I have a couple of Processing applications exported with embedded java from Processing 3.5.4 on a Mac. I upload these in a zip file to a website for users to download on their Macs. Unfortunately on Mac OS Catalina, double clicking on the application gives an error “The application xxxxx cannot be opened”. No further explanation, and when I click the ‘?’ in the dialog box for help, the help window that opens is just blank!
I have been able to get the same apps to run on the Mac if I access a copy on my local Windows 10 Network shared folder.
Has anyone experienced a similar issue and, hopefully found a workaround?
I did try using Terminal to disable the protection using
sudo spctl --master-disable
and whilst this does enable the Allow apps downloaded from “Anywhere” option in Security & Privacy, I still get the same ‘unable to open’ error.
