Hi,
You should not try to run the app with --console that isn't working.
On mac it is located a little different.
For me it is like:
./servoy.app/Contents/MacOS/servoy --console
What should be called from terminal.
After that in console it is starting and you can do a ctrl + \ to get a console dump.. the location of the dump is usual next to the servoy executable.. but will be displayed in the console
