Since you provided me with more information, I will revert back to bundling since it was better :). It might be better to use wine or something that isn't MacOS. I did my best. Signing costs money and it's not cheap, so I will not be signing my apps. I know there are options in your MacOS to allow unsigned apps to run.
If you encounter a black screen, then you're not allowing it to run or not allowing the libraries to load to run. I will revert back to the bundled version. In the past, no one brought up this issue and MacOS users were able to play my game with no issues.
As for log files, they're in AppData. For MacOS, that would be /Users/<username>/Library/Application Support/FishGrid/Logs.
