AFAIK you can choose either so called „Xcode Command Line Tools“ or „Xcode Developer Package“.

The command line tools include e.g. clang, git and python3 and SDKs. 
The disk image of version 12.2 has 431M and 14.2 has 672M. 
The unpacked files require approximately 2GB..3GB.

Without the command line tools installed there is a small python3 utility only.
The execution of this python3 triggers a popup asking the user for installation of the command line tools.

Unfortunately this popup is raised on first python presence check by LyX. 
Shortly after this LyX raises its own popup to tell the user the configuration has failed.
This 2nd popup hides the first one partially and distracts users from the first.

The easiest solution for users would be to allow download and install of the command line
tools by confirmation of the first question, wait until it is finished (it really takes a while)
and restart LyX's configuration.
