Normally, past versions of Unity can be downloaded via Unity Hub by clicking the "Unity Hub" button from the Unity download archive ( https://unity3d.com/get-unity/download/archive ). However, this method does not allow you to install Unity with Apple Silicon support. (The Intel version will be forcibly selected.) Of course, you can download and install the "Unity Editor (Apple Silicon)" and then have Unity Hub recognize it, but the directory structure will be different and I want it to do it automatically. Also, even in -headless mode, you cannot specify the Apple Silicon version of Editor.
