Hello! Just to clarify: MacOS is the operating system, while Mac Intel refers to the type of processor in your Mac.
Please make sure to check the provided “Help Guide & Tips” document and read the Installation section, especially the part related to MacOS and follow the steps exactly as described.
If you’re still having trouble after that, feel free to email me at livegameyouplay@gmail.com with a bit more info: your Mac model, the macOS version you’re using and the exact error message you’re getting. I’ll be happy to help further.
