I signed up just to post that I really hope SI fix this problem - I hate losing so much screen real estate and would like the option at least to disable this in game or it just turned off completely.
I have found that the editing of the info.plist file will only break the game if not using Rosetta - so if you tick the box to say ‘run with Rosetta’ in the properties of the file, the game will launch fine and the notch won’t be ‘hidden’ (if you’ve ran the game and then edited the file, you’ll need to relog / reboot as I think the .app file gets cached or something and it’ll look like your change did nothing). Also, in your guide, you only need to edit the bottom config value (NSPrefersDisplaySafeAreaCompatibilityMode) not the top one. Obviously ignore step 8 onwards on your guide as that just resets the info file and won’t fix the issue.
I don’t want to run the game in Rosetta though so please fix this SI!
