I've ended up on here following the instructions from the installer for the community extender of AGPT, hoping to provide it the DMG for the official apple GPTK but when I followed the link in the installer, it wasn't there. I searched "GPTK and Game Porting Toolkit" to no avail. I'm running Sonoma on a 2023 M2 pro MBP with 32gb RAM, plenty powerful and up to date enough for me to have a genuine reason to use this tool. what gives? was it taken offline? if so, why?
cannot find Game Porting Toolkit in the developer site
I had this same problem. Whenever I clicked on the Download link on https://developer.apple.com/games/, it would not take me to the correct page. I tried again later, and it took me to the actual Game Porting Toolkit Download page: https://developer.apple.com/download/all/?q=game%20porting%20toolkit
I hope this helps.
