I have just bought a new 24" iMac with Big Sur (previously played the game on windows PC) and have downloaded the WGT Golf app from the App Store. When you open it up it looks exactly the same as it does on the iPad/iPhone in that there is no WGT Launcher screen with the play button. The game does not use the full screen (even in Full Screen mode) and I can find no options to change this. Another problem is that if you go to the putting green, once you have finished, there is no option to get back to the main screen, the ESC key just exits the game completely. If I go to WGT.com and hit the play now button on the top left corner I get a dialog box saying safari cannot open the specified address.
