Greetings, the create_project.py script it is not up to date for compiling cocos2D-X on Mac OS, it does not contains the new file structure for the new version.
So , I could compile this on Mac OS, doing the following steps
1- Run the create_project.py script contained on the tools directory of the Cocos2dX distributable. After passing the specified parameters it will create the template project for many platforms , including MAC OS
2- Open the XCode project generated for Mac OS
3- In the file exploring view at Xcode , go to extensions / CocoStudio / GUI , you will find that there are files marked as red, that means that those files existed on previous versions of Cocos2Dx, but not in the latest versions, select them and delete them. Do the same in extensions / CocoStudio / System, then in that location, right click, and click on add item. Select the only two files that will show up. Just in case , check on all the folders of extensions /CocoStudio/ GUI look for red files, and delete them.
4- Go to Product / Build
5- Before running, be sure to select that you want to run your project and not cocos2dx, since it will not run.
Hope it help you. Kind regards,
