Just a heads-up, I bought the 2020 Macbook Air (good deal $800) and it's super slow for Godot. Even 3.x is pretty choppy and 4.0 works, but is also slow. Granted, this was the cheapest one I could find that was still okay, I only use it to export and sign builds, but it would not be acceptable as my only machine. The MBP is probably a little better, but honestly, Apple products are pretty bad for game development, especially for the money. You could get a Windows/Linux laptop in the $2,000 range that would likely blow the Mac away for games, at half the price.
