promptly reply and suggestion! I've managed to easily de-quarantine the JC303 plugin following the instructions found in this webpage: https://syntheway.com/fix-au-vst-vst3-macos.htm

In Summary, you just need to type this at a terminal window:

sudo xattr -rd com.apple.quarantine /Library/Audio/Plug-Ins/Components/JC303.component

Thank you for the excellent plug-in and all the hard work!!
