This can be circumvented by starting the Java JVM manually, but that is rather a complex operation to from the command line.
To help with this I've created a script called run-EazyCNC-x.y.z
To use it move the script to the same directory where you have the EazyCNC.app file.
Rename the script so that the name is of the form 'run-EazyCNC-x.y.z' where x.y.z is the EazyCNC version number (no .app at the end).
Double click the script file to start EazyCNC. That should be all. If that does not work try following: If the Terminal window does not open when you double click the script file, then right click on the script file and select "Open with..." In the "Open with" -dialog UNCHECK the "Recommend applications" and CHECK the "Always open with" and navigate to Applications/Utilities/Terminal and set that as the 'open with application'.
Try again to start EazyCNC by double clicking the script file.
If that does not help, start Terminal and do the following:
Supposing you have EazyCNC-2.0.35.app and the script named run-EazyCNC-2.0.35 in the Applications folder, type the following two commands to the Terminal:
cd /Applications
chmod a+x run-EazyCNC-2.0.35
Now try to start the application by double clicking the script file or from the Terminal by typing:
./run-EazyCNC-2.0.35
