I was unable to get this to work on Mac unfortunately there is no alternative to winRAR on Mac so it cannot be done. Luckily I also have a windows laptop so to get it to work I did the following. 1. backup app with imazing from Mac and save the .imazingapp file and the hacked game save into a usb drive. 2. boot up windows and add the modified file with winRAR. 3. save the modified .imazingapp file onto thumb drive. 4. go back to Mac and restore app data with imazing. Thats how I got it to work. so to all the Mac users, sorry your gonna need a windows machine until they make a actual winRAR for Mac. Thanks again for tutorial.
