For those having issues with macos, I've had success by doing the following (copy cmds from within the [] brackets and change to your actual path):
1. Download/upgrade rosetta onto your mac [softwareupdate --install-rosetta --agree-to-license].
2. Clear Gatekeeper quarantine block [xattr -cr "/Users/username/Downloads/elements_core_pack_2.14.24/generator/Elements Gen 2.1/OSX/Elements Character Generator.app"]
3. Give the application executable permissions [ "chmod -R 755 "/Users/username/Downloads/elements_core_pack_2.14.24/generator/Elements Gen 2.1/OSX/Elements Character Generator.app"]
4. Run it with the arch -x86_64 cmd [arch -x86_64 open "/Users/username/Downloads/elements_core_pack_2.14.24/generator/Elements Gen 2.1/OSX/Elements Character Generator.app"]
If you're getting errors that the app doesn't exist, it's probably because you didn't surround the full path in quotations. Hope this helps!
