I just had the problem of removing Poker stars from my iMac.. After some research I found the app: app Cleaner to work at removing the app icon but also showing all files associated with it. You then have the option of removing everything or you can save certain files and then remove the rest. Its not an app from the App store so you must treat it by allowing it on your computer with firewall turned off. It works great and because I wasn't sure about its safety and operation I initially removed several old apps that I no longer use from my computer and it convinced me to use it. Hope this helps......
