No problem at all, the more people that get involved in the repo the better the chance of it being successful.
I now have a Windows version that Targets API 34 using Gradle 8.1.1, everything seems to be working now.
Let me know how you go on, the issues I encountered with the windows repo were, missing folder structures, not downloading the large images, ENV variables, missing files, incorrect paths etc. so the Mac version may have similar issues.
Also, the recommended Android Studio Chipmunk version is not compatible with Gradle 8.0 which is what the repo uses. I ended up using the latest version, Android Studio Iguana.
One other thing I have just remembered is that the AGKBuild.sln looks for a keystore file which was created using an alias of 'tgc' so when you create the keystore file call it keystore.keystore with an alias of 'tgc' and your own password or alternatively edit the AGKBuild.sln and change the 'tgc' to your own alias. I used Android Studio to create the keystore file.
