It looks like you already have openjdk 17. Did you do what it asked you to do? I’m using Sonoma 14.6.1 so I don’t see the ‘unknown applications’ setting in System Settings. Usually I go to Privacy & Security and open the app there. If you want to recompile the current editor then go to the github site listed above and fork a copy of the editor to your home directory. After you’ve done that let me know and I’ll try to walk you through it. It would also help if you downloaded the ‘Home Brew’ app because you’re going to need it to help install ‘Ant’. Once you have all that it’s only a couple of lines of code in Terminal.
